Pituitary lesion and adenoid cystic carcinoma. There is an unchanged subcentimeter lesion within the right pituitary gland with associated foci of T2 hypointensity and no appreciable enhancement. There is no mass effect upon the optic apparatus or cavernous sinus. The infundibulum is intact. The brain and ventricular system also appear unremarkable, aside from a few nonspecific foci of cerebral white matter T2 hyperintensity. There is no evidence of acute infarction or intracranial hemorrhage. There is no evidence of perineural tumor involvement in the region of the skull base. There are partially imaged post-treatment findings in the tongue.
1. No interval change in the subcentimeter pituitary lesion, which may represent a pituitary adenoma or Rathke cleft cyst.2. No evidence of intracranial metastases.
