Follow up pituitary adenoma treated with cabergoline. There is overall interval decrease in size of the pituitary tumor, particularly the suprasellar component that extends along the planum sphenoidale, which no longer displays intrinsic T1 hyperintensity related to prior hemorrhage. Indeed, the tumor measures up to 27 mm in the craniocaudal dimension, previously 37 mm. There is consequently decreased massa effect upon the right gyrus rectus and optic apparatus. There is mild volume loss in the anterior gyrus rectus, perhaps related to chronic ischemia from mass effect. There is persistent extension of tumor in the bilateral cavernous sinuses, left greater than right, with encasement of the left cavernous internal carotid artery. The infundibulum is deviated to the right.
Interval decrease in size of the pituitary macroadenoma, particularly the suprasellar component.
