Pulmonary artery aneurysm (PAA), especially the peripheral type, is a rare disease. We report 2 cases of peripheral PAA with pulmonary artery hypertension. Complication associated with peripheral PAA was hemoptysis. Endovascular coil embolization was performed successfully in one patient. The other with peripheral PAA was died of massive hemoptysis. In patients with peripheral PAA, coil embolization is one therapeutic option. We summarized cases with peripheral PAA in Japan.
