Article Abstract
Cryptococcus is a ubiquitous saprophytic fungus that may become pathogenic,particularly in immunosuppressed patients.In the CNS of AIDS patients,the incidence of this fungal infection is 5%of all the opportunistic infections.In this study,we review the MR findings in nine AIDS patients affected by CNS cryptococcosis.All MR studies were performed before and after intravenous administration of a single dose of gadopentetate dimeglumine and again after an additional dose.Autopsy was performed in one case.Magnetic resonance imaging revealed evidence of meningitis or meningoencephalitis,dilated Virchow-Robin spaces,cyst-like structures(gelatinous pseudocysts),and granulomas(cryptococcomas)of the choroid plexuses.The last two findings(pseudocysts and choroidal ependymal granulomas)are relatively specific for cryptococcosis.
