53 year-old male with pituitary macroadenoma, assess for interval change. Redemonstrated is a well demarcated mass in the pituitary gland with the high signal intensity on T1 and mixed signal intensity on T2 which occupies a majority of the pituitary gland. This interval decrease in size in the mass, now measuring 15 mm transverse by 9 mm craniocaudal by 10 mm AP (previously 16 mm transverse x 13 mm craniocaudal x 13 m AP). Concurrent with this decrease in size, slight bulging of the gland superiorly is no longer evident, and there is less anterior displacement of the pituitary stalk. As before, there is no evidence of any contact or mass effect upon the visual complex. There are normal bilateral cavernous sinuses and internal carotid arteries as well as Meckel's caves.
