Introduction: Glial fibrillary acidic protein (GFAP) astrocytopathy is a novel autoimmune neurological disorder and is diagnosed by GFAP-IgG in cerebrospinal fluid (CSF) measurement. Case report: Herein, we described a 10-year-old boy with abnormal neurological symptoms and signs. GFAP-IgG was detected in CSF using cell-based assay (CBA), and his CSF showed an increase in lymphocytes, a slight decrease in glucose and an increase in protein level in the early stage. The cranial MRI showed multiple strips of T2-FLAIR hyperintense signal changes on the surface of medulla oblongata, pons, and gyrus in bilateral cerebral hemispheres. He was treated with immunoglobulin (IVIG) and high-dose methylprednisolone pulse treatment, and his clinical presentations gradually improved. Conclusion: We highlight that patients with normal inflammatory markers in peripheral blood have obvious meningitis-like symptoms, and clinicians need to consider GFAP astrocytopathy. The early diagnosis and treatment of GFAP astrocytopathy are important for improving the prognosis.
