Dural Venous Sinus Thrombosis Leading to Subarachnoid Hemorrhage

Dural venous sinus thrombosis (DVST) leading to subarachnoid hemorrhage (SAH) is rarely reported in the literature. A 25-year-old primigravida with a history of pre-eclampsia presented with sudden onset headache, confusion, and loss of consciousness. Examination revealed bilateral equivocal planters and bilateral papillary edema. MRI and magnetic resonance venography (MRV) showed the right sinus thrombosis with elements of SAH. The coagulation profile was unremarkable. She was commenced on low molecular weight heparin with periodic monitoring of her Glasgow Coma Scale (GCS). Her condition started improving gradually. Repeat MRI and MRV after 10 days showed resolution of thrombosis and SAH. She was discharged with follow-up, and she was doing well on her recent visit two weeks later.
