52 year old with biopsy proven DCIS in the left breast. Mild parenchymal enhancement is noted bilaterally.Extensive abnormal segmental enhancement is present occupying much of the left upper breast. This extends from near the pectoralis muscle to within 1.2 cm of the nipple, and includes the locations of previous malignant biopsies. The overall extent of abnormal enhancement measures 8.0 x 4.3 x 4.9 cm. No suspicious enhancement is seen in the right breast. There are a few scattered enhancing foci with typically benign kinetic patterns, including a 4 mm focus in the outer breast that may represent a normal morphology lymph node versus very small fibroadenoma. No abnormal axillary lymph nodes are identified in either axillary region.
1. Extensive enhancement in the left breast compatible with DCIS measures up to 8.0 cm. 2. No suspicious axillary adenopathy or suspicious enhancing lesion in the right breast.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
