Multiple different sized cystic lesions are seen in the pancreatic head which appears not communicating with the pancreatic duct.
The common bile duct and intrahepatic bile ducts are seen grossly dilated.
The maximum transverse diameter of the CBD is 1.7 cm.
The maximum transverse diameter of the left main duct is 9.5 mm.
There is no evidence of filling defects to suggest stones.
The distal end of the CBD appears tapering and is not visualized for the last 1 cm.
The findings are suggestive of a tight stricture rather than stones.
