History of right mastectomy for invasive lobular carcinoma. Currently taking tamoxifen. History of bilateral breast implantation. There is scattered fibroglandular tissue in the left breast. Patient is status post right mastectomy.Minimal parenchymal enhancement is noted in the left breast. Bilateral retropectoral implants (saline on the left and silicone on the right) are again noted.No abnormal enhancement is seen in either the left breast or right chest surrounding the implants. No abnormal axillary lymph nodes are identified in either axillary region.Note is made of enhancement within and surrounding multiple left ribs. The enhancement is located at nearly the same position in the chest wall in each of the ribs, a pattern suggesting a traumatic etiology.
1. Stable findings related to previous right mastectomy and bilateral breast implantation. No MRI evidence for malignancy in the breasts. 2. Enhancement in and around left ribs in a pattern suggesting a post-traumatic etiology. Clinical correlation for any trauma to the chest wall is recommended. Correlation with a musculoskeletal rib series can be considered to evaluate the ribs for pathology such as fractures. BIRADS: 2 - Benign finding.RECOMMENDATION: ND - Routine Diagnostic Mammogram.
