[Puncture aspiration biopsy under ultrasonic control in the diagnosis of breast neoplasms]

The authors studied the results of sonography of the breast and zones of regional lymph drainage in 15,973 patients. In 154 of them puncture aspiration biopsy was conducted under ultrasonic control. Breast carcinoma was found in 23 patients, in 2 of them the tumor was not palpable. The examination was performed on the Aloka-SSD-630 apparatus. The sonographic picture was that of a structure with diminished echogenic properties, irregular notched contours, and non-uniform echo signals from the internal structures. Echography with puncture biopsy made it also possible to reveal the presence of nonpalpable axillary metastatic lymph nodes and to establish the precise differential diagnosis of benign and malignant intraductal tumors. The method of puncture aspiration biopsy under control of ultrasonic examination is highly effective in the differential diagnosis of breast carcinoma.
