43 year old with known left breast cancer, evaluate response to therapy. There is heterogeneous amount of fibroglandular tissue in both breasts. Numerous bilateral high T2 signal cysts are seen. Mild parenchymal enhancement is noted bilaterally.The index mass in the left upper inner breast measures 3.1 x 2.7 x 2.7 cm, minimally changed compared to prior measurements of 3.2 x 3.0 x 2.7 cm. A Hydromark clip is noted from the additional benign biopsy performed further anterior to the index cancer, but there is no significant enhancement near this clip. Several enlarged left axillary lymph nodes are seen, though these are decreased in size compared to baseline. The previously measured representative node measures 1.3 x 0.9 cm, previously 1.7 x 1.3 cm. No suspicious enhancement is seen in the right breast. Many of the foci previously seen in the right breast are less enhancing now, though there is persistent enhancement of a right retroareolar focus. This may represent an inflamed cyst. No abnormal lymph nodes are identified in the right axillary region.Large hepatic mass again noted.
1. Small interval change in measurements of the left breast index mass.2. Multiple left axillary lymph nodes are decreased in size.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
