45-year-old with known left breast cancer. There is scattered fibroglandular tissue in both breasts.Marked parenchymal enhancement is noted bilaterally, with large patchy areas of marked parenchymal enhancement bilaterally, somewhat of a limitation to the study in those regions. At the site of biopsy-proven malignancy in the left breast, there is an irregularly enhancing mass with biopsy clip artifact. Correlating with the mammogram, a smaller satellite projects immediately inferior and medial to the main mass. The overall extent is 2.4 x 2.1 x 3.4 cm. No abnormal enhancement is seen in the right breast, within the limitation described above. In the left axilla, there are several lymph nodes with mildly thickened cortices. These are non-specific in appearance, with etiologies including reactive change (given the recent biopsy) and tumor involvement possible. No abnormal axillary lymph nodes are identified in the right axillary region.
1. Index lesion in the left posterior breast measures up to 3.4 cm. 2. Asymmetric, non-specific left axillary lymph nodes. Depending on planned management of the axilla, an axillary ultrasound with possible biopsy could be considered. 3. Marked background enhancement distributes in a similar pattern to her parenchyma and limits the evaluation. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
