# Enteric Duplication Cyst Leading to a Volvulus in an Eight-Month-Old: A Case Report

## TL;DR

A rare case of an eight-month-old infant with an enteric duplication cyst causing intestinal blockage is reported, highlighting the need for quick diagnosis and surgery.

## Contribution

This case report adds to the limited literature on enteric duplication cysts causing volvulus in infants and emphasizes early intervention.

## Key findings

- An 8-month-old infant presented with bilious vomiting and was found to have an enteric duplication cyst.
- Emergency surgery confirmed a volvulus caused by the cyst and successfully corrected it.
- Early imaging and intervention prevented severe complications in this rare condition.

## Abstract

Enteric duplication cysts are rare congenital anomalies of the gastrointestinal tract. They may remain asymptomatic or present with non-specific symptoms such as vomiting, abdominal distension, and intestinal obstruction. We report the case of an eight-month-old male infant with no significant medical history who presented with a four-day history of vomiting that became bilious, accompanied by generalized hypotonia and dehydration. Clinical evaluation revealed a Glasgow Coma Scale of 11/15 and mild hyponatremia with otherwise normal laboratory results. Abdominal ultrasound showed inversion of the superior mesenteric artery and vein, raising suspicion for malrotation. Contrast-enhanced CT confirmed the "whirlpool sign" and identified a 50 mm enteric duplication cyst. Emergency surgery revealed a volvulus caused by the cyst, which was surgically corrected with successful resection. The postoperative course was uneventful. This case underscores the importance of early imaging and prompt surgical intervention in infants with bilious vomiting to prevent severe complications from rare conditions like enteric duplication cysts.
