Tuberculous cerebral vasculitis: retrospective study of 10 cases.

BACKGROUND: Tuberculous cerebral vasculitis is a complication of tuberculous meningitis. This study was undertaken to determine the epidemiological characteristics, context, diagnostic means and outcomes under treatment of tuberculous cerebral vasculitides.
METHODS: All consecutive patients diagnosed with tuberculous cerebral vasculitis were identified from the databases of three Internal Medicine, one Neurology and one Infectious Disease Departments in three suburban Parisian hospitals.
RESULTS: We describe 10 cases: five men and five women (median age 33.5 [range: 27-55] years). Two were infected with the human immunodeficiency virus. Nine patients had tuberculous meningitis, eight with extraneurological involvement. The following manifestations led to the diagnosis: motor deficit, acute confusional state, headaches, involvement, coma and/or seizures. The cerebral vasculitis revealed tuberculosis in three patients, but tuberculosis was already known when vasculitis was diagnosed for the seven others. The cerebral computed-tomography scan showed cerebral infarctions in five patients, hydrocephalus and tuberculomas in four, while magnetic resonance imaging detected infarctions and leptomeningitis in nine patients, pachymeningitis in one, hydrocephalus and tuberculomas in seven. Therapy combined antituberculous agents with oral corticosteroids for all patients, preceded by a methylprednisolone pulse for five patients. Outcome was favorable for nine patients.
CONCLUSION: We described the non-negligible frequency of tuberculous cerebral vasculitides, their clinical manifestations and their potential severity, and the diagnostic and monitoring contributions of magnetic resonance imaging and magnetic resonance angiography.
