Progressive Multifocal Leukoencephalopathy Presenting as a Single Mass Lesion

摘要

Progressive multifocal leukoencephalopathy (PML) consisting anatomopatho-logically of multiple foci of white matter demyelination may present both clinically and at CT scanning as a single mass lesion. An additional similar case is reported. As antiviral therapy may prove useful, characteristics of additional examinations including CT scan are described to promote an early diagnosis.
