Neuromyelitis optica spectrum disorder (NMOSD) is an immune-mediated inflammatory disorder of
the central nervous system. NMOSD may be associated with other autoimmune disease, including
myasthenia gravis (MG). In most patients with the coexistence of MG and NMOSD, development of
MG and thymectomy preceded the onset of NMOSD. We describe two patients with MG and
NMOSD who had not undergone thymectomy.
