title: A combined neurilemmoma and angioma of the parasellar region. Case report.
abstract: A combined neurilemmoma and angioma of the parasellar region is presented that clinically simulated a pituitary tumor. The lesion produced increased intracranial pressure and subarachnoid hemorrhage (SAH). This neoplasm is believed to have originated from the leptomeninges or the perivascular neural elements, or both. The angiomatous network within the tumor could have been the source of the SAH.
