his report describes two patients with a known history of Behçet's disease in whom massive hemoptysis developed from rupture of pulmonary artery aneurysms. The high recurrence rate of complications related to pulmonary artery aneurysms and even the aneurysms themselves due to inadequacy of medical therapy and the disadvantages of surgical treatment make these aneurysms candidates for endovascular management. The pulmonary artery aneurysms reported here were successfully treated with endovascular embolization using n-butyl cyanoacrylate. Pulmonary artery aneurysm embolization in Behçet's disease has been reviewed in the light of relevant literature.
