title: Primary schwannoma of the petrous apex.
abstract: We present two patients with primary petrous apex schwannoma. These tumors were centered on the petrous carotid artery and are thought to have originated from the deep petrosal nerve. This would account for the paucity of neurologic deficits in these patients. Imaging findings and surgical treatment of primary petrous apex schwannomas are discussed.
