ABSTRACT
Objective:To investigate the routine ultrasonographic findings of fibrinous breast disease lesions , and to provide the basis for the differential diagnosis of fibrocystic breast disease lesions and breast cancer.Methods:The two-dimensional ultrasonography , color doppler flow and elastography of 166 lesions in 144 patients with fibrocystic breast disease confirmed by pathology in Peking University Shenzhen Hospital from January 2015 to February 2021 were retrospectively analyzed.Results:The ultrasonographic characteristics of fibrocystic breast disease lesions were as follows: 74.1%(123/166) lesions were hypoechoic, 57.2%(95/166)lesions were irregular, 49.4%(82/166) lesions were incomplete, 90.4%(150/166) lesions were parallel, 25.9%(43/166) lesions showed small cysts, 24.1%(40/166) lesions showed coarse calcification or fine calcification, 65.1%(108/166) lesions showed no change in posterior echo, 90.4%(150/166) blood flow was poor. The elastography score of 98.2%(162/166) lesions was 2-3 points.Conclusions:The ultrasonographic features of fibrocystic breast tumor are hypoechoic, irregular shape, incomplete edge, with fine or coarse calcification, which are easy to be misdiagnosed as breast malignant tumor. However, the former is characterized by parallel growth, small cyst in the interior, no change in posterior echo, lack of blood supply and soft texture, which provide important basis for clinical differential diagnosis.
