27-year-old woman with primary left breast angiosarcoma. a Contrast-enhanced axial CT image shows a lesion in the medial left breast with peripheral rim enhancement (arrow). b Axial T1-weighted fat-suppressed pre-contrast image shows a large mass (arrowheads) occupying much of the left medial and central left breast which displaces the normal fibroglandular tissues laterally. There is a small area of high T1 signal within the mass suggestive of haemorrhage (arrow). c Axial T1-weighted fat-suppressed early dynamic post-contrast image shows multifocal areas of variable heterogeneous peripheral enhancement (arrows). The extent of disease was underestimated on CT
