Follow up of a pituitary lesion. There is a mildly hypoenhancing lesion in the left pituitary gland that measures up to 10 mm. There is no mass effect upon the optic apparatus or cavernous sinus. There is slight deviation of the pituitary infundibulum to the right. The cavernous carotid artery flow voids are intact.
An unchanged lesion in the left pituitary gland that measures up to 10 mm likely represents an adenoma.
