Abstract:
Objective:To explore the characteristics of color Doppler ultrasound images of breast lymphoma, and to improve the coincidence rate of ultrasound diagnosis.Methods:The color Doppler ultrasound images characteristics of 24 lesions in 21 patients with breast lymphoma in Fujian Cancer Hospital from June 2011 to January 2020 were retrospectively analyzed, and the diagnostic coincidence rate was counted.Results:All the patients were female, 18 cases were unilateral, 3 cases were bilateral. ALL cases were confirmed as primary or secondary breast lymphoma by coarse needle biopsy or surgical pathology. Pathological types included 18 cases (85.7%) of diffuse large B-cell lymphoma, 1 case of anaplastic large cell lymphoma kinase (ALK)-negative anaplastic large cell lymphoma, 1 case of Burkitt lymphoma, 1 case of Burkitt lymphoma or unclassifiable lymphoma with features intermediated between diffuse large B-cell lymphoma and Burkitt lymphoma. The maximum diameter of the lesions was (5.7±2.1) cm (range 1.4-16.0 cm), and all lesions were solid in ultrasound images; 19 lesions (79.2%) were mass-type and 5 lesions (20.8%) were diffuse. According to the characteristics of internal echo, the lesions were divided into hypoechogenicity (2 lesions, 8.3%), hyperechogenicity packed with hypoechogenicity (12 lesions, 50.0%), and hyperechogenicity interweaved with hypoechogenicity (10 lesions, 41.7%). According to Adler semi-quantitative method, the blood flow of the lesions was 3 lesions (12.5%) in grade Ⅰ, 6 lesions (25.0%) in grade Ⅱ, and 15 lesions (62.5%) in grade Ⅲ. The detection rate of lesions by color Doppler ultrasound was 100.0% (24/24), but the diagnostic coincidence rate was only 41.7% (10/24).Conclusions:Most of the breast lymphoma is diffuse large B-cell lymphoma, and the lesions can be effectively screened by color Doppler ultrasound, but the diagnostic coincidence rate is low. Most of the breast lymphoma grows in the form of mass with abundant internal blood flow signals. When the ultrasound image of the breast lesion is hyperechoic packed or interweaved with hypoechoic, the possibility of breast lymphoma should be considered.
