Uterine Intravenous Leiomyomatosis with Cardiac Extension: Radiologic Assessment with Surgical and Pathologic Correlation

Figure 1

Three-dimensional arterial phase volume-rendered CT image indicated dilation of the right uterine artery (black arrow). Several small arteries originating from the right uterine artery were considered to be tumor arteries because they extended to the IVC through the right ovarian vein and then extended into the right atrium and the right ventricle (yellow arrows). A plexus of small arteries which comprised complex vascular formations originating from the right ovarian artery (white arrow), the right subcostal artery (arrowhead), and the right uterine artery surrounded tumor arteries along the route of the right ovarian vein.
