Brush Sign on pre-treatment imaging is associated with good functional outcome in stroke patients treated with mechanical thrombectomy: A prospective monocentric study.

Background: The Brush Sign (BrS) is a radiological biomarker (MRI) showing signal decrease of subependymal and deep medullary veins on paramagnetic-sensitive magnetic resonance sequences. Previous studies have shown controversial results regarding the prognostic value of BrS. We aimed to assess whether BrS on T2*-weighted sequences could predict functional prognosis in patients treated with mechanical thrombectomy (MT).

Criteria improving multiple sclerosis diagnosis at the first MRI.

The introduction of the McDonald criteria has enabled earlier diagnosis of multiple sclerosis (MS). However, even with the 2010 revised criteria, nearly 50% of patients remain classified as "possible MS" following the first MRI. The present study aimed to demonstrate that time to MS diagnosis could be shorter than 2010 revised criteria, and established after a single early MRI in most patients with the association of the symptomatic lesion and at least one suggestive asymptomatic lesion.

Acute disseminated encephalomyelitis in two renal transplant patients: is there a role for Epstein-Barr virus reactivation?

Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system, usually occurring after a vaccination or infectious disease. It has been exceptionally described in transplanted patients. The pathophysiology remains incompletely understood.

[NeuroBehcet disease with corpus callosum involvement].

Introduction: Behçet's disease is a multi-system vascular-inflammatory disease with possible involvement of the central nervous system. Lesions of the corpus callosum on MRI have been rarely reported in this disease.

Case Report: A 47-year-old woman was admitted for a sudden right hemiplegia and confusion revealing a Behcet's disease.
