Cerebral venous thrombosis (CVT) is a relatively rare condition that results from thrombosis of the superficial or deep venous sinuses of the brain. The first ever reported case of the condition was back in 1825 and this was diagnosed at autopsy. It took more than 150 years before imaging modalities were developed that could diagnose cases earlier. With the advent of CT and MR venogram, the diagnosis has become much easier and is contributing to a larger number of cases being picked up. Despite that the incidence in Western literature stays low at 1.3-1.6 cases per 100,000 people. Middle Eastern and Asian countries seem to have a larger burden of CVT, possibly because of higher rates seen with infections and pregnancies.
