A CASE OF PRIMARY ECTOPIC MENINGIOMA IN THE ETHMOIDAL SINUS

Abstract

A case of primary meningioma in the left anterior ethmoidal sinus is reported. Primary meningioma of the nasal cavity and paranasal sinuses is very rare. The patient is a 21-year-old woman with proptosis as the complication. There was no diplopia or other nasal symptoms. CT scan and MRI of the paranasal sinus showed a tumor localizing in the ethmoidal sinus.
The tumor was histologically diagnosed as meningioma and was surgically removed by the endonasal endoscopic approach under local anesthesia. There has been no recurrence for 9 months.
