Abstract
Ectopic pituitary adenoma is rare in clinical practice. This article reports a case of ectopic pituitary adenoma of sphenoid sinus, and summarizes the clinical characteristics, diagnosis and management. A 54-year-old female patient complaining with occasional head distension without dizziness and headache for more than 1 month was admitted due to sinus mass on conventional physical examination. Imaging examination revealed a mass in the occipital slope and bilateral sphenoid sinus. The patient underwent endoscopic resection of the mass under general anesthesia. Postoperative histopathological examination showed "pituitary neuroendocrine tumor". Postoperative recovery was good and no complications occurred. She was followed up for 2 months without relapse.
