Thin-slice CT findings of biliary stricture due to blunt abdominal trauma: reports of three cases

Thin-slice CT findings were reviewed in three patients with biliary stricture due to blunt abdominal trauma. In all cases, the stricture was located at the suprapancreatic portion of the common bile duct. Central enhancement with a low attenuation rim at the bile duct between the stricture and the papilla of Vater was apparent in all cases. Ancillary findings such as focal renal laceration (1 case) and left rib fracture (1 case) were also seen. These CT findings may help in the diagnosis of biliary injury for patients with blunt abdominal trauma.
