Lymphomatous involvement of intrahepatic and extrahepatic biliary ducts. PTC and ERCP findings

The intra- and extrahepatic biliary ducts were examined by endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography in 10 patients with malignant lymphoma and suggested hepatic involvement. Different radiologic appearances of the biliary tract are described, related to lymphomatous involvement of the liver or extrahepatic tissues, and compared with laparoscopic findings and final diagnosis. The results demonstrate the accuracy of cholangiography by PTC and ERCP and its usefulness in patients in whom non-invasive techniques fail to provide a reliable diagnosis.
