normal coronary artery. CAE can be found in up to 5% of angiographic and in 0.22% to 1.4% of autopsy series. It can be either diffuse affecting the entire length of a coronary artery or localized. When the dilatation involves the entire vessel, the word "ectasia" is used instead of an aneurysm. CAE or the aneurysm is attributed to atherosclerosis in 50% of cases, whereas 20-30% have been considered to be congenital in origin. In the great majority of these patients, ectasia coexists with CAD. Only 10-20% of cases of CAE have been described in association with inflammatory or connective tissue diseases. In the western population, the most common association had been with coronary atherosclerosis. Other conditions in which CAE or an aneurysm has been noted include Ehlers Danlos syndrome, polyarteritis nodosa, scleroderma, cystic medionecrosis, trauma, mycotic embolus, syphilitic aortitis, antineutrophil cytoplasmic antibody-related vasculitis, Kawasaki disease, and iatrogenic (angioplasty and atherectomy). 2-6
