title: Saber-sheath trachea in a patient with bronchiolitis obliterans syndrome after lung transplantation.
abstract: Chronic rejection remains a major source of morbidity and mortality following lung transplantation. The clinical characteristics of chronic rejection involves bronchiolitis obliterans syndrome (BOS), which leads to progressive airway obstruction. Changes in intrathoracic tracheal dimensions and shape are commonly present in the setting of airway obstruction, leading to the narrowing of the intrathoracic trachea in the coronal plane with anteroposterior lengthening characteristic of the saber-sheath trachea deformity. We present a 64-year-old man who underwent left lung transplantation for idiopathic pulmonary fibrosis who later developed saber-sheath trachea as a result of chronic airway obstruction due to BOS.
