Opsoclonus-myoclonus in an HIV-infected child on antiretroviral therapy-possible immune reconstitution inflammatory syndrome

van Toorn R. ; Rabie H. ; Warwick J.M. (2005)


The exact immunopathogenesis and neuroanatomical localization of opsoclonus-myoclonus ataxia syndrome remains unclear. We describe a 1 year 9 month old girl who, shortly after commencement of highly active antiretroviral therapy developed opsoclonus-myoclonus syndrome and subsequently died of disseminated cytomegalovirus infection. We postulate on the etiological factors that may have played a role in the disease pathogenesis of the patient's opsoclonus-myoclonus ataxia. Immune reconstitution inflammatory syndrome was considered the most likely because of the initial CD4 depletion and the onset of symptoms shortly after initiation of antiretroviral therapy. Single photon emission computed tomography (SPECT) proved helpful by localizing the area of dysfunction to the cerebellar vermis. © 2005 European Paediatric Neurology Society.
