| Discussion | Progressive multifocal leukoencephalopathy (PML) MRI: Multifocal T2 hyperintense lesions involving cerebellum and brainstem, progression between 2 months Lab: Serum and CSF JC virus PCR positive Low CD4 count 21% Progressive multifocal leukoencephalopathy (PML) -JC polyomavirus infects oligodendrocytes, causes demyelination in immunocompromised patients -Associated with immunosuppression, often AIDS, organ transplant, cancer, chemotherapy, steroid treatment -Imaging a. Multifocal T2 hyperintense demyelinating plaques involving subcortical white matter, extend to deep white matter b. Gray matter often spared until late stage c. Generally no contrast enhancement or mass effect d. Late: Confluent white matter disease, cystic changes e. Propensity for frontal and parietooccipital region, thalamus, and basal ganglia, may involve brainstem and cerebellum (but, rarely lesions are only in posterior fossa) f. May be solitary, multifocal, or widespread confluent -Highly active antiretrovirus therapy (HAART) reported to improve survival -Differential diagnosis HIV encephalitis, ADEM, acquired CMV, immune reconstitution inflammatory syndrome |
