There is a complete fatty replacement in the pancreatic parenchyma. In the expected region of the pancreatic head, there is a multiloculated cystic structure measuring 4 x 2.5 x 2.5 cm. Some T2 hypointense cyst contents are layering posteriorly, likely to represent proteinaceous or haemorrhagic material. A further small, simple-appearing cyst is noted in the expected region of the pancreatic tail.
Additionally, two stones are in the left hepatic duct adjacent to the portal confluence. This results in mild intrahepatic biliary ductal dilatation in the left lobe of the liver, with atrophy of the left lobe likely related to chronic biliary obstruction.
