title: Intractable heart failure, conduction disturbances and myocardial infarction by massive myocardial invasion of malignant lymphoma.
abstract: A patient with malignant lymphoma who developed congestive heart failure, conduction disturbances and myocardial infarction is presented. Two-dimensional echocardiography revealed marked thickening of the left ventricular wall, where the gallium scan correspondingly showed an abnormal accumulation. Irradiation to the mediastinum resulted in a dramatic decrease in ventricular wall thickness and disappearance of the gallium accumulation. Postmortem examination confirmed previous lymphomatous involvement of the myocardium. Combined techniques, including echocardiography and gallium scan, can be valuable for noninvasive detection and follow-up of myocardial involvement in patients with malignant lymphoma.
