A Case of Jugular Foramen Meningioma Mimicking Paraganglioma (Glomus Jugulare)

Abstract

Meningioma, which usually occurs in the intracranial fossa, occurs only extremely rarely in temporal bone. Tumors extending to the mesotympani are so similar that differentiating between meningioma and paraganglioma is very difficult. We report a case preoperatively diagnosed as glomus jugulare involving radical dissection, but determined postoperatively to be jugular foramen meningioma. Although the subject’s postoperative condition remains satisfactory, follow up must include collaboration with the neurosurgeon. It cannot be emphasized enough that jugular foramen meningioma must be diagnosed from characteristic radiological findings and differentiated from paraganglioma.
