Figure 1: Contrast enhanced CT of the abdomen and pelvis demonstrating closed loop obstruction in the right lower quadrant. (a) Axial CECT demonstrating a proximal transition point within the proximal ileum (dashed arrow) and a nearby distal transition point within the distal ileum (solid arrow). The dilated bowel loops () are anterolateral to the cecum (open arrowhead) and anterior to the ascending colon (closed arrowhead). (b) Coronal CECT image demonstrating multiple dilated small bowel loops confined to the right abdomen. Note the diminished enhancement of the dilated small bowel loops.
