ABSTRACT
BACKGROUND:
Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is a recently identified recurrent meningoencephalomyelitis with GFAP immunoglobulin G presence in the serum or cerebrospinal fluid (CSF) as a specific biomarker. GFAP astrocytopathy is closely associated with the occurrence of some tumors and often coexists with other antibodies, such as the N-methyl-D-aspartate receptor and aquaporin-4 antibodies. However, GFAP astrocytopathy complicated by central nervous system infection is rare. CASE PRESENTATION Here, we present the case of a patient admitted to a local hospital due to a prominent fever and cough. The patient had a 1-month history of headaches before admission that were not considered serious at the time. Metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid revealed a high sequence number of Legionella pneumophila and a few mycobacteria. His cough and fever improved significantly after antibiotic treatment. Still, a slight headache remained. Subsequently, his condition worsened, and he visited our hospital with a disturbance of consciousness. Mycobacterium tuberculosis was detected with mNGS of the CSF, while the CSF and serum were also positive for GFAP antibodies. Following anti-tuberculosis and steroid therapy, the patient's symptoms improved, and he tested negative for the GFAP antibody.CONCLUSION:
This is the first reported case of GFAP astrocytopathy complicated by tuberculous meningoencephalitis. Due to overlaps in the clinical manifestations of the two diseases, GFAP astrocytopathy is sometimes misdiagnosed as tuberculous meningoencephalitis. Therefore, in addition to ensuring careful identification of the two diseases, clinicians need to be aware of their possible co-existence.Palavras-chave
