Quadriparesis secondary to cerebral venous sinus thrombosis: Rare cause of acute flaccid weakness

Abstract

Cerebral venous sinus thrombosis (CVST) presents with headache, seizures, focal deficits, altered consciousness and papilledema. False localising sign in the form of sixth cranial nerve palsy is commonly seen. Other cranial nerve palsies reported in CVST are oculomotor, facial, trigeminal and trochlear nerve palsies. Polyradiculopathy if seen, is in the form of reduced deep tendon reflexes (DTR), however dense quadriparesis with trunk and neck involvement and areflexia is rarely seen.
