摘要：Background Immunocompromised individuals are susceptible to Cryptococcus and Mycobacterium tuberculo-sis infections.Coinfection can complicate diagnosis,and both may cause cerebral infarction.No previous reports describe cases of cryptococcal meningitis(CM)or tuberculous meningitis(TBM)with cerebrospinal fluid(CSF)testing positive for glial fibrillary acidic protein(GFAP)antibodies.
Methods We present the case of a 60-year-old man with chronic lymphocytic leukemia,initially diagnosed with TBM,who developed cerebral infarction and was found to test positive for CSF GFAP antibodies,later confirmed as CM.A focused literature review was performed for cases involving CM/TBM coinfection,cerebral infarction,and GFAP antibody positivity.
Results This case highlights overlapping clinical and imaging features of CM and TBM,including basal ganglia and thalamic infarctions.CSF GFAP antibody positivity became negative following antifungal therapy,indicating transient astrocytic injury.A literature search identified no prior reports describing CSF GFAP antibody positivity in leukemia patients with dual central nervous system(CNS)infections.
Conclusion CM and TBM present with overlapping features and may coexist with autoimmune encephalitis in immunocompromised patients.Incorporating autoimmune antibody testing,including anti-GFAP,into routine CNS infection evaluation can facilitate early recognition of immune-mediated pathology and guide timely antimi-crobial-immunomodulatory therapy.
