What are some cross sectional imaging features that suggest presence of bowel malrotation?
- • Malposition of the duodenojejunal junction (ligament of Treitz) from its normal location to the left of the spine at the level of the duodenal bulb
- • A predominance of small bowel loops in the right abdomen and of large bowel loops in the left abdomen
- • Inversion of the normal relationship of the superior mesenteric vein (SMV) and superior mesenteric artery (SMA). The proximal SMV is normally seen anterior to and to the right of the proximal SMA, but in the setting of bowel malrotation, the proximal SMV may instead be located anterior to and to the left of the proximal SMA
