Accessory pancreatic duct(duct of Santorini) is seen to arise from MPD in the body region. It is seen to descend down, then ascend upwards, forming a loop and finally terminating in the minor papilla. MPD is seen to drain at its conventional location at major papilla. Findings consistent with ansa pancreatica.

Contracted gall bladder with multiple tiny calculi filling the entire lumen consistent with chronic calculous cholecystitis.

The value of identifying an ansa pancreatica which is an anatomical variant of pancreatic duct lies in the fact that it predisposes to idiopathic acute pancreatitis.
