Figure 7. A 43-year-old man presented with small bowel obstruction (SBO) and fever with diffuse abdominal tenderness. (a) Contrast enhanced CT at the mid-abdomen shows dilated small bowel loops and engorged and twisted mesenteric vessels (arrow) with a whirl pattern indicating volvulus. (b) More caudally, note the radial distribution of the dilated loops and convergence of engorged mesenteric vessels (arrow) suggesting a closed loop SBO. At laparotomy, viable loops were found within an internal hernia, but its distinct type could not be established. The hernia was repaired.
