Key points: Obstructive airway disorders

• Obliterative bronchiolitis can occur with autoimmune conditions, inhalational toxin exposures, infections, and posttransplantation and may present with irreversible airflow obstruction and mosaic pattern on high-resolution computed tomography

• Bronchiolitis obliterans syndrome represents a chronic allograft rejection in lung transplant recipients and is the leading cause of death beyond 1 yr after lung transplantation

• Paradoxical vocal fold motion disorder can mimic asthma with a presentation that includes dyspnea, upper airway wheezing, and/or stridor

• Bronchiectasis may be idiopathic or caused by infections, congenital disorders, inflammatory diseases, immunodeficiencies, and reflux
