Normal pituitary with tiny Rathke's cleft cyst

Case contributed by A.Prof Frank Gaillard


Increased prolactin on routine blood test.

Patient Data

Age: 30 years
Gender: Male

The pituitary is normal in size, signal, and dynamic contrast enhancement. The infundibulum is midline. A tiny (1 x 3 mm) sharply circumscribed non-enhancing high T2 signal region behind the anterior pituitary presumably represents a tiny Rathke's cleft cyst. Optic chiasm, cavernous sinuses, and suprasellar region appear unremarkable. The remainder of the imaged brain (please note this study has been targeted to the pituitary, and as such the whole brain has not been imaged) appears unremarkable.

Case Discussion

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