Optic neuropathy, a warning for cerebral venous sinus thrombosis and underlying dural arteriovenous fistulae.

ABSTRACT: Cerebral venous sinus thrombosis (CVST) typically presents as headache, papilledema, and seizures. A dural arteriovenous fistula (DAVF) is a rare intracranial vascular malformation, and common symptoms include headache, pulsatile tinnitus, and stroke. The occurrence of CVST as a complication of DAVF is infrequent. Moreover, optic neuropathy presenting as the initial symptom of CVST and secondary DAVF is also unusual. We present a case of a patient with optic neuropathy and persistent intracranial hypertension who underwent head magnetic resonance imaging, which indicated CVST. She received normative anticoagulant and dehydration therapy; however, a repeated lumbar puncture showed dramatically increased intracranial pressure. Further digital subtraction angiography revealed an intracranial
