Ms. Mitchuson is a 38 year old female with biopsy-proven malignancy of the left superior breast. Recent diagnostic workup revealed an incompletely characterized focal asymmetry seen 1.0 cm anterior to the biopsy-proven malignancy. She presents today for MR evaluation. There is heterogeneous amount of fibroglandular tissue in both breasts. Moderate background parenchymal enhancement is noted bilaterally, which limits the sensitivity of this examination.Bilateral retropectoral saline implants are identified. LEFT BREAST: In the left superior breast, mid depth, there is an irregular enhancing mass identified measuring 1.6 x 2.0 x 2.3 cm (AP x ML x SI). Susceptibility artifact from biopsy marker clip is seen centrally within this lesion, compatible with biopsy-proven malignancy. There is no additional abnormal enhancement seen in the left breast. Specifically, no abnormal enhancement is seen corresponding to the mammographically detected focal asymmetry seen anterior to the biopsy proven malignancy.RIGHT BREAST: There is no abnormal enhancement seen in the right breast.No abnormal axillary lymph nodes are identified in either axillary region.
(1) Unifocal biopsy-proven malignancy of the left superior breast. Continued surgical management is recommended at this time.(2) No abnormal MR enhancement seen to correspond to the mammographically detected focal asymmetry anterior to the biopsy proven malignancy in the left breast. No additional workup necessary at this time.(3) No MR evidence of malignancy in the right breast.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
