Cryptogenic organizing pneumonia (COP) is an idiopatic condition characterized by granulation tissue extending to alveolar ducts and alveoli in small airways. Here, we present an exemplary case for COP which is uncommon in clinical practice of chest diseases. A 48-year-old male was admitted to our clinic with shortness of breath and cough. In arterial blood gas collected at room air, pH was 7.43, PaCO2 was 41.2 mmHg, PaO2 was 49.1 mmHg, and HCO3 was 24mEq/L. In thorax HRCT, ground-glass-opacities accompanied by bilateral consolidation areas were present especially in peripheral areas of the right lung and bilateral upper lobes. COP was reported histopathologically in transbronchial biopsies performed with bronchoscopy. Significant clinical improvement and radiological regression were observed in the patient with 80 mg/day methylprednisolone treatment. We share the case of our patient, who was diagnosed with bronchoscopic procedure without the need of open lung biopsy, to remind the importance of bronchoscopy in the diagnosis of COP.
