case_images: Thick slab (2D) MRCP image showing duplicated extrahepatic bile ducts running parallel (arrowheads) and reuniting into a common channel (dotted arrow) at the level of the head of the pancreas consistent with type Va double common bile duct. In addition, a filling-defect suggestive of an obstructive calculus is seen in the common channel just above the ampulla (arrow). The cystic duct is inserting into the right-sided bile duct
