A rare case of primary nasoethmoidal meningioma.

Meningiomas of sinonasal tract is a rare entity especially in children. Primary sinonasal meningiomas often pose difficulty in diagnosis because of their infrequent occurrence and clinically they appear to be nasal polyp. The final diagnosis rests on the histological examination. Extra cranial meningiomas are rare in children and tend to be more aggressive. Here a case of primary ethmoid sinus meningoma with extension into the nasal cavity is presented and despite of its aggressive behavior it was benign. The importance of complete surgical extirpapion is undoubted and results in a good survival rate. Histological grading of the tumour is not crucial in predicting the rate of recurrence. The paucity of reported cases is the evidence for its rarity.
