69 year old female with known left IDC and right DCIS for MR study. There is heterogeneous amount of fibroglandular tissue in both breasts.Moderate parenchymal enhancement is noted bilaterally.RIGHT BREAST:There is regional non-mass enhancement at 2:00 - 4:00 position, measuring 30 x 35 x 16 mm (AP x LR x CC), corresponding to the area of malignant calcifications. Medial and inferior to the non-mass enhancement, there is a 6 x 6 x 6 mm enhancing mass, likely corresponding to the focal asymmetry on mammogram. There is an additional linear non-mass enhancement measuring 9 mm in AP direction, located posteriorly from the small mass. Overall size of all these abnormal findings is 47 x 35 x 16 mm.LEFT BREAST:There is a rim-enhancing mass, measuring 17 x 14 x 16 mm, at 2:00 position, with a marker clip. This is a proven IDC.AXILLAE:No abnormal lymph nodes are identified in either axillary region.
