Hemobilia due to gallbladder contusion following blunt trauma--sonography and CT scanning for early detection: case report.

Gallbladder injury following blunt trauma is rare and early diagnosis is difficult when it is associated with other injuries. Clinical symptoms and signs alone are not necessarily helpful in diagnosing such cases. However, modern diagnostic imaging procedures such as ultrasonography and CT scanning are valuable for investigating possible gallbladder injuries. Patients with blunt trauma should be carefully examined by US and CT for early detection and treatment of gallbladder injuries.
