Cerebellar degeneration associated with human immunodeficiency (HIV) infection in the absence of cognitive impairment is exceedingly rare. To date, this association has been the subject of a few reports, representing mostly anecdotal findings. A causative association has been postulated, although significant debate continues over whether or not cerebellar degeneration is actually a complication of HIV infection. We describe an HIV-positive patient with subacute cerebellar syndrome in the absence of any cognitive impairment or alternative cause of cerebellar degeneration.
