Prolapse of Cystic Rectal Duplication : A Case Report

Abstract

An 11-year-old girl has been noted with prolapse of the rectal mucosa during defecation since the age of five. The prolapse disappeared spontaneously after defecation. On rectal examination, the mass, 5 cm in diameter, was palpated on the posterolateral wall of the rectum with an elastic consistency and it was covered with normal rectal mucosa. A barium study of the rectum showed a round defect in the posterior wall of the rectum. The mass, containing white and mucinous fluid, was resected through a transanal approach. Histological study revealed that the cyst was a rectal duplication with heterotopic cylindric ciliated epithelium and zones of cuboidal epithelium. A rare case of intestinal duplication with a ciliated epithelium is reported.
