Rathke's Cleft Cyst
- Rathke's cleft cysts (RCC) may occasionally present with symptoms of pituitary apoplexy, curiously in one small series only 2/6 had hemorrhage in the lesion at surgery so cause symptoms is uncertain.
- Intralesional nodules help make the diagnosis of RCC and are believe to be due to mucinous material on histologic examination and cholesterol and protein on biochemical analysis. It has been suggested that the nodule is a concretion of material within the cyst and that the amount of protein in intracystic nodules influences MR signal intensity.
