CT Findings of Complex Small Bowel Obstruction Due to Internal Hernia Caused by Meckel's Diverticulum with Mesodiverticular Band

Abstract

Meckel's diverticulum is the most common gastrointestinal anomaly, often remaining asymptomatic but occasionally resulting in bowel obstruction. Herein, we present a case of a 6-year-old girl with an internal hernia caused by Meckel's diverticulum and mesenteric diverticular band as a rare cause of small bowel obstruction. Preoperative imaging diagnosis of this disease has been reported to be difficult. However, a detailed retrospective CT evaluation of the presented case confirmed key diagnostic findings, including identifying Meckel's diverticulum, strangulated small intestine, and findings suggesting ischemia. A meticulous CT evaluation, keeping in mind that internal hernia due to Meckel's diverticulum and mesodiverticular band is a rare cause of small bowel obstruction, is crucial. Such a detailed CT evaluation may contribute to an accurate and rapid preoperative diagnosis.
