Rathke’s cleft cyst mimicking cystic craniopharyngioma: Surgical experience of endoscopic endonasal approach

Rathke’s cleft cysts (RCCs) are non-neoplastic cysts originating from Rathke’s pouch remnants. This case report presents a unique case of a suprasellar RCC that closely resembles craniopharyngioma, highlighting the diagnostic difficulty involved. A 51-year-old female patient presented with headaches and visual disturbances, and magnetic resonance imaging revealed two cystic masses around the pituitary stalk. Initially suspected as craniopharyngioma, surgical intervention revealed RCC based on histopathological examination. The report emphasizes the importance of differentiating RCC from other parasellar cystic masses, especially craniopharyngioma, and discussing key diagnostic factors.
