title: Lymphoma of the heart.
abstract: A case of malignant lymphoma involving the heart is reported. The patient presented with symptoms of cardiac decompensation. The echocardiographic findings of an echogenic mass arising from the pulmonary valve as well as demonstration of soft tissue density diffusely infiltrating the heart and mediastinum was confirmed by computer tomography and angiography. Although the findings on the noninvasive studies were highly indicative of tumor involvement, the temporal association of the symptoms to a motor vehicle accident lead to the erroneous diagnosis of intracardiac and mediastinal hematoma.
