47 year old woman with history of left breast DCIS s/p lumpectomy on 10/30/14. This was followed by biopsy of calcifications seen at a remote site in the inferior left breast on 11/26/14 which resulted in DCIS. There is heterogeneous amount of fibroglandular tissue in both breasts.Moderate parenchymal enhancement is noted bilaterally.Numerous signal voids representing surgical clips are seen in the central and upper left breast. The biopsy clip in the inferomedial left breast seen on the prior mammogram is not visualized on this exam. No abnormal enhancement above background is seen in either breast, specifically no suspicious enhancement is present in the inferomedial left breast. No abnormal lymph nodes are identified in either axillary region.
Post-operative changes in the left breast but no suspicious enhancing lesions on MRI to correlate to the mammographic calcifications/known DCIS. If additional breast conservation is being considered, the mammographic findings should guide localization. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
