Abstract

PURPOSE
We wanted to evaluate the sonographic features of adenosis tumor of the breast.
MATERIALS AND METHODS
We evaluated the sonographic findings of 9 lesions in 9 patients who had a diagnosis of adenosis tumor after excision. The mean age of the patients was 32 years. All the masses were palpable. The sonographic features were interpreted by the ACR-BI-RADS (American College of Radiology Breast Imaging Reporting and Data System). Three of the women underwent mammography.
RESULTS
The mean size of the lesion was 2.4 cm, and the shape of the masses was oval (n=9). The orientation was parallel (n=9). The margin was circumscribed (n=7), angular (n=1) and microlobulated (n=1). The lesion boundary was an abrupt interface (n=9). The echo pattern was hypoechoic (n=8) and isoechoic (n=1). Posterior acoustic enhancement was seen in 7 masses, and the other 2 masses showed combined shadowing and enhancement. The final assessment categories were classified into category 3 (n=7) and category 4 (n=2). Mammograms performed in 3 patients revealed a circumscribed mass in 2 patients and negative findings in 1 patient.
CONCLUSION
Adenosis tumor of the breast usually shows as an oval, parallel oriented, circumscribed, hypoechoic mass with posterior acoustic enhancement on sonography.
