52-year-old with history of IDC/DCIS status post lumpectomy. Tumor close to margin. Evaluate for residual disease. There is scattered fibroglandular tissue in both breasts.Minimal parenchymal enhancement is noted bilaterally.Postoperative changes in the right upper-outer breast from prior lumpectomy. There is a small residual seroma measuring 6 mm in diameter. Surrounding the cavity is a thin uniform rim of expected postoperative enhancement. In aggregate the enhancement and collection measures 10 mm in diameter. No suspicious nodular or masslike enhancement adjacent to the operative bed.Both breasts contain scattered foci of parenchymal enhancement in a symmetric distribution.Scattered borderline enlarged right axillary lymph nodes with preserved fatty hila and smooth cortices are likely reactive. No abnormality in the left axilla or internal mammary chain.
1. Postoperative changes from lumpectomy without suspicious enhancement adjacent to the seroma.2. Symmetric scattered foci of parenchymal enhancement bilaterally. Given the distribution and bilaterality this is likely benign, but short-term follow-up MRI in 6 months is recommended to this assess stability.BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
