Abstract

The Mycobacterium avium-intracellulare complex (MAC) is the most common pathogen in pulmonary disease caused by a nontuberculous mycobacteria. Patients with MAC pulmonary disease tend to be older, are more likely to have underlying lung disease than tuberculosis patients. The insidious nature of MAC pulmonary disease has been emphasized in many reports because symptoms may be present for months or years before a diagnosis can be made. Most patients experience chronic coughing, which is usually productive of purulent sputum. A MAC pulmonary infection is rarely accompanied by acute respiratory symptoms and lobar pneumonic consolidation on chest radiography. We report a very rare case of M. intracellulare pulmonary disease presenting as acute pneumonia.
