Intracerebral cyst due to ectopic choroid plexus: case report.

A case of supratentorial intracerebral cyst, containing ectopic plexus, is discussed. The cyst had no communication with the ventricular system or subarachnoid space. The cyst wall was lined in part by flattened or cuboidal epithelium and in part by glia. Fronds of choroid plexus protruded into the cavity of the cyst in one part. The preoperative and postoperative computerized tomography scans are presented and the operative findings are discussed. The management of such cases is reviewed.
