Giant calcified pseudoaneurysm of right coronary artery presenting as a right intra-atrial mass.

We present a case of a giant right coronary artery pseudoaneurysm that presented as a right atrial intracardiac mass. Preoperatively, a two-dimensional echocardiogram, a computed tomographic scan, a magnetic resonance image, and cardiac catheterization were performed to diagnose and assess the origins of the mass.
