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. © 2013 Wiley Periodicals, Inc.
