35-year-old female with right iliac fossa pain. Triphasic CT with 60ml of intravenous contrast administration. 3-D volume rendering of the arterial phase (oblique view) showing a normal right kidney (white arrow) and two left kidneys (yellow arrows) partially fused by a parenchymal bridge between them (blue arrow).

These kidneys were partially fused and demonstrated a small parenchymal bridge between them (Fig. 1).
35-year-old female with right iliac fossa pain. Triphasic CT with 60ml of intravenous contrast administration. 3-D volume rendered image in the arterial phase shows a branch from the abdominal aorta supplying the cranially placed kidney (yellow arrow) and a branch from the left common iliac artery supplying the caudally placed kidney (white arrow). Single right renal artery (red arrow) is also visible.

The caudally placed kidney received its arterial supply from a branch of the left common iliac artery (Fig. 2).
35-year-old female with right iliac fossa pain. Coronal reconstruction of contrast-enhanced CT images in the venous phase shows the three renal veins forming a common trunk and joining the inferior vena cava. The two renal veins drain the caudally placed kidney (white arrow), the renal vein drains the cranially placed kidney (red arrow) and in turn drains into the common trunk (yellow arrow) before joining the inferior vena cava. (Kvp: 120, mas: 100, 5 mm thickness, 60 ml of omnipaque intravenous contrast)

These veins in turn formed a common trunk and drained into the inferior vena cava (Fig. 3).
35-year-old female with right iliac fossa pain. 3-D volume rendering of the excretory phase (oblique view) of bilateral pelvicalyceal systems and ureters shows a normal right pelvicalyceal system and ureter (red arrow). On the left, the ureter from the cranially placed kidney (yellow arrow) passes anteriorly and joins the pelvis of the caudally placed kidney at the pelviureteric junction (white arrow) to form a single ureter.

The ureter from the cranially placed kidney passed anteriorly and joined the pelvis of the caudally placed kidney at the pelviureteric junction to form a single ureter (Fig. 4).
35-year-old female with right iliac fossa pain. Coronal reconstruction of contrast-enhanced CT images in the venous phase shows the pelvicalyceal system of the cranially located kidney facing medially. (Kvp: 120, mas: 100, 5 mm thickness, 60ml of omnipaque intravenous contrast)

The pelvicalyceal system of the kidney lying cranially was normally sited (Fig. 5).
35-year-old female with right iliac fossa pain. Coronal reconstruction of contrast-enhanced CT images in the venous phase shows the pelvicalyceal system of the caudally placed kidney facing laterally. (Kvp: 120, mas: 100, 5 mm thickness, 60 ml of omnipaque intravenous contrast)

The caudally placed kidney was malrotated, with the pelvicalyceal system facing laterally (Fig. 6).
