Cerebral venous infarction is an uncommon form of stroke, and is most commonly secondary to cerebral venous thrombosis.
Cerebral venous infarction is usually the sequelae of cerebral venous thrombosis, complicating both dural venous sinus thrombosis and deep cerebral venous thrombosis. Any other cause of venous occlusion can also lead to venous infarction, including trauma and surgical ligation.
As a result of the arterial supply to the infarcted tissue not being compromised, a haemorrhagic transformation is common and is typically heterogenous and gyriform.
