The case of a 28-year-old female patient with portal vein thrombosis m
imicking tumour and causing obstructive jaundice is presented. The cav
ernous-transformed enlarged portal vein, explaining the mass-like lesi
on in the hepatic hilum on ultrasonography, compressed the extrahepati
c bile ducts and caused obstructive jaundice. Endoscopic retrograde ch
olangiography demonstrated multiple nodular extrinsic indentations of
the extrahepatic bile ducts with moderately dilated intrahepatic bile
ducts.
