RT Journal Article SR Electronic T1 Recurrent Nontuberculous Mycobacterial Tenosynovitis JF Ochsner Journal JO Ochsner J FD O. P. Jindal Global University SP 86 OP 89 DO 10.31486/toj.19.0010 VO 21 IS 1 A1 Melissa Kwan A1 Richard Tupler YR 2021 UL http://www.ochsnerjournal.org/content/21/1/86.abstract AB Background: Nontuberculous mycobacteria are an uncommon pathogen for musculoskeletal infection and are difficult to treat because of delays in diagnosis, prolonged treatment requiring both antimycobacterial therapy and surgical debridement, and high rates of resistance to antimycobacterial therapy.Case Report: We report the case of an 88-year-old male with recurrent Mycobacterium avium complex tenosynovitis despite receiving multiple courses of pharmacologic therapy and surgical debridement.Conclusion: Nontuberculous mycobacterial musculoskeletal infections can be difficult to diagnose and equally difficult to treat. A combination of antimycobacterial therapy and surgical debridement is often required; however, the rate of treatment failure remains high, particularly with rapidly growing mycobacteria such as Mycobacterium avium.
