## TL;DR

A rare case of an ileocecal duplication cyst causing bowel obstruction in a 56-year-old man is reported, highlighting the importance of considering this condition in adults with similar symptoms.

## Contribution

This case report adds to the limited literature on enteric duplication cysts in adults and emphasizes the need for surgical evaluation.

## Key findings

- A computed tomography scan identified a cystic mass at the ileocecal transition point.
- Pathology confirmed an enteric duplication cyst along with six incidental neuroendocrine tumors.
- Surgical resection is recommended for such cases due to potential malignancy.

## Abstract

Enteric duplication cysts are rare congenital malformations of the gastrointestinal tract, most commonly diagnosed within the first two years of life. In this report, we describe the case of a 56-year-old man who presented to the emergency department with abdominal pain and obstipation. A computed tomography scan revealed a cystic mass at the ileocecal transition point, which was concerning for malignancy. A laparoscopic right hemicolectomy was performed, and the pathology of the specimen revealed an enteric duplication cyst as well as six incidental neuroendocrine tumors. Despite their rare occurrence in adults, enteric duplication cysts should be included in the differential diagnosis of adults presenting with obstructive symptoms, and surgical resection should be strongly considered.
