{Reference Type}: Case Reports {Title}: Pulmonary Mycobacterium abscessus Infection: A Pathogen in Disguise. {Author}: Waugh KM;Wajahat R; {Journal}: Cureus {Volume}: 15 {Issue}: 10 {Year}: 2023 Oct 暂无{DOI}: 10.7759/cureus.46897 {Abstract}: The incidence of infections caused by nontuberculous mycobacteria (NTM) is rising around the world, and they are becoming increasingly difficult to treat due to the bacteria being drug-resistant to several antibiotics commonly used in practice. Mycobacterium abscessus complex (MABC) is particularly difficult to treat as it is one of the most antibiotic-resistant species and, therefore, has limited treatment options that are effective at clearing the infection. We present the case of an 81-year-old female who was diagnosed with Mycobacterium abscessus after several hospital admissions in a short period of time for similar complaints, and we will discuss her diagnosis and possible treatment plan. This case explores the challenges that physicians face in diagnosing NTM infections due to them mimicking several other conditions and raises the importance of having a high clinical suspicion.
