Complete regression of myocardial involvement associated with lymphoma following chemotherapy

Figure 1 Transthoracic echocardiography - 4-chamber view. A: Before chemotherapy, the echocardiogram showed tumor infiltration of the myocardium of both atria and the atrial septum (see arrow); B: After chemotherapy, the echocardiogram showed total regression of myocardial infiltration. RA: Right atrium; RV: Right ventricle; LA: Left atrium; LV: Left ventricle.

Figure 2 Transthoracic echocardiography - parasternal long-axis view. A: Before chemotherapy, the echocardiogram showed tumor infiltration of the aorta (see arrows). B: After chemotherapy, the echocardiogram showed total regression of aortic infiltration. LA: Left atrium; LV: Left ventricle; Ao: Aorta.
