Pituitary cyst surveillance. There is a non-enhancing well-defined mildly T1 hyperintense and T2 hypointense lesion in the midline of the pituitary gland that measures up to 8 mm, which is unchanged. There is no appreciable mass effect upon the optic apparatus or cavernous sinuses. The infundibulum is intact.
No interval change in the cystic pituitary lesion, which likely represents a Rathke cleft cyst.
