Primary ectopic meningioma in the right ethmoid sinus: a case report

A 29-year-old female with primary ectopic meningioma in the right ethmoid sinus was reported. She was treated by a right lateral rhinotomy with total removal of the tumor and the subsequent clinical course was good. Contrast enhanced magnetic resonance image (MRI) was most informative to define the tumor and decide the surgical procedure, in which it was demonstrated as well circumscribed mass lesion with considerable homogeneous contrast enhancement.
