Mycobacterium avium intracellulare complex (MAC) usually causes an opportunistic pulmonary infection in immunocompromised hosts who have underlying structural lung disease. Central nervous system infection due to MAC is very rare even in an immunocompromised host. Most previous reports of central nervous system infection due to MAC have been meningoencephalitis in patients infected with human immunodeficiency virus (HIV). Only four cases of brain abscess due to MAC have been reported worldwide. We report a case of brain abscess due to MAC in a non-HIV patient. Although drugs used for treatment of MAC have limited central nervous penetration, an azithromycin-based antituberculous therapy after surgical drainage of the abscess showed improvement. To the best of our knowledge, this is the first reported case of MAC brain abscess in the Korean literature.
