69-year-old female with left breast carcinoma status post excisional biopsy with multiple positive, on oriented margins. Assess for residual disease. There is scattered fibroglandular tissue in both breasts.Minimal parenchymal enhancement is noted bilaterally.Skin thickening is noted along the upper inner aspect of the left breast, likely postsurgical. A large seroma is appreciated within the upper inner quadrant of the left breast, approximately 9 to 10 o'clock position, extending from the cutaneous area of surgical change posteriorly to the pectoralis muscle. This seroma measures 5.8 x 2.1 x 0.9 cm and demonstrates minimal, thin peripheral rim enhancement, compatible with postsurgical change. No areas of abnormal enhancement are present in the left breast to suggest residual disease. No abnormal enhancement is seen in either breast. No abnormal lymph nodes are identified in either axillary region.
