NMO antibody in CSF but not blood

Klawtizer EC et al. Neurology 2009
Authors have 3 cases of NMO diagnosed by antibody in CSF not blood. All had rapidly relapsing LETM, none had ON although they were followed for less than two years. Authors speculate on role for CSF testing in instances of suspected NMO with negative serum tests.
