Computerized Tomography in Progressive Multifocal Leukoencephalopathy

Computerized Tomography in Progressive Multifocal Leukoencephalopathy Abstract Progressive multifocal leukoencephalopathy (PML) is an uncommon, subacute demyelinating disorder of the central nervous system (CNS) of viral cause, which affects immunologically compromised patients.

Abstract Progressive multifocal leukoencephalopathy (PML) is an uncommon, subacute demyelinating disorder of the central nervous system (CNS) of viral cause, which affects immunologically compromised patients.
