Figure 9. Extraluminal oral contrast material in a 6-year-old boy after a motor vehicle accident. CT scan shows a thin rim of high attenuation peripheral to the liver (arrows); this finding presumably represents extraluminal oral contrast material. Free fluid was seen within the pelvis, and there was slight bowel wall thickening in the lower abdomen. The bladder was intact. A perforation of the ileum was found at surgery.
