Pulmonary arterial aneurysm is defined by a dilation of the pulmonary artery. It should not be confused with a false aneurysm; Witch is due to a breach in the vessel wall. Known since the 18th century when syphilis and tuberculosis were endemic, aneurysms of the pulmonary artery became rare with the advent of antibiotics. In Behçet's disease, arterial involvement is rare and has a poor prognosis. We report a case of bilateral aneurysms involving the lobar and segmental pulmonary arteries during Behçet's disease in a 45-year-old patient who presented with hemoptysis. The chest X-ray showed bilateral round pulmonary opacities. The thoracic CT scan showed multiple bilateral aneurysms of the lobar and segmental pulmonary arteries. The evolution was spectacular under medical treatment. The peculiarity of this case lies in the rarity of arterial involvement during Behçet's disease in general and in the rarity of the segmental arterial involvement in particular; as well as in the good evolution under medical treatment even with the presence of hemoptysis.
