| Abstract |
|
Extracranial meningioma arises from ectopic arachinoidal cells and common sites of these tumors are orbit, scalp, upper respiratory tract, and parotid region. Extracranial meningioma of paranasal sinus is rare. This tumor shows various histological findings and is diagnosed by combination of CT, MRI, angiography, and pathological findings. Treatment of choice is surgical excision. Recently, we experienced a case of meningioma involving ethmoid sinus which was completely excised by endoscopic sinus surgery. So, we report our experience of ectopic meningioma of ethmoid sinus with a brief review of the literature. |
