CT appearance of a pelvic undescended testis secondary seminoma. a A CT plain scan showed a huge and round soft tissue mass in the pelvis, with a clear margin and inhomogeneous density. Small dots or striped calcifications and irregular low-density areas were visible in the tumor. b In the arterial phase, vascular penetration was visible in the lesion (arrow). The solid part of the tumor was slightly enhanced. c SSD reconstruction showed that a thickened and tortuous left testicular artery was the supply artery of the tumor. The testicular arteries were clearly displayed, whereas the testicular veins were poorly displayed, which was consistent with the “testicular vascular pedicle sign”. “Testicular vascular pedicle sign” means testicular arteries were clearly displayed, whereas the testicular veins were poorly displayed, and the accessory blood vessels was relatively normal developed and displayed in contrast or enhanced CT
