Abstract

Background: Mycobacterium fortuitum complex (MTC) is a group of rapidly growing nontuberculous mycobacteria (NTM) that often develop in immunocompromised patients, while local NTM disease is most common in postoperative wound infections or invasion of the skin from wounds. Clinical case reports are rare, which often lead to tissue abscess and ulceration, and natural resistance to anti-tuberculosis drugs, difficult to control, long treatment process, mostly lasting more than half a year or even a year, and the therapeutic effect is relatively poor. The incidence of NTM-associated infections is increasing and is emerging as a global public health concern. Objective: To introduce the diagnosis and treatment of a case of soft tissue infection caused by Mycobacterium fortuitum in order to improve clinicians' understanding of the disease and deepen the understanding of bacteriological characteristics of the bacterium by microbiological examination personnel. Methods: Bacterial culture was performed in wound secretion, and MRI was performed to examine soft tissue infection. Result: Mass spectrometry analysis of bacterial culture of wound secretion showed Mycobacterium fortuitum infection. MR showed soft tissue infection and sinus formation in the posterolateral aspect of the right ankle. After diagnosis, the antibiotic regimen was adjusted to levofloxacin, amikacin, and rifampicin for triple anti-infection. One month later, the patient was discharged from the hospital for oral treatment with levofloxacin tablets, clarithromycin tablets and rifampicin capsules for 1 year and followed up for 1.5 years without recurrence. Conclusion: This paper can provide reference for etiological diagnosis, identification and treatment of non-tuberculous mycobacteria-related soft tissue infection.
