case_images: Anterior view of the right kidney and its blood vessels from Case 1. RK = Right kidney; IVC = Inferior vena cava; AA = abdominal aorta; LRV = Left renal vein; SRRV = Superior right renal vein (duplication); IRRV = Inferior right renal vein (duplication); RRA = Right renal artery; ARA = Accessory renal artery; RRP = Right renal pelvis; RU = Right ureter; RGV = Right gonadal vein; (*) point where the right gonadal vein empties into the inferior right renal vein.

case_images: In addition to these venous variations, an accessory renal artery was found emerging from the anterior aspect of the abdominal aorta just above the origin of the inferior mesenteric artery, crossing anteriorly to the inferior vena cava, and entering the right hilum of the kidney anteriorly and inferiorly to the inferior renal vein and renal pelvis (Figure 1).

case_images: Anterior view of the right kidney and its blood vessels from Case 2. RK = Right kidney; IVC = Inferior vena cava; AA = abdominal aorta; RRV = Right renal vein; RRA = Right renal artery; ARA = Accessory renal artery; IMA = Inferior mesenteric artery; RU = Right ureter; RGV = Right gonadal vein; (*) point where the right gonadal vein empties at the junction of the right renal vein and the inferior vena cava.

case_images: We also observed an accessory renal artery emerging from the anterior aspect of the abdominal aorta slightly above the origin of the inferior mesenteric artery, crossing anterior of the inferior vena cava, and entering the hilum of the kidney anteriorly and inferiorly to the right renal vein and renal pelvis (Figure 2).
