Two cases with the accessory bile duct regarded as a caudate lobe bile duct. A: This view shows a patient's inferior right-side 3D image. The connection of the accessory bile duct from the caudate lobe to the intrapancreatic bile duct (black dashed arrow) was easily recognizable. The cystic duct (black arrow) branched from the middle bile duct. B: This view shows a patient's superior left-side 3D image. The connection of the accessory bile duct from the caudate lobe to the middle bile duct (black dashed arrow) was easily recognizable. The cystic duct (black arrow) branched from the middle bile duct.
