Bilateral Cavernous Sinus Syndrome, Pituitary Macroadenoma, and Postoperative Loss of Vision: A Case Report

Abstract

Postoperative vision loss is a rare complication. When visual loss does occur, it is rarely associated with ophthalmoplegia. We report a case of postoperative bilateral visual field deficits with concomitant complete bilateral ophthalmoplegia in a patient with a known pituitary macroadenoma after surgical excision of a small cell carcinoma of the bladder. Emergency postoperative imaging showed that the macroadenoma had increased in size and was associated with new right optic nerve edema. The patient underwent urgent excision of the macroadenoma 5 days after the onset of symptoms. Visual field deficits and associated ophthalmoplegia had completely resolved at 3-month follow-up.
