Biopsy proven left breast cancer. There is scattered fibroglandular tissue in both breasts. Bilateral retropectoral silicone implants are intact. Mild parenchymal enhancement is noted bilaterally.The index mass near the left 12:00 has internal artifact from the biopsy clip and measures 2.2 x 1.2 x 1.9 cm. Immediately lateral/posterior and inferior to the index mass are additional suspicious masses that appear contiguous with the index lesion in some planes. A 1:00 mass measures 0.9 x 1.0 x 1.0 cm and is probably a correlate for the mammographic asymmetry posterior to the biopsied cancer. Additional at 2:00 an additional mass measures 0.7 x 0.7 x 0.7 cm. The overall extent of these adjacent masses is 3.0 x 1.3 x 2.5 cm. A typically benign enhancing focus is seen in the left 6:00 position.No suspicious enhancement is seen in the right breast. There are two sub-centimeter enhancing foci adjacent to the implant inferiorly. These are typically benign in morphology and enhancement pattern. No abnormal lymph nodes are identified in either axillary region.
1. Left breast malignancy consisting of a 2.2 cm index lesion with adjacent satellite masses extending from the 12:00-2:00 positions. Overall extent is up to 3.0 x 1.3 x 2.5 cm.2. No suspicious axillary lymph node.3. Highly likely benign foci in the right breast. Recommend 6 month MRI follow up to ensure stability. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
