Abstract

Progressive multifocal leukoencephalopathy (PML) is a demyelination disease caused by opportunistic infection of the ubiquitous, usually nonpathogenic neurotropic papovavirus (JC virus). The virus infects and destroys myelin-producing oligodendrocytes, thereby causing patchy areas of demyelination in the cerebral white matter. It is exclusively a disease of immunosuppressed individuals. We report a case of an immunocompetent child patient with pathologically-proven PML and with a survival over 3 years after diagnosis. Serial follow up of neuroimaging study including brain MRI, MRS, SPECT and PET was obtained. Key Words: Progressive multifocal leukoencephalopathy, Nonimmunocompromised, Longterm-survival
