Computed tomography of blunt trauma to the gallbladder.

The CT findings are reviewed in two patients with injuries to the gallbladder following blunt abdominal trauma. In one patient with a laceration of the cystic artery a large intraluminal clot was identified within the gallbladder associated with extensive hemoperitoneum. Another patient presented with extensive bile leakage into the peritoneal cavity 72 h after blunt trauma due to laceration of the fundus of the gallbladder. The clinical features of blunt trauma to the gallbladder and the utility of CT in this entity are reviewed.
