Pulmonary tumor embolism as a presenting feature of hepatocellular
carcinoma is rare. It has been reported only once previously. In that
case, other signs and symptoms of liver disease were present. We report
the case of a patient with cavoatrial hepatocellular carcinoma
presenting with isolated pulmonary tumor embolism, without any clinical
or laboratory evidence of liver disease. Hepatocellular carcinoma
should be included in the differential diagnosis as a rare cause of
pulmonary tumor embolism.
