ABSTRACT
A 69-year-old man with diabetes mellitus was found to have cavitary shadows in the upper lobes of both lungs during a systemic examination. Mycobacterium malmoense was detected in his sputum, and he visited our hospital because the shadows deteriorated. Rifampicin, ethambutol, and clarithromycin were successfully administered, and the inflammatory and imaging findings improved. His lower respiratory tract specimen was cultured in Ogawa medium at 37°C for 8 weeks, with no detection of any pathogens. His sputum was then cultured at 28°C for 12 weeks, and M. malmoense was detected in it. In mycobacterial culture, it is important to select the appropriate culture conditions for the species in question.
