Preoperative MRCP showed the double common bile duct. A and B coronal and axial magnetic resonance T2-weighted image showed the low signal septum in the dilated common bile duct which divided the extrahepatic bile duct into two parts, which connected to the left and the right hepatic duct respectively. C and D coronal maximum intensity projection magnetic resonance image and volume rendering image showed the dilated and duplicated common bile duct
