Cerebral venous sinus thrombosis (CVST) is a neuromuscular disorder with protean manifestation requiring a high index of suspicion. Early diagnosis is sometimes lifesaving. It is particularly challenging is to establish an accurate etiology as it guides the clinician for long term thrombo-prophylaxis. We report a young female with no conventional risk factors for CVST, who presented with headache, generalised seizures and prolonged loss of consciousness. Her work-up revealed an elevated serum homocysteine level which might be a possible causative association in the etiopathogenesis of this neuromuscular condition.
