Coronal reformatted image of multidetector computed tomography using split-bolus technique shows partially duplicated infrarenal inferior vena cava rejoining before vena caval bifurcation (a). The contrast opacified midureter is passing through a slit-like opening between the duplicated inferior vena cava (black arrow) with dilatation of the proximal ureter and pelvicalyceal system (b). Left kidney is ectopic and malrotated (a and b)

CT scan revealed splitting of infrarenal IVC into two parts and rejoining inferiorly after a length of 4.2 cm [Figure 1]. The midureter is coursing posterior to the IVC and passing between the split segment of IVC causing narrowing of the ureter [Figures 1 and 2].
Sagittal oblique reformatted image (a) and axial images (b and c) in delayed phase computed tomography scan shows the ureter (white arrowhead) crossing the duplicated inferior vena cava (white arrow) from dorsal to ventral
