The common hepatic duct is seen amputated at the confluence site of both hepatic ducts being totally obstructed for a short segment. Secondary dilatation of the intra hepatic biliary radicles of both hepatic lobes is noted, much more prominent on the left lobe
Bile duct strictures are either benign or malignant.
Malignant strictures are usually short and irregular with shouldering margins, as in this case. This suggests the diagnosis of hilar cholangiocarcinoma (Klatskin tumor), but there is no pathological data available to confirm the diagnosis.
