This document provides an overview of cerebral vein anatomy and pathology. It describes the external cortical veins that drain into the superior sagittal sinus and internal veins like the vein of Galen. Common pathologies involving cerebral veins include thrombosis of the superior cerebral veins which can cause seizures or bleeding. Malformations of the vein of Galen like aneurysms can cause heart failure in newborns or neurological issues in older children.
