Fig. 1A 44-year-old woman with palpable tumor of right breast. Breast
MRI reveals cystosarcoma phyllodes of low malignancy. Dynamic T1-weighted
images before (A) and 1 (B), 2 (C), and 7 (D) min
after contrast administration show rapid enhancement with wash-out phenomenon
in late phase. Bright area in T1-weighted image (A) and dark area in
T2-weighted image (E) in lateral part of tumor near chest wall show
hemorrhage. T2-weighted image (E) shows tumor of high signal intensity
and internal cysts. Perifocal edema is visible in lateral bright adjacent
breast tissue.
