We report a case of preoperatively diagnosed right paraduodenal hernia. A 71-year-old man with malignant lymphoma undergoing chemotherapy reported sudden right mid-abdominal pain. Small bowel series showed a jejunal loop with stenosis of inlet and outlet in the right mid-abdomen. CT scan of the upper abdomen showed an encapsulated and dilated small bowel loop in the right mid-abdomen, diagnosed as right paraduodenal hernia. In surgery, the hernial orifice was located in the intermesocolic fossa of Broesike. The incarcerated small intestine was repositioned and defect of transverse mesocolon was closed by suture. The superior mesenteric artery and vein were not located in the anterior wall of the hernial sac. This finding differed from the common type of right paraduodenal hernia in the mesentericoparietal fossa of Waldeyer.
