A Case of Progressive Multifocal Leukoencephalopathy in a Patient with Acquired Immune Deficiency Syndrome

ABSTRACT

In Korea, as the prevalence of acquired immune deficiency syndrome (AIDS) increases, various opportunistic infections are becoming a problem. Progressive multifocal leukoencephalopathy (PML) is postulated to be associated with impaired cellular immunity and can be more frequently encountered these days primarily due to increasing incidence of AIDS. Neurologic deficits and brain imaging study together strongly suggest PML, but confirmatory diagnosis can be made only by cerebrospinal fluid study or tissue biopsy. In Korea few cases of confirmed PML in AIDS patients have been reported, and herein we offer our experience of a case of PML who underwent brain biopsy for confirmative diagnosis.
