Intracerebral Schwannoma Mimicking Meningioma: Case Report

Abstract

Intracranial schwannomas account for 8% of all primary brain tumors, approximately 80-90% of them being seen in the cerebellopontine angle in relation to the vestibular nerve. Schwannomas arising within brain parenchyma, unrelated to the cranial nerves, are extremely rare. To our knowledge, only 73 cases of intracerebral schwannoma have been described in the English-language literature so far,1-5 but only six cases of intracerebral schwannoma mimicking meningioma have been reported1-3 and there have been few reports regarding neuroradiological findings. Disagreement remains concerning the histogenesis of these tumors.
