Female, 19 years old, with pituitary tumor, assess change in size, on bromocriptine. A hypoenhancing nodule in the left aspect of the pituitary gland has decreased in size relative to the prior exam. This lesion now measures 5 mm AP by 5 mm CC by 6 mm TV, previously 8 x 7 x 9 mm. The superior margin of the gland shows less of a bulging contour and the overall gland is relatively normal in size. The pituitary stalk enhances normally and deviates very slightly to the right but improved from prior. No significant suprasellar or cavernous sinus extension is seen.
