Rectal duplication cyst mimicking rectal prolapse: A case report

Abstract

Background: Gastrointestinal tract duplications are rare congenital malformations that are benign, presenting usually in childhood. Most common sites include the distal ileum and esophagus. Rectal presentation is quite uncommon and is usually cystic. Case Presentation: This is a case of a 3-year-old boy who came with rectal prolapse. On further examination and imaging investigations, a presacral cyst was located and a diagnosis of rectal duplication was made. The cyst was completely excised by a posterior sagittal approach. Conclusion: Rectal duplication is a rare entity that may simulate a rectal prolapse.
