A round, echo-dense structure was visualized in the left atrioventricular groove region (Fig. 1, upper panels). A transesophageal echocardiographic examination (TEE) was performed to better evaluate this intracardiac mass (Fig. 1, lower panels).
Transesophageal visualization of the mass (left panel) and trans-esophageal examination repeated nine months later, showing the disappearance of the mass (right panel). LV: left ventricle; LA: left atrium; RA: right atrium; Ao: Aorta; *: Caseous calcification of the mitral annulus.

The mass had sharp and distinct borders, with an echogenicity distinct from that of the adjacent myocardium (Fig. 2, left panel). A TEE conducted nine months later revealed the disappearance of the mass (Fig. 2, right panel).
