Figure 3. A 76-year-old man presented with small bowel obstruction (SBO). Contrast-enhanced CT at the right lower abdomen shows a saclike mass of unopacified dilated small bowel loops with the small bowel faeces sign (small white arrows) and mesenteric vessels converging toward its orifice (arrowhead). The "sac" is interposed between the anteromedially displaced cecum (C) with the entrance of the terminal ileum (thick white arrow) and the lateral abdominal wall. Proximal dilated opacified loops are seen. At surgery a hernia sac containing 60 cm of viable jejunum was found behind the cecum. The incarcerated bowel was reduced and the hernia orifice was sutured.
