[Hepatic echography, angiography and angiotomography: results of a combined study in hepatic tumors (author's transl)].

The authors demonstrate the interest of the association among echography, angiography and angiotomography in the diagnosis of the primitive or secondary expansive formation of the liver. The casuistry is based on 22 multiple metastases of the liver, 5 primitive tumours, 3 hepatic echinococcus, 1 abscess of the left lobe, 1 renal tumour and 1 retroperitoneal neuroblastoma with secondary hepatic localizations. The analysis of the comparison of the results among the various methods employed has shown that the identification of the lesion is (resolvable) by echography; the study of the intrahepatic vessels compromise pertains to angiography; echography, even giving significant help in judging about a possible engagement of the vena cava, necessarily needs cavography.
