In the United States, Mycobacterium avium complex (MAC) has been found to be the most common isolate in non-tuberculous disease, and pulmonary infection is the most frequent presentation. It is ubiquitous in the environment, particularly in soil and manufactured water supply sources. Worldwide, M. avium infections, both pulmonary and disseminated, are steadily increasing. Due to MAC’s ability to cause non-specific symptoms and its pervasiveness within the environment, it is paramount to incorporate this diagnosis in the differential, especially in those most susceptible. We report a case of a Mycobacterium avium complex pulmonary infection in 72-year-old Caucasian male with history of chronic immunosuppression and large hiatal hernia, highlight the imaging features, and discuss the importance of maintaining awareness in immunocompromised hosts.
