Endoscopic retrograde cholangiography (ERC) in nonamebic liver abscesses.

Two cases of liver abscess are reported in whom the diagnosis was suggested by a combination of liver scanning, ultrasonography, arteriography, and liver biopsy. The diagnosis was confirmed by ERC which showed intrahepatic extravasation of contrast from the biliary tree, a characteristic of liver abscess. The value of ERC in the search for an underlying cause as well as in delineating certain features of the absceses is shown.
