A retrospective cohort study on a novel marker to predict the severity and prognosis of acute cerebral venous thrombosis: D-dimer to fibrinogen ratio

Background and aimThe D-dimer to fibrinogen ratio (DFR) represents an emerging and significant clinical biomarker. However, its correlation with cerebral venous thrombosis (CVT) remains underexplored. This retrospective cohort study aims to elucidate the association between DFR values and the severity and prognosis of CVT.MethodsSevere CVT was defined as the presence of at least 1 of the following risk factors: mental status disorder, coma state, intracranial cerebral hemorrhage, or thrombosis of the deep cerebral venous system. The modified Rankin Scale was utilized to assess functional outcomes. DFR measurements were obtained within 24 h of hospital admission. Logistic regression analysis was employed to determine the prognostic significance of DFR. After Bonferroni correction, a two-tailed P value < 0.017 (0.05/3) was considered statistically significant.ResultA total of 196 patients were included in the study, among whom 85 patients were diagnosed with severe CVT, and 35 and 14 patients experienced short-term and long-term adverse outcomes, respectively. Receiver operating characteristic curve analysis demonstrated that DFR has predictive value for severe CVT, poor short-term and long-term outcomes, with area under the curve values of 0.690 [95% CI: 0.617–0.764, P < .001], 0.773 [95% CI: 0.701–0.845, P < .001], and 0.754 [95% CI: 0.619–0.886, P = .002], respectively. DFR ≥ 0.253 was identified as a significant predictor of severe CVT [adjusted odds ratio (aOR) (95% CI): 2.03 (1.10–3.75), P = .024]. Additionally, DFR ≥ 0.322 and DFR ≥ 0.754 were significantly associated with poor short-term outcomes at discharge [aOR (95% CI): 2.63 (1.43–4.76), P = .002] and poor long-term outcomes at 12 months [aOR (95% CI): 2.86 (1.32–6.25), P = .008], respectively.ConclusionElevated DFR is associated with increased severity of CVT. Additionally, higher DFR levels can predict poorer clinical outcomes in CVT.

The evaluation of complete blood count parameters in the patients with idiopathic versus secondary cerebral venous thrombosis

Background: Several laboratory markers derived from a complete blood count (CBC) have been proposed as potential indicators for assessing the risk of cerebral venous thrombosis (CVT). However, limited and conflicting evidence exists regarding this association. This study aimed to evaluate the role of CBC parameters in CVT development and their link to disease characteristics. Methods: This case-control study included patients diagnosed with CVT between March 2018 and and March 2021. All participants with CVT were registered in the organized registry system at the Neurology Research Center of Shiraz University of Medical Sciences, Shiraz, Iran (CVT registry code: 9001013381). The control group consisted of age- and sex-matched individuals without systemic diseases. CBC results from the control group and the first recorded hospital CBC of the patient group were collected. Results: The study included 295 patients with CVT [49 with idiopathic CVT (iCVT) and 246 with secondary CVT (sCVT)] and 341 healthy individuals. Among the CVT group, 72.54% were women. Patients with CVT had higher red cell distribution width (RDW) and lower red blood cell (RBC) count, hemoglobin (Hb) levels, and hematocrit compared to the non-CVT group. In iCVT cases, male gender, RBC count, Hb levels, and hematocrit were notably higher compared to sCVT cases. Logistic regression analysis showed that female gender, smoking, and higher hematocrit values were associated with increased probability of iCVT. Conclusion: The study suggests that certain CBC parameters may serve as potential markers for assessing CVT risk and differentiating between iCVT and sCVT cases. Validation and further research are needed to explore the underlying mechanisms.March 2021.

Diagnostic potential of lncRNAs-ANRIL and MIAT in the blood of patients with cerebral venous thrombosis

Background: Long non-coding ribonucleic acids (lncRNAs) have been implicated as possible circulating stroke indicators. This study focused on the expression status of antisense non-coding ribonucleic acid in the INK4 locus (ANRIL) and myocardial infarction associated transcript (MIAT) in patients with cerebral venous thrombosis (CVT). Methods: In this study, fifty patients with CVT and one hundred age/gender-matched individuals as controls were included. The circulating levels of ANRIL and MIAT in the first 24 hours after admission were evaluated using the quantitative real-time polymerase chain reaction (RT-PCR) method. We compared the expression levels of ANRIL and MIAT between patients and controls using the independent two-sample t-test. Subgroup analysis was used to investigate the association of lncRNAs with clinical characteristics in patients with CVT. Receiver operating characteristic (ROC) curve analyses were conducted to evaluate the diagnostic value of two lncRNAs in patient assessment. Results: The relative expression of lncRNAs ANRIL and MIAT significantly decreased in patients compared to the control. ANRIL and MIAT were shown as potential markers for discriminating patients with CVT from the healthy controls with an area under the curve (AUC) of 0.98 and 0.99, respectively. Conclusion: For the first time, we found down-regulation and diagnostic potential of lncRNAs-ANRIL and MIAT in the blood of patients with CVT.

Dual-energy CT angiography in detecting underlying causes of intracerebral hemorrhage: an observational cohort study.

CT angiography (CTA) is often used to detect underlying causes of acute intracerebral hemorrhage (ICH). Dual-energy CT (DECT) is able to distinguish materials with similar attenuation but different compositions, such as hemorrhage and contrast. We aimed to evaluate the diagnostic yield of DECT angiography (DECTA), compared to conventional CTA in detecting underlying ICH causes. All non-traumatic ICH patients who underwent DECTA (both arterial as well as delayed venous phase) at our center between January 2014 and February 2020 were analyzed. Conventional CTA acquisitions were reconstructed ('merged') from DECTA data. Structural ICH causes were assessed on both reconstructed conventional CTA and DECTA. The final diagnosis was based on all available diagnostic and clinical findings during one-year follow up. Of 206 included ICH patients, 30 (14.6%) had an underlying cause as final diagnosis. Conventional CTA showed a cause in 24 patients (11.7%), DECTA in 32 (15.5%). Both false positive and false negative findings occurred more frequently on conventional CTA. DECTA detected neoplastic ICH in all seven patients with a definite neoplastic ICH diagnosis, whereas conventional CTA only detected four of these cases. Both developmental venous anomalies (DVA) and cerebral venous sinus thrombosis (CVST) were more frequently seen on DECTA. Arteriovenous malformations and aneurysms were detected equally on both imaging modalities. Performing DECTA at clinical presentation of ICH may be of additional diagnostic value in the early detection of underlying causes, especially neoplasms, CVST and DVAs.

Revisiting Virchow’s triad: exploring the cellular and molecular alterations in cerebral venous congestion

BackgroundCerebral venous thrombosis (CVT) is a rare but serious condition that can lead to significant morbidity and mortality. Virchow’s triad elucidates the role of blood hypercoagulability, blood flow dynamics, and endothelial damage in the pathogenesis of CVT. Cerebral venous congestion (CVC) increases the risk of cerebral venous sinus thrombosis and can lead to recurrent episodes and residual symptoms. However, the precise mechanism by which blood congestion leads to thrombosis remains unclear. Our objective was to investigate the cellular and molecular alterations linked to CVC through analysis of the pathological morphology of venous sinus endothelial cells and transcriptomic profiling.ResultsThis study demonstrated a remarkable correlation between CVC and the phenotypic transformation of endothelial cells from an anticoagulant to a procoagulant state. The findings revealed that cerebral venous stasis results in tortuous dilatation of the venous sinuses, with slow blood flow and elevated pressure in the sinuses and damaged endothelial cells of the retroglenoid and internal jugular vein ligation (JVL) rat model. Mechanistically, analysis of transcriptomic results of cerebral venous sinus endothelial cells showed significant activation of platelet activation, complement and coagulation cascades pathway in the JVL rats. Furthermore, the expression of von Willebrand factor (vWF) and coagulation factor VIII (F8) in the complement and coagulation cascades and Fgg and F2 in the platelet activation was increased in the cerebral venous sinuses of JVL rats than in sham rats, suggesting that endothelial cell injury in the venous sinus induced by CVC has a prothrombotic effect. In addition, endothelial cell damage accelerates coagulation and promotes platelet activation. Significantly, the concentrations of vWF, F2 and F8 in venous sinus blood of patients with internal jugular vein stenosis were higher than in their peripheral blood.ConclusionCollectively, our data suggest that CVC can induce endothelial cell damage, which then exhibits a procoagulant phenotype and ultimately increases the risk of CVT. This research contributes to our understanding of the pathophysiology of CVC associated with procoagulant factors and reexamines the components of Virchow’s triad in the context of CVC.

Update on management of cerebral venous thrombosis.

This review intends to systematize the diagnostic and treatment approach to cerebral venous thrombosis (CVT), highlighting key studies that have been recently published. In light of the recent pandemic, new risk factors for CVT have emerged. Contrast-enhanced MRI and susceptibility-weighted imaging have been shown to offer increased sensitivity for detecting cortical vein thrombosis.Dabigatran seems to be as effective and well tolerated as warfarin for long-term anticoagulation. Partial venous recanalization often occurs in patients treated with anticoagulation only, as early as 8 days after treatment onset. For patients with CVT and impending brain herniation, two-thirds of those who undergo decompressive craniectomy survive, with one-third being functionally independent 6 months after diagnosis. CVT is an unusual type of cerebrovascular disease that mostly affects women of fertile age. Risk factors should be identified and addressed. Diagnosis relies on confirmation of venous sinus and/or vein thrombosis, usually by CT venography or MRI. Anticoagulation is the cornerstone of treatment. Despite the lack of high-quality evidence, endovascular treatment is often considered in severe cases. Special populations require tailored approaches. About 80% achieve mRS 0-1, but residual symptoms often affect quality of life and the ability to return to work.

Development and Validation of a Clinical Score to Predict Epilepsy After Cerebral Venous Thrombosis

One of 10 patients develop epilepsy in the late phase after cerebral venous thrombosis (CVT) diagnosis but predicting the individual risk is difficult. To develop and externally validate a prognostic score to estimate the individual risk of post-CVT epilepsy. This observational cohort study included both retrospective and prospective patients enrolled from 1994 through 2022. For development of the DIAS3 score, data from the International CVT Consortium (n = 1128), a large international hospital-based multicenter CVT cohort, were used. For validation, data from 2 independent multicenter cohorts, the ACTION-CVT (n = 543) and the Israel CVT study (n = 556), were used. Of 2937 eligible, consecutively enrolled adult patients with radiologically verified CVT, 710 patients with a history of epilepsy prior to CVT, follow-up less than 8 days, and missing late seizure status were excluded. The prediction score (DIAS3) was developed based on available literature and clinical plausibility and consisted of 6 readily available clinical variables collected during the acute phase: decompressive hemicraniectomy, intracerebral hemorrhage at presentation, age, seizure(s) in the acute phase (excluding status epilepticus), status epilepticus in the acute phase, and subdural hematoma at presentation. Time to a first late seizure, defined as occurring more than 7 days after diagnosis of CVT. Of 1128 patients included in the derivation cohort (median age, 41 [IQR, 30-53] years; 805 women [71%]), 128 (11%) developed post-CVT epilepsy during a median follow-up of 12 (IQR, 3-26) months. According to the DIAS3 score, the predicted 1-year and 3-year risk of epilepsy in individual patients ranged from 7% to 68% and 10% to 83%, respectively. Internal and external validation showed adequate discrimination in the derivation cohort (1 year and 3 years: C statistic, 0.74; 95% CI, 0.70-0.79) and the 2 independent validation cohorts, (ACTION-CVT) 1 year: C statistic, 0.76; 95% CI, 0.67-0.84; 3 years: C statistic, 0.77; 95% CI, 0.66-0.84; and Israel CVT study 1 year: C statistic, 0.80; 95% CI, 0.75-0.86. Calibration plots indicated adequate agreement between predicted and observed risks. The DIAS3 score (freely available online) is a simple tool that can help predict the risk of post-CVT epilepsy in individual patients. The model can improve opportunities for personalized medicine and may aid in decision-making regarding antiseizure medication, patient counseling, and facilitation of research on epileptogenesis in CVT.

Biallelic PIGM Coding Variant Causes Intractable Epilepsy and Intellectual Disability Without Thrombotic Events.

During the past two decades, an emerging group of genes coding for proteins involved in glycosylphosphatidylinositol (GPI) anchor biosynthesis are being implicated in early-infantile epileptic encephalopathy. Amongst these, a hypomorphic promoter mutation in the mannosyltransferase-encoding PIGM gene was described in seven patients to date, exhibiting intractable absence epilepsy, portal and cerebral vein thrombosis and intellectual disability (ID). We describe here three siblings exhibiting intractable epilepsy and ID, found to harbor a homozygous c.224G>A p.(Arg75His) missense variant in PIGM, which segregated with the disease in the family. The variant is evolutionary conserved, extremely rare in general population databases and predicted to be deleterious. Structural modeling of the PIGM protein and the p.(Arg75His) variant indicates that it is located in a short luminal region of the protein, predicted to be hydrophilic. Functional prediction suggests that the entire local region is sensitive to mutations, with the p.(Arg75His) variant in particular. This is the first report of a PIGM coding variant, and the second variant altogether to be described affecting this gene. This phenotype differs from that of patients with the shared PIGM promoter mutation by lack of thrombotic events and no decrease in PIGM cDNA levels or CD59 expression on red blood cells.

Cerebral Venous Thrombosis in a Young Adult: A Case Report Highlighting Thrombophilia and Epilepsy Management

Cerebral venous thrombosis (CVT) is a rare but serious condition that can lead to significant neurological complications if not promptly diagnosed and treated. This case report describes a 23-year-old male with a history of epilepsy, managed with sodium valproate, who presented with a sudden, severe headache and visual disturbances. Imaging revealed a linear filling defect in the straight sinus, consistent with CVT. Further investigation uncovered deficiencies in protein S and C, indicating an underlying thrombophilic condition. The patient was successfully treated with anticoagulation therapy, initially with enoxaparin followed by oral apixaban, resulting in the complete resolution of symptoms. This case shows the importance of considering thrombophilia in patients with CVT, especially those with a history of epilepsy, and demonstrates the effectiveness of early intervention with anticoagulants in achieving positive outcomes.

Cerebral venous sinus thrombosis - Current updates in the Asian context.

Background Cerebral venous sinus thrombosis (CVT) is a life-threatening cause of stroke in Asian countries. South Asia, comprising of India, Pakistan and Bangladesh and contributed to 40% of strokes in women. Major CVT registries are from the western nations, which differs from the Asian countries with respect to epidemiology, gender biases and risk factors. This review focusses on the various aspects of relevance in evaluation and management of patients with CVT in the Asian context. Summary The incidence of CVT is higher in Asia than in Western nations. Young age, female gender, especially in pregnancy and puerperal period, and dehydration appear to be the critical risk factors. Tropical infections like malaria, scrub typhus, and flaviviral encephalitis predispose to CVT. There is a higher prevalence of inherited thrombophilia in the Asian cohorts, contributing to prothrombotic states. Anticoagulation and supportive management offer excellent outcomes. Newer anticoagulants are safe and efficacious. In medically refractory cases, endovascular treatment offers modest benefits. Decompressive hemicraniectomy, when done early, offers mortality benefits in patients with large hemorrhagic venous infarctions. Key messages CVT is an important cause of stroke with high-burden in South Asian countries. Establishment of robust registries is the need of the hour; to study the natural history, course and outcomes and to develop management algorithms tailored to the available resources.

Sinus vein thrombosis conundrum: Persistent empty sella vs. flexible optic nerve sheath

IntroductionOur objective was to investigate the potential effect of thrombotic burden on pituitary gland height, bony sella and optic sheath width, taking into consideration the various venous sites and dominant drainage pattern. Patients and MethodsThis retrospective cohort study followed patients diagnosed with cerebral sinus vein thrombosis in a single primary healthcare center between the years 2000 and 2022. Data was collected from both CT/V and MR/V scans available on the local PACS system. Dural sinuses were divided into main anatomical sites and scored for patent, partially or totally blocked lumen. Dominant drainage flow was noted for each patient. For most scans, pituitary mid height, maximal depth and AP width of the bony sella and dorsum sella to tuberculum sella distance were assessed. Optic sheath width was measured for both sides at the maximal retrobulbar diameter. Regression methods, including linear mixed models, and non-parametric tests were used to analyze the data. Results90 patients (mean age, 44 years ±16.8, 54 women) were evaluated. Overall thrombus burden did not correlate with pituitary mid-height, however a relationship was observed between the change (from presentation) in the superficial thrombus score and the average width of the optic nerve sheath; the width of the optic sheath tended to decrease as thrombus burden improved and vice versa (p = 0.010). ConclusionsThrombus recanalization had a favorable effect on the optic nerve sheath diameter but did not appear to reverse the flattening of the pituitary gland, regardless of temporal improvement.

Rituximab induced cerebral venous sinus thrombosis in a patient with anti-N-methyl-d-aspartate receptor-antibody encephalitis: a case report and review of literature

BackgroundCerebral venous sinus thrombosis has not been reported in anti-N-methyl-d-aspartate receptor-antibody encephalitis in the absence of an underlying thrombotic state while rituximab induced cerebral venous sinus thrombosis is rarely reported. We report a patient with anti-N-methyl-d-aspartate receptor-antibody encephalitis without a prothrombotic state who developed cerebral venous sinus thrombosis following rituximab treatment.Case presentationA 15-year-old Sri Lankan girl who had been in remission following an episode of anti-N-methyl-d-aspartate receptor-antibody encephalitis 2 years ago, presented with a relapse of anti-N-methyl-d-aspartate receptor-antibody encephalitis characterized by recurrent seizures, mutism, and cognitive abnormalities. Since response was inadequate to first-line immunotherapy, she was administered four doses of rituximab at weekly intervals. Two days after the fourth dose, she developed increasing headaches, and her cranial magnetic resonance venogram confirmed the development of cerebral venous sinus thrombosis. Screening for prothrombotic states were negative. She made an unremarkable recovery following anticoagulation.ConclusionThis case highlights the occurrence of the rare but serious complication of cerebral venous sinus thrombosis following rituximab in the context of anti-N-methyl-d-aspartate receptor-antibody encephalitis and informs the clinician to be wary of new onset headache in patients with anti-N-methyl-d-aspartate receptor-antibody encephalitis treated with immunotherapy.

Pregnancy-related intracranial venous sinus thrombosis secondary to cryptococcal meningoencephalitis: a case report and literature review

BackgroundCerebral venous sinus thrombosis (CVST), a serious cerebrovascular and neurological emergency, is common in pregnant individuals and accounts for approximately 0.5–1.0% of all cerebrovascular diseases. However, CVST with cryptococcal meningoencephalitis in immunocompetent pregnant patients is rare.Case presentationA 30-year-old woman who was 33 weeks pregnant presented with recurrent dizziness, headache, and vomiting as the main clinical manifestations, all of which were initially nonspecific. After assessment of the cerebrospinal fluid, skull computerized tomography, magnetic resonance imaging, and other laboratory and imaging examinations, the patient was diagnosed with secondary pregnancy-related CVST with cryptococcal meningoencephalitis. Despite receiving potent anticoagulant and antifungal treatment, the patient’s condition deteriorated, and the patient’s family opted to cease treatment.ConclusionsWe present a rare case of CVST with cryptococcal meningoencephalitis in an immunocompetent pregnant patient. The difficulty of diagnosing and treating secondary pregnancy-related CVST caused by cryptococcal meningoencephalitis, as well as the great challenges faced at present are highlighted. One crucial lesson from the present case is that when clinical and imaging signs are unusual for CVST during pregnancy, it is essential to account for the possibility of other central nervous system (CNS) diseases, such as CNS infections with Cryptococcus, which may cause CVST.

Cerebral venous sinus thrombosis associated with JAK2 V617F mutation-related pre-primary myelofibrosis: a case report and literature review

BackgroundCerebral venous sinus thrombosis (CVST) is a rare but potentially life-threatening subtype of stroke. Prompt and appropriate anticoagulation is crucial for improving the prognosis of CVST and preventing its recurrence. Identifying the underlying cause of CVST is decisive for guiding anticoagulant selection and determining treatment duration.Case PresentationA 50-year-old man presented with a 35-day history of headache, nausea, vomiting, and blurred vision. Digital subtraction angiography performed at another facility revealed CVST. A contrast-enhanced black-blood MRI at our center confirmed the diagnosis, which was supported by a high intracranial pressure of 330mmH2O. Laboratory tests showed elevated leukocytes and platelet counts, raising suspicion of an underlying myeloproliferative neoplasms (MPNs). A bone marrow biopsy demonstrated increased megakaryocytes and granulocytes, and genetic testing identified the presence of the Janus kinase 2 V617F (JAK2 V617F) mutation, leading to a diagnosis of pre-primary myelofibrosis (pre-PMF). During hospitalization, anticoagulation with nadroparin calcium and fibrinolytic therapy were initiated. Upon discharge, rivaroxaban and aspirin were prescribed to prevent CVST recurrence and arterial thrombosis.ConclusionThis case highlights the importance of recognizing dynamic changes in routine blood tests that may link CVST to underlying hematological disorders. The JAK2 mutation is not only associated with MPNs but also increases the risk of thrombosis, including CVST. Further investigation is warranted to better understand the mechanisms by which JAK2 mutations contribute to thrombosis and to explore the potential benefits of JAK2 inhibitors in reducing this risk.

Novel SERPINC1 Mutation in a Brazilian Patient with Sudden-onset Sagittal Sinus Thrombosis Caused by Congenital Antithrombin Deficiency

A 19-year-old Brazilian man visited the emergency department of our hospital complaining of nausea and fever. He presented with left hemispatial neglect. Magnetic resonance imaging led to a diagnosis of sagittal sinus thrombosis. Blood tests showed decreased antithrombin (ATIII) activity, and ATIII deficiency was diagnosed. He was treated with heparin sodium and warfarin. Genetic counseling through medical interpreters was recommended, and the patient and his mother consented to genetic testing, which revealed a novel mutation variant of the SERPINC1 gene. Genetic counseling is important to connect patients to genetic testing, even if language barriers are present.

Cerebral Venous Thrombosis in a Term Child: A Case Report

Thrombosis of cerebral venous sinuses is a rare condition but can be associated with serious clinical consequences. Pathogenesis of thrombosis of cerebral venous sinus is still not clear. As there is diverse etiology but presentation is subtle, it often leads to delay in the diagnosis. We are reporting the case of a term male neonate born by LSCS (indication obstructed labour with meconium stained amniotic fluid) with diagnosis of severe birth asphyxia, Hypoxic Ischemic Encephalopathy- stage II, probable sepsis, shock and Germinal Matrix Haemorrhage. The magnetic resonance imaging (MRI) of brain and magnetic resonance (MR) venogram done at 2 weeks of age showed superior saggital sinus thrombosis. Baby received anticoagulation therapy and extensive workup was done. Early neuroimaging in all the babies who has neonatal seizures will improve the identification and will warrant early treatment.

A case of convexity non-aneurysmal subarachnoid hemorrhage caused by cerebral sinus thrombosis

BackgroundConvexity subarachnoid hemorrhage (cSAH) is an uncommon presentation of subarachnoid bleeding, referring to bleeding more localized to the convexities of the brain. The diagnosis of cerebral venous sinus thrombosis (CVST) can be difficult especially when patients initially present with cSAH. The authors present a case and then discuss the pathophysiology and management.Case presentationA 56-year-old woman with a previous history of hypertension and ischemic heart disease presented to the emergency department after experiencing it. Two seizures following a severe headache. The patient’s history was negative for recent illnesses, head trauma, history of migraines, smoking, alcohol consumption, or intravenous drug use. The patient was diagnosed with CVST based on magnetic resonance venography (MRV). Genetic studies further identified homozygous mutations in the Prothrombin and MTHFR genes. Anticoagulant therapy was initiated with 60 mg of Enoxaparin twice daily and subsequently transitioned to Warfarin after 48 h continued for 3 months, and then replaced by rivaroxaban.ConclusionsThis study highlights the importance of considering CVST as a cause of SAH, emphasizes the role of advanced imaging in diagnosis, and demonstrates a successful treatment approach using both traditional and direct oral anticoagulants. The insights provided in this article can contribute to improving the management of patients with CVST-related SAH.

Trombóza mozkových splavů jako primomanifestace adenomu příštítného tělíska

Primary hyperparathyroidism (HPPT) is a generalized disorder of calcium-phosphate metabolism resulting from long-term secretion of parathyroid hormone (PTH). The most common cause of PTH overproduction is an adenoma of one or more parathyroid glands. Cerebral venous sinus thrombosis accounts for about 1–2% of cerebral events and its consequence can be focal ischemia with intracerebral hemorrhage. In this article, we describe a unique case report of a patient who was urgently admitted for the progression of a sudden speech disorder and progressive impairment of consciousness on the basis of thrombosis in the cerebral sinuses and intracerebral hemorrhage. Secondary findings at the initial diagnostic process were hypophosphatemia and hypercalcemia with parathyroid hormone elevation.

Superior Sagittal Sinus Thrombosis Secondary to Cerebral Aspergillosis with Ventriculitis in an Immunocompetent Patient: A Case Report

AbstractCerebral aspergillosis is an opportunistic fungal infection that is exceedingly rare in immunocompetent patients. The primary etiological locations for these infections typically involve the nasal cavity and hematological dissemination. A 62-year-old male, focused on wellness, presented with intermittent, nonprogressive headaches in the occipital region, generalized clonic–tonic seizures, and altered consciousness. A computed tomography scan revealed multiple small rim-enhancing lesions in both occipital lobes, with vasogenic edema in both occipital lobes adjacent to the confluence of the sinuses and the posterior superior sagittal sinus. In this case, superior sagittal sinus thrombosis secondary to cerebral aspergillosis was discovered, a condition not previously diagnosed in this specific location but manageable through surgical intervention. A combination of surgical resection and antifungal therapy resulted in favorable outcomes. The prognosis for patients depends significantly on early diagnosis and prompt, aggressive treatment.
