[Left internal paraduodenal hernia: a case in a young adult]

The authors report the case of a left paraduodenal hernia which involved almost the entire small intestine in a 15 year old girl who presented with recurrence episodes of acute abdominal pain associated with König's syndrome. Radiologic examination (plain film of the abdomen and upper GI series with small bowel follow-through) was suspicious, but did not establish the diagnosis due to unfamiliarity with the radiologic appearance of the condition. The roentgenograms are shown as well as the intraoperative findings. Anatomic, pathophysiologic, clinical, and radiologic characteristics are reviewed.
