ResumoIntroduction The spectrum of neurologic disorders associated with HIV infection is very broad, resulting from direct virus invasion, opportunistic infections, malignancies and toxic effects of drugs. Methods Among a large cohort of ataxia patients (N = 1050) evaluated between 2008 and 2017, we detected four patients with HIV-infection who developed a pure progressive cerebellar ataxia syndrome combined with cerebellar atrophy. Results Adverse drug effects, opportunistic infections and malignancies as well as immune-reconstitution syndrome were ruled out based on history and laboratory data. The exact pathophysiological mechanisms of ataxia in HIV patients is not very clear, but seems to be immune-mediated or a direct neurotoxic virus effect leading to apoptosis of Purkinje and granular cells. Conclusion HIV infection should be investigated in adult patients with undetermined sporadic progressive pure ataxia with cerebellar atrophy.
