HIV-Associated Progressive Multifocal Leukoencephalopathy: A Case Study.

Progressive multifocal leukoencephalopathy (PML) is a rare, life-threatening, infectious, lytic, demyelinating disease that results from reactivation of the virulent JC polyomavirus (JCV) "major opportunistic infection" in immunosuppressed individuals.
