​A 49-year-old woman was initially evaluated for numbness of her left arm and leg. During the workup, she was incidentally found to have a large pituitary tumor on her head MRI. The MRI brain showed a 14 mm homogeneously enhancing sellar mass consistent with a macroadenoma (Fig. 1). The mass abutted, but did not invade, the cavernous sinuses. Her labs including endocrine panels were within normal limits. Transnasal endoscopic transsphenoidal microscopic resection of the mass was performed (Fig. 2).
