[Central nervous system vasculitides: an update].
Central nervous system (CNS) vasculitides are a heterogeneous group of diseases that can lead to severe disability and death. Given the poor performance of available diagnostic procedures (magnetic resonance imaging, angiography and brain biopsy), the diagnosis of isolated CNS vasculitis is challenging. Differential diagnosis includes secondary CNS vasculitides (infection, cancer, drug exposure or systemic inflammatory disorders) and several non-inflammatory cerebral vasculopathies, such as the reversible cerebral vasoconstriction syndrome. Despite recent advances in neuroradiology and the publication of large retrospective case series, primary angiitis of the CNS remains a heterogeneous and challenging nosological entity. Prospective interdisciplinary studies are necessary to improve our approach to these patients.
