[Cancer of the breast and ultrasonographic nodule of the liver].

Metastases and angiomas are lesions which, because of their frequency, can be discovered in the liver on ultrasonographies performed on patients followed for breast cancer. This study was based on 109 patients with breast cancer and ultrasonographic nodules of the liver, generally corresponding to metastases (71 cases) or to angiomas (40 cases). The echogenicity of metastases (hypoechogenic) is so different from that of angiomas (hyperechogenic) that, in the great majority of cases, they can be distinguished on the basis of ultrasonography alone, thereby avoiding the systematic need for other complementary diagnostic investigations.
