A Case of the Suprasellar Arachnoid Cyst

ABSTRACT

We report a case of the suprasellar arachnoid cyst with hydrocephalus which was incidental finding after minor head injury. Preoperatively, we studied the CT cisternography through lumbar route with niopam. It revealed that the arachnoid cyst was communicated with ventricles and delayed filling and clearance pattern of the cyst. The suprasellar arachnoid cyst with hydrocephalus was treated by combined craniotomy with partial removal of the membrane wall and cystoperioneal shunt. We reviewed the literature and discussed the diagnosis and treatment of the suprasellar arachnoid cyst.
