61-year-old female with occasional headache, partial adrenal insufficiency, central hypothyroidism, and known pituitary adenoma, evaluate for interval change. The examination redemonstrates enlargement of pituitary gland in a uniform fashion which appears similar in signal intensity, morphology and pattern of enhancement since prior study. It again measures 10 x 9 mm on coronal post enhanced images and 12 x 13 mm on sagittal post enhanced images (when measured at the same locations utilized previously). There is also stable minimal thickening of the pituitary stalk however with normal pattern of enhancement since prior study. As before, the macroadenoma approaches the optic apparatus, however without abutment. There is no detectable involvement of the cavernous sinuses.
Stable pituitary macroadenoma in signal intensity, morphology, extent, and overall measurements.
