Figure 3. (A) Axial abdominal CT scan: C-shaped cluster of small-bowel loops (jejunum) (black arrow), posterior and lateral to sigmoid colon (white arrow), between psoas muscle (green arrow) and sigmoid colon. Displacement of the sigmoid anteromedially due to mass effect. The end of the loop segment and sigmoid vessels converge to the same point (intersigmoid fossa) (red arrow). (B) Axial abdominal CT scan: Dilated loops of proximal small bowel (green arrow) with normal distal small bowel (black arrow). Fluid collection to the peritoneal cavity, mainly in the left paracolic gutter (white arrow).
