Rathke's cleft cyst with large frontal extension: unusual shape and pathomechanism of its formation.
The patient was a 62 year old woman who presented with a visual field defect. Magnetic resonance images showed an intra-and supra-sellar low intensity mass on T1 weighted images. The preoperative diagnosis was craniopharyngioma, Rathke's cleft cyst (RCC) or arachnoid cyst. The patient underwent transsphenoidal surgery & the pathological diagnosis was RCC. We conclude that although RCC has a round, ovoid or dumb-bell shaped configuration, it may present a unusual shape in cases with preconditions, as were seen in our patient.
