A 75-year-old man developed left side ptosis and double vision. Opthalmological examination showed this to be due to disturbance of the left oculomotor nerve. The left nasal cavity was filled with a mass lesion. In computed tomography and magnetic resonance imaging, a shadow was observed in the left posterior ethmoid and sphenoid sinuses. Endoscopic sinus surgery and pathological examination revealed neurinoma. The tumor was mostly resected by a microdebritter. The postoperative course was satisfactory. The patient has recovered fully from oculomotor nerve palsy and has had no recurrence in the 21 months postoperatively.
