Case of Severe Treatment-Resistant Cryptogenic Organizing Pneumonia

Abstract Cryptogenic organising pneumonia (COP) is a rare interstitial lung disease with different onset of symptoms, which responds rapidly to glucocorticoid treatment. We present a case of COP which manifested as progressive 3-year dyspnoea that has led ultimately to acute respiratory failure. Moreover, treatment with prednisone for this patient exhibits slow onset of the effect.
