We report an operative case of bilateral peripheral pulmonary arterial aneurysms. The patient was a 62-year-old woman complaining of fever. She was pointed out coin lesions at the left hilus region and the right lower lung field. Chest CT and pulmonary arteriography revealed saccular dilatation of the bilateral peripheral pulmonary artery. We diagnosed bilateral peripheral pulmonary arterial aneurysms. The lesions were located in the left upper lobe and the right lower lobe. As a literature review emphasized the necessity of resection whenever this diagnosis is made, so as to prevent a fatal outcome due to aneurysmal rapture, a left A 3 aneurysmectomy was successfully performed, and a right A8 aneurysmectomy was performed 2 months later. Histological examination of the resected specimen revealed that the pulmonary artery had marked aneurysmal dilatation of the lumen. There was no evidence of specific chronic inflammation or arteriosclerosis in the artery. Eleven such cases including this case were reported in Japan.
