title: [Ultrasonography and computerized tomography in the diagnosis of gallbladder carcinoma].
abstract: The US and CT images of 40 surgical patients with histologically proved gallbladder carcinoma were retrospectively reviewed. The radiologic diagnosis was correct in 22 patients (55%). Gallbladder carcinoma patterns were: an intraluminal mass (type I) (7 patients, 17.5%), focal or diffuse wall thickening (type II) (5 patients, 12.5%) a mass replacing the gallbladder (type III) (10 patients, 25%). In 5 patients with type I or II gallbladder carcinoma, US and CT diagnosis was made easier by the presence of associated findings--i.e., liver infiltration and/or metastases, lymphadenopathy, dilated intrahepatic ducts, ascites. In 7 patients a gallbladder carcinoma was suspected in the presence of a small intraluminal mass (6 cases) or of focal wall thickening (1 case), with no stones and with dilated intrahepatic biliary ducts. In the extant 18 patients (45%) the radiologic diagnosis was: polyps (6 cases), stones with cholecystitis (11 cases) and empyema (1 case). US is the examination of choice in the diagnosis of gallbladder and biliary ducts conditions, but several diagnostic problems may arise in the differentiation from polyps and acute inflammatory disease. CT better demonstrates gastrointestinal tract invasion and lymphadenopathy, which can be a valuable finding for treatment planning.
