title: Serial proton spectroscopy in a case of adult-onset subacute sclerosing panencephalitis.
abstract: A case of subacute sclerosing panencephalitis in a 27-year-old man was serially evaluated with proton magnetic resonance spectroscopy. Metabolic abnormalities included decreased N-acetylaspartate and elevated choline and myo-inositol in a lesion visible on magnetic resonance imaging and in normal-appearing white matter. Lactate appeared increased within the lesion. Metabolic impairment was persistent after intrathecal interferon-alpha treatment. Spectroscopy pointing to ongoing inflammation, gliosis, and possible membrane turnover was more sensitive than imaging in detecting widespread pathology within the white matter.
