Contrast echocardiographic and computed tomographic images. (A) Contrast-enhanced echocardiographic image obtained after intravenous injection of lipid-encapsulated microbubbles. The apical four-chamber view demonstrates normal left ventricular opacification and low opacification of the tumoral mass. LA, left atrium; LV, left ventricle; RA, right atrium; TU, tumoral mass. (B) Computed tomographic image demonstrating a septate cystic mass containing septal calcification, which was continuous to the pericardium and caused extrinsic compression of the right atrium.
