A patient with dural sinus thrombosis had progressively worsening symptoms and signs that resolved after intradural thrombolysis. Intradural sinus pressures were 54 mm Hg. Echo-planar MR imaging revealed complex abnormalities of diffusion and widespread delay in mean transit time that improved immediately after thrombolysis. This case suggests that diffusion- and perfusion-weighted imaging can ...

BACKGROUND The purpose of this study is to demonstrate the advantages of gradient echo (GRE) sequences in the detection and characterization of cerebral venous sinus thrombosis compared to conventional magnetic resonance sequences. METHODS A total of 17 patients with cerebral venous thrombosis (CVT) were evaluated using different magnetic resonance imaging (MRI) sequences. The MRI sequences i...

Thrombosis of the straight and transverse sinuses associated with a large hemorrhagic venous infarct developed in an infant with large chronic subdural fluid collections after drainage of the subdurals. CT and MR studies obtained before and after the onset of venous sinus thrombosis showed interval widening of a segment of the posterior falx between the vein of Galen and the superior sagittal s...

Cerebral venous sinus thrombosis is a complication of the ChAdOx1 nCoV-19 vaccine that should elicit high index suspicion when patients present with persistent headache post vaccination.

Cerebral venous thrombosis is a potentially lethal disease. Early diagnosis is essential to improve its prognosis. However, its early diagnosis based on conventional imaging modalities remains a challenge in clinical settings. The purpose of this study was to evaluate whether bright sinus appearance on arterial spin-labeling perfusion-weighted image (ASL-PWI) could help identify cerebral venous...

BACKGROUND In dural venous sinus thrombosis (DVST), the mortality ranges 5-30%. Deep venous system involvement and septic dural sinus thrombosis have a higher mortality rate. In acute occlusion, collateral flow may not be established, which may result in significant edema and mass effect. Endovascular interventions may be considered as a treatment option in appropriate high-risk patients with D...

BACKGROUND Although Sjögren's syndrome has been known to complicate with white matter lesions, encephalopathy, or stroke, reports of cerebral venous sinus thrombosis due to Sjögren's syndrome with atypical antibodies are rare. CASE REPORT A 50-year-old woman was admitted to our neurological ward with nausea and vomiting following acute onset of severe headache in the left occipital region. Br...

Gadopentetate dimeglumine-enhanced MR imaging was performed in four patients with chronic dual sinus thrombosis. After injection, intense enhancement of the chronic thrombus was observed in all cases. On three-dimensional time-of-flight MR angiography, performed in one case, the occluded part of the superior sagittal sinus was not distinguishable from a normal sinus because of thrombus enhancem...

Until now, cerebral venous sinus thrombosis (CVST) was principally an autopsy diagnosis; however, with the introduction of MRI and angiography, as well as enhanced clinical attentiveness, it is now reliably diagnosed during life. Herein, we describe a case of CVST accompanied by oligodendroglioma and pregnancy. In our patient, the following factors contributed to the formation of CVST: First, t...
