[Variability of the ultrasonic picture in carcinoma of the breast].

The authors performed a retrospective analysis of ultrasonographic findings in 63 female patients with mammary cancer verified by histology. The ultrasonographic examination contributed significantly to the diagnostic results in 16.4% of patients. The ultrasonographic picture of mammary cancer was characteristically variable with the occurrence of various deviations, with prevailing main symptoms of cancer (irregularity of the shape in 81% and the contour in 100%, prevailing low and medium echoes in 97%, irregular distribution of internal echoes in 76.2%, retro-tumorous middle acoustic shade in 63.4%). The authors draw attention to the diagnostic role of individually marked deviations of echographic structure; the importance of careful examination of the formation in different planes in view of the tumour is pointed out, since the symptom of malignant process may be present in only one of them.
