Spontaneous Reduction of Rathke's Cleft Cysts: Report of Two Cases

Abstract

This report describes two patients with Rathke's cleft cyst in whom spontaneous reduction could be demonstrated with magnetic resonance (MR) imaging. The first patient was a 31-year-old woman and the second patient was a 17-year-old girl. Both patients complained of headache. Initial MR images revealed a cyst visualized as a ring enhancement in the sella turcica. The MR images obtained 5 weeks after the onset of symptoms revealed cyst reduction in both patients. These two cases strongly suggest the spontaneous course of Rathke's cleft cyst.
