 There is scattered fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.Right breast:In the right breast 10:00 position there is a an irregular enhancing mass with microlobulated margins showing homogeneous enhancement that measures 15 x 18 x 20 mm (AP x ML x CC). Clip artifact is identified within the center of the mass. This corresponds to biopsy-proven cancer. Located anterior to the mass is an area of non mass enhancement that measures 12 x 15 mm. Total measurement of the mass with anterior extension measures 3. 4 mm. Mild right breast skin thickening is noted.Multiple enhancing foci identified in the central right breast for which six-month follow-up MRI is recommended.At least 5 enlarged right axillary lymph nodes are identified, largest measuring 25 x 28 x 24 mm with a clip artifact within it.Left breast: A clip artifact from prior benign biopsy is identified in the left breast posterior depth at 7 o'clock position without any abnormal enhancement around it.There is an oval homogeneously enhancing mass in the left breast 3:00 position measuring 9 x 8 x 10 mm (AP x ML x CC) that needs MR directed ultrasound for further evaluation.No abnormal lymph nodes are identified in left axillary region.
