Combined central and peripheral demyelination (CCPD) causes demyelination in both the central and peripheral nervous systems. Anti-neurofascin 155 antibody plays an important pathogenic role in CCPD, but evidence concerning an association between this antibody and CCPD remains inconclusive. Although there have been no reports of precedent optic neuritis developing into CCPD, we herein report a Japanese man in whom optic neuritis recurred four times over nine years and who developed CCPD without positive anti-neurofascin 155 antibody. This case suggests the possibility of developing CCPD after optic nerve neuritis and the existence of an unknown antibody that induces CCPD.
