title: Supratentorial neuroepithelial cysts. Report of two cases.
abstract: The paper reports two cases of supratentorial neuroepithelial cysts, also called ependymal cysts. One of them was extracerebral and the other intracerebral. The preoperative diagnosis was made by determination of attenuation values of consecutive sections of cyst on computed tomography. The ultrastructure of the cyst wall was studied in one case. Other problems dealing with these rare lesions are discussed.
