58-year-old with known left breast DCIS with close inferior and deep margins. There is scattered fibroglandular tissue in both breasts. There are scattered high T2 signal cysts in each breast. Additionally, a 4 cm high T2 signal seroma is present in the left outer breast at the site of recent surgery.Mild parenchymal enhancement is noted bilaterally.Along the posterior slightly lateral aspect of the seroma cavity, there are 2 areas of mild nodular enhancement measuring 4 mm. Elsewhere along the seroma there is thin peripheral enhancement with no significant nodular areas. No abnormal enhancement is seen in the right breast or elsewhere in the left breast. No abnormal axillary lymph nodes are identified in either axillary region.
Mild nodular enhancement along the posterior aspect of the seroma in the left breast could represent postoperative change versus residual DCIS. No suspicious enhancement elsewhere along the seroma or in either breast.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
