====== Rathke's cleft cyst differential diagnosis ======

Cystic pituitary neuroendocrine tumors and cystic craniopharyngiomas may mimic [[Rathke's cleft cyst]]s when there is no solid enhancing component on magnetic resonance imaging (MRI).

[[Craniopharyngioma]]

no gender difference
similar age group
usually suprasellar or have a suprasellar component
tend to calcify

Rathke cleft cysts can be distinguished from pure cystic adenoma and craniopharyngioma with the presence of an intracystic nodule, T2 [[Hypointensity]], the absence of the thick contrast-enhancing wall, and absence of intralesional septations
