CTICasesGiant Right Coronary Artery Aneurysm
Imaging findings
CT angiography and coronary catheterization show a giant, thrombosed aneurysm of the right coronary artery with turbulent residual flow, which was partially treated with coil embolization.
Key takeaways
Giant coronary artery aneurysms (measuring >20 mm) are rare, typically caused by severe atherosclerosis, Kawasaki disease, or congenital anomalies. They carry a high risk of thrombosis, distal embolization, or rupture, and are managed with surgical exclusion or endovascular coil embolization.
