case_images: (A) Transthoracic echocardiogram of normal LV systolic function with an ejection fraction of 55% to 60% and large mobile echo density in the left atrium attached to the atrial septum; (B-E) cardiac magnetic resonance (CMR) imaging obtained for further characterization of the cardiac mass confirmed the presence of a large atrial mass attached to the fossa ovalis; (F) delayed gadolinium enhancement CMR with long inversion time suggested a thrombus.

case_images: Transthoracic echocardiogram showed normal left ventricular systolic function with an ejection fraction of 55% to 60% and large mobile echo density in the left atrium attached to the atrial septum (Figure 1 A). Cardiac magnetic resonance (CMR) imaging was obtained for further characterization of the cardiac mass (Figure 1 B-E), and it confirmed the presence of a large atrial mass attached to the fossa ovalis measuring 6.9 cm x 3.6 cm. Delayed gadolinium enhancement CMR with long inversion time (TI 600) showed lack of enhancement, which was suggestive of a thrombus (Figure 1 F).
