MRCP showed strong suspicion of a single gallbladder with a double cystic duct (Fig. 1).
ERC revealed that a normal cystic duct arose from the neck of the gallbladder, descended down and joined the common bile duct. In addition, an aberrant cystic duct arose from the cystic duct and communicated with the intrahepatic bile duct of the posterior segmental branch.

In addition, the aberrant cystic duct arose from the cystic duct and communicated with the intrahepatic bile duct of the posterior segmental branch (Fig. 2).
