use of john cunningham virus polymerase chain reaction in the diagnosis of progressive multifocal leucoencephalopathy - a rare presenting manifestation in an hiv-positive patient

Abstract

John Cunningham virus infection is an important cause of progressive multifocal leucoencephalopathy (PML) in the context of advanced human immunodeficiency virus infection. Limited data are available regarding the true incidence of PML as a presenting manifestation of HIV. We report one such case and also highlight the effective use of polymerase chain reaction in confirming its diagnosis.
