Meningiomas are common intracranial neoplasms but extracranial meningioma of the paranasal sinus is extremely rare. The recommended treatment of these meningothelial tumors is complete surgical excision. The authors report a 79-year-old woman presenting with facial pain and nasal obstruction for several months. Endoscopic nasopharyngeal examination showed a right nasal mass that arose from the nasopharynx and reached around the middle meatus. Gadolinium-enhanced magnetic resonance imaging showed a well-circumscribed nasopharyngeal mass, which originates from the right rosenmuller fossa and extends to the right nasal cavity. A biopsy was made with nasal endoscopy under local anesthesia for definitive diagnosis. Histopathologic examination was reported as benign meningothelial meningioma.
