Personal history of left breast invasive ductal carcinoma status post chemotherapy, lumpectomy, radiation therapy and sentinel node biopsy. There is heterogeneous amount of fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.There is a new 1.3 cm area of linear non-mass enhancement in the central 3:00 position of the left breast. No abnormal enhancement is seen in elsewhere in the left breast or in the right breast. Mild non-suspicious enhancement is present at the left breast lumpectomy bed, with no nodular enhancing component present here. There are scattered enhancing foci bilaterally, some of which are small inflamed cysts, a finding that has been seen on prior MRIs for this patient. No abnormal axillary lymph nodes are identified in either axillary region.
New left breast linear non-mass enhancement is present. Given the appearance, MRI guided biopsy is recommended. Degree of suspicion is relatively low, and a benign diagnosis from biopsy would be accepted. BIRADS: 4 - Suspicious Abnormality.RECOMMENDATION: H - Percutaneous Biopsy/Aspiration.
