Abstract

Arachnoid cysts represent 1 percent of all intracranial masses. Their common locations include the middle cranial fossa, the quadrigeminal cistern, the suprasellar region, the posterior fossa, and the region of the cerebral convexities. Midline cysts often create a disturbance in intracranial dynamics due to the shift and displacement of surrounding structures, and then developed hydrocephalus. So, early diagnosis and treatment of these cysts are important. The arachnoid cyst by ultrasonogram shows characteristic well capsulated homogeneous hypoechoic cyst. We report a case of prenatally diagnosed suprasellar arachnoid cyst by ultrasonogram and MRI, which was treated postnatally.

Key Words: Suprasellar arachnoid cyst, Prenatal diagnosis, Ultrasound, MRI
