Complete occlusion of the superior mesenteric artery by an embolus, just below its origin suggesting mesenteric vascular occlusion with failure of contrast passage distally.
Dilated small bowel loops with decreased wall thickness (paper-thin wall), no wall enhancement and multiple gas-fluid levels. Multiple gas foci are seen within the wall of dilated small bowel loops indicating pneumatosis intestinalis.
Collapsed IVC.
Mild free fluid.
