Coronary artery aneurysms are described as a localized dilatation that exceeds the normal diameter by 1.5 times. This is a rare condition; its incidence varies from 0.3% up to 5.3% of all coronary angiographies. Those aneurysms that exceed 4 times the diameter of a normal artery are considered giant aneurysms, which are even more uncommon, presenting between 0.02% and 0.2% of all cases. There is controversy regarding its pathophysiology, however, up to 50% of the cases are related to atherosclerosis. They are diagnosed more frequently between the sixth and seventh decade of life. The main clinical manifestations are related to ischemic heart disease. Regarding their treatment, there is no general consensus toward its management in adult patients. The options are medical, surgical, or percutaneous treatment. We report the presence of a giant aneurysm of the right coronary artery and giant ectasia of the left coronary system with active thrombosis in a man with a history of an abdominal aortic aneurysm, with endovascular treatment and a non-ST segment elevation myocardial infarction with no reperfusion strategy, who required a coronary computed tomography, identifying the anatomical characteristics of this disease.
