title: Olfactory groove meningioma with paranasal sinus and nasal cavity extension: a combined approach.
abstract: 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.
