title: Congenital giant aneurysm of the left coronary artery.
abstract: We report an unusual case of congenital giant coronary aneurysm. A 23 year-old male with a history of acute myocardial infarction presented an abnormal shadow in the left cardiac border on routine X-ray. Electrocardiogram and physical examination were normal without any clinical signs of inflammation, but computed tomography (CT) scan and cardiac magnetic resonance imaging (MRI) revealed a giant (>50mm) coronary aneurysm. Coronary artery bypass grafting (CABG) with coronary artery aneurysm (CAA) resection resolved the CAA. Coronary artery aneurysms are entities of localised dilation and can be common events in chronic infectious disease as a result of the systemic inflammatory state; however, giant coronary aneurysms (measuring more than 50mm) are rare. This is especially true where the pathological aetiology was not clearly defined or was believed to be of congenital origin. To date only a few published case reports exist for this type of pathological entity.
