title: Ascites causing a false-positive radionuclide liver image.
abstract: False-positive radionuclide liver images can occur due to impingement on the liver by adjacent normal anatomic structures or adjacent pathologic masses or fluid collections. A patient with ascites in the anterior subphrenic space had an apparent "cold" lesion in the left lobe of the liver. Ultrasonography demonstrated a normal left lobe and localized the fluid collection.
