Recurrence of symptomatic Rathke's cleft cyst: a case report.

A 65-year-old man presented with bitemporal hemianopsia. He had undergone frontal craniotomy for a Rathke's cleft cyst associated with narrowed visual field 8 years earlier. His vision had returned to normal soon after surgery and he remained asymptomatic until the present complaint. Neurodiagnostic imaging revealed a recurrence of the intrasellar cyst extending into the suprasellar cistern. His vision improved rapidly after a second surgery. The histological findings were the same as those of the previous operation; the cyst wall was composed of a single layer of ciliated columnar epithelium resting on a collagenous connective tissue stroma.
