A 70-year-old Hispanic woman presented with severe diffuse abdominal pain and distention. Associated symptoms included nausea, vomiting, and obstipation. She reported normal bowel movements prior to admission. There was no history of surgeries or hernias. On examination, she was afebrile with normal vital signs and moderate abdominal distention with tenderness. No guarding, rebound, palpable masses, or hernias were noted. A computed axial tomography (CAT) scan of the abdomen showed a segment of edematous small bowel inferior to the inguinal ligament and lateral to the bony pelvis with proximal dilatation and distal bowel collapse consistent with a high-grade obstruction. There was no free intraperitoneal gas; however, a small amount of free fluid within the pelvis was identified (Figure 1).
