Brain MRI on 2/26/16 showed an incidental 4 mm wide T1 hyperintense nodule superior to the pituitary gland. There is redemonstration of a small T1 hyperintense focus posterior and superior to the pituitary gland, alongside the neurohypophysis. The pituitary infundibulum is intact. The anterior pituitary gland is unremarkable. The optic apparatus and cavernous sinuses are unremarkable.
Redemonstration of a small T1 hyperintense focus posterior and superior to the pituitary gland may represent a prominent dorsum sella versus less likely a Rathke cleft cyst.
