Abstract Background Neuromyelitis Optica Spectrum Disorder (NMOSD) is an autoimmune relapsing disease involving the central nervous system with predominant inflammatory attack of optic nerves, spinal cord and area postrema, often leading to severe disability. Women with NMOSD typically experience adverse pregnancy outcomes and high relapse rates during pregnancy and the postpartum period. Case report Herein we present a case of pregnancy in a young NMOSD woman treated with tocilizumab. The course of her pregnancy was clinically unremarkable and treatment whit Tocilizumab was well tolerated. Conclusions This case raises the possibility that the modulation of immune system by inhibitors of the IL-6 pathway could a promising therapeutic option for pregnancy in NMOSD patient.
