Figure 1: Echocardiographic subcostal four-chamber view (a) demonstrating a heterogeneous mass (arrow) with multiple hypolucent cystic areas compressing the right atrium, with mild pericardial effusion. Unobstructed superior vena cava flow on color Doppler (b). The tumor mass measures 5 cm × 3.5 cm on subcostal coronal view (c). LV: Left ventricle, RV: Right ventricle, LA: Left atrium
