RÉSUMÉ
Paraduodenal hernia is a type of internal hernia caused by defects in the peritoneum during fetal development. It is one of the uncommon causes of intestinal obstruction; diagnosing it and intervening promptly are required. In this case report, we describe our experience treating an adult male patient who presented with symptoms of acute small bowel obstruction and was later diagnosed with internal hernia on further evaluation. The purpose of this case report is to demonstrate the importance of imaging modalities, particularly computed tomography (CT) scan, in diagnosing these cases. Because of their mysterious symptoms, paraduodenal hernias are usually diagnosed late or incidentally. Although they are uncommon, they are far more likely to cause bowel obstruction and strangulation. Immediate surgical intervention is required following the diagnosis.
