AQP4-Abs in CSF can be detected in 70% of AQP4-Ab seropositive patients and in none of the AQP4-Ab seronegative patients (Borisow et al. 2018). Cases of clinical NMOSD in which AQP4-Abs was detected in CSF, but not serum have been only rarely reported (Wingerchuk, D. M. et al. 2015). ................
