A Case of Primary Extracranial Meningioma in the Ethmoid Sinus

Abstract

Meningioma is a well recognized tumor of the central nervous system, but primary extracranial meningioma in the paranasal sinus and nasal cavity is very rare. Clinical characteristics of meningioma do not confirm to those of extracranial meningioma, hence they can present diagnostic challenges. We have experienced a case of primary ethmoid meningioma. The patient was treated by a left lateral rhinotomy with total removal of the tumor. Histopathologic examination confirmed the diagnosis of meningioma. A follow-up after 15 months revealed no evidence of recurrence.
