We describe the case of a 53-year-old woman who undergoes total splenectomy and later presents with aquaporin-4 antibody positive neuromyelitis optica (NMO). The occurrence of NMO after acquired immunosuppression raises the possibility of NMO as a form of secondary autoimmunity.
Keywords: Aquaporin-4 antibody; Neuromyelitis optica; Secondary autoimmunity; Splenectomy.
