Ms. Pedrido is a 50-year-old female with newly diagnosed left breast cancer (IDC, grade 2, mucinous type). She presents for MRI imaging evaluation. There is heterogeneous amount of fibroglandular tissue in both breasts. Mild background parenchymal enhancement is noted bilaterally.In the left medial breast, there is an irregular enhancing mass identified measuring 2.8 x 2.0 x 1.9 cm (AP x ML x SI). This mass demonstrates increased T2 signal intensity, characteristic for mucinous carcinoma. Two biopsy marker clips are seen, one of which is centrally located (ribbon clip) and one of which is located antero-medial to the mass (hydromark clip). Associated post-biopsy changes are seen, including minor skin thickening/enhancement at biopsy entry site. There is no abnormal enhancement identified in the right breast. There are numerous cysts of varying T2 signal intensity identified bilaterally.No abnormal axillary lymph nodes are identified in either axillary region.Few subcentimeter T2 hyperintense cysts are identified in the liver.
(1) Unifocal malignancy of the left breast. If breast conservation therapy is desired, the ribbon clip can be used for preoperative localization. (2) No MR evidence of malignancy of the right breast. BIRADS: 6 - Known cancer.RECOMMENDATION: X - No Letter.
