Luminal A |
MA: poorly demarcated tumor of soft texture, 25% multifocal (ILC) MI: diffuse-infiltrative growth without focal findings |
Hyperechogenic halo, spiculae |
Luminal B (incl. “HER-2 enriched”) |
MA: knotty, of firm consistency and has radial spurs MI: polygonal, cohesive tumor cells, infiltrating-destructive growth |
Increased vascularity, lack of halo |
HER-2 positive* |
MA: locally restricted, multifocal MI: presence of DCIS |
Calcifications, multifocality |
TNBC |
MA: Well-defined tumor with soft texture, focal necrosis, or hemorrhage within the tumor MI: syncytial architecture |
Lobular margins, acoustic enhancements |
