[Cerebral vasculitis].

This review focuses on isolated CNS-angiitis and cerebral involvement in systemic vasculitides and collagen vascular diseases. CNS-vasculitis presents with headache, multifocal symptoms, and encephalopathy, respectively. Clinical diagnosis is based on MRI, angiography and both CSF and serum examinations. But neither laboratory nor neuroradiological findings are specific - in all vasculitides with the exception of the Behçet-syndrome a biopsy is necessary before immunosuppressive treatment is started. Therapy of choice is the combination of corticosteroids and cyclophosphamide.
