Spontaneous Intracranial Hypotension as a Cause of Subdural Hematoma in a Patient with Cerebral Venous Thrombosis on Anticoagulation Treatment

摘要

Spontaneous intracranial hypotension (SIH) has recently been reported to be an additional risk factor for cerebral venous thrombosis (CVT).1,2 The existence of SIH also increases the risk of developing subdural hematoma (SDH) due to brain sagging and subdural fluid collection with fragile and dilated new dural vessels.1,3 However, the occurrence of SIH in patients with CVT followed by SDH is rare, and it challenges treatment decision-making by clinicians. Here we report a CVT patient with SIH who developed SDH, which are both known complications of SIH.
