[The value of ultrasonography in benign breast diseases].

In recent years breast scans have been widely used for the precise diagnosis of breast cancer. However, the value of this diagnostic tool is debatable in comparison to mammography in women of a childbearing age who often present a dense youthful breast. The role of clinical examination as a screening process is also examined. In the light of these findings the Authors evaluated the role played by ultrasonography in breast cancer, and in particular benign breast tumours, in a group of outpatients attending the clinic. The technique used was relatively simple: the scan in the department used for gynecological and obstetrical ultrasonography was fitted with a 5 MHz probe and was used to perform all the scans. In addition, a Kiteco space maintainer was used for ultrasonography of soft tissue. Scans were performed at a distance of 0.5 cm. The Authors examined 107 patients with benign breast tumours using ultrasonography. They evaluated the morphology, dimensions, edges and internal echo-structure of pathological formations and adjacent areas. The value of breast ultrasonography emerges from an analysis of the results both in the study of the glandular structure and in the differentiation between cystic and solid type lesions which are not always diagnosed during clinical examination. A total of 59 fibroadenoma, 44 cysts, 2 lipoma and 2 phylloids were diagnosed. Fibroadenomas had smooth edges in 98.4% of cases and were lobulate in 1.6%. In 100% of cases the fibroadenomas diagnosed presented fine internal homogeneous echoes with a lower echogenicity than that of surrounding glandular tissue.(ABSTRACT TRUNCATED AT 250 WORDS)
