title: A case of gallbladder perforation detected by sonography after a blunt abdominal trauma.
abstract: Gallbladder (GB) perforation is a very rare posttraumatic abdominal injury. It is potentially life-threatening, and good outcome requires early diagnosis. We present a case of isolated posttraumatic GB perforation in which the precise sonographic (US) diagnosis led us to apply proper management. Color Doppler US showed a clear to-and-fro flow signal passing through the perforation site, and contrast-enhanced US confirmed the presence of a small defect in the GB wall. When examining posttraumatic patients, the possibility of GB perforation must be kept in mind. Color Doppler US and contrast-enhanced US are the examinations of choice to detect the perforation site and show bile movement through the perforation.
