title: Ependymal brain cyst with posterior cerebral artery infarct.
abstract: Primary intracranial ependymal cysts are congenital, benign, ependyma-lined cysts rarely seen in the pediatric age group. The authors report such a case of intracranial fronto-parietal ependymal cyst in a 3 y-old girl. Computed tomography showed a large cystic lesion which was not in communication with the ventricular system and was associated with ipsilateral posterior cerebral artery infarct and raised intracranial pressure causing midline shift. A differential diagnosis of the commoner arachnoid, hydatid or porencephalic cyst was considered. Surgical removal to decompress the brain was done; histopathology revealed an ependymal cyst. Identification of this rare pathology in the pediatric age group is emphasized with a review of the literature.
