Known left breast mass presents for research MRI as part of the Alan Penn study. There is scattered fibroglandular tissue in both breasts.Moderate parenchymal enhancement is noted bilaterally.In the left breast 9:00 anterior depth there is an oval enhancing mass measuring 10 x 7 x 10 mm, correlating to the sonographic finding. In the right central breast near the 6:00 position, there is an enhancing oval mass with high T2 internal signal measuring 9 x 5 x 6 mm. Differential considerations include a fibroadenoma and mucinous carcinoma. Elsewhere in each breast, there are scattered enhancing foci, none of which reach threshold for kinetic analysis. This includes in the left breast area of calcifications that will have stereotactic biopsy today. Some of the foci scattered in each breast may represent peripherally enhancing cysts. No abnormal lymph nodes are identified in either axillary region.A partially visualized high T2 signal right hepatic lobe lesion is probably benign such as a cyst or hemangioma.
1. Left retroareolar enhancing mass correlates with the sonographic finding. This will be biopsied after MRI today. No additional suspicious left breast enhancement on MRI. 2. Right breast mass for which MRI directed ultrasound is recommended. Differential considerations include fibroadenoma and mucinous carcinoma. If no correlate is seen, then MRI biopsy would be recommended. BIRADS: 4 - Suspicious Abnormality.RECOMMENDATION: T - Take Appropriate Action - No Letter.
