Right-sided paraduodenal hernia: rare cause of recurrent abdominal pain.

Right-sided paraduodenal hernia (PH) is a rare congenital malformation that arises due to a defect in the rotation of the middle intestine during embryogenesis. Though it is usually an incidental finding on autopsy or during laparotomy, it can be responsible for episodes of recurring abdominal pain or even acute abdomen (1,2). A search of the literature only revealed three cases of rightsided PH diagnosed by computed tomography (CT) (3-5).
