Abstract
We presented a quite rare case of non-Hodgkin's lymphoma with cardiac metastasis which was demonstrated and confirmed by radionuclide studies and autopsy. A 57-year-old male with Superior Vena Cava syndrome underwent radionuclide angiography using 99mTc-HSA prior to 67Ga-citrate and 201Tl-chloride studies for suspected right atrial metastasis from non-Hodgkin's lymphoma. The radionuclide angiography revealed a filling defect in the right atrium. 67Ga and 201Tl studies showed increased accumulation of both nuclides in the right atrium, in congruence with the region showing a filling defect by the radionuclide angiography. These result suggests that radionuclide study might be useful in detecting metastatic tumor in the heart. And general condition was improved by radiation to the heart.
