Objective To analyze the clinical presentations and radiological characteristics of pathologically proved cases of cryptogenic organizing pneumonia(COP).Methods The clinical and radiological features of 8 patients with COP confirmed by open lung biopsy were analyzed.Treatment and follow-up data were also recorded.Results There were 5 male an 3 female patients aged 37 to 68 years.Dyspnea,cough and inspiratory crackles were the most common symptoms and signs.Various computed tomography findings including ground glass opacities,pathy consolidation with air bronchograms,nodules and reticulation were simultaneously observed in the same patient.The diagnostic imaging features of COP were patchy or lobar consolidation,often by a predominantly subpleural distribution,and irregular band-like opacities distributed along the bronchovascular bundle or located in the subpleural area.All patients were treated with corticosteroids and yielded significant improvement in seven cases.Conclusions COP could be diagnosed by clinical and radiological findings and histopathological examination was needed for confirmed diagnosis.In general,COP responds well to glucocorticoid therapy and has a benign prognosis.
