in campo neuro-AIDS la diagnosi differenziale tra la PML e l'encefalopatia da HIV sembra essere abbastanza definita. tuttavia quando la forma di encefalopatia da virus HIV si manifesta nella variante HIVL (leucoencefalopatia da HIV) molto frequentemente nelle fasi iniziali della malattia neurologica si evidenziano difficoltà di diagnosi differenziale principalmente con la PML. Obiettivi: lo studio si propone di identificare criteri di diagnosi differenziale tra PML e HIVL. Metodi: sono stati valutati i profili neurologici, neuroradiologici e infettivologici di soggetti con diagnosi anatomopatologica di PML e HIVL, senza presenza di coinfezioni cerebrali. Risultati. i soggetti inclusi nello studio sono risultati essere 10 con PML e 9 con HIVL. da un punto di vista clinico la PML ha un esordio subacuto. HIVL sucronico; la PML presenta prevalentemente deficit neurologici di tipo corticale mentre HIVL prevalentemente di tipo sottocorticale. dal punto di vista neuropsicologico la PML presenta deficit prevalentemente fasici, la HIVL deficit mnesici con rallentamento ideo-motorio. radiologicamente la PML presenta una sofferenza focale della sostanza bianca periferica mentre in HIVL vi è un diffuso coinvolgimento della sostanza bianca centrale. la sopravvivenza in PML risulta inferiore rispetto a HIVL. discussione. l'utilizzo dei suddetti criteri clinici nella fase iniziali della patologia cerebrale può costituire un ausilio per un corretto approccio diagnostico ed un tempestivo intervento terapeutico.

Abstract
IN NEURO--AIDS FILED THE DIFFERENTIAL DIAGNOSIS BETWEEN PML AND HIV ENCEPHALOPATHY SEEM QUITE DEFINITE. NEVERTHELESS SOME DIFFICULTIES ARISE, MAINLY AT THE BEGINNING OF THE DISEASE, WHEN HIV ENCEPHALOPATHY MANIFESTS ITSELF AS HIV LEUKOENCEPHALOPATHY (HIVL).
