[Echotomography of malignant tumors of the liver]

The echotomographic primary liver carcinoma can be hyperechogenic and hypoechogenic, or both. In metastasis, in addition to the pattern of primary carcinoma end-lesion changes are also visible, or liver parenchyma can be diffusely heterogeneous. The echotomographic findings of primary and secondary liver tumours cannot be differentiated. The origin of metastasis in the liver cannot be established by echotomography. However, a typical echotomographic picture can be obtained in some carcinoma (colon carcinoma).
