title: [A case of childhood multiple sclerosis presented with meningitis and multiple silent plaques].
abstract: A 13-year-old girl presented herself with right optic neuritis and pleocytosis in the cerebrospinal fluid (CSF) in May 2000. Although her vision gradually improved after steroid therapy, the right optic neuritis relapsed a month later, and MRIs of the brain showed multiple high-signal intensity areas in the white matter of the right frontal and parietal lobes on T2-weighted and FLAIR images. She developed nuchal pain, low-grade fever, and general malaise in January 2002. Mononuclear pleocytosis and an elevation of myelin basic protein level were noted in CSF (33/microliter, 17.7 ng/ml, respectively). In addition to the plaque-like lesions seen in June 2000, MRI at this time showed an increase in the number of plaques in the medulla, pons, bilateral cerebellar peduncles and cerebellum. We thus considered this case as MS presenting with no focal neurological deficits but meningitis and asymptomatic MRI lesions. The past history of relapsed optic neuritis is supportive and compatible with that diagnosis. One might assume that the case belongs to that of relapsed type acute disseminated encephalomyelitis (ADEM). However, the cardinal pictures of the case are those of relapsing optic neuritis and multiple asymptomatic plaques despite clinical remission. Some atypical features like meningitis may predominate in clinical presentations of child MS, since immune response in child may differ from that of adult.
