A Case of Cerebral Venous Sinus Thrombosis Followed by Subdural Hematoma in a Pregnant Woman

Cerebral venous sinus thrombosis (CVST) is an uncommon cause of stroke and accounts for 0.5-1% of all strokes. The most common clinical manifestations are intracranial hypertension and hemorrhagic infarctions [1,2]. Nontraumatic subdural hematomas can occur secondary to various types of cerebrovascular lesions, such as ruptured aneurysms [3,4] or arteriovenous malformations [3], spontaneous intracerebral hemorrhages [4], or thrombosis of a cerebral vein or dural sinus [5]. Among these lesions, subdural hematoma associated with cerebral venous thrombosis has been rarely reported. A case in which thrombosis of the left transverse sinus was followed by a frontoparietal subdural hematoma has been observed.
