A Rathke's cleft cyst is a benign growth on the pituitary gland in the brain, specifically a mucin-filled [1] cyst in the posterior portion of the anterior pituitary gland. [2] [3] It occurs when the Rathke's pouch does not develop properly and ranges in size from 2 to 40 mm in diameter.
Rathke's pouch may develop benign cysts. Craniopharyngioma is a neoplasm which can arise from the epithelium within the cleft. Abnormal development of Rathke's pouch can lead to various congenital disorders such as Rathke's cleft cysts.
Craniopharyngioma is a rare, usually suprasellar [15] neoplasm, which may be cystic, that develops from nests of epithelium derived from Rathke's pouch. [16] [17] Rathke's pouch is an embryonic precursor of the anterior pituitary. [citation needed] Craniopharyngiomas are typically very slow-growing tumors.
Hemorrhage from a Rathke's cleft cyst, a remnant of Rathke's pouch that normally regresses after embryological development, may cause symptoms that are indistinguishable from pituitary apoplexy. [4] Pituitary apoplexy is regarded by some as distinct from Sheehan's syndrome , where the pituitary undergoes infarction as a result of prolonged very ...
Asymptomatic cysts, termed pseudocysts, normally require active monitoring with periodic scans for future growth. [7] Symptomatic (producing or showing symptoms) cysts may require surgical removal if they are present in areas where brain damage is unavoidable, or if they produce chronic symptoms disruptive to the quality of life of the patient.
