Cholecystohepatic Duct: A Biliary Duct Variant Resulting in Postcholecystectomy Bile Leak—Case Report and Review of Normal and Common Variant Biliary Anatomy

Figure 2

(a) Frontal fluoroscopic scout image of the PCT. (b, c) Digital subtraction cholecystography (cholecystogram). (b) Filling of the gallbladder via contrast injection through the PCT demonstrates early filling of the gallbladder as well as the common bile duct (CBD) and CHD via the CD (arrowhead). An additional duct is seen extending superiorly from the gallbladder (arrow). (c) The accessory duct eventually communicates with the right posterior duct (RPD) (long arrow). Contrast also refluxes into a smaller segmental duct extending from segment VII (short arrow) and feeds into the accessory cholecystohepatic duct.
