Behçet’s disease and pulmonary involvement

Behçet’s disease (BD) is a systemic vasculitis involving arteries and veins of all sizes and is characterized by a heterogeneous spectrum of clinical manifestations, including mucocutaneous, ocular, vascular, and neurological involvement, typically following a relapsing-remitting course. Although thoracic involvement is infrequent, it can affect various anatomical structures within the chest and present with a wide range of clinical symptoms. Pulmonary artery involvement may lead to life-threatening complications such as pulmonary artery aneurysms (PAAs) and pulmonary artery thrombosis (PAT), which are significant causes of mortality in BD. Timeyl diagnosis, appropriate radiological assessment, prompt initiation of immunosuppressive therapy are critical to reducing morbidity and mortality. This review provides an overview of the pulmonary manifestations of BD.
