Figure 16c. Intussuscepted Meckel diverticulum with infarction producing small intestinal obstruction in a 41-year-old woman with diffuse abdominal pain, nausea, and vomiting. (a) Intravenous contrast material-enhanced CT scan shows diffuse small intestinal dilatation. (b) Contrast-enhanced CT scan of the pelvis demonstrates an ileoileal intussusception, which appears as a thickened edematous segment of small bowel (arrowheads) with alternating bands of soft-tissue and fluid attenuation. There is a central focus of fat attenuation (arrow). (c) Photograph of the opened, resected surgical specimen shows an infarcted and necrotic Meckel diverticulum (arrow) that was the lead point of the intussusception.
