Imaging findings
Chest CT demonstrated classic findings of chronic airway infection, including tree-in-bud opacities and bronchiectasis, with a predominant basal distribution, suggestive of recurrent aspiration.
Key takeaways
This case highlights that *Mycobacterium gordoniae*, often considered an environmental contaminant or non-pathogen, can indeed cause true infection, especially in vulnerable populations such as the elderly (this patient was 91 years old) or immunocompromised individuals. The diagnosis was established by repeated positive cultures with a high burden of the organism and the absence of other identified pathogens. Imaging findings are typically indistinguishable from other non-tuberculous mycobacterial infections.
