Intracranial glossopharyngeal schwannoma, a tumour imitating an acoustic schwannoma.
Neurinomas originating from the ninth cranial nerve are rarely observed. The early signs and symptoms of a glossopharyngeal neurinoma are rather discrete, and it can happen that a tumour here will often first be recognised with the signs and symptoms of an expanding posterior fossa lesion--thus often closely resembling an acousticus neurinoma.
