title: "Hot spot" on liver scan produced by inferior vena caval obstruction.
abstract: A patient suspected of having an obstruction to the inferior vena cava developed a "hot spot" in the liver when an inferior vena cavogram was performed with Tc-99-sulfur colloid. The "hot spot" was demonstrated to be the result of the collateral circulation.
