Background: Rathke's Cleft Cysts (RCCs) are unusual epithelial cysts that form in the pituitarygland from the remnants of the Rathke pouch. A fraction of these lesions expand and cause hypopituitarism, which can lead to vision loss. Furthermore, some RCCs with a high intra-cystic protein content can be confused with cystic pituitary adenoma, making differential diagnosis difficult. RCCs and pituitary adenomas are currently impossible to distinguish.
