Abstract
A 13-year-old boy was admitted to our hospital with a 15-day history of intermittent abdominal pain. Plain X-ray abdomen revealed evidence of intestinal obstruction with the typical mirror image of intestinal herniation. Abdominal contrast-enhanced CT demonstrated that a part of the small intestine had herniated through the posterior aspect of the descending colon. We made the diagnosis of left paraduodenal hernia with intestinal necrosis and resected a 70 cm-long necrotic segment of the small intestine. The postoperative course was favorable, and the patient was discharged from the hospital on postoperative day 14. Paraduodenal hernia shows a characteristic finding, the so-called sac-like appearance, on CT ; therefore, the possibility of this condition should be borne in mind when examining patients with a prolonged history of intermittent abdominal pain. Surgical treatment is often necessary because of incarceration.
