Emergent helical abdominal CT demonstrated a focal collection of extraluminal gas together with extraluminal fecal matter ("dirty mass") in the perirectal space (Figure 1) associated with air-fluid dilatation of some ileal loops in the pelvis (Figure 2).
CT shows also air-fluid dilatation of some ileal loops. [Powerpoint Slide]

Emergent helical abdominal CT demonstrated a focal collection of extraluminal gas together with extraluminal fecal matter ("dirty mass") in the perirectal space (Figure 1) associated with air-fluid dilatation of some ileal loops in the pelvis (Figure 2).
CT demonstrates a large amount of pneumoretroperitoneum in the presacral space.
