[Progressive cytomegalovirus encephalitis in successful ganciclovir therapy of cytomegalovirus retinitis in an AIDS patient].

We describe a case of an HIV-infected intravenous drug-abuser who died of progressive cytomegalovirus encephalitis despite successful treatment of cytomegalovirus retinitis with ganciclovir. On autopsy, complete remission of retinitis and widespread cytomegalovirus-encephalitis could be demonstrated. Therapeutic failure therefore seems attributable to insufficient CNS-distribution of ganciclovir rather than to ganciclovir-resistant cytomegalovirus strains.
