In the presence of inferior vena cava thrombosis, the venous blood return from the lower extremity is via collateral channels to the umbilical vein and into the left portal vein. This may result in the visualization of a hot spot in the region of the liver secondary to deposition of a relatively large amount of radionuclide in the quadrate lobe when venous angioscintigraphy of the lower extremity is performed.
