The MR mammography of phyllodes tumors of different histological grades

Purpose: to evaluate retrospectively the MR data of breast phyllodes tumors and perform comparative analysis signs histological grade tumors. Materials methods. The analyses enrolled 27 pathologically confirmed (mean age patient 37.8 y.o.). Following features were evaluated: tumor shape structure, margins, size, type contrast enhancement, foci high signal intensity on T1-WI, hypo- or isointense T2-WI comparing with intact tissue, presence cystic inclusions their margins. Results. study included 18 benign, 4 borderline 5 malignant following showed significant correlation grade: irregular margins (p = 0.003), hypoor compared tissue 0.005). Foci T1-WI often revealed in (3/5) (2/4), but this dependence was not 0.021). According pathomorphological corresponded hemorrhages, while be necrosis. hypercellular stroma. Conclusion. Specific are useful differentiation types; furthermore mammography provides accurate for planning point biopsy.
