48-year-old female with left breast IDC October 20, 2015 and metastatic axillary lymph node undergoing neoadjuvant chemotherapy. Assess for response prior to surgery. Three standard views of the left breast, left CC exaggerated, and left spot MLO views were performed digitally and reviewed with the aid of R2 CAD 9.3. The breast parenchyma is heterogeneously dense, which may obscure small masses(BiRads Density Category C), unchanged in pattern and distribution. Again seen is a biopsy clip in the left upper outer breast with adjacent calcifications anteriorly and inferiorly measuring up to 15 mm in extent. The previously seen mammographic mass in this location has resolved, and no measurable mass is present currently. The left axillary biopsy clip is also partially imaged.ULTRASOUND
Favorable treatment response as described above, with no measurable residual disease in the left upper outer breast index malignancy, and significantly decreased size of previously biopsy left axillary lymph node.BIRADS: 6 - Known cancer.RECOMMENDATION: X - No Letter.
