title: Serial magnetic resonance imaging (MRI) study of a patient with Balo's concentric sclerosis treated with immunoadsorption plasmapheresis.
abstract: A 28-year-old Japanese woman with Balo's concentric sclerosis developed a rapidly progressive form of encephalopathy. Magnetic resonance imaging (MRI) showed multiple concentric lesions in the central white matter and the cerebellum. The administration of corticosteroid regimen resulted in little benefit. Immunoadsorption plasmapheresis led to a remission within 1 month of onset. Serial MRI study was described here for the first time, which allowed us to observe the development of concentric structures. The observation indicated that, initially, a central core, a round demyelinated area, and surrounding edema appeared around a vessel. Subsequently, concentric demyelinated bands formed simultaneously, not centrifugally, with diminution of the edema. Analysis of cerebrospinal fluid showed elevated levels of interleukin-6 and tumor necrosis factor-alpha. The success of immunoadsorption plasmapheresis therapy in this patient suggests that both humoral demyelinating factors and cell-mediated immunity may be involved in the pathogenesis of this disorder.
