Pituitary adenoma status post surgery: surveillance. There has been interval evolution of postoperative findings related to transsphenoidal surgery for debulking of a pituitary macroadenoma. There is ano significant interval change in size of the mass that measures up to approximately 25 mm centered in the left sella with extension into the left cavernous sinus with partial encasement of the left internal carotid artery, which is not significantly changed. There also appears to be invasion of the left clivus and persistent enhancement within the bone marrow of the right planum sphenoidale. There is high T2 signal and perhaps mild volume loss of the optic chiasm. However, there is no discernible mass effect upon the optic apparatus by the pituitary mass. There are secretions and mucosal thickening within the sphenoid sinuses. There are multiple nasopharyngeal mucus rentention cysts.
