title: Multiple scintigraphic findings in a patient with a primary myocardial sarcoma.
abstract: Primary myocardial sarcomas are rare. We report the scintigraphic findings observed with TI-201, Ga-67, Tc-99m pyrophosphate, and Tc-99m pertechnetate labeled red cell gated cardiac imaging in a patient with this tumor. We found that thallium and gated blood pool imaging can be used both in the diagnosis of these tumors and the assessment of the effects of chemotherapy on the tumor and normal myocardium. The thallium study was particularly helpful in identifying the malignant nature of the tumor by showing extensive infiltration into surrounding areas.
