Chronic myeloid leukemia presenting with disc edema: A case report

The aim is to report a case of chronic myeloid leukemia (CML) in a 20-year-old female who initially presented with bilateral optic disc edema and headaches, and to raise awareness of uncommon causes of disc edema that could potentially be life-threatening. The patient first presented in June 2022 with blurry vision in the left eye, headache, and neck pain of 6 months duration. Initial examination revealed a young woman in no acute distress, with a blood pressure of 100/60 mm Hg and a body mass index of 26.98. Her pinhole visual acuity was 6/9 in both eyes, extraocular motility was full bilaterally, and both pupils were briskly reactive. However, she had bilateral optic disc edema. Both brain and orbital magnetic resonance imaging (MRI) revealed normal findings. Serological tests for syphilis and human immunodeficiency virus were negative. Based on these and the clinical features, an initial diagnosis of idiopathic intracranial hypertension was made, and the patient was started on acetazolamide tablets. She was followed up for approximately 1 year without resolution of symptoms. At a follow-up visit in December 2023, she was found to have developed dilated tortuous vessels with discrete retinal lesions. A peripheral blood film result showed that the patient had CML. In conclusion, a high index of suspicion should be entertained when managing a patient with unexplained bilateral disc swelling with normal brain MRI study. A complete blood workup, including a peripheral blood film, should be included as a part of the routine investigation of these patients so that diagnosis and treatment could be instituted early.

A rare case report on subcutaneous dirofilariasis in Kerala, South India

The genus includes vector-borne filarial nematodes, which usually infect carnivore hosts. This report aims to investigate various clinical manifestations of Human Dirofilariasis. A 44-year-old lady presented with a complaint of left neck pain of 2 weeks duration. On examination, a 2 x 2 cm swelling with tenderness was noted in the upper 1/3rd of the left sternocleidomastoid muscle. The patient was subjected to further investigations. The ultrasonography revealed a nodular lesion measuring 10.4 x 6.7 x 6.9 mm in the upper part of the left sternocleidomastoid muscle with alive moving dirofilarial worms. An excision Biopsy was performed and an HPE confirmed the diagnosis of intramuscular Dirofilariasis. In order to decrease the incidence of this disease through accurate diagnosis, and patient care, it is crucial to track the cases of human Dirofilariasis and increase awareness of these infections, diagnostic procedures, and vector control techniques.

Orthopnea secondary to brachial plexitis with bilateral diaphragmatic paralysis

BackgroundDiaphragmatic paralysis can present with orthopnea. We report a unique presentation of bilateral diaphragmatic paralysis, an uncommon diagnosis secondary to an unusual cause, brachial plexitis. This report thoroughly describes the patient’s presentation, workup, management, and outcome. It also reviews the literature on diaphragmatic paralysis and Parsonage-Turner syndrome.Case presentationA 50-year-old male patient developed insidious orthopnea associated with left shoulder and neck pain over three months with no associated symptoms. On examination, marked dyspnea was observed when the patient was asked to lie down; breath sounds were present and symmetrical, and the neurological examination was normal. The chest radiograph showed an elevated right hemidiaphragm. Echocardiogram was normal. There was a 63% positional reduction in Forced Vital Capacity and maximal inspiratory and expiratory pressures on pulmonary function testing. The electromyogram was consistent with neuromuscular weakness involving both brachial plexus and diaphragmatic muscle (Parsonage and Turner syndrome).ConclusionsCompared to unilateral, bilateral diaphragmatic paralysis may be more challenging to diagnose. On PFT, reduced maximal respiratory pressures, especially the maximal inspiratory pressure, are suggestive. Parsonage-Turner syndrome is rare, usually with unilateral diaphragmatic paralysis, but bilateral cases have been reported.

Thyroid abscess associated with thyrotoxicosis caused by Yersinia enterocolitica subsp. palearctica in a patient with follicular adenoma of the thyroid gland

BackgroundYersinia enterocolitica is a gram-negative zoonotic bacterial pathogen that is typically transmitted via the fecal-oral route. The most common clinical manifestation of a Y. enterocolitica infection is self-limited gastroenteritis. Although various extraintestinal manifestations of Y. enterocolitica infection have been reported, there are no reports of thyroid abscesses.Case presentationAn 89-year-old Japanese man with follicular adenoma of the left thyroid gland was admitted to our hospital with a 2-day history of fever and left neck pain. Laboratory tests revealed low levels of thyroid stimulating hormone and elevated levels of free thyroxine 4. Contrast-enhanced computed tomography showed low-attenuation areas with peripheral enhancement in the left thyroid gland. He was diagnosed with thyroid abscess and thyrotoxicosis, and treatment with intravenous piperacillin-tazobactam was initiated after collecting blood, drainage fluid, and stool samples. The isolated Gram-negative rod bacteria from blood and drainage fluid cultures was confirmed to be Y. enterocolitica. He was diagnosed with thyroid abscess and thyrotoxicosis due to be Y. enterocolitica subsp. palearctica. The piperacillin-tazobactam was replaced with levofloxacin.ConclusionWe report a novel case of a thyroid abscess associated with thyrotoxicosis caused by Y. enterocolitica subsp. palearctica in a patient with a follicular thyroid adenoma.

Abstract 14137: Stress-Induced Cardiomyopathy After Uncomplicated Permanent Pacemaker Implantation

Stress-induced cardiomyopathy (SCMP) after permanent pacemaker (PPM) implantation is rare. Here, we report an additional case which was initially misdiagnosed as another disease due to atypical symptoms after PPM implantation. Case presentation: A 79-year-old woman with dizziness and dyspnea for one month visited Cardiology Department. She had a history of hypertension, dyslipidemia, diabetes-mellitus and stage IV chronic kidney disease. We confirmed complete atrioventricular block. Left ventricular ejection fraction (LVEF) was normal. PPM implantation was successfully performed without complications. The next day she felt very well with no symptoms. On the second day, she suddenly developed a fever and complained severe left neck pain. She had cough, sputum and general weakness without chest pain. C-reactive protein level increased and systolic blood pressure was decreased. We started antibiotics considering infection. We also checked implantation site, but there were no signs of infection. On the third day, echocardiography showed decreased LVEF (30%), akinesia of apical and medium segments of LV wall with preserved kinetics of basal segments without pericardial effusion (Figure 1). There was no significant stenosis on coronary angiography and we confirmed SCMP. After few days, her blood pressure and symptoms were improved. We prescribed sacubitril-valsartan, bisoprolol and furosemide. At 10 days after implantation, she was discharged with improved symptoms. Conclusion: Our case emphasizes that even successful implantation of PPM without complications can be a potential risk of SCMP. In the absence of typical cardiac symptoms after PPM implantation, a poor general condition may also be considered as a sign of SCMP. Therefore, it is necessary to monitor the patient for at least three more days after PPM implantation.

FRI461 Two-years Course Of Subacute Thyroiditis After COVID-19 Vaccination: A Case Report

Abstract Disclosure: S. Yoshida: None. COVID-19 has been reported to cause subacute thyroiditis. Furthermore, the literature includes cases of COVID-19 vaccine-related subacute thyroiditis, but few reports describe the long-term course of vaccine-induced subacute thyroiditis. Herein, we report the case of a 47-year-old woman with no medical history who developed subacute thyroiditis after mRNA COVID-19 vaccination and was followed up for 2 years. Her fever persisted after the second dose of the COVID-19 vaccine, and she became aware of left anterior neck pain 8 days later. There were no infectious disease symptoms or signs in the patient’s history or at a recent physical examination. All thyroid autoantibodies were negative. On ultrasound, the thyroid gland was diffusely enlarged, and internal echogenicity was diffusely hypoechoic, coarse, and color Doppler blood flow signals were decreased without confinement to the pain area. She was diagnosed with subacute thyroiditis with tender thyroid swelling, thyrotoxicosis, and an inflammatory reaction. It was suspected that there was a causal link between the onset of subacute thyroiditis and COVID-19 mRNA vaccination because it developed immediately after vaccination and there were no other obvious causes. She was started on prednisolone, and her symptoms improved rapidly, leading to hypothyroidism 1 month later. The swelling of the thyroid gland improved rapidly, and it became atrophic several months after the onset of subacute thyroiditis. She never received any additional vaccinations. Two years after the onset, there was no recurrence of subacute thyroiditis, thyroid atrophy persisted, and the patient required levothyroxine supplementation (100 µg/day). Subacute thyroiditis generally has a good prognosis and rarely leads to permanent hypothyroidism. Subacute thyroiditis due to vaccination may follow a different course than that due to typical viral infection, and we need to examine its long-term prognosis. Presentation: Friday, June 16, 2023

Symptom Presentation among Women with Suspected Ischemia and No Obstructive Coronary Artery Disease (INOCA).

Identifying ischemic heart disease (IHD) in women based on symptoms is challenging. Women are more likely to endorse non-cardiac symptoms. More than 50% of women with suspected ischemia have no obstructive coronary disease (and thus, INOCA) and impaired outcomes during follow-up. We aimed to identify symptoms having predictive capacity for INOCA in women with clinical evidence of coronary ischemia. We included 916 women from the original WISE cohort (NCT00000554) who had coronary angiography performed for suspected ischemia and completed a 65-item WISE symptom questionnaire. Sixty-two percent (n = 567) had suspected INOCA. Logistic regression models using a best subsets approach were examined to identify the best predictive model for INOCA based on Score χ2 and AICc. A 10-variable, best-fit model accurately predicted INOCA (AUC 0.72, 95% CI 0.68, 0.75). The model indicated that age ≤ 55 years, left side chest pain, chest discomfort, neck pain, and palpitations had independent, positive relationship (OR > 1) to INOCA (p < 0.001 to 0.008). An inverse relationship (OR < 1) was observed for impending doom, and pain in the jaw, left or bilateral arm, and right hand, interpreted as INOCA associated with the absence of these symptoms (p ≤ 0.001 to 0.023). Our best-fit model accurately predicted INOCA based on age and symptom presentation ~72% of the time. While the heterogeneity of symptom presentation limits the utility of this unvalidated 10-variable model, it has promise for consideration of symptom inclusion in future INOCA prediction risk modeling for women with evidence of symptomatic ischemia.

Seronegative Isaac Syndrome Presenting as Focal Limb Stiffness Responsive to Plasma Exchange Therapy (P8-8.015)

<h3>Objective:</h3> N/A <h3>Background:</h3> Isaac syndrome is an autoimmune disorder of peripheral nerve hyperexcitability characterized by neuromyotonia, myokymia, muscles stiffness, pseudomyotonia, and pseudotetany frequently accompanied by dysautonomia and neuropathic pain. Approximately 50% of cases are associated with antibodies against contactin-associated protein-like 2 (CASPR2) or less commonly leucine-rich glioma inactivated protein 1 (LGI1), both components of the voltage-gated potassium channel (VGKC) complex. Paraneoplastic, genetic, and toxic etiologies must be considered. Management includes membrane-stabilizing drugs as well as immunotherapy in more severe cases. <h3>Design/Methods:</h3> N/A <h3>Results:</h3> A 50-year-old woman presented with one year of left neck, shoulder, and upper extremity pain and stiffness that began one month after an upper respiratory illness. Her exam was notable for anterocollis, left shoulder elevation, impaired left shoulder abduction beyond 35–40 degrees, tonically contracted left biceps, and marked tenderness to palpation of the affected muscles. Symptomatic management with diazepam, lorazepam, baclofen, mexiletine, and trihexyphenidyl was ineffective. EMG demonstrated widespread neuromyotonic discharges throughout the proximal greater than distal left upper extremity, cervical and thoracic paraspinals, and right deltoid. Laboratory studies including CASPR2, LGI1, VGKC, GAD-65, and amphiphysin antibodies were unremarkable. Comprehensive screening for occult malignancy was unrevealing. She received partial benefit from carbamazepine, levetiracetam, cyclobenzaprine, and onabotulinumtoxinA injections, but symptoms remained debilitating. She was treated with IVIg 1g/kg Q2 weeks for three months with symptom progression to the jaw and lower extremities. She was started on plasmapheresis QOD for ten days every four weeks with rapid improvement in symptoms. <h3>Conclusions:</h3> We report a case of seronegative Isaac syndrome initially presenting with focal limb stiffness and dystonic posturing that was exquisitely responsive to plasmapheresis. This case highlights the need to consider peripheral nerve hyperexcitability syndromes in patients presenting with focal limb stiffness or painful dystonia and provides additional support for plasmapheresis as an effective treatment option for patients with debilitating symptoms. <b>Disclosure:</b> Dr. Khalil has received personal compensation in the range of $0-$499 for serving as a Resident and Fellow Council Member with American Association of Neuromuscular &amp; Electrodiagnostic Medicine.

Abstract Number ‐ 76: Bow hunter’s syndrome‐ a rare case of hearing loss associated with co‐dominant vertebral artery compression

Introduction Bow hunter’s syndrome (BHS), also known as rotational vertebral artery syndrome, refers to symptomatic vertebrobasilar insufficiency (VBI) caused by mechanical compression and severe stenosis or occlusion of the vertebral artery (VA) during neck and head rotation. Etiologies include bony spurs and osteophytes, or hypertrophic muscles and ligaments compressing typically on the dominant vertebral artery. Upon turning their head, patients experience posterior circulation symptoms such as vertigo, dizziness, syncope, nausea, tinnitus, or headache. These patients are at risk of stroke due to repetitive mechanical damage to the vessel and thromboembolism. [1] We present a rare case of BHS associated with hearing loss that was caused by bony spurs compressing on a left co‐dominant vertebral artery seen on turning head to both sides. Methods A woman in her 50s presented with sporadic progressive episodes of dizziness which started about 4 years. In addition, she reported experiencing episodic tinnitus in her left ear, frequent headaches, neck pain, and syncopal episodes. She was diagnosed with severe left ear sensorineural hearing loss (SNHL). Vestibular therapy and multiple neuropathic medications (nortriptyline, gabapentin) only provided her with minimal relief. Results Examination showed left SNHL and neck tenderness. X‐ray of cervical spine showed bony hypertrophy adjacent to the dens and inferior to the anterior arch of C1, suggestive of large osteoarthritic bony spurs. CT angiogram showed narrowing of the left vertebral artery at C1 due to severe hypertrophic arthropathy of the lateral mass articulation. It also showed impingement of the left VA in the left transverse foramen. The intradural portion of the VA (V4) appeared to be co‐dominant with normal size. Dynamic cerebral angiogram revealed near occlusion of the left VA at the level of C1‐C2 with head to the right. Left VA remained patent in neutral position, and experienced reduction in flow with head rotation to the left. The dynamic stenosis of VA caused by mechanical compression upon head turn leading to VBI, and reversal of stenosis when rotating head to neutral position was consistent with diagnosis of Bow hunters syndrome. Conclusions This case report highlights a rare presentation of VBI caused by dynamic stenosis of VA as a sequela of mechanical compression of a co‐dominant VA upon head turn to both sides. Only about 2% of the BHS patients experience symptoms during head turn to both sides [2], which was the finding in our patient. Furthermore, this case illustrates an association between BHS and SNHL. Hearing loss is previously described in vertebral artery atresia [3]; however, we present a novel association between acquired BHS and SNHL. Although we could not prove the causality, the coexistence of the two conditions in this patient may help to elicit further clinical consideration and evaluation in patients with SNHL of unknown etiology.

PIK3R1, HRAS and AR Gene Alterations Associated with Sclerosing Polycystic Adenoma of the Parotid Gland

Sclerosing polycystic adenoma (SPA) is a rare neoplasm occurring in the salivary glands, mainly the parotid gland. Although it was originally thought to represent a non-neoplastic process, recent genetic data have proven its monoclonality, supporting its neoplastic origin. We report a case of a 73-year-old woman who presented with left neck swelling and pain. A 3 cm hypoechoic, heterogeneous, solid mass was identified on neck ultrasonography within the left parotid gland. Fine needle aspiration revealed benign acinar cells and lymphocytes. Left partial superficial parotidectomy was performed and a diagnosis of SPA was made. Targeted next-generation sequencing (NGS) revealed three clinically significant alterations in the PIK3R1, HRAS, and AR genes. Alterations in the PIK3R1 gene have been previously reported in cases of SPA; however, this study is the first to report two novel clinically significant genomic alterations in the HRAS and AR genes. AR protein expression by immunohistochemistry was strongly and diffusely positive in the neoplastic epithelial cells compared to the adjacent normal salivary gland tissue, which was dead negative for AR. This molecular profile will enhance our understanding of the molecular pathways underlying the development of this tumor. Although this entity was initially thought to be a reactive process, evidence from our case and similar cases strongly support the notion that it is neoplastic due to the presence of specific genetic alterations linked to it.

Linear Neck Pain and Prolonged Cough Caused by Takayasu Arteritis

The clinical manifestations of Takayasu arteritis (TA) greatly vary, and this ultimately leads to a delay in diagnosis. We describe a case of TA presenting with two coexisting rare symptoms of linear neck pain and prolonged cough. A 28-year-old Japanese female with a six-month history of ulcerative colitis presented with recurrent left neck pain, cough, and fever. The neck pain and fever started five months ago. Her symptoms briefly improved with nonsteroidal anti-inflammatory drug therapy, but eventually recurred one month prior to her latest presentation to the hospital, which was accompanied by a dry cough. Physical examination revealed a blood pressure discrepancy, with systolic blood pressure being >10 mmHg lower in her left arm than in her right arm, a bilateral carotid bruit, a weak left radial pulse and radio-radial delay without coolness in the upper extremities, and linear pulsatile tenderness in her left neck along the common carotid artery. No supraclavicular or infraclavicular bruit was noted. The erythrocyte sedimentation rate was elevated at 66 mm/hour. After obtaining the images from a contrast-enhanced computed tomography, she was diagnosed with TA. All her symptoms improved with prednisone therapy. Notably, neck pain and cough are both late-stage symptoms of TA, which are seen in 9.7% and 1.5% of patients, respectively. Although her unspecific symptoms could have been easily misdiagnosed, the recurring exacerbation of symptoms warranted careful attention to a focused physical examination.In conclusion, neck pain and cough are both uncommon presentations of TA, which may lead to physicians underdiagnosing it. It is important to recognize neck pain and cough as presenting complaints in patients with TA.

"Massive hemoptysis" and shock after fever and cough

A boy, aged 11 years, was admitted due to intermittent fever for 15 days, cough for 10 days, and "hemoptysis" for 7 days. The boy had fever and cough with left neck pain 15 days ago, and antibiotic treatment was effective. During the course of disease, the boy developed massive "hemoptysis" which caused shock. Fiberoptic bronchoscopy revealed a left pyriform sinus fistula with continuous bleeding. In combination with neck and vascular imaging examination results, the boy was diagnosed with internal jugular vein injury and thrombosis due to congenital pyriform sinus fistula infection and neck abscess. The boy was improved after treatment with temperature-controlled radiofrequency ablation for the closure of pyriform sinus fistula, and no recurrence was observed during the follow-up for one year and six months. No reports of massive hemorrhage and shock due to pyriform sinus fistula infection were found in the searched literature, and this article summarizes the clinical features, diagnosis, and treatment of this boy, so as to provide a reference for the early diagnosis of such disease and the prevention and treatment of its complications.

Association Between Neck Pain, Range of Motion, and Proprioception in Elite Female International Standard Dancers: A Case-Control Study

Neck pain is common in dancers, especially female dancers, and the injury pattern varies in different genres of dance. Among dancesport performers, intensive neck left rotation is required in female International Standard dancers, but it is unknown whether neck pain is associated with neck rotation range of motion and proprioception. To explore the associations between neck pain, cervical rotation range of motion, and proprioception in female International Standard dancers. Twelve dancers with dance-related neck pain (age 19.9±1.9 yrs) volunteered, matched with 12 not reporting neck pain (age 22.2±2.4 yrs). A 100-mm visual analog scale (VAS) was used to record neck pain. Active rotation range of motion (AROM) of the cervical spine was measured using a tape measure. A cervical rotation reposition test that used a head-mounted laser projector on a linear scale was employed to measure the cervical spine proprioception, and the absolute error (AE) and variable error (VE) were calculated as proprioceptive acuity scores. Nine of 12 participants in the group with neck pain declared left side pain, with 2 reporting pain on both sides. The group with neck pain had significantly lower left rotation AROM (p<0.05). For proprioceptive acuity, mixed model ANOVA only showed that repositioning of the right side of the neck is more accurate and consistent than that of the left (both AE and VE p<0.05). Linear regression analysis indicated that left rotation AROM was significantly influenced by left neck pain (t=3.061, p=0.006, adjusted R2 = 0.267, and Durbin-Watson value = 1.776). Most participants in the group with neck pain showed left side pain, associated with decreased left rotation AROM. Early screening on cervical rotation mobility may be necessary to reduce future dance-related injury after the onset of neck pain. Proprioceptive acuity of the left side neck was significantly impaired compared with that of the right, indicating future proprioceptive intervention on the left side neck.

Memantine in Nociceptive Pain Management: A Case Report

BACKGROUND: Memantine is a N-methyl-D-aspartate receptor antagonist that is prominently known as an Alzheimer’s disease medication. In recent years, it has started to receive attention for pain management purposes, especially for neuropathic pain. There has been little focus on its use for nociceptive pain. We present a case where the use of memantine for nociceptive pain in a patient yielded significant associated improvement. CASE REPORT: A 49-year-old man presented with a one-year history of severe nociceptive left neck pain subsequent to a whiplash injury. The patient failed multiple first-line therapies and pursued consults with multiple specialties without symptomatic improvement. He was put on memantine with subsequent sustained resolution of his nociceptive neck pain. CONCLUSIONS: Memantine’s optimal safety profile and effectiveness in this case make it important that more human patient research be conducted to further explore its efficacy for nociceptive pain. KEY WORDS: Nociceptive pain, memantine, inflammation, chronic pain, case report

Transient perivascular inflammation of the carotid artery (TIPIC) syndrome in a patient with COVID-19

A 36-year-old man with moderate-to-severe left neck pain, local swelling, and tenderness was seen at the emergency room. Over the prior 4 days he had received beta-lactam antibiotic therapy with no improvement. One month before he experienced mild symptomatic coronavirus disease 2019 (COVID-19). The PCR-based test performed at the emergency room was still positive. The remaining personal history was negative. The routine laboratory parameters were within reference range and autoimmunity screening results were negative (Table 1).

Usefulness of ultrasonography for diagnosing iatrogenic spinal accessory nerve palsy after lymph node needle biopsy: a case report

BackgroundSpinal accessory nerve (SAN) palsy is rare in clinical settings. Iatrogenicity is the most common cause, with cervical lymph node biopsy accounting for > 50% of cases. However, SAN palsy after lymph node needle biopsy is extremely rare, and the injury site is difficult to identify because of the tiny needle mark.Case presentationA 26-year-old woman was referred to our hospital with left neck pain and difficulty abducting and shrugging her left shoulder after left cervical lymph node needle biopsy. Five weeks earlier, a needle biopsy had been performed at the surgery clinic because of suspected histiocytic necrotizing lymphadenitis. No trace of the needle biopsy site was found on the neck, but ultrasonography (US) showed SAN swelling within the posterior cervical triangle. At 3 months after the injury, her activities of daily living had not improved. Therefore, we decided to perform a surgical intervention after receiving informed consent. We performed neurolysis because the SAN was swollen in the area consistent with the US findings, and nerve continuity was preserved. Shoulder shrugging movement improved at 1 week postoperatively, and the trapezius muscle manual muscle testing score recovered to 5 at 1 year postoperatively. The swelling diameter on US gradually decreased from 1.8 mm preoperatively to 0.9 mm at 6 months.ConclusionWe experienced a rare case in which US was useful for iatrogenic SAN palsy. Our results suggest that preoperative US is useful for localization of SAN palsy and that postoperative US for morphological evaluation of the SAN can help assess recovery.

Severe Unilateral Proprioceptive Loss in Medullary-rostral Spinal Cord Infarction. A Posterior Spinal Artery Syndrome

Introduction. The symptoms and signs found in patients with lateral medullary infarction have been described for more than 200 years. The major symptoms are vestibulo-cerebellar and dysphagia and dysphonia attributable to structures innervated by the ambiguous nucleus. Sensory symptoms and signs are often present in the ipsilateral face and contralateral limbs and trunk and sometimes the face. Case Report. A 29 year old woman had headache and left neck pain during weeks. Her left side suddenly became “completely dead and lacked feeling.” She saw double and was dizzy. Her right side remained normal. MRI showed infarction in the left lateral caudal medulla extending into the medulla-spinal junction. Vascular imaging showed a dissection of the left vertebral artery . Second case is A retired man with his neurological symptoms and signs developed in steps. He first noticed while shaving that his left face was numb, A week later, while showering, he became unsteady and had discomfort behind his left ear and in his left neck. MRI showed an infarct limited to the caudo-medial portion of the left dorsolateral medulla that extended into the rostral spinal cord. Discussion. Loss of position sense in the limbs ipsilateral to a medullary infarct has only rarely been reported. Lesions of the vertebral artery just above or below dural penetration are most likely to cause medullary infarcts that are tegmental rather than basal and to cause rostral spinal cord infarction. This region of the vertebral artery is rarely affected by atherosclerosis and the commonest lesion is dissection.

Metastatic rectal cancer to papillary thyroid carcinoma: a case report and review of literature

BackgroundTumor-to-tumor metastasis is a rare event. Rectal cancer to primary thyroid neoplasm metastasis is extremely rare. Herein, we reported a case of metastatic rectal adenocarcinoma to a papillary thyroid carcinoma. The incidence and clinicopathological characteristics of metastatic colorectal cancer to a thyroid gland neoplasm were described, and the pertinent literature was reviewed.Case presentationA 34-year-old female patient had curative treatment of initial rectal adenocarcinoma in 2012, and was found to have lung metastases by follow-up CT scan 3 years later. In 2018, she was found to have thyroid metastasis by imaging due to left neck pain and hoarseness. A fine-needle aspiration biopsy (FNAB) result suggested suspicious papillary thyroid carcinoma (PTC). The patient underwent a total thyroidectomy and bilateral cervical lymph nodes dissection. The histopathology of thyroidectomy specimen revealed a rectal adenocarcinoma metastatic to the thyroid concomitant with the papillary carcinoma in metastatic adenocarcinoma. The patient received levothyroxine supplementation therapy and palliative chemotherapy with irinotecan and anti-angiogenesis for the metastatic rectal adenocarcinoma. After 1 year of thyroidectomy, no newly developed lesion evidence of recurrent PTC was observed. The patient remains still alive.ConclusionThe possibility of metastases should be considered in patients with a history of rectal cancer and with a thyroid lesion, particularly in those with ageing, hereditary nonpolyposis colorectal cancer (HNPCC) or long-term survival. The diagnosis should be histologically confirmed for the presence of both primary thyroid lesions and secondary thyroid neoplasms. Thyroidectomy may be a feasible treatment for symptomatic thyroid metastasis or thyroid cancer. we need to gain more available evidence from large or multi-center clinical data to help clinicians to diagnose rectal cancer to thyroid neoplasm metastases and evaluate treatment.

Total Anterior Uncinatectomy During Anterior Discectomy and Fusion for Recurrent Cervical Radiculopathy: A Two-dimensional Operative Video and Technical Report.

A common cause of cervical radiculopathy from degenerative foraminal stenosis is severe uncovertebral hypertrophy. It is difficult to accomplish complete foraminal decompression in these cases with posterior techniques without the removal of a large portion of the facet joint. Total removal of the uncovertebral joint from an anterior approach allows for complete decompression of the exiting cervical nerve root and has been shown to be a safe technique. In this surgical video and technical report, we demonstrate the surgical anatomy and operative technique of a two-level anterior uncinatectomy during anterior discectomy and fusion (ACDF) for recurrent cervical radiculopathy after a previous multi-level posterior foraminotomy. The patient is a 67-year-old male with a progressive left arm and neck pain with radiographic, clinical, and electrophysiologic diagnostic evidence of active C6 and C7 radiculopathies from degenerative foraminal stenosis at the C5-6 and C6-7 levels. Posterior foraminotomies had been performed without significant improvement in his radicular pain. A repeat MRI demonstrated lateral foraminal stenosis from severe uncovertebral joint hypertrophy at the C5-6 and C6-7 levels. After acquiring informed consent from the patient, an anterior approach was performed with complete removal of the uncovertebral joints at both levels with discectomy and fusion. Postoperatively, the patient had complete resolution of his radicular pain and remained pain-free at the latest follow-up. Complete uncinatectomy and ACDF is an effective technique for complete foraminal decompression in cases of refractory radiculopathy and neck pain after unsuccessful posterior decompression.

Case 3: Rapidly Expanding Neck Mass Leading to Cardiopulmonary Arrest in a 14-year-old Boy.

1. Stanley Lee, MD* 2. Ahmed Aly, MBBS* 3. Paayal Bhakta, MD* 4. Karthikeyan Parameswaran, MBBS* 5. Valeriy Chorny, MD* 6. Rohit Pinto, MD* 7. Jianying Zeng, MD† 8. Richard Hong, MD‡ 9. Melvyn Braiman, MD* 1. *Department of Pediatrics, 2. †Department of Pathology, and 3. ‡Department of Radiology, SUNY Downstate Medical Center and Kings County Hospital Center, Brooklyn, NY A 14-year-old boy is transferred from an outside hospital with a 1-day history of severe left upper neck swelling and pain without any known precipitating factors. Three years ago the patient had a similar episode: a painful left neck mass was diagnosed as lymphadenitis and treated with amoxicillin without sequelae. In the emergency department, vital signs and a complete blood count are within normal limits. The mass is soft and tender to palpation, measuring 1.0 × 1.5 cm. A computed tomographic (CT) scan with contrast reveals an expansile lesion stemming from the left aspect of the hyoid bone compressing the trachea (Fig 1). The ENT team performs a bedside laryngoscopy and confirms a rightward tracheal deviation and compression. Figure 1. Expansile lesion of the hyoid bone causing a rightward tracheal deviation. A computed tomographic scan of the neck revealing a 1.3-cm lesion from the left hyoid bone (blue arrow) with an associated 11.2-cm soft tissue mass expanding through the thoracic outlet. The lesion led to a rightward tracheal deviation and compression (red arrow). On admission to the inpatient unit, the patient is alert, oriented, and in mild distress due to pain, but his vital signs remain within normal limits. The neck mass remains very tender to palpation and has expanded to 4.0 × 5.0 cm on physical examination, a few hours after the initial measurement. His neck has limited movement, and there are no signs of respiratory distress, stridor, drooling, or retractions. He is able to speak in full sentences. He has some difficulty in swallowing solids but is tolerating liquids. He is started on …
