case_images: Electrocardiogram showed 1 mm ST segment elevation in anterior chest leads (Figure 1).
case_images: (a) Transesophageal echocardiogram of 4-chamber view showing tumor mass (T) compressing the left atrium (LA). A pericardial effusion (PE) is adjacent to the left ventricular (LV) free wall. RV = right ventricle. (b) Transesophageal echocardiogram of left ventricular (LV) outflow tract in long axis showing homogenous tumor (T) mass with lucent spaces (*) compressing the left atrium (LA). AO = Ascending aorta. RV = right ventricle.

case_images:  Transesophageal echocardiogram showed global LV severe hypokinesis with ejection fraction (EF) of 10 percent and a large mass indenting the left atrium and pulmonary veins (Figures 2(a) and 2(b)).
case_images: Computed axial tomogram showing a mass in left anterior mediastinum at the root of pulmonary artery with right anterior pericardial involvement and effusion.

case_images: CT scan, a large superior mediastinal mass extended to the aortopulmonary window and abutted the aortic arch and pulmonary artery (Figure 3). CT guided biopsy revealed thymoma with undifferentiated cells. 
case_images: Parasternal long-axis views showing severe baseline LV dysfunction (Figures 4(a) and 4(b)) and improved ejection fraction on the followup study (Figures 4(c) and 4(d)).

case_images: A repeat echocardiogram several days later showed improved LV function with an EF of 45% (Figure 4).
case_images: Histopathology demonstrating multinucleated giant cells and numerous lymphocytes infiltrating the cardiomyocytes.

case_images: Histological examination of the myocardium showed large multinucleated epitheliod cells, plasma cells, and lymphocytes characteristic of GCM (Figure 5).
