Unprovoked Extensive Cerebral Venous Sinus Thrombosis in a Heterozygous Prothrombin G20210A Mutation Carrier: A Rare Case Report.

Cerebral Venous Sinus Thrombosis (CVST) is a rare condition accounting for approximately 1 % of all strokes. It can occur secondary to various causes, including inherited thrombophilia, with Prothrombin G20210A mutation being the second most common. Extensive unprovoked CVST in heterozygous carriers is uncommon. This case underscores the importance of evaluating inherited thrombophilia in unprovoked CVST. Long-term, multidisciplinary follow-up is vital for managing post-thrombotic sequelae.
