Relapsing Polychondritis Affecting the Lower Respiratory Tract

Abstract
OBJECTIVE. The purpose of this study was to describe the CT findings of lower respiratory tract involvement by relapsing polychondritis. CONCLUSION. The most common CT manifestations were increased attenuation and smooth thickening of airway walls. Tracheal or bronchial stenosis was less common. Airway collapse and lobar air trapping were seen in half of patients examined with expiratory CT.
