Figure 5a. Complete pancreas divisum. (a) Presecretin MR image does not clearly depict the main pancreatic duct. (b) MR image obtained 5 minutes after secretin injection clearly shows the main duct in the body of the pancreas (white arrow) and the dorsal duct (arrowhead) in continuity with the main duct. Note that the main duct does not join with the distal common bile duct (black arrow), a finding that indicates complete pancreas divisum. (c) Corresponding ERCP image obtained after injection via the minor papilla helps confirm pancreas divisum and shows a santorinicele (arrow) at the minor papilla.
