Olfactory Groove Meningioma with Paranasal Sinus and Nasal Cavity Extension: A Combined Approach

A 58-year-old man had an enlarging right fronto-orbital mass. A biopsy specimen of a right nasal cavity tumor was reported as meningioma. Preoperative evaluation including skull roentgenograms, tomograms of the paranasal sinuses, brain scan, computerized axial tomography, and carotid angiography substantiated a large subfrontal mass with paranasal sinus and orbital extension.

A combined approach through a right frontal craniotomy and right lateral rhinotomy was used for a complete removal of this tumor. A review of the literature is contained herein.
