Endoscopic transsphenoidal approach to a sphenoid sinus inverted papilloma combined with pituitary adenoma: a case...

Sphenoid sinus inverted papilloma (IP) is a very infrequent tumor, and the combination of sphenoidal IP with pituitary tumor is extremely rare. In this report, the authors describe the case of a 63-year-old male with oculomotor nerve palsy in the left eye due to sellar region tumor. After endoscopic transsphenoidal surgery, the postoperative pathological examination confirmed the co-occurrence of an sphenoidal IP and pituitary adenoma. To our knowledge, the present case is the second reported case of an IP with a pituitary adenoma.
