Malignant lymphoma presenting as a cardiac tumor.

We report a case of malignant lymphoma whose initial symptoms were heart failure. An echocardiogram showed a large tumor in the right ventricle, and a definitive diagnosis was obtained at autopsy. Of particular interest in our case, the lymphoma was confined to the heart and a mediastinal lymph node, with its greatest bulk being intracardiac. This case is a rare manifestation of malignant lymphoma.
