Abstract

Meningiomas are usually benign tumors that are frequently encountered in the intracranial region. They account for 15% of the overall intracranial tumors. Of the intracranial meningiomas, less than 3% extend up to the sinonasal region. The frequency of meningioma in females is 2 times higher than that in males; it is most commonly observed in the fifth decade of life. It is usually asymptomatic and detected incidentally. A small number of meningiomas may cause some symptoms including seizure attacks and cranial nerve paralysis according to their locations. On the physical examination of a 56-year-old woman, who presented with nasal obstruction, a mass that completely obliterated the left nasal passage was detected. An incisional biopsy finding of the mass revealed meningioma, and the patient was hospitalized in the clinic for surgical procedure. The mass was excised by endonasal endoscopic method. In this present article, we aimed to discuss a quite rare case, which had meningioma arising from the anterior skull base and completely obliterating the left nasal passage with the coexistence of right nasal polyp, in the light of the current literature.
