56-year-old female with bilateral breast cancers just diagnosed: right sided mass at 10:00 position, (Grade II IDC, ER-, PR-, Her2-, Ki67 40-50%, in the setting of DCIS, coil clip placed), as well as the left breast upper inner quadrant calcifications (Grade I IDC). There is a heterogeneous amount of fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.The enhancing mass and associated clip artifact in the right breast at the 10:00 position, posterior depth, has now nearly completely resolved, now measuring 5 x 6 x 7 mm (AP X ML X CC), previously 24 x 14 x 15. The second lesion of non mass enhancement anteromedial to this mass at the 2:00 position has also decreased in size, now measuring 9 x 7 x 16 mm (AP X ML X CC), previously 19 x 15 x 22 mm.The previously identified left breast mass at the 9:00 position now measures 9 x 10 x 9 mm (AP X ML X CC), previously 14 x 12 x 18 mm. There is persistent but improved posterior, inferior, and slight anterior nonmass enhancement, the total extent of which measures approximately 31 x 19 x 14 mm (AP X ML X CC), previously 47 x 16 x 30 mm.Multiple subcentimeter nonenhancing cysts are noted in the right breast.No internal mammary lymphadenopathy is noted. Stable benign-appearing axillary lymph nodes are present bilaterally.
1.Near complete resolution of the right posterior breast mass.2.Moderate decrease in size of the left breast mass and anterior right breast lesion, as well as the associated nonmass enhancement.3.No significant axillary lymphadenopathy is evident.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
