title: [Pulmonary tuberculosis with atypical radiological findings in a patient with chronic obstructive pulmonary disease].
abstract: A 77-year-old-man who had been treated for chronic obstructive pulmonary disease (COPD) was referred to our hospital for further examination of a chest X-ray abnormality. The chest X-ray showed consolidation in the right upper and middle lung field. Chest computed tomography showed an airspace consolidation extending subpleurally and nonsegmentally without nodular lesions. The tentative diagnosis was cryptogenic organizing pneumonia. However, bronchoalveolar lavage fluid was positive for acid-fast bacilli on smear and also positive for tuberculosis PCR, leading to a diagnosis of tuberculous pneumonia. Tuberculous pneumonia in COPD patients can be non-segmental and mimic organizing pneumonia.
