AI Article Synopsis
- * The typical forms of MAC pulmonary infections include fibrocavitary and nodular bronchiectatic presentations; however, this case highlights a rare instance of multiple cavitary nodular lung infections, differing from usual presentations.
- * The study demonstrates that percutaneous transthoracic needle aspiration can be an effective diagnostic tool for evaluating rare cases of multiple cavitary nodules associated with MAC infection.
Article Abstract
Nontuberculous mycobacteria (NTM) have been increasingly recognized as an important cause of chronic pulmonary infections. The Mycobacterium avium complex (MAC), which is composed of two species, Mycobacterium avium and Mycobacterium intracelluare, is the most commonly encountered pathogen associated with NTM lung disease. MAC pulmonary infection typically presents in a fibrocavitary form or a nodular bronchiectatic form. However, there have been atypical presentations of MAC pulmonary infections, including solitary pulmonary nodules (SPN). There have been several previous reports of SPN due to MAC infection in the United States, Japan, and Korea. In 2009, Sekine and colleagues reported a case of MAC pulmonary infection presenting with multiple nodules. To date, however, there have been no cases of NTM lung infection with multiple cavitary pulmonary nodules, and neither a fibrotic change nor nodular bronchiectasis. The present case showed a multiple cavitating nodular lung infection due to MAC, which is very rare and different from the typical presentation of MAC pulmonary infections. We also showed that percutaneous transthoracic needle aspiration can be a useful diagnostic tool to evaluate a case of multiple cavitary nodules.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Mycobacterium avium complex (MAC) is an emerging pathogen leading to public health concerns in developing and developed countries, particularly among immunocompromised individuals and patients with structural lung diseases. Current clinical guidelines recommend combination antibiotic therapy for treating MAC pulmonary disease (MAC-PD). However, the rising prevalence of antibiotic resistance poses significant challenges, including treatment failure and clinical recurrence.

Background: Nontuberculous mycobacteria (NTM) are emerging pathogens responsible for increasing skin and soft tissue infections (SSTIs) globally. However, the diagnosis and treatment of NTM SSTIs face significant challenges due to the lack of standardized guidelines. This study reviewed the clinical characteristics, diagnostic challenges, and treatment outcomes of NTM SSTIs in a large cohort from a tertiary referral center in Beijing, China.
