Intracanalicular meningioma

South Med J. 2000 Jun;93(6):618-21.


Intracanalicular meningiomas are extremely rare and difficult to differentiate from intracanalicular vestibular schwannomas. We report an unusual case of a posterior fossa meningioma in the proximal internal auditory canal that was originally diagnosed as a vestibular schwannoma due to its appearance on magnetic resonance imaging. However, closer inspection of the preoperative neuroimages revealed features inconsistent with vestibular schwannoma that suggested the possibility of other less common lesions.
