Abstract : An infrarenal duplication of the inferior vena cava with both channels lying on the right side of the aorta was fortuitously found during an abdominal Computed Tomography performed on a 52 year-old woman. Only two same cases seem to be reported in the literature. This very uncommon abnormality probably results from persistence of the infra-renal part of the right subcardinal vein. Radiologists have to be aware of this right-sided ipsilateral duplication for it may be a trap in abdominal imaging as well as "classical" inferior vena cava duplication located on both sides of the abdominal aorta.
