title: [Cerebral vasculitis with aneurysms caused by varicella-zoster virus infection during AIDS: a new clinicoangiographical syndrome].
abstract: We describe three cases of cerebral angiopathy with aneurysms caused by a meningeal varicella-zoster virus infection occurring during AIDS. The clinical picture was rather stereotyped: severe immunocompromission due to HIV infection, ongoing multifocal cerebrovascular disease with territorial infarcts, lymphocytic meningitis with normal glucose content (two cases) or hypoglycorrhachia (one case), multifocal cerebral vasculopathy with narrowings and aneurysms, healing with or without neurological sequelae after intravenous aciclovir treatment. The diagnosis of varicella-zoster virus-induced angiopathy was ascertained by the positive specific PCR in the CSF in the three cases and by the results of the cerebromeningeal biopsy in one case. Although, varicella-zoster virus is already known as a cause of cerebral angiopathy both in the immunocompetent and the immunocompromised, these three cases are the first ever described of a particular angiopathy with narrowings and ectasias complicating AIDS. The infectious treatable cause and the risk of aggravation without treatment require early active oriented investigations in case of a patient with cerebrovascular disease occurring during HIV infection, including a CSF study with varicella-zoster PCR, to allow specific antiviral treatment. In our three cases, aciclovir intravenous treatment (30mg/kg per day) enabled VZ virus clearing from the CSF and stopped the course of the vasculopathy.
