Case of severe treatment-resistant cryptogenic organizing pneumonia

Abstract

Cryptogenic organizing pneumonia is a rare interstitial lung disease with different onset of symp-toms, which responds rapidly to glucocorticoid treatment. We present a case of cryptogenic organizing pneumonia which manifested as a progressive 3-year dyspnea that ultimately has led to acute respiratory failure. Moreover, treatment with prednisone for this patient exhibited slow onset of the effect.
