Figure 4

This figure shows an example of an aortic angiosarcoma of the distal aortic arch in a 71-year-old male patient who was treated for congestive heart failure. The MDCT and MRI images (A-D) nicely illustrate the typical pedunculated appearance of the lesion in a location that is atypical for atheromatous thrombi. The first pass perfusion sequence (F) suggests vascularisation of the lesion as compared to the unenhanced control acquisition (E, circle).
