Abstract
Purpose
To report a rare case of a patient with diplopia due to a mass in the sphenoidal sinus, histologically diagnosed as carcinoma.
Case summary
A 57-year-old male visited our clinic complaining of diplopia and ptosis for 10 days. He had esotropia 45 prism diopters in the primary position, markedly limited abduction, and a 4 mm dilated pupil in the right eye compared with a 2 mm pupil in the left eye. Enhanced magnetic resonance imaging revealed a sphenoidal sinus mass extended into the pituitary gland and sella turcica with homogeneous intense enhancement. Metastatic workups, including CT of the head, neck, chest, and abdomen were unremarkable. He underwent a transsphenoidal approach mass debulking surgery followed by radiotherapy for 6 weeks. Histological findings were compatible with carcinoma. Six weeks after radiotherapy he had esotropia of 20 prism diopters in the primary position. Abduction limitation was partially recovered postoperatively.
