Known right breast DCIS with calcifications extending to the nipple. There is heterogeneous amount of fibroglandular tissue in both breasts.Moderate parenchymal enhancement is noted bilaterally.There is extensive non-mass enhancement in the right upper outer breast extending from the posterior depth to near the nipple. This contains artifact from the two biopsy clips. Overall extent is 6.6 x 1.2 x 2.3 cm (AP x LM x CC). The abnormal enhancement extends to within approximately 1.4 cm of the nipple. In the left outer breast near the 3:00 position, a typically benign morphology focus measuring 5 mm that has a notched non-enhancing area is seen. The lesion cannot be well differentiated from background tissue on T2 images, though high signal is suggested. More likely this represents a small intramammary lymph node or a fibroadenoma.  No abnormal axillary lymph nodes are identified in either axillary region.
1. Extensive non-mass enhancement at the sites of biopsy proven DCIS measures up to 6.6 cm and extends to within 1.4 cm of the nipple.2. No enlarged axillary lymph nodes.3. Probably benign focus of enhancement in the left breast. Ultrasound correlation is recommended to look for a benign correlate such as a lymph node or fibroadenoma. If no correlative finding is seen on ultrasound, then a 6 month follow up MRI is recommended. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
