True left-sided gallbladder with variations of bile duct and cholecystic vein

Figure 3 Drip infusion cholangiographic-computed tomography demonstrates that the cystic duct joins the extrahepatic bile duct on the right side and creates a hairpin turn anterior to the extrahepatic bile duct. One of two bile ducts of segment 2 (arrow) follows a route that is caudal to the umbilical portion of the left portal vein, that is, an infraportal course, and joins the extrahepatic bile duct; the other one (dotted arrow) follows a normal route, that is, a supraportal course.
