Over the past decade, stenting of lateral sinus stenosis has been used to treat idiopathic intracranial hypertension. Two types stenoses have identified: extrinsic and intrinsic.The aim this study was report results our use procedure patients with or intrinsic in hypertension.We retrospectively studied clinical, radiological, manometric data from hypertension who were treated at institution between January 2009 2015 by sinus.Data 19 women 2 men. Average body mass index 29 kg/m , median age...

Abstract BACKGROUND: Lateral sinus stenosis is a little-known cause for pulsatile tinnitus (PT). In several small series, stenting has been described as an effective treatment disabling PT linked with this type of stenosis. OBJECTIVES: To describe the clinical, radiological, and manometric characteristics patients treated by lateral Assessment efficacy indication. METHODS: Retrospective study isolated in our institution, between 2009 2015. RESULTS: Fourteen were included study. All them...

In CADASIL (Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy), clinical severity is not related to the total burden of white matter hyperintensities (WMHs), presumably because heterogeneous underlying tissue alterations. We aimed investigate whether WMHs in corpus callosum (WMHCC) are due secondary degeneration severity. evaluated data from 228 patients included an ongoing prospective cohort with available 3-dimensional fluid-attenuated inversion...

Objectives/Hypothesis Because delayed post‐contrast three‐dimensional fluid‐attenuated inversion recovery imaging sequences enable the distinction between utricle and saccule, we raised hypothesis that patients with vestibular atelectasis (VA) could show unilateral collapse of ampullas on imaging. Study Design Retrospective case series. Methods We retrospectively reviewed 200 who underwent 3 T magnetic resonance (MRI) after intravenous administration gadolinium. MRI scans were assessed for...

<h3>BACKGROUND AND PURPOSE:</h3> By studying the evolution of brain volume across life span in male and female patients, we aimed to understand how sex, volume, epidermal growth factor repeat domain mutation, 3 major determinants disability CADASIL, interact driving disease evolution. <h3>MATERIALS METHODS:</h3> We used validated methods model normalized with age patients using nonparametric regression a large, monocentric cohort prospectively collected clinical high-resolution MR imaging...

BACKGROUND: In ischemic cerebral small vessel diseases (cSVD), recurrent stroke is rare (2%–3% per year). Because acute ischemia may not always lead to in cSVD due the size of lesions, reliably reflect activity or risk further clinical worsening, as both incident lacunes and incidental diffusion-weighted imaging–positive lesions can occur without symptoms. We aimed evaluate total by measuring incidence magnetic resonance imaging (MRI)–proven ischemia, independent presence symptoms a large...

Objective Intravascular lymphoma is a rare subtype of B‐cell characterized by clonal proliferation restricted to the lumen small vessels. Over 50% patients exhibit central nervous system (CNS) involvement, but diagnosis often delayed due lack distinctive features. We aimed identify key phenotypic features for early intravascular with CNS involvement through an in‐depth cohort study. Methods built up multicenter retrospective 17 recruited in collaboration French Expert Network Oculo‐Cerebral...

A 19-year-old man presented with a 1.5-month history of hypokinetic dysarthria, slight hypokinesia, and micrographia. Brain MRI showed fluid-attenuated inversion recovery (FLAIR) (figure 1) T2 2) hyperintensities in the medulla oblongata mesencephalon. Copper tests reported high 24-hour urinary copper excretion, low serum copper, ceruloplasmin, exchangeable copper. Kayser-Fleischer rings were present. ATP7B genetic analysis confirmed diagnosis Wilson disease (WD) presence 2 mutations.
