The pituitary is normal in size and signal intensity. The infundibulum is midline.

There is a 7 x 9 mm sharply circumscribed non-enhancing high T2 signal region in the posterior portion of the anterior pituitary gland on the right side likely representing a Rathke 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 cleft cysts are common and usually are incidental asymptomatic findings.
