The pitfalls in inferior vena cavography whereby factitious findings simulate lesions are discussed. In particular, artefacts due to divergence of opaque material into normal collateral pathways, dependent layering of opaque material, streaming from tributaries, and deformities due to tortuosity or aneurysmal dilatation of the aorta are considered. The need for biplane roentgenograms is also stressed.

Suggested means to circumvent misleading findings include: (1) decubitus roentgenograms for adequate definition of dependent walls; (2) retrograde injection of the vena cava rather than antegrade injection; (3) biplane roentgenograms; and (4) delayed roentgenograms to visualize the aorta.
