title: Primary right cardiac tumor. Detection by echocardiographic and radioisotopic studies.
abstract: A primary tumor of the right atrium and right ventricle was detected in a 17-year-old male patient by noninvasive techniques, ie, M-mode echocardiograms and gated blood-pool cardiac scan combined with myocardial imaging with radioactive 201thallium. The clinical presentation was unusual, and validation of the echocardiographic and isotopic findings was obtained by contrast angiograms. Surgical pathologic findings defined the tumor as a poorly differentiated sarcoma.
