A 71-year-old woman was admitted to our hospital for evaluation of a chest X-ray abnormality. Heart murmur was not heard. Chest X-ray showed a bulge with calcification at left third arch. Chest computed tomography revealed contrast enhancement of masses, which appeared to originate from the vascular system. Coronary angiography demonstrated multicystic aneurysmal dilatation of a coronary artery fistula originating from the proximal left descending and right coronary artery. Electrocardiography showed no remarkable findings and a treadmill exercise test showed no significant ST-T change. The size of the mass of 3 cm in diameter on chest X-ray remained the same for two years. We concluded that surgery was not necessary immediately. In Japan, nineteen cases of coronary-pulmonary artery fistula with multicystic saccular aneurysms have been reported in the literature, including our case. The majority of these cases are elderly women from fifty to sixty years old.
