title: An ependymal cyst in cerebello-pontine angle presenting with syncope.
abstract: Intracranial ependymal cysts are rare, congenital, benign lesions. These commonly occur in the supratentorial regions and usually generate no symptoms. The cerebellopontine angle (CPA) is an extremely rare site for ependymal cysts. Furthermore, there are no previous reports of CPA ependymal cysts related to syncope. We report a case of ependymal cyst in the left CPA with syncope. The patient underwent a cardiologic evaluation for syncope after admission, but there were no definite cardiologic abnormal findings. He underwent fenestration into the subarachnoid space, and the pathologic diagnosis revealed an ependymal cyst. We analyzed this case with review of other literatures.
