We studied neuropathologic, virologic, and immunobiologic aspects of a patient with acquired rubella developing progressive rubella panencephalitis. There were widespread white matter lesions with active vasculitis. Deposits of IgG were found in histologically normal cerebral vessels, and extracts of brain demonstrated large amounts of rubella-specific antibody. These studies suggest an immunologic component in this form of encephalitis.
