Pituitary lesion, 3month follow. Some of the images are degraded by patient motion. There is considerable interval decrease in size of the pituitary gland, which now measures up to 5 mm in craniocaudal dimension, without residual T1 hyperintensity. There is no mass effect on the cavernous sinuses or optic apparatus. There is encephalomalacia in the right occipital lobe and left basal ganglia with hemosiderin deposition. There is diffuse cerebral volume loss and scattered patchy cerebral white matter T2 hyperintensity. There are bilateral maxillary sinus retention cysts. There is a partially imaged T2 hyperintense nodule in the left parotid gland.
1. Interval resolution of prior pituitary apoplexy, without evidence of gross sellar tumor. Otherwise, assessment is limited by the lack of intravenous contrast and motion.2. Chronic infarcts in the right occipital lobe and left basal ganglia superimposed upon chronic small vessel ischemic disease.3. Partially imaged nonspecific nodule in the left parotid gland. Dedicated parotid imaging may be useful for further evaluation.
