Obstructing stone is noted at the ampulla of Vater with associated dilated whole course of CBD and pancreatic duct with moderate intra-hepatic biliary radicals dilatation. The CBD joins the ventral pancreatic duct to open at the major papilla. however, the main pancreatic duct opens separately.
Uncomplicated diverticular disease of the colon is also noted.
An obstructive jaundice caused by obstructing biliary stone is commonly seen at the common bile duct. Obstructive jaundice by an ampullary lesion is commonly due to a neoplastic lesion rather than an obstructing stone. An impacted stone at Ampulla of Vater is a less common cause and it is best demonstrated by CT. This is usually associated with dilated CBD, pancreatic duct and intra-hepatic biliary radicals dilatation.
In this case pancreas divisum is also noted as a normal variant.
It is considered an emergency condition that can be complicated with suppurative cholangitis or acute pancreatitis due to complete obstruction of the biliary system.
