Pituitary lesion. There is perhaps mildly heterogeneous enhancement in the pituitary gland, with apparent slightly more hypoenhancement in the right lobe. Otherwise, there is no evidence of discrete mass lesions and the pituitary gland is not enlarged or atrophic, measuring up to 6 mm in craniocaudal dimension. The pituitary stalk is situated in the midline and is not enlarged. The cavernous sinuses and optic apparatus are intact.
Possible nonspecific mildly heterogeneous enhancement in the pituitary gland, which may be related to a treated microadenoma. Otherwise, there is no evidence of discrete mass lesions and the pituitary gland is not enlarged or atrophic.
