A 60-year-old woman presents with a clinical picture of intestinal obstruction. Sonographic section of the lower abdomen using a linear probe (a) showed a dilated small bowel (arrows) with thickened mucosa (M) and fluid-filled lumen (L). The arrow head shows a hyperdense echogenic line within the bowel wall indicating ischemia of the bowel. Coronal sonographic section of the right hypochondrium using a curvilinear probe (b) showed free intraperitoneal fluid in Morrison's pouch (arrow). (c) Laparotomy has revealed a gangrenous small bowel loop in the pelvis as a result of a single fibrous band
