Hepatocellular carcinoma with intra-atrial tumor extension identified on99mTc-labeled macroaggregated albumin single photon emission computed tomography/computed tomography.
99mTc macroaggregated albumin (MAA) scintigraphy is always performed before administration of90Y--microspheres for the treatment of liver tumors for hepatopulmonary shunt calculation. Tumor thrombus visualization in the hepatic vasculature is an infrequent finding on the99m Tc--MAA single photon emission computed tomography. We present a rare case of a hepatocellular carcinoma extending as a tumor thrombus through hepatic vein, inferior vena cava into the right atrium.
