Pituitary adenoma and TSH: surveillance. There has been interval evolution of postoperative findings related to transsphenoidal surgery, in which the sellar fat graft is no longer apparent. There is an enhancing sellar mass with suprasellar extension that measures up to 19 mm in height and 24 mm in width. The tumor exerts mild mass effect upon the overlying optic apparatus and also extends into the bilateral cavernous sinuses. The internal carotid artery flow voids are grossly intact, however. The pituitary infundibulum is intact, but deviated to the left. There is scattered paranasal sinus mucosal thickening.
