case_images: The CT scan shows, in axial (a) and coronal (b) sections, the colon on the left side of the abdomen (white star), and the small intestine on the right side (arrowhead).

case_images: The findings disclosed a configuration in which the entire length of the small bowel, inclusive of the duodenojejunal juncture, assumed a position to the right of the spinal column, while the entire colon aligned to the left (Figures 1a, 1b).
case_images: CT images demonstrating (a) the absence of the third portion of the duodenum in the aorto-mesenteric clamp and (b) the abnormal superior mesenteric artery-superior mesenteric vein (SMA-SMV) relationship associated with intestinal malrotation, with the SMV (arrowhead) being to the left of the SMA (full arrow).

case_images: Notably, there was an absence of a third portion of the duodenum within the aorto-mesenteric clamp setup (Figure 2a). Additionally, there was an inversion in the customary anatomical relationship of the superior mesenteric vessels, as evidenced by the vein traversing to the left of the artery (Figure 2b).
case_images: Axial section (a) of an aplastic uncinate process. No pancreatic tissue is visible behind the superior mesenteric vein. (b) For clarification, the pancreas with its globular head is marked in blue, highlighting the aplasia of the uncinate process.
