41-year-old female with a family history of ovarian cancer and BRCA2 mutation. High risk breast cancer screening. Retropectoral saline implant appears intact bilaterally. There is heterogeneous amount of fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.New linear non-mass enhancing lesion at 12:00 position in the left breast, measuring 6 x 9 x 21 mm (AP x LR x CC).No abnormal enhancement is seen in right breast. No abnormal lymph nodes are identified in either axillary region.
1. Suspicious linear non-mass enhancement in the left breast. In view of the small amount of breast tissue and presence of saline implant, MR guided biopsy is not feasible. We recommend targeted ultrasound study, and if any sonographic correlate is found, ultrasound guided biopsy can be performed. If no sonographic correlate is detected, surgical consultation is recommended.2. No MRI evidence of malignancy in the right breast.BIRADS: 4 - Suspicious Abnormality.RECOMMENDATION: T - Take Appropriate Action - No Letter.
