We report two cases of autoimmune GFAP astrocytopathy(GFAP-A). Cases were a man in his 70s, and a woman in her 50s. Both presented with hyponatremia and bladder-rectal dysfunction. Gadolinium-enhanced brain MRI revealed enhancement, and both were diagnosed with GFAP-A based on the presence of anti-GFAPα antibodies in cerebrospinal fluid. Steroid pulse therapy led to clinical improvement in both cases. GFAP astrocytopathy(GFAP-A), a clinically relevant subtype of autoimmune meningoencephalitis first identified by Fang et al. (2016). should be considered in patients exhibiting characteristic clinical and radiographic findings.
