D3 (retroperitoneal) segment of Duodenum is absent. Small bowel loops are predominantly on the right side of the abdomen and large bowel loops are predominantly on the left side of the abdomen. Cecum and the appendix loop are on the left lower quadrant. SMA is small and inferior to SMV.
Case Discussion
Intestinal malrotation is a congenital anomaly. It could be asymptomatic (as in this case) or predispose the patient to midgut volvulus, intestinal obstruction, and internal hernia.
It can have associations with other abdominal organ malformations such as GI tract malformations, biliary tree malformation, and pancreatic malformation.
CT scan may demonstrate:
- absence of retroperitoneal D3 segment of duodenum
- abnormal relationship between SMA (smaller and circular) and SMV
- small bowel loops predominantly on the right side and large bowel loops predominantly on the left side of the abdomen
