The CBD is dilated with associated intrahepatic duct dilatation, particularly within the left lobe. There is abrupt cut-off of the CBD calibre at the level of the pancreatic head. There is periductal thickening and enhancement at this level which was obscured on the arterial phase imaging by motion artefact.
Further narrowing and periductal enhancement are noted at the porta hepatis. A third intrahepatic area of narrowing is seen further distally in the left liver. These 3 areas of stricturing and entire pancreas demonstrate diffusion restriction.
The pancreas appears bulky in appearance, with increased diffusion restriction.
No pancreatic duct dilatation. No focal pancreatic lesion is
identified. No peripancreatic free fluid is present.
