Abstract

The incidence of Mycobacterium kansasii pulmonary diseases are on the increase in Korea with the higher probability of occurrence in middle-aged and older men with underlying lung diseases Among nontuberculosus mycobacterial (NTM) infections, the clinical features of M. kansasii pulmonary infection are most similar to those of tuberculosis (TB). The chest radiographic findings of M. kansasii infection are almost indistinguishable from those of M. tuberculosis (predominance of an upper lobe infiltration and cavitary lesions), even though some suggest that cavities are more commonly thin-walled and have less surrounding infiltration than those of typical TB lesions.
Although there are reports on the rare manifestations of M. kansasii infections, such as endobronchial ulcer, arthritis, empyema, cutaneous and mediastinal lymphadenitis, cellulites and osteomyelitis, the association with bronchial anthracofibrosis has not yet been reported.
This report describes the first case of M. kansasii infection presenting as a lung mass in the right lower lobe with accompanying bronchial anthracofibrosis.

Keywords: Mycobacterium kansasii, lung mass, anthracofibrosis
