Cerebral Venous and Dural Sinus Thrombosis

Cerebral venous and dural sinus thrombosis (CVDST) is a rare cause of stroke that accounts for only 0.5% to 1% of all strokes. Diagnosis is challenging because of the diverse spectrum of clinical presentations. Onset is usually acute or subacute, but symptoms may be subtle, and neurologic examination findings may be normal. When a stroke occurs, it is often a hemorrhagic infarct. Therefore, to make a timely diagnosis, a high degree of awareness is required when at-risk patients present with neurologic symptoms or signs.
