title: Metastatic cardiac tumor demonstrated by 201thallium scan.
abstract: A patient with bronchogenic carcinoma had an electrocardiogram that was initially thought to be consistent with myocardial infarction and possible left ventricular aneurysm. A heart scan with radioactive 201thallium showed an area of sharply diminished uptake ("cold spot"); however, subsequent thoracotomy showed that this was caused by local pericardial and myocardial infiltration by tumor. This suggests a role for radioactive 201thallium in the detection of cardiac metastatic tumors.
