Bronchiolitis Obliterans Organizing Pneumonia 1 례 = A Case of Bronchiolitis Obliterans Organizing Pneumonia

다국어 초록 (Multilingual Abstract)

Bronchiolitis obliterans organizing pneumonia (BOOP) is a type of diffuse interstitial lung disease that primarily affects the small conducting airways and presence of granulation tissue plug within the lumen of small airways that sometimes completely obstruct the airways and extend into alveolar ducts and alveoli with a variable degree of interstitial infiltration of mononuclear cells. BOOP may be seen with infections, drugs, connective tissue diseases, toxic-fume exposure, allergy and idiopathic, it is differentiated from bronchiolitis obliterans that is not associated with organizing pneumonia, We experienced a case of idiopathic BOOP. The patient was a 11 year old girl presented with 45 days history of exertional dyspnea and 21 days coughing. The physical examination showed chronic ill-appearance and rales on both lung. Chest X-ray and high resonance chest CT showed bilaterally diffuse ground glass opacities. Thoracoscopic lung biopsy carried out and showed characteristic findings of BOOP. After prednisolone therapy, dyspnea and coughing disappeared and chest X-ray finding was improved. We report a case of BOOP with brief review of related literatures.
