Breast cancer staging, known right breast cancer. There is scattered fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.In the right lower inner breast at anterior depth, the known cancer measures 4.3 x 3.8 x 3.8 cm. There is additional mass like and non-mass enhancement extending laterally and anteriorly from the main mass. Total extent is 8.4 x 6.6 cm. Some of the most lateral enhancement is non-specific in appearance. There are foci near the nipple and an anterior satellite mass that measures 1.2 x 0.8 x 0.8 cm. This anterior satellite lesion and the anterior foci are all within 0.5 cm of the nipple. Skin thickening measuring 0.5 cm is noted in the medial right breast.In the left breast, a typically benign enhancing lesion correlates to the focal asymmetry seen on mammography. This measures 1.0 x 0.5 x 0.3 cm. In the short term between the outside mammograms and this study (3 months) this size appears stable. No abnormal lymph nodes are identified in either axillary region.
1. Known right breast cancer measures up to 4.3 cm. Additional mass like and non-mass like enhancement in the right breast and skin thickening, with anterior satellite lesions that approach to within 0.5 cm of the nipple. 2. Normal axillary lymph nodes. 3. In the left breast, a typically benign enhancing area measures up to 1.0 cm and correlates to the mammographic focal asymmetry. Given the typically benign appearance, and how readily visible the finding is on mammography, a 6 month mammogram follow up is recommended. If the patient had any older mammograms and the finding could be proven stable, short term follow up would not be needed.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
