case_images: Transthoracic echocardiography showed the cardiac mass (30 mm x 28 mm) located in the right atrium and the anterior tricuspid valve was partially obstructed by the mass but the flow velocity of tricuspid valve did not accelerate. (RA, right atrium; RV, right ventricle; TV, tricuspid valve).

case_images: The anterior tricuspid valve was partially obstructed by the mass, but the flow velocity of tricuspid valve did not accelerate (Figure 1).
case_images: (A,B) The cardiac magnetic resonance imaging showed that showed that a well-circumscribed, homogenous "shadow" in the right atrium; it measured 29 mm x 27 mm, had equal T1- and T2-weighted signal intensities, was adjacent to the tricuspid valve.

case_images: Cardiac magnetic resonance imaging (cMRI) showed that a well-circumscribed, homogenous "shadow" in the right atrium; it measured 29 mm x 27 mm, had equal T1- and T2-weighted signal intensities, was adjacent to the tricuspid valve (Figure 2).
case_images: (A,B) The 18F-fluorodeoxyglucose positron emission tomography combined with computed tomography showed that a dense circular shadow was in the right atrium abutting the tricuspid valve (32 x 34 mm), and there was no increase in glucose metabolism.

case_images: There was no increase in glucose metabolism, and the tumor was considered benign (Figure 3).
case_images: (A) The intraoperative image showed that the mass, with a firm-hard texture, was confirmed to be partially embedded in the right atrium. (B) The histopathological examination revealed that the mass consisted of abundant calcific deposits without malignant cells.

case_images: Without cardiac arrest, the right atrium was opened, and the mass, with a firm-hard texture, was confirmed to be partially embedded in the right atrium (Figure 4A). Histopathological examination revealed that the mass consisted of abundant calcific deposits without malignant cells (Figure 4B).
