Figure 10b. Laceration of the gallbladder in a 19-year-old man after a motor vehicle collision. Axial contrast-enhanced CT scans show multiple liver lacerations (arrowheads in a) and free intraperitoneal air (*). There is noncontinuous enhancement of the gallbladder wall (arrowheads in b) with surrounding free fluid. Note the duodenal hematoma (arrow in b) and nonenhancement of the right kidney, which were the result of massive crush injury. A gallbladder laceration was confirmed at surgery, and the patient underwent cholecystectomy.
