No additional abnormal enhancement is seen in the left breast. RIGHT BREAST: There are innumerable T2 hyperintense non-enhancing cysts present. No abnormal enhancement is seen in the right breast.AXILLA: No abnormal lymph nodes are identified in either axillary region.
(1) 3.2 cm lobulated enhancing mass in the left breast, corresponding to the findings seen on recent diagnostic workup.
