We report an atypical case of a 63-year-old male with the presence of seven renal arteries (RAs) (three right and four left) found incidentally on multi-detector computed tomography (MDCT) angiography which was used to investigate peripheral vascular disease of the lower limbs. Each arterial lumen was analyzed for the diameter at its origin; length and trajectory in the frontal plane (ascendant + or descendant -); and the distance between the point of origin from the abdominal aorta (AA) to its renal intraparenchymal penetration point. We also analyzed the distance between the extreme points of origin of the right and left RAs from the AA and the distance between the extreme points of penetration into the renal parenchyma of the right and left RAs. On each side, the endoluminal diameter at the origin of the main RA was significantly larger than that of the other AdRAs; however, the AdRAs were much longer than that of the main RA. From the six AdRAs, four were hilar RAs and two were superior polar RAs. Knowledge of such cases is of great clinical significance, as it may be beneficial in various urological operations or invasive arterial procedures.
