Known right breast cancer, presents for I-SPY 2 MRI #5. There is heterogeneous fibroglandular tissue and moderate background parenchymal enhancement noted bilaterally. Multiple simple and septated cysts are again identified in both breasts.The index mass at the 10:00 position of the right breast, posterior depth, measures 2.0 x 2.1 x 2.2 cm (AP x LR x CC, previously 2.0 x 2.1 x 2.2 cm). The right breast mass at the 12:00 position measures 0.6 x 0.7 x 0.8 cm (previously 0.6 x 0.7 x 0.7 cm). A third mass, anterior to the index mass, which does not contain a clip measures 0.9 x 1.0 x 0.8 cm (previously 0.9 x 1.1 x 0.7 cm). Other scattered enhancing foci and non-mass enhancement remain in the right breast, with total disease extent measuring 6.5 x 3.2 x 5.8 cm (previously 7.0 x 3.2 x 5.7 cm), which is without significant overall change. No abnormal enhancement is seen in the left breast. No abnormal lymph nodes are identified in either axillary region.
No significant interval change in size of known, multifocal right breast cancer.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
