A 46-y-old male patient with right lumbago for 1 mo. a Tortuous supply arteries were visible in the outer posterior margin of the tumor and bended into the tumor (thin arrow). The boundary of the medial margin and jejunum was unclear (thick arrow). CPR (b) and VR (c) images showed that the supply arteries originated from the abdominal aorta 2 cm below the right renal artery, which was tortuous, with no branches (arrow). The testicular arteries showed a dendritic distribution, with a branch-like shape (red arrow). The testicular arteries were clearly displayed, whereas the testicular veins were poorly displayed, which was consistent with the testicular vascular pedicle sign
