    AbstractBehcet disease (BD) is a systemic vasculitis which can involve many different organ systems. Neurological involvement (NBD) occurs in 5.3% to 59% of BD patients. The diagnosis is challenging especially in case of inaugural neurological presentation, and is based on a constellation of clinical, laboratory, and neuroimaging findings. NBD can be subdivided into parenchymal NBD through an immune mediated meningoencephalitis with a predilection to the brainstem, basal ganglia, thalamus, cranial nerves, and spinal cord involvement, and extraparenchymal NBD encompassing cerebral veinous thrombosis and intracranial arterial involvement. Brain magnetic resonance shows ill-defined areas of oedema with high signal intensity on T2-FLAIR images, isointense or hypointense in T1-weighted images in the basal ganglia area or in the brainstem, which may extend to the diencephalic structures. Swelling might be noticed. Hemorrhages can be seen, such as contrast enhancement (blood brain barrier disruption). Magnetic resonance venography and computerized tomographic angiography can be used to diagnose extraparenchymal NBD. Treatment of parenchymatous forms is based on glucocorticoids associated with oral immunosuppressants (azathioprine, mycophenolate mofetil or methotrexate) in mild forms, and intravenous cyclophosphamide or infliximab in severe forms. The management of cerebral thrombosis consists of steroids course associated with an oral anticoagulation. An early recognition of this condition is mandatory to initiate adequate therapies in order to improve outcomes and limit the risk of sequelae, relapses, or death. The aim of this review is to summarize a comprehensive review on the various neurological presentations of BD with emphasizes on diagnostic tools, prognosis, and therapeutic issues.Copyright © 2024 Société Nationale Française de Médecine Interne (SNFMI).
