title: Visual loss in a 42-year-old man.
abstract: A 42-year-old man developed blurred vision and was found to have a right, incongruous, inferior homonymous quadrantanopia. Neuroimaging disclosed a suprasellar mass. The mass was thought to be a pituitary adenoma that was compressing the left optic tract, and transsphenoidal surgery was planned; however, because the defect was primarily inferior, indicating damage to the superior aspect of the optic tract, it was recommended that a craniotomy be performed. The mass was found at surgery to be a craniopharyngioma.
