Cerebral Venous Thrombosis: Diagnostic Accuracy of Combined, Dynamic and Static, Contrast-Enhanced 4D MR Venography

I chose this topic because the neuroimaging diagnosis of cerebral venous thrombosis (CVT) may sometimes be hard to make for patients presenting at a chronic stage of thrombosis or in the presence of associated anatomic variants of the dural venous sinuses. In particular, chronic thrombosis of dural venous sinus may resemble a true chameleon on standard MR and MRV neuroimaging, … more »

Abnormal signal intensity in dural venous sinuses on routine brain MRIs that do not contain dedicated MR venogram (MRV) sequences is a common occurrence in daily practice. Loss of flow void on T2 or high signal on FLAIR in dural venous sinuses can be due to slow flow or the presence of dural venous sinus thrombosis (DVST). Slow flow … more »

CT Density Measurement and H:H Ratio Are Useful in Diagnosing Acute Cerebral Venous Sinus Thrombosis

In an emergency setting we almost daily get a request to exclude venous sinus thrombosis. The clinical presentation is often misleading.

MR imaging obviously has advantages (e.g., it does not require radiation and has higher temporal and spatial resolutions), but it cannot always be obtained during the night or over the weekend. CT is almost always available and close to the … more »

Dural venous sinus thrombosis as a cause of intracerebral hemorrhage (ICH) is often a difficult diagnosis to make due to nonspecific presenting symptoms and complex patterns of hemorrhage and edema on CT and MRI.

Prior to our study, our standard work-up for ICH identified on noncontrast CT was … more »

Mechanical Thrombectomy in Cerebral Venous Thrombosis: Systematic Review of 185 Cases

Cerebral venous thrombosis (CVT) is a rare cause of stroke. Usual treatment includes anticoagulation, but there is a subset of patients who do not do well despite adequate anticoagulation. In those cases, CVT can rapidly progress to cause ischemic and hemorrhagic strokes, cerebral edema and mass effect, and eventually death. In the International Study on Cerebral Vein and Dural … more »

Introduction

An Update on Cerebral Venous Thrombosis

From the days of limited knowledge through the autopsy series, imaging techniques have vastly expanded our understanding of almost every aspect of cerebral venous thrombosis (CVT), including demography, pathophysiology, clinical manifestations, treatment options, and outcome. CVT is responsible for only 0.5 to 1% of stroke; however, it is well known to pose a considerable challenge to diagnosis on clinical … more »
