  ABSTRACT: Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease caused by reactivation of JC virus in immunocompromised patients. To date, PML with discrete involvement of the pyramidal tract has been described in only two patients. This report describes an additional case with PML showing discrete involvement of the pyramidal tract on T2-weighted images and FLAIR images.
