Left paraduodenal hernia (LPH) is a congenital condition which develops as a result of abnormal rotation of the midgut. Generally, small intestines are wedged into the hernial sac leading to symptoms of ileus. In neglected cases, necrosis may be present and these cases may progress to fatal outcomes. In this article, we present a case of LPH which was detected on computed tomography in a patient admitted to the emergency department at our hospital with the complaints of abdominal pain who had no history of previous surgery. In laparotomy, jejunal and ileal segments which were inside the hernial sac were removed back to the abdominal cavity. The defect in the patient without any sign of necrosis was closed primarily.
