New breast cancer in the right breast. Status post two outside hospital biopsies of the right breast (10:00 pathology is mucinous IDC, 12:00 pathology is benign). MRI for extent of disease and for surgery planning. There is heterogeneous amount of fibroglandular tissue in both breasts.Moderate parenchymal enhancement is noted bilaterally.There is biopsy clip artifact in the right lateral breast at mid depth. This corresponds to the site of the recent right breast 10:00 malignant biopsy. There is a faint enhancement around the clip, though the degree of enhancement near the clip is very similar to the rest of the background breast enhancement. A definite artifact from the 12:00 benign biopsy clip cannot be seen. There is a faintly enhancing 8 mm mass at the 12:00 position that may be a correlate to the biopsied mass. This finding is benign in appearance. No abnormal enhancement is seen in the left breast. Typical benign edge parenchymal enhancement pattern is noted along the anterior/superior aspect of her breast tissue on the left.No abnormal lymph nodes are identified in either axillary region.
Right outer breast biopsy clip artifact represents the site of the recent 10:00 malignant biopsy. Only mild enhancement is seen around the clip.Faintly enhancing right breast 12:00 mass is typically benign in appearance and may correspond to the finding shown at this location on ultrasound.  BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
