Cerebral Aqueduct Stenosis

Cerebral Aqueduct Stenosis is a condition where the narrow passageway, called the cerebral aqueduct, connecting the brain’s fluid-filled spaces becomes blocked or narrowed. This blockage prevents cerebrospinal fluid (CSF) from flowing properly between the third and fourth ventricles, leading to a buildup of fluid, called hydrocephalus. This increased pressure can cause symptoms like headaches, nausea, balance issues, and vision problems. Causes may include congenital malformations, infections, or tumors. Treatment often involves surgical procedures to clear the blockage or divert the excess fluid to relieve pressure and prevent brain damage.
