A rare case of a primary ectopic meningioma originating in the anterior ethmoid sinus is reported. The patient was a 60-year-old woman complaining of swelling of the nasal bone. A CT-scan finding demonstrated a tumor-like lesion with destruction of right anterior ethmoidal bone and the medial wall of the orbit. The patient underwent a lateral rhinotomy under general anesthesia. The tumor was surgically resected and immunohistologically diagnosed as a meningioma. There has been no recurrence for one year.
