Background: Central nervous system (CNS) mucormycosis is a rare，life-threatening 4 fungal infection predominantly affecting diabetic and immunocompromised patients. 5 Early diagnosis remains challenging, resulting in poor outcomes. We report a case 6 highlighting the diagnostic challenges and rapid progression in a patient with 7 uncontrolled diabetes and COVID-19 infection. Case Presentation: A 31-yearold male with untreated type 2 diabetes mellitus 13 presented with severe pneumonia due to COVID-19 infection. His condition rapidly 14 deteriorated, developing CNS symptoms and characteristic nasal lesions. Cerebrospinal 15 fluid (CSF) analysis revealed lymphocytic pleocytosis, high protein, and low glucose. 16 Metagenomic next-generation sequencing (mNGS) of CSF confirmed Rhizopus oryzae 17 infection. Despite initiating amphotericin B therapy, his condition worsened. Results: The patient succumbed to progressive multi-organ failure 26 secondary to disseminated mucormycosis. This case emphasizes the significance of 27 uncontrolled diabetes and COVID-19 as critical risk factors and highlights the 28 diagnostic utility of CSF mNGS. Conclusion: Prompt recognition of risk factors, early utilization of advanced diagnostic 34 methods, and aggressive treatment are essential to improve outcomes in CNS 35 mucormycosis.
