Case Report: Delineated Radiocolloid Hepatic “Hot Spot” With Superior Vena Caval Obstruction

Abstract

When imaging the liver in the presence of superior vena caval obstruction, a region of increased radiocolloid uptake may occur in the area of the porta hepatis. Recently, this was demonstrated with a 32-year-old male patient. With advances in electronic spatial resolution, however, the imaged “hot” area is now considerably better delineated. This artifact within the liver in the presence of superior vena caval obstruction is thought to be due to collateral intrahepatic circulation in the liver’s caudate lobe.
