Pulmonary artery aneurysms in Behçet’s disease

Behçet’s disease is the most common cause of pulmonary artery aneurysms. Pulmonary artery aneurysms are rare, but they are life-threatening because of their high tendency to rupture. However, there is also a chance that the aneurysms may completely resolve with immunosuppressive therapy. A 30-year-old man was admitted with chest pain, painful oral and genital ulcers, skin rash, weakness, and intermittent hemoptysis. He had a history of Behçet’s disease for 6 years. The chest radiography showed a round opacity superior part of hilus on right. The helical thoracic computed tomography (CT) angiography demonstrated pulmonary aneurysms associated with Behçet’s disease. The patient was successfully treated with colchicine, corticosteroids, and cyclophosphamide. A discussion about pulmonary artery aneurysms associated with Behçet’s disease is provided in this case.
