Meanwhile, mixed bacterial meningitis is a rare entity. However, it is difficult to identify anaerobic pathogens using traditional culture methods. Disorders such as neurosurgical interventions are considered risk factors for the development of such cerebral infection. Early diagnosis and appropriate therapy may contribute to patient survival.Case Presentation: We report the use of metagenomic next-generation sequencing (mNGS) to facilitate the diagnosis and treatment of polymicrobial meningitis in a 35-month-old male child with a history of detethering procedure for tethered cord syndrome (TCS). The mNGS tests identified six bacterial species from CSF specimens, including four ones of anaerobic bacteria. The subsequent examination of magnetic resonance imaging (MRI) revealed abnormal imaging findings of the lumbosacral area. The patient eventually recovered from severe infections due to long-term antibiotic treatment and radical surgery.Conclusion: This case demonstrates the advantages of mNGS for the rapid and accurate diagnosis of mixed bacterial meningitis, highlighting its application of identifying uncommon pathogens in severe infections. For patients who suffered from exacerbated brain infection with history of detethering surgery, anaerobic cultivation is needed and empiric antibiotic therapy should consider mixed infection in these situations.Keywords: meningitis, metagenomic next-generation sequencing, children, case report
