Pituitary lesion. The T2 hyperintense and slightly hypoenhancing lesion in the left adenohypophysis appears to have increased in size, measuring up to 7 mm. The posterior pituitary, cavernous sinuses, optic apparatus, and infundibulum are intact. There are partially imaged mild scattered punctate foci of nonspecific T2 hyperintensity within the cerebral white matter. There is no abnormal intracranial enhancement.
The left pituitary lesion, which may represent a microadenoma, appears to have slightly increased in size.
