A case of Rathke's cleft cyst with apoplexy.

We report a case of Rathke's cleft cyst associated with cholesterin granuloma in an 8-year-old girl with apoplexy. She was admitted to our hospital in April 1996 because of repeated headache and deep ophthalmic pain, without any visual disturbance. Computed tomography (CT) of the pituitary demonstrated an intrasellar isodense mass extending to the suprasellar cistern. Magnetic resonance imaging (MRI) showed a high-intensity mass on both T1- and T2-weighted images. The preoperative diagnosis of this lesion was Rathke's cleft cyst associated with a craniopharyngioma and/or hemorrhage. Transsphenoidal microsurgery was performed, and a bloody coffee-like serous and mucinous-yellowish substance was evacuated. Curettage of the wall removed the yellowish hard mass and soft membranous tissue. Histological examination of this tumor revealed a Rathke's cleft cyst with cholesterin granuloma.
