Cerebral venous sinus thrombosis (CVST) is a rare form of brain stroke which is often misdiagnosed. We present a case of CVST due to cerebellar tuberculous abscess. A 41-year female patient was admitted with chronic occipital headache, diminished vision, and fever. The initial brain CT scan was negative, but subsequent imaging (MRI with MRV) showed cerebellar abscess with sigmoid sinus thrombosis. Fundoscopy revealed bilateral optic atrophy. Marked improvement (subjective and objective) was noted after 4 weeks with anti-tuberculosis chemotherapy and anticoagulants. Vision loss was irreversible due to optic atrophy. The case is extremely rare due to the location, rare causative organism (tuberculosis) and complex clinical presentation (occipital headache with vision loss).
