Primary meningioma of the paranasal sinus

We report a 17 year old man with a primary ectopic meningioma in the right ethmoid and maxillary sinus. He underwent endoscopic surgery. After total removal of the tumour his subsequent clinical course was good. The clinical and pathologic features of the 32 previously reported cases in the literature are also reviewed. The pathogenesis and treatment of primary paranasal sinus meningioma is briefly discussed.
