Axial With oral contrast
The retro mesenteric third portion of the duodenum is absent. The large bowel loops are located on the left side, and the small bowel loops are predominantly positioned on the right side, compatible with intestinal malrotation.
A 43 mm thin walled non-enhanced cyst is noted at the left adnexa.
Intestinal malrotation is a congenital anatomical anomaly, and depending on the degree of malrotation, CT may show:
- absence of a retro mesenteric (retro peritoneal) third segment of the duodenum
- abnormal SMA (smaller and more circular)/ SMV relationship
- large bowel predominantly on the left and small bowel predominantly on the right
