The pituitary is normal in size and signal intensity. The infundibulum is midline.
There is a 5*7 mm sharply circumscribed non-enhancing high T2 signal region in the anterior pituitary presumably represents a Rathke's cleft cyst. There is a central T2 hypointense nodule (dot sign).
Optic chiasm, cavernous sinuses, and suprasellar region appear unremarkable.
The remainder of the imaged brain appears unremarkable.

Small Rathke's clefts cysts are common and usually are incidental asymptomatic findings.
