Thrombosis of the dural sinuses and/ or cerebral veins (CVT) is a rare type of stroke and accounts for only about 0.5% of all strokes. The prevalence is only 5 per one million. It tends to occur in young adults, in the International Study of Cerebral Vein and Dural Sinus Thrombosis (ISCVT) the median age was 37 years. Outcomes in this disease are generally trend to be favorable, in the ISCVT 81% of women had complete recovery versus 71% of men. However, women without sex-specific risk factors tended to have a worse outcome than women with these risk factors. The recent reports quote a less than 10% mortality rate. Death is most often due to transtentorial herniation from cerebral edema or hemorrhagic stroke.
