Intestinal malrotation on barium enema

A barium enema in an adult patient (A) reveals intestinal malrotation with the cecum (asterisk) and appendix (arrowhead) on the left side in the midabdomen. The ileocecal valve is incompetent and there is a significant amount of reflux into the small bowel (squares). Diverticulosis of the sigmoid colon is present (double arrow). Image B is a normal barium enema and shows the cecum in the right lower quadrant (asterisk) and reflux of contrast into terminal ileum which lies in the right lower quadrant (squares).
