[S-35] Progressive multifocal leukoencephalopathy in the era of disease-modifying therapies

[S-35-3] 進行性多巣性白質脳症におけるMRI画像の特徴と最近の進歩

原田 雅史, 阿部 考志, 坂本 優子 (徳島大学病院 放射線科)

Progressive multifocal leukoencephalopathy (PML) is a rare and severe demyelinating disease of the white matter in the central nervous system caused by JC virus. Multiple sclerosis (MS) treating with disease-modifying therapies (DMT) is newly coming underlying disease of PML. In MS, DMT have recently been shown to reduce the frequency and severity of clinical relapse. Although freedom from disease activity has become the primary aim of the treatment of MS, these DMT increase the risk of PML.
In this symposium, latest information of DMT induced PML, characteristics of MRI in DMT induced PML, development of JC virus DNA detection in the cerebrospinal fluid, and newly aspects of PML will be presented.
