Mixed nontuberculous mycobacteria in an immunocompromised patient with probable progressive multifocal leukoencephalopathy

Key Points

• Nontuberculous mycobacteria infections were found alongside progressive multifocal leukoencephalopathy (PML).
• The case highlights a complex clinical scenario in an immunocompromised patient, indicating a need for careful monitoring.
• Clinical observations and laboratory diagnostics reveal the significant role of nontuberculous mycobacteria in neurologic complications.
• These findings call for focused attention on potential dual infections in immunocompromised patients, which may complicate treatment.
