# Ileocecal Duplication Cyst Masked by Appendicitis: A Surgeon's Eternal Dilemma

## TL;DR

A rare case of an ileocecal duplication cyst in an adult was discovered during surgery for appendicitis, highlighting the difficulty in diagnosing such conditions preoperatively.

## Contribution

This case report presents an unusual adult presentation of an ileocecal duplication cyst masked by appendicitis.

## Key findings

- The patient had an asymptomatic ileal-caecal junction duplication cyst.
- The cyst was discovered during surgery for non-complicated acute appendicitis.
- Preoperative diagnosis of intra-abdominal duplications remains challenging.

## Abstract

Alimentary tract duplications are uncommon abnormalities. They are mostly found in the terminal ileum, and most develop symptoms before the age of two. Abdominal mass, intestinal blockage, intussusception, rectal hemorrhage, and abdominal pain are possible presenting signs. Intra-abdominal duplications are typically discovered during surgical examinations of the problems; preoperative diagnosis is typically challenging. Our unusual adult male patient, age 32, had an asymptomatic ileal-caecal junction duplication cyst that was linked to a non-complicated acute appendicitis.
