Known left breast cancer on chemotherapy There is heterogeneous amount of fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.Chemotherapy port projected over the right axillary region.Left breast:Index cancer in the left breast 12:00 position has significantly reduced in size and measures 8 x 13 x 11 mm(AP x ML X CC) previously measured 20 x 18 x 25 mm. Clip artifact noted within the mass. Very faint enhancement is identified adjacent to the clip artifact posterior and lateral to the dominant mass at the site of prior biopsy proven DCIS.Previously described oval area of nonmass enhancement at central 12:00 position measuring 6 x 9 mm is better seen is an oval heterogeneous mass that measures 6 x 4 by 5 mm, mostly unchanged. There is an oval enhancing mass measuring 6 x 5 x 4 mm at 8:00 position which is mostly unchanged, previously measured 5 x 4 mm.Total extent of the enhancing lesions measures 2.6 x 3.5 x 2.6 cm (AP X ML X CC), previously measured 5.8 cm in CC dimensionPreviously described post biopsy change along the superolateral aspect of the left breast with skin enhancement is not seen today.Right breast: No abnormal enhancement seen in the right breast.No abnormal lymph nodes are identified in either axillary region.
Significant interval reduction in the index cancer in the right breast 12:00 position and adjacent to the clip posterior and lateral to it at the site of biopsy-proven DCIS. Total extent of the enhancing mass is now measures 2.6 cm previously measured 5.8 cm in cc dimension.No abnormalities noted in the right breast or left axillary region.BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
