[Modern radiology in the differential diagnosis of breast diseases accompanied by calcium micromasses].

The study was undertaken to enhance the efficiency of diagnosis of breast cancer shown up as calcium micromasses since breast diseases appear as clusters of 50-600-um calciferous inclusions that are not inclined to the formation of conglomerates without a visible node on a X-ray film, may be a manifestation of both sclerosing adenosis and nonpalpable cancer. Of the examined 4500 females aged 15 to 83 years, breast calcium masses were detected in 207. Of them, 39 females were found to have clustered calcium micromasses without a node on a X-ray film; in them cancer and sclerosing adenosis were diagnosed in 28 (71.8%) and 11 (28.2%) females, respectively. Examination was made by using clinical, mammographic, and sonographic studies. Intervention radiology and pathomorphological studies were studied. This has yielded a number of signs that are characteristic of malignant and benign diseases attended by clusters of calcium micromasses in a restricted area without a visible node on X-ray films that assist in making a correct preoperative conclusion with a greater probability in 80%.
