Autoimmune glial fibrillary acid protein astrocytopathy initially misdiagnosed as tuberculous meningitis: a case report

The clinical manifestations of autoimmune glial fibrillary acid protein astrocytopathy often include encephalitis, meningoencephalitis, meningoencephalomyelitis, and optic neuritis. These early manifestations are similar to those of central nervous system infections, where autoimmune glial fibrillary acid protein astrocytopathy is commonly misdiagnosed as tuberculous meningitis, early detection of glial fibrillary acid protein-immunoglobulin G antibody in cerebrospinal fluid is essential for differential diagnosis.
