Natural history and surgical outcome of Rathke's cleft cysts—A study from the Swedish Pituitary Registry

Rathke's cleft cysts are benign, embryological remnants in the pituitary gland. The majority of them are small and asymptomatic but a few may become large, and cause mass effects, pituitary hormone deficiencies and visual impairment. Recommendations for the follow‐up of Rathke's cleft cysts vary since data on the natural history are sparse.
