Duodenal duplication, intestinal malrotation and volvulus: An unusual cause of intestinal obstruction

Duodenal duplication cysts are unusual congenital anomalies. Both intestinal malrotation and duodenal duplication may cause extrinsic duodenal obstruction. We report a case of a 5-month-old boy who presented with signs of duodenal obstruction caused by intestinal malrotation, volvulus and a duodenal duplication cyst.
