Abstract

We present an unusual case of a 67-year-old woman with an incidental finding of a cardiac mass on a chest-computed tomography. Coronary angiotomography confirmed the diagnosis of a right coronary artery aneurysm, with 5.7x5.7 cm. Patient underwent aneurysm resection and coronary artery bypass graft surgery, with subsequent histologic study suggestive of arteritis sequela. Patients with giant coronary artery aneurysms are at high risk of complications and must benefit from aneurysm exclusion. This is a rare condition that can also be part of a systemic inflammatory disease.
