A 53-year-old male patient presented with hypopsia of his right eye for 2 months and lower extremities weakness for 8 days. Thoracic MRI demonstrated a lesion at T3 level appearing as hyperintense on T2-weighted images with non-enhancement by contrast medium and demyelinating lesion was considered. Aquaporin-4-Ab was positive and the antibody titer was 1:320 in serum. The diagnosis of neuromyelitis optica spectrum disorders was made. In addition, systemic lupus erythematosus and thymoma coexisted in this patient. After methylprednisolone impact treatment, plasma exchange and immunosuppressive therapy, the right vision and lower extremities weakness of the patient were improved.
