Figure 1 Esophageal perforation with extraluminal fluid and pneumomediastinum (arrows) (A) tracking into the base of the neck (B). Incidental left posterior third rib fracture (red arrow) and right pectoralis muscle hematoma/edema (*) noted. This figure is available in colour online at http://carjonline.org/.

Figure 2 Severely distended stomach with intraluminal heterogeneous dense material (white arrows) and active extravasation (red arrows). No pneumoperitoneum. Contained rupture with large amount of intraluminal hemorrhage found during surgery (A-D). This figure is available in colour online at http://carjonline.org/.

Figure 3 Duodenal perforation. Thickened heterogeneously enhancing duodenal wall with extraluminal fluid (white arrows) and air (yellow arrow) on initial contrast-enhanced computed tomography (CECT) (A, B). Leaking of oral contrast and pooling around the duodenum on follow-up exam (white arrows) (C, D). This figure is available in colour online at http://carjonline.org/.

Figure 4 Mesenteric hematoma with ischemic injury to jejunum and ileum with hyperdense fluid (yellow arrows) within the mesentery and bowel wall thickening (white arrows) more prominent in areas of mesenteric hematoma (A, B). Normal appearing more distal small bowel (blue arrows). Multiple corresponding segments of bowel were found to be ischemic during exploratory laparotomy.

Figure 5 Traumatic herniation (yellow arrows) of descending colon posterior to the left lateral abdominal muscles with mildly thickened bowel wall (A, B). There is also fluid present in the herniation sac better appreciated on coronal reformats (*). This figure is available in colour online at http://carjonline.org/.
