Area postrema syndrome: Another feature of anti-GFAP encephalomyelitis:

Anti–Glial fibrillary acidic protein (GFAP) encephalomyelitis is a recently described entity and while the spectrum of this disease has been explored, further research is needed to fully describe its phenotype. Area postrema syndrome (APS) is usually associated with neuromyelitis optica spectrum disorders (NMOSDs), whereas no case of APS has been previously reported with anti-GFAP encephalomyelitis. In this article, we report a case of APS in a 41-year-old woman in the context of anti-GFAP encephalomyelitis. This case was not associated with additional anti-AQP4 IgG and therefore extends the clinico-radiological spectrum of anti-GFAP encephalomyelitis.
