Summary:

Description	Radiopaedia case ID: 86962 Image ID: 54448448 Image stack position: 26/70 Plane projection: Axial C+ Study findings: CT findings demonstrate the typical features of closed-loop obstruction in SBO. Pink arrow: proximal/afferent loop Green arrow: closed-loop (strangulated loop) Blue arrow: distal/efferent loop Red circles: Two-point of obstruction Orange arrows: a clump of bowel loops Purple star: mesenteric edema Modality: Annotated image System: Gastrointestinal Findings: CT findings show dilated loops of the small bowel with gas-fluid levels, the transitions are at two adjacent points along the course of dilated bowel (double beak sign at two sites of fusiform tapering). The bowel loops have a strange arrangement: The clump of dilated loops concentrates at the periumbilical region with the mesenteric vessels towards a central point. The wall bowel has a normal enhancement but mesenteric edema was suggestive of ischemic bowel. The whirl sign can be seen on coronal reconstruction. Intraperitoneal free fluid in the recto-vesical pouch, the left iliac fossa, and surrounding the liver.
