title: [A case of Mycobacterium avium lung infection with a pleural effusion].
abstract: Pleural effusions seldom accompany nontuberculous mycobacterial infections. We reported one such case of M. avium lung infection with pleural effusion. A 40-year old male was admitted to our hospital complaining of right chest pain and general fatigue. His chest X-ray showed a consolidation in the right lower lung field. The day after admission, a right pleural effusion appeared. The fluid was exudative and microbiological examinations of the effusions, including staining and culturing, proved negative. However, one month afteradmission, acid fast bacilli were observed in his sputum and a subsequent sputum culture specimen revealed the presence of M. avium. Treatment with antimycobacterial agents was promptly commenced and the patient's effusion and lung consolidation was gradually resolved.
