case_images: (A) Echocardiography at diagnosis. The apex of the left ventricle and left atrium displayed mass echoes protruding into the pericardial cavity, measuring 3.7x3.4cm and 2.3x1.2cm, respectively. (B) Echocardiography after four weeks of initiation of systemic chemotherapy. Significant reduction in the size of the mass to 2.2x0.7cm; the mass on the apex of the left atrium and pericardial effusion are no longer displayed. (C) Echocardiography after two months. The masses around the left ventricle and left atrium, pericardial effusion are not displayed. LA=left atrium; RA=right atrium; LV=left ventricle; RV=right ventricle.

case_images: Notably, the left ventricular apex and left atrium displayed mass echoes protruding into the pericardial cavity, measuring 3.7x3.4cm and 2.3x1.2cm, respectively ( Figure 1A ). A follow-up echocardiogram conducted four weeks after initiating systemic chemotherapy demonstrated a significant reduction in the left ventricular apex mass (2.2x0.7cm) ( Figure 1B ), along with the normalization of other myocardial echogenicity and contractility. Two months later, the cardiac mass completely disappeared ( Figure 1C ), and bone marrow aspiration performed on day 50 of treatment did not show any residual leukemia.
case_images: CT scan of the chest and abdomen at diagnosis. CT showed that not only the heart but also the chest, abdomen, and pelvis were involved.
