Ultrasonographic patterns of hepatobiliary mass lesions.

The study deals with an analysis of ultrasonographic (USG) patterns in 100 consecutive patients with hepatobiliary mass lesions. Amoebic liver abscess, carcinoma (CA) gall bladder and secondaries in liver comprised nearly 70% of cases. USG appearances in liver abscess, hepatoma, secondaries in liver and CA gall bladder were variable, but were characteristic in hydatid disease and congenital polycystic disease. Two patients with cholangiocarcinoma revealed dilated biliary channels with an intraluminal mass in common bile duct.
