Bilateral adrenal hemorrhage: learning notes from clinical practice and literature review.

Adrenal hemorrhage is a rare, but important, diagnosis to recognize, in particular when there is involvement of both adrenal glands. Bilateral adrenal hemorrhage can in fact lead to adrenal insufficiency, with dramatic consequences if not promptly recognized and treated. It is normally caused by systemic conditions that lead to the vasoconstriction and thrombosis of the adrenal vein. Oftentimes, the clinical diagnosis of this condition can be very challenging, as its signs and symptoms are generalized and nonspecific (abdominal pain, nausea, and fatigue). Here, we present the cases of two patients admitted to the Emergency Department in 2016 and 2022 with acute abdominal pain, having recently undergone surgery and subsequently prescribed low-molecular-weight heparin. In both cases, laboratory results revealed neutrophilic leukocytosis and an unexplained anemia. Due to the persistence of abdominal pain despite medication, a CT scan was performed, showing an enlargement of both adrenal glands suggestive of bilateral adrenal hemorrhage. Adrenal function was tested that correlated with a diagnosis of adrenal insufficiency, and both patients were promptly treated with parenteral hydrocortisone as a result. On 5 years' follow-up from the acute event, the second patient's adrenal function had returned to normal, and he has not needed further adrenal replacement therapy; the first patient however demonstrated persistence of adrenal failure requiring replacement therapy. In this paper, through our experience and a literature analysis, we will aim to outline some clues to identify patients at potential risk of bilateral adrenal hemorrhage.

Perinatal asphyxia and hypothermic treatment from the endocrine perspective.

Perinatal asphyxia is one of the three most important causes of neonatal mortality and morbidity. Therapeutic hypothermia represents the standard treatment for infants with moderate-severe perinatal asphyxia, resulting in reduction in the mortality and major neurodevelopmental disability. So far, data in the literature focusing on the endocrine aspects of both asphyxia and hypothermia treatment at birth are scanty, and many aspects are still debated. Aim of this narrative review is to summarize the current knowledge regarding the short- and long-term effects of perinatal asphyxia and of hypothermia treatment on the endocrine system, thus providing suggestions for improving the management of asphyxiated children. Involvement of the endocrine system (especially glucose and electrolyte disturbances, adrenal hemorrhage, non-thyroidal illness syndrome) can occur in a variable percentage of subjects with perinatal asphyxia, potentially affecting mortality as well as neurological outcome. Hypothermia may also affect endocrine homeostasis, leading to a decreased incidence of hypocalcemia and an increased risk of dilutional hyponatremia and hypercalcemia. Metabolic abnormalities in the context of perinatal asphyxia are important modifiable factors that may be associated with a worse outcome. Therefore, clinicians should be aware of the possible occurrence of endocrine complication, in order to establish appropriate screening protocols and allow timely treatment.

FRI240 Aspirin Induced Adrenal Hemorrhage: Rare Side Effect Of A Common Medication!

Abstract Disclosure: H.A. Qadeer: None. R. Samkutty: None. V. Singh: None. Introduction: Adrenal hemorrhage is a heterogeneous disorder with various clinical presentations. Bilateral adrenal hemorrhage can result in acute adrenal insufficiency that can be fatal. With the increasing use of DOAC, cases of anticoagulation therapy induced adrenal hemorrhage have been reported. We present a rare case of unilateral adrenal hemorrhage in a patient with pre-existing adrenal myelolipoma after using Aspirin. Based on our literature search, previously only two cases of Aspirin Induced adrenal hemorrhage in a stable adrenal mass have been reported. Case Presentation: 55-year-old male with history of stable 6.2 cm right adrenal gland myelolipoma, fatty liver disease and hypertension, recent use of 2 doses 81 mg Aspirin after receiving right shoulder replacement surgery presented to emergency department with acute onset right sided flank pain, constant, radiating to the back and right upper quadrant associated with an episode of vomiting. He was hemodynamically stable. Blood work showed normal electrolytes, liver function and renal function at baseline. Hemoglobin was stable around 10g/dL. CT scan abdomen/pelvis with contrast showed increase in the size of a previously stable adrenal myelolipoma to 12.9 x 15.6 cm with mass effect upon the liver. Acute hemorrhage was suspected with the blood extending beyond the margins of the mass into the right retroperitoneal space, displacing the right kidney. On admission, aspirin was discontinued. With absence of hemodynamic instability, normal electrolytes, and normal AM cortisol level of 11.9 mcg/dL, adrenal insufficiency was ruled out. Hormonal work up for hyperfunctioning adrenal tumor was performed that ruled out pheochromocytoma, Cushing syndrome and Primary Aldosteronism. With symptomatic improvement, absence of progression of adrenal hemorrhage on repeat CT scan of the abdomen/pelvis, patient was discharged home. He received IR guided embolization of the right superior adrenal artery and middle adrenal artery in the outpatient setting. Discussion: Spontaneous adrenal gland hemorrhage is a rare event. Bilateral adrenal hemorrhage is associated with acute adrenal insufficiency that can be fatal. Major risk factors for adrenal hemorrhage include anticoagulant therapy, heparin Induced thrombocytopenia, hypercoagulable state, trauma and sever sepsis. Here we have reported a rare case of adrenal gland hemorrhage with therapeutic dose of aspirin used after orthopedic surgery. Aspirin is a very commonly used medication and high index of suspicion is required to avoid this side effect as Immediate discontinuation of the medication is necessary to prevent progression of the disease. Conclusion: Aspirin use can be associated with progression of stable benign adrenal tumors by causing spontaneous hemorrhage. A high index of clinical suspicion is required for timely recognition of this side effect. Presentation: Friday, June 16, 2023

FRI175 Presentation, Etiology And Outcomes Of Adrenal Hemorrhage A Large Single-center Study

Abstract Disclosure: M. Chinthapalli: None. P. Dogra: None. R. Sandooja: None. L. Rahimi: None. N.M. Iniguez Ariza: None. T. Foster: None. I. Bancos: None. Introduction: Adrenal glands are susceptible to hemorrhage due to their unique vasculature and physiological stress response. Scarce data are available on the presentation, etiology, and outcomes of adrenal hemorrhage (AH). Objective: To describe the presentation, etiological associations, and outcomes of patients with unilateral and bilateral AH. Methods: Single-center retrospective longitudinal study of consecutive patients reported to have AH on imaging performed between January 1st 2017-December 31st 2021. Clinical, baseline and follow up imaging, and laboratory data were reviewed. Subgroup analysis was performed based on the laterality (unilateral vs. bilateral) of AH. Results: Of 454 patients with AH (median age 62 years (IQR 50-70), 160 (35%) women), 383 (85%) had unilateral AH, 60 (13%) presented with synchronous bilateral AH, and 9 (2%) had unilateral AH followed by contralateral AH at a later time (metachronous bilateral AH). Only 93 (20%) patients had an evaluation by an endocrinologist. AH was discovered incidentally in 190 (42%) patients, and during evaluation for abdominal or back pain in 133 (29%), trauma in 104 (23%), sepsis in 19 (4%), and adrenal insufficiency in 8 (2%). Primary etiology of AH was a post-procedural complication in 154 (34%), trauma in 126 (28%), coagulopathy in 54 (12%), anticoagulant or antiplatelet therapy in 52 (12%), adrenal neoplasm in 29 (6%) and sepsis in 20 (4%). Metastasis (15, 50%) represented the most common adrenal neoplasm associated with AH. In 208 (46%) patients, diagnosis of AH occurred in the hospital setting, and in 246 (54%) during an outpatient evaluation. In the 393 patients with available baseline imaging, the median size of AH was 3.1 cm (IQR 2.2-4.0). During a median imaging follow-up of 6 months (IQR 3-12), AH reduced in size with a median decrease of -2.6 cm (IQR -1.8 to -3.7) on the right and -2.0 cm (IQR -1.0 to -4.8) on the left. Compared to patients with unilateral AH, those with bilateral AH were more likely to be diagnosed in the hospital setting (61 vs. 43%, P=0.006), have an underlying coagulopathy (50 vs. 4%, P<0.0001), or sepsis (13 vs. 3%, P<0.0001), be on anticoagulant or antiplatelet therapy (48 vs. 21%, P<0.0001), develop primary adrenal insufficiency (61 vs. 0%, P<0.0001) and have larger baseline AH size (4 cm vs. left 2.7 and right 3.1 cm, P=0.0002), but a similar rate of resolution. Conclusions: AH frequently presents as unilateral hemorrhage and can occur secondary to various etiologies, with trauma and postprocedural complication being the most common. Association with an underlying adrenal mass is uncommon, seen only in 6%. Bilateral AH carries a high risk for primary adrenal insufficiency and is more likely to occur in hospitalized patients, possibly due to an increased prevalence of underlying coagulopathy, sepsis and need for anticoagulation or antiplatelet therapy.

FRI229 Bilateral Adrenal Hemorrhage Following Deep Tissue Body Massage

Abstract Disclosure: M. Antony: None. S. Gundlapally: None. P. Russell: None. S. Storm: None. S. Patel: None. V. Verma: None. R. Kant: None. Introduction: Adrenal hemorrhages have been reported in patients undergoing ACTH stimulation test using bovine- source ACTH. It can also be seen in severe stressful situations such as septicemia and extensive thermal burns due to sudden and profound adrenocortical stimulation by endogenous ACTH. Idiopathic spontaneous adrenal hemorrhage and motor vehicle accident induced adrenal hemorrhage have also been rarely reported. Coagulopathy, thromboembolic disease, and postoperative state are 3 major risk factors associated with bilateral adrenal hemorrhage. We present a unique case of a patient who presented with bilateral adrenal hemorrhage following deep tissue body massage. Clinical Case: A 44-year-old male with a past medical history of recurrent pulmonary embolism (PE) and deep venous thrombosis (DVT) due to lupus anticoagulant disorder status-post inferior vena cava (IVC) filter and recent change from Coumadin to Xarelto presented to the ED with a chief complaint of right upper quadrant (RUQ) pain extending to the right flank. Patient experienced unrelenting pain after a deep-tissue massage one week prior to presentation. Patient was seen two days prior to admission for similar complaints, but was discharged after reassuring CT abdomen/pelvis, ultrasound, and labs. He returned after pain worsened, and a repeat CT showed right adrenal hemorrhage and enlargement. Patient denied all other symptoms except pain. Vitals included BP of 144/84 mmhg, RR 20/min, HR 89/min, temp of 98.1°F, and SpO2 of 99%. Physical exam was notable only for RUQ pain and right CVA tenderness. Initial labs showed normal CBC including HGB 13.6g/dL (13-17 g/dL), HCT 37.5% (38.5-52%), and PLT 181K/microL (150-450 K/microL). Glucose 120mg/dL (70-99mg/dL), Na 129mmol/L (135-146 mmol/L), K 3.3mmol/L (3.5-5.2 mmol/L), Cl 87mmol/L (98-107 mmol/L), anion gap 17mmol/L (4-15mmol/L). LFT, serum lipase and CPK were non-contributory. PT was elevated at 24.7s (10-13s) and INR was 2.1 (0.9-1.2). Anticoagulation was stopped for three to four weeks, and nonsurgical management was recommended. Potassium supplementation was given, and the patient was continued on his hypertension medications. On further investigation, origin of the hemorrhage was determined to be traumatic secondary to the massage during which the masseuse walked on the patient. The patient was discharged after three days but was readmitted after continued abdominal pain and hyponatremia. He was diagnosed with a left-sided adrenal hemorrhage on repeat CT scan twelve days after identification of the first. Medical management was successful. Conclusion: Adrenal hemorrhage is a potentially life-threatening condition often caused by trauma, severe burns, or septicemia. Anticoagulant therapy and thromboembolic disease, as seen in our patient, are also risk factors. The atypical trauma induced by the patient's massage likely initiated the hemorrhagic event.

THU619 Atypical Clinical Presentation Of Adrenal Hemorrhage

Abstract Disclosure: T.L. Madsen-Barbosa: None. F.H. Antoni: None. A. Ghazi: None. Introduction: Adrenal hemorrhage (AH) is an uncommon condition that is challenging to diagnose due to its nonspecific findings. We illustrate a case of AH that presented with acute clinical deterioration and had catecholamine overproduction. Case: A 58-year-old woman with a history of migraine headaches and prediabetes presented to the emergency department for “the worst headache of her life” and palpitations of 4 hours duration. On admission, her blood pressure was 224/139 mmHg and heart rate was 102 bpm. Her physical examination was significant for diaphoresis and active vomiting. Initial laboratory tests showed hyperglycemia and leukocytosis. Her ECG, non-contrast CT scan of the head and CT angiography of the head and neck were unremarkable. Her hospital course was complicated by recurrent hypertensive episodes, arrhythmias including Torsades de pointes, and left flank pain. A CT chest, abdomen, and pelvis revealed a large left retroperitoneal hemorrhagic collection which seemed to arise from the inferior aspect of the left adrenal gland. She subsequently underwent successful IR embolization of the left inferior suprarenal artery. Further workup showed elevated urinary fractionated metanephrine and normetanephrine levels, as well as elevated levels of plasma free metanephrine and normetanephrine. Given concern for pheochromocytoma, phenoxybenzamine was started. A repeat CT abdomen after six days demonstrated shrinkage in hematoma and a 7 mm hypoattenuating nodule arising from the medial limb of the left adrenal gland. Outpatient follow-up CT abdomen showed left adrenal thickening with a 2.3 cm nodular area with 78.9 Hounsfield units and absolute washout of 60.9% suggestive of adenoma. After one month, repeat catecholamine levels normalized. Discussion: The clinical manifestation of AH varies widely. Acute adrenal insufficiency is seen if bilateral glands and 90% of the cortices are compromised. However, unilateral AH is most often asymptomatic - found incidentally on imaging. Having elevated catecholamines is described in 30% of patients in one case series. Differentiating spontaneous AH from hemorrhagic adrenal tumors is also a dilemma. Among the hemorrhagic adrenal masses, pheochromocytoma is the most common. Conclusion: This case highlights that clinicians should be aware of clinical manifestations of catecholamine excess when evaluating patients with AH. A catecholamine producing adrenal mass (pheochromocytoma) should also be ruled out in these situations. Reference:1- Elhassan YS, Ronchi C, Wijewickrama P, Balvedeweg SE.

FRI174 Spectrum Of Presentation Of Adrenal Incidentalomas : Is The Distribution Changing? Experience From A Tertiary Care Centre Of Eastern India

Abstract Disclosure: I. Mishra: None. M.V. Vivek: None. A.K. Baliarsinha: None. Spectrum of presentation of adrenal incidentalomas : Is the distribution changing? Experience from a tertiary care centre of Eastern India Abstract: Incidentally discovered adrenal masses have become a common clinical problem. An adrenal mass is uncovered in up to 4% -10% of patients imaged for non-adrenal disease. Incidentalomas are uncommon in patients younger than 30 years of age but increase in frequency with age; more frequently in females, especially in the sixth and seventh decades. Functioning tumors with a clear clinical phenotype (pheochromocytomas and those secreting cortisol, aldosterone, or sex steroids) and carcinomas account for around 28%- 32% of all adrenal incidentalomas. We reviewed last three year records of all the patients with the diagnosis of adrenal incidentaloma presenting to our institute and data regarding the clinical profile and outcomes of all the patients were analysed. The data obtained was entered into Microsoft Excel Worksheet and analysed using Statistical Package for Social Sciences (SPSS, IBM Corp. Released 2020.IBM SPSS Statistics for Windows, Version 20.0.Armonk,NY: IBM Corp.).Total 44 patients of adrenal incidentalomas were reviewed. In our case series, incidentalomas frequency were found to be increasing with age, most common in the 5th and 6th decades with equal frequency between male and females. Functioning tumours accounted for 54.5%(n=24), non functioning in 38.6%(n=17) and adrenal deficiciency in 6.8%(n=3)respectively. Most commonly encountered tumour was Pheochromocytoma(n=14,31.8%)followed by benign adenoma(n=10, 22.7%), adrenalcarcinoma (n=7,15.9%), myelolipoma(n=5,11.3%), aldosterone producing adenoma (n=3,6.8%), adrenal haemorrhage (n=1,2.2%), angiomyolipoma (n=1,2.2%), adrenal cyst (n=1,2.2%), and adrenal granuloma (n=2,4.5%) respectively. Amongst benign adenomas 40%(n=4) were functional( cortisol excess) and 60%(n=6) were non functional.Amongst adrenal carcinomas 42.8% (n=3) were functional and 57.2%(n=4) were non functional. Adrenal haemorrhage and adrenal granulomas had features of adrenal deficiency. The present work demonstrates that the distribution of adrenal incidentalomas is equal in both males and females, with functioning tumour Pheochromocytoma being more common than other variants. Hence the importance of complete biochemical investigation of adrenal incidentalomas is warranted. The probable changing pattern in the distribution of etiologies of adrenal incidentolomas can be further elucidated by analyzing data of a large cohort of patients with adrenal incidentolomas.

FRI179 Etiology And Morphology Of Adrenal Calcifications: Single Center Retrospective Study Of 540 Patients

Abstract Disclosure: A. Kittithaworn: None. P. Dogra: None. L. Rahimi: None. R. Sandooja: None. I. Bancos: None. Background: Adrenal calcification is discovered incidentally on imaging performed for reasons other than adrenal pathology and represents <1% of benign adrenal lesions. Data on the etiology and morphology of adrenal calcifications are scarce. Objective: To determine the etiology and imaging characteristics of adrenal calcification. Methods: We conducted a single-center retrospective study of patients with adrenal calcification on abdominal computed tomography between January 1st,2017 and December 31st, 2021. Medical records were reviewed for demographics, discovery mode, etiology and morphology. Subgroup analysis of patients with calcification/s associated with an adrenal mass was performed. Results: Adrenal calcification was reported in 540 patients (245, 45% women, median age 65 years (IQR 54-74). Only a minority of patients with adrenal calcifications were evaluated by an endocrinologist (167, 31%). Adrenal calcifications were discovered incidentally in 472 (87%) patients, during cancer staging imaging in 66 (12%), and evaluation of other symptoms in 2 (<1%). The etiology of adrenal calcification was most commonly idiopathic (390, 72%), followed by adrenal mass (112, 21%), hemorrhage (20, 6%), and granulomatous disease (8, 1.5%). Adrenal calcifications were bilateral in 34 (6%) patients and unilateral in 506 (94%), with a similar left and right distribution. Unilateral calcifications were more frequently single (399, 79%) with punctate (60%), coarse (28%), linear/curvilinear (9%), or eggshell (3%) morphology. Bilateral adrenal calcifications presented more frequently with multiple lesions (53% vs 21% in unilateral calcifications, p <0.0001), and were coarse (59%), punctate (29%), or linear (9%). When associated with either unilateral or bilateral adrenal mass, calcifications were either central (50, 45%), peripheral (44, 39%), septal (10, 9%), or both central and peripheral (7, 7%) in relation to the adrenal mass. Adrenal masses associated with adrenal calcifications were: adrenal adenomas in 63 (56%), myelolipomas or cysts in 28 (23%), metastases in 12 (11%), adrenal carcinomas in 4 (4%), pheochromocytomas in 2 (2%), and other rare masses in 3 (3%) patients. Patients with adrenal calcifications associated with an adrenal mass were younger at the time of diagnosis (median of 63 vs 66 years, p=0.014), and had a higher proportion of women (61% vs. 41%, p=0.0002), and were more likely to be discovered during cancer staging imaging (21% vs. 10%, p=0.003). Adrenal mass-associated calcifications were more frequently multiple rather than single lesions (46% vs. 17%, p<0.0001). Conclusion: Adrenal calcifications are usually unilateral single punctate or coarse lesions of unclear etiology. The majority of the adrenal masses that demonstrated calcifications were benign, however adrenal malignancy or pheochromocytomas were diagnosed in 17% of cases. Presentation: Friday, June 16, 2023

FRI212 Adrenalitis Caused By Proteus Mirabilis In An Immunocompetent Patient

Abstract Disclosure: J.O. Abdelkarim: None. U. Tarabichi: None. M. Jakoby: None. Infectious adrenalitis with Mycobacterium tuberculosis remains the leading cause of primary adrenal insufficiency in developing countries, but the incidence of adrenalitis from infection with other bacterial species is quite low. We present a patient with radiographic evidence of adrenalitis during an infection with Proteus mirabilis that resolved after antimicrobial treatment.An 86-year-old male with an indwelling Foley catheter presented to the hospital for evaluation of abdominal pain and distension. The patient was afebrile and normotensive. Examination was notable for a distended bladder and obstructed urinary catheter. Computed tomography (CT) revealed a dense right lower lobe infiltrate and bilaterally enlarged, hypointense adrenal glands with irregular margins. Radiographic findings were new compared to a CT scan obtained approximately 10 weeks before admission to hospital. Turbid and malodorous urine was drained after replacement of the patient’s urinary catheter, and urine culture grew > 105 CFU/mL Proteus mirabilis. Antibiotics were dosed before blood cultures were drawn, and no organisms were grown from blood cultures. Since there was no clinical or biochemical evidence (e.g. hyponatremia or hyperkalemia) of primary adrenal insufficiency, an ACTH stimulation test was deferred. The patient responded well to replacement of his urinary catheter and antibiotics and was discharged to his extended care facility three days later. A CT scan obtained 10 days after treatment showed resolution of the changes to the patient’s adrenal glands observed on admission imaging.The radiographic changes are most plausibly due to P. mirabilis bacteremia and adrenalitis. The patient had urine culture confirmed infection with P. mirabilis and radiographic evidence of disseminated infection in the right lung and adrenal glands. Adrenal enlargement is well described in cases of acute M. tuberculosis adrenalitis, and radiographic changes of adrenalitis resolved after successful treatment of the patient’s infection. P. mirabilis has been documented as an etiology of Waterhouse-Friderichsen syndrome and cultured from an adrenal abscess. Blood cultures in this case were almost certainly negative due to timing relative to initial antibiotic doses. Injury to the adrenals in bacterial adrenalitis is thought to occur due to multiple mechanisms including direct infection of the glands, endotoxemia, vasculitis, and disseminated intravascular coagulation (DIC). Hemorrhage appears to occur in about 60% of cases. Elevated ACTH level is postulated as a factor predisposing to adrenal hemorrhage, and this prompted deferral of stimulation testing to evaluate adrenal function since there was no clinical evidence of primary adrenal insufficiency. Early management of the patient’s infection likely prevented the occurrence of adrenal insufficiency and deterioration of his clinical status. Presentation: Friday, June 16, 2023

Imaging and outcomes of fetal adrenal hemorrhage: A systematic review.

To describe prenatal and postnatal imaging findings of fetal adrenal hemorrhage (FAH) and its associated perinatal outcomes, including frequency of postnatal surgical intervention. A systematic literature review of seven electronic databases was conducted from inception until January 2022, with 2008 articles identified reporting prenatally identified fetal adrenal masses. Studies with confirmed FAH diagnosis were included. Quality and risk assessment were evaluated. Thirty-five studies, including 102 FAH cases, were analyzed. FAH was commonly described as cystic (28/90, 31%), anechoic (25/90, 28%), or mixed echogenic (14/90, 16%) on ultrasound. Outcome data were available for 65 cases (64%) of FAH: 9% (6/65) resolved prenatally, 35% (23/65) resolved postnatally, 34% (22/65) regressed in size after birth, and 22% (14/65) persisted postnatally. Overall, 25% (16/65) of cases underwent postnatal surgical intervention. Neuroblastoma was suspected in all 16 surgical cases. Only one case (1/16, 6%) confirmed a cystic hematoma with microscopic islets of neuroblastoma in situ on pathology. Prenatal diagnosis of FAH is challenging due to the significant heterogeneity of ultrasound findings. Final pathology did not support the need for surgical intervention. Persistent postnatal FAH warrants shared decision making for further management based on the clinical presentation.

Adrenal Hemorrhage in Patients with Systemic Lupus Erythematosus and Antiphospholipid Syndrome: A Case Report and Literature Review.

Antiphospholipid syndrome (APS) is an autoimmune disorder while adrenal hemorrhage could be its rare complication. Herein, we report the case of a 32-year-old unmarried woman with a history of systemic lupus erythematosus (SLE) who was hospitalized after complaints of upper abdominal pain, limb weakness, and loss of appetite for 2 weeks. Laboratory examination revealed hyponatremia, low plasma cortisol levels, increased adrenocorticotropic hormone levels, and a positive anticardiolipin antibody status. Furthermore, computed tomography (CT) revealed the presence of bilateral adrenal masses. Ultimately, based on dynamic changes in CT images, these masses were diagnosed as adrenal hemorrhage owing to APS. A computer-assisted literature search was conducted to identify cases of primary adrenal insufficiency associated with APS and/or SLE. The clinical features, laboratory examination, treatments, and outcomes of these cases were summarized. Our findings emphasize the importance of screening for adrenal insufficiency in patients with SLE or APS who present with abdominal complaints, asthenia, and hyponatremia. It is also recommended to test for APS all patients with adrenal hemorrhage.

Outbreak of epizootic hemorrhagic disease in captive reindeer (Rangifer tarandus).

In September 2020, an outbreak of epizootic hemorrhagic disease occurred in captive reindeer (Rangifer tarandus) and was associated with neurological signs and mortality. Four reindeer died or were euthanized after acute illness over a 12-day period. Affected reindeer displayed abnormal behavior, neurologic signs, lethargy, and/or lameness. The most consistent gross finding was dark red streaks throughout the adrenal gland cortices (4/4). One animal had acute hemorrhage involving the subcutis and skeletal muscles over the ventrolateral body wall and back, and abomasal serosa. Histologically, the most common lesions were adrenal gland cortical hemorrhage (4/4) with necrosis (3/4) and lymphoplasmacytic meningoencephalitis with gliosis, glial nodules, satellitosis, and nonsuppurative perivascular cuffing (4/4). The brain lesions were most frequent in the gray matter of the cerebrum, hippocampus, and thalamus but also involved the cerebellum and brainstem. Epizootic hemorrhagic disease virus serotype 6 was detected through PCR and sequencing of the spleen in all cases.

NIEDOCZYNNOŚĆ NADNERCZY I PROCESY AUTOIMMUNOLOGICZNE W PRZEBIEGU COVID-19

SARS-CoV-2 is the cause of coronavirus disease (COVID-19). Since the beginning of the pandemic, negative effects of SARS-CoV-2 have been noted not only on the respiratory system, but also on the cardiovascular, digestive or endocrine systems. One of the organs affected by SARSCoV- 2 is the adrenal glands. Through molecular mimicry, SARS-CoV-2 contributes to inducing autoimmune processes. The virus has been shown to disrupt the hypothalamic-pituitary-adrenal axis. In addition, it can contribute to adrenal infarction and hemorrhage. The above-mentioned mechanisms may either lead to adrenal insufficiency or contribute to the exacerbation of already existing disease. However, further studies and observations of a larger number of patients are needed to determine the exact role that SARS-CoV-2 plays in inducing autoimmune adrenal insufficiency.

Cardiopulmonary Arrest Due to Idiopathic Unilateral Adrenal Hemorrhage.

Cardiopulmonary Arrest Due to Idiopathic Unilateral Adrenal Hemorrhage.

Etiology, morphology, and outcomes of adrenal calcifications in 540 adult patients-a retrospective single-center study.

Sparse data are available on the etiology, morphology, clinical presentation, and outcomes of adrenal calcification. In this single-center retrospective study of 540 consecutive patients (median age 65 years, 45% women) with adrenal calcification on computed tomography (December 2017 to January 2021), most were discovered incidentally (472, 87%). The commonest etiology was idiopathic (389, 72%), followed by the adrenal tumor (113, 21%), hemorrhage (29, 5%), and infiltrative disease (7, 1%). Calcified adrenal tumors were predominantly benign (92, 81%) and primarily adenomas (63, 69%), whereas the most common calcified adrenal malignancy (16, 18%) was metastasis (12, 67%). Calcification (unilateral 94%, bilateral 6%) morphology varied from punctate (313, 58%) to coarse (165, 30%), linear/curvilinear (46, 9%), and rim-like (16, 3%). In summary, adrenal calcifications are usually incidentally discovered unilateral, punctate, or coarse lesions of unclear etiology. Most calcified adrenal tumors are benign and <20% malignant or pheochromocytomas.

A 65-Year-Old Man with Bilateral Adrenal Hemorrhage Following Prophylaxis for Postoperative Deep Vein Thrombosis with Rivaroxaban.

BACKGROUND Direct oral anticoagulant (DOAC) agents, such as rivaroxaban, treat and prevent venous thrombosis. Although adrenal hemorrhage due to DOACs has previously been reported, this is a rare condition that can present as an emergency. In this case report, we present a 65-year-old man who recently had bilateral knee arthroplasty and was started on rivaroxaban 10 mg daily for deep vein thrombosis (DVT) prophylaxis following the surgery. CASE REPORT Ten days after bilateral knee arthroplasty and starting rivaroxaban, the patient presented to the Emergency Department with severe, sudden abdominal pain. Abdominal computed tomography detected significantly enlarged bilateral adrenals, with ill-defined heterogeneous density extending to the upper part of perinephric and paranephric spaces, suggesting bilateral adrenal hemorrhage. A cosyntropin stimulation test was used to confirm the suspicion of adrenal insufficiency. Cortisol levels were 66 nmol/L before stimulation and 83 nmol/L 60 min after cosyntropin administration. Hydrocortisone was started intravenously at a dose of 50 mg every 8 h. After his symptoms improved, he was discharged on oral hydrocortisone at 10 mg in the morning and 5 mg in the evening. Seven weeks after discharge, follow-up abdominal ultrasonography showed that the bilateral adrenal hemorrhage had resolved. CONCLUSIONS This case supports previous cases of adrenal hemorrhage as a rare but serious association with rivaroxaban and highlights the importance of rapid diagnosis using imaging and monitoring of patients for this possible adverse effect. Practitioners must remain vigilant when prescribing anticoagulation therapy, especially in patients who are at an increased risk for adrenal hemorrhage.

To Use or Not to Use? Quantifying the Benefit of Microcatheter Use in Adrenal Vein Sampling

Adrenal vein sampling is a technically difficult procedure with reported sampling success rates as low as 41%. Routine microcatheter use has been suggested by some to improve sampling adequacy. This study is a single-institution retrospective review of adrenal vein sampling procedures performed from 2014 to 2021 to quantify sample selectivity and adequacy with and without the use of a microcatheter. Microcatheter sampling was performed in 43 (47%) of 92 cases on the right adrenal gland and 44 (48%) of 92 cases on the left adrenal gland. Mean selectivity index was significantly higher bilaterally with microcatheters (right, 36.8 vs 27.7; P = .05; left, 33.9 vs 19.9 left; P < .001). However, sampling adequacy rates did not significantly differ between microcatheter and 5-F sampling bilaterally (right, 91% vs 90%; P = .88; left, 96% vs 98%; P = .51). Adrenal hemorrhage occurred exclusively with right-sided microcatheter sampling (n = 6, 13%). In conclusion, although microcatheter sampling increases mean selectivity index, it does not change sampling adequacy rate and may increase the risk of right adrenal hemorrhage.

A fatal case of fulminant group: a streptococcal infection in a neonate

BackgroundFulminant hemolytic streptococcal infection is a condition of sudden onset and rapidly progressing septic shock caused by Streptococcus pyogenes. It causes beta (complete) hemolysis. Although type A Streptococcus occurs more frequently, all streptococci that cause beta-hemolysis are eligible as causes. This report describes a rare autopsy case of fulminant group A streptococcal infection in a neonate.Case presentationA 16-day-old girl, 3300 g, born by spontaneous delivery at 41 weeks 1 day, experienced a 1-day history of low-grade fever, malaise, and a few hours of cyanosis and anuria, prompting her parents to bring her to the hospital. Her eldest brother, who lived with her, had been infected with Streptococcus approximately one month earlier, and had been treated with ten days of antibiotics. The infant died three hours after presentation. Autopsy findings indicated her to be 52 cm in length, weighing 3585 g, with medium build and normal nutrition. Her lungs were slightly oligemic with decreased volumes. The liver and kidneys were mildly enlarged. The spleen was markedly enlarged. The adrenal glands showed diffuse cortical hemorrhage (Fig. 1). There was some thymic atrophy (thymus weight 7.4 g, < 1 SD below the mean). Histopathological findings included chronic and neutrophilic infiltration of the tonsils and multiple septic emboli containing cocci in the lungs. Perivascular inflammatory cell infiltrates were observed in the lungs, myocardium, kidneys, adrenal glands, brain, meninges, and liver, with micro-necrotic changes in the kidneys and liver. Fibrin thrombi were observed in multiple renal glomeruli. Hemophagocytosis by macrophages was observed in the spleen, liver, lymph nodes, bone marrow, and adrenal glands. Immunostaining showed positive results for group A Streptococcus antibody in the tonsils, with bacterial masses. Blood cultures were positive for group A Streptococcus pyogenes.ConclusionsBecause of the lower respiratory tract infection and suspected sibling transmission, in addition to the adrenal hemorrhages, a diagnosis of fulminant sepsis with group A Streptococcus pyogenes with associated Waterhouse–Friderichsen syndrome was made.

Hemorrhage from Adrenal Vein Rupture during Adrenal Vein Sampling.

We describe a case of right adrenal hemorrhage from adrenal vein sampling treated conservatively with overnight admission and pain control. We review the existing literature on rates of this complication, typical clinical outcomes, and practical tips to avoid its occurrence.
