Embolization of pulmonary artery aneurysms in a patient with Behçet's disease complicated by coil erosion into the airway.

Behçet's disease is an inflammatory vasculitis with the unique feature of pulmonary artery aneurysms. We describe a patient with Behçet's disease and pulmonary artery aneurysms who presented with massive hemoptysis treated by coil embolization. Although there was immediate resolution of hemoptysis and improvement in hemodynamic status, 2 months later the patient reported a refractory cough and feeling of foreign body in her throat. Imaging demonstrated partial coil migration into the bronchus and trachea. Although endovascular intervention is the first-line treatment for massive hemoptysis, in patients with Behçet's disease, active inflammation and chronic steroid use may increase the risk of coil erosion and migration.
