A Case of Extracranial Meningioma

Abstract

Extracranial meningioma which originates in the paranasal sinuses is uncommon, and only 27 cases have been reported. A meningioma originating in the sphenoid sinus and extending to both the ethmoid sinuses and to the skull base is described and added to the literature.
The patient was a 73-year-old female who developed visual disturbance of the left eye without any other neurological signs. Plain X-ray views and CT scan of the skull showed a large tumor in the sphenoid sinus. Total removal was performed through both maxillary sinuses. There has been no recurrence (11 months since surgery), and visual acuity has improved. Histological examination revealed fibroblastic meningioma.
