We report the case of a 34-year-old female patient with a giant thrombus-filled aneurysm of the right coronary artery presenting as a spherical cardiac mass on echocardiography. The cardiac mass was found to be an 8-cm right coronary artery aneurysm on cardiac magnetic resonance imaging, which also revealed a 3.5-cm proximal left coronary aneurysm and a very small aneurysm at the origin of the obtuse marginal coronary artery. Due to the extent and size of the right coronary aneurysm, a decision for surgical intervention was made. Resection of the right coronary artery aneurysm with vein graft replacement and a bypass to the left anterior descending followed by subsequent exclusion of the aneurysm was successfully performed.
