BACKGROUND AND PURPOSE MR venography is often used to examine the intracranial venous system, particularly in the evaluation of dural sinus thrombosis. The purpose of this study was to evaluate the use of MR venography in the depiction of the normal intracranial venous anatomy and its variants, to assess its potential pitfalls in the diagnosis of dural venous sinus thrombosis, and to compare th...

A 65-year-old woman with poorly controlled diabetes presented bilateral miosis, bilateral abducens nerve palsy, and left hemiparesis. On MRI, cavernous sinus thrombosis, subdural empyema and hemorrhagic infarction in the frontotemporal lobe were detected. Cerebral angiogram revealed filling defect in the cavernous sinus with venous congestion but no involvement of internal carotid artery. Postm...

A 43-year-old woman, presented with headache, reduced visual acuity, for 5 days and bilateral papilledema. Non-enhanced cerebral computed tomography (CT) was normal. The venous angiography-CT revealed the empty delta sign within superior sagittal, right transverse and sigmoid sinuses, characterizing sinus thrombosis (Figure). The empty delta sign is a central intraluminal filling defect, repres...

BACKGROUND AND PURPOSE The diagnosis of cerebral venous and sinus thrombosis (CVST) as a rare but important cause of stroke is challenging. We aimed to investigate the diagnostic value of multidetector-row CT angiography (MDCTA) as a fast and cost-effective imaging tool in diagnosing CVST. MATERIALS AND METHODS Nineteen patients who presented with clinical symptoms of a possible CVST were inc...

Objectives: To analyze several characteristics of patients with cerebral venous sinus thrombosis in a third level hospital and to fi nd any factors that could be related to poor progress. Materials and methods: A retrospective study was carried out of patients hospitalized from 2000 to 2014 and diagnosed with cerebral venous sinus thrombosis. Results: 55 patients with an average age of 30.2 yea...

Cerebral venous sinus thrombosis (CVST) and posterior reversible encephalopathy syndrome (PRES) are two rare diseases which may present with similar symptoms and signs. We report a case with coexisting PRES and CVST in a 34 years old postpartum female presented with multiple episodes of generalized seizures and bilateral vision loss after delivery. MRI brain and venography revealed left transve...

PURPOSE A case of bilateral papilledema secondary to cerebral venous sinus thrombosis treated with Rituximab, an anti-CD20 monoclonal antibody. METHODS A 23 year old obese female with a one week history of blurred vision, headaches and vomiting presented with bilateral papilledema. Her BCVA was 20/50 in right eye and 20/200 in the left eye with severe reduction of visual fields. Laboratory in...

Introduction: Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) was first detected in December 2019 the city of Wuhan, China, and has since taken on worldwide proportions. It is known that individuals with Coronavirus disease-19 (COVID-19) have systemic clinical manifestations. Among multisystemic effects, cerebral venous thrombosis (CVT) responsible for high mortality rates. In this...

Cerebral venous thrombosis is an uncommon condition that often has severe consequences. Symptomatic thrombosis of intracranial sinuses and veins has been mainly observed in two groups of patients: subjectswith bacterial or fungal infections, either systemic or localized to the cranium; subjects with noninfectious,miscellaneous conditions. In a substantial proportion (about 25%) of the patients ...
