title: Jugular foramen neurilemmoma mimicking an intra-axial brainstem tumor--a case report.
abstract: Jugular foramen neurilemmoma is frequently manifested as a jugular foramen syndrome or extraaxial mass. Neurilemmoma arising from the cranial nerves of the foramen, although rare, may be manifestated as an intracranial or extracranial mass lesion. When the tumor is located only in the intracranium, it is often misdiagnosed as an acoustic neurinoma or a brainstem tumor because of their similarity in clinical or radiological findings. We present a rare case of jugular foramen neurilemmoma with only intracranial extension with clinical and radiologic features of an intra-axial brainstem tumor.
