After corticosteroid treatment, her pulmonaryfunction improved.CONCLUSIONIn such cases, our experience suggested that 18F-fluorodeoxyglucose positronemission tomography/computed tomography (18F-FDG PET/CT) and fiberopticbronchoscopy should be used to diagnose airway chondritis as relapsing polychondritisin the early phase of disease.展开更多
