71 year-old female with pituitary adenoma status post XRT. Postoperative changes remote transphenoidal surgery. An enhancing mass in the sella extends to the medial aspect of the right cavernous sinus adjacent to the right internal carotid artery without luminal narrowing or specific evidence of cavernous sinus invasion. The mass measures 1.5 (transverse) x 1.3 (CC) x 2.0 (AP) cm (images 14 and 10, series 9 and 11) and previously measured 1.5 x 1.4 x 1.8 cm, not significantly changed from prior exams. Superiorly the mass extends into the suprasellar cistern on the right. The infundibulum is displaced to the left. The optic apparatus remains mildly deformed, with unchanged increased T2 signal abnormality within the right optic nerve. Limited images of the brain demonstrate no evidence of acute ischemia. Scattered foci of T2 signal abnormality in the periventricular and subcortical white matter likely represent chronic small vessel ischemic disease given the patient's age. Mild paranasal sinus mucosal thickening.
Right pituitary macroadenoma without significant change in size or signal characteristics compared to 12/23/14.
