BI-RADS Category (2017): 3 (probably benign)BI-RADS Category (at follow-up (2018)): 2 (benign)
Case summary:
| Postmenopausal woman presented with left breast nodule. Diagnosed as involuting (partially calcified) fibroadenoma in the left breast, BI-RADS 2 on Imaging. Survey of bilateral breast mammogram reveals grouped calcifications of suspicious morphology in the left breast on initial assessment, BI-RADS 3. Regular annual follow-up reveals stable unchanged calcifications in the left breast, diagnosed as BI-RADS 2 on imaging. |
