OBJECTIVE The aim of this study was to analyze the usefulness of preoperative language functional magnetic resonance imaging (fMRI), by correlating fMRI data with intraoperative cortical stimulation results for patients with brain tumors. METHODS Naming and verb generation tasks were used, separately or in combination, for 14 right-handed patients with(More)
INTRODUCTION From January 1998 to December 2002, endovascular treatment (EVT) was used as first intention in all patients with ruptured aneurysms. The objective of this study was to analyze the results of this therapeutic strategy. METHODS Among 401 patients admitted with a subarachnoid hemorrhage (SAH), 73 (18%) had a nonaneurysmal perimesencephalic SAH,(More)
We report the case of a patient with bilateral and symmetrical T2 hyperintensities of the middle cerebellar peduncles. She had a history of left pontine infarction 8 months before. This was attributed to bilateral Wallerian degeneration. MR Spectroscopy showed decreased N-acetyl aspartate/Creatine (NAA/Cr) ratio in the cerebellar peduncles as well as in the(More)
AIM Nowadays endovascular therapy is more and more considered as first choice treatment for ruptured intracranial aneurysms. The aim of this study was to understand the impact that endovascular treatment (EVT), chosen as first therapeutic strategy, has had in the selection of ruptured intracranial aneurysms submitted to surgery at our Institution and what(More)
BACKGROUND Few data are available on the relationship between fluid-attenuated inversion recovery vascular hyperintensities and proximal middle cerebral artery occlusion prognosis. OBJECTIVES To assess a fluid-attenuated inversion recovery vascular hyperintensities score (FVHS) and explore its relationship with recanalization status and clinical outcomes(More)
OBJECTIVE In humans, the inner ear reaches its final configuration and adult size during fetal life. According to the literature, this occurs between 18 and 25 weeks of amenorrhea (WA). The ossification of the otic capsule is believed to arrest any further configuration change. There have, however, been some observations of slight changes in the orientation(More)
BACKGROUND AND PURPOSE In black stroke patients, a particular form of fibromuscular dysplasia (FMD), called atypical FMD (aFMD), is involved in stroke mechanism. The high rate of stroke recurrence under medical treatment leads to propose surgery in such patients. Regarding its location level on the carotid bulb, aFMD is often confused with atherosclerosis(More)
PURPOSE Head-down (HD)-positioning, used in some stroke centers during early ischemic stroke management, is empirical but supported by some physiological findings. It has been shown by nonmagnetic resonance methods that this position can increase cerebral perfusion. This study aimed to investigate magnetic resonance imaging (MRI) ability to measure the(More)
