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)
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)
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)
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. Among 401 patients admitted with a subarachnoid hemorrhage (SAH), 73 (18%) had a nonaneurysmal perimesencephalic SAH, 28 were not explored(More)
A 55-year-old man with alcoholism required sigmoid resection for complicated diverticulitis. A few weeks after starting parenteral nutrition, he developed multidirectional gaze nystagmus, gait ataxia, and confusion, leading to the diagnosis of Wernicke encephalopathy. Thiamine treatment was started and his symptoms improved, helping to confirm the(More)
A 14-year-old girl, followed in our department for Marfan syndrome, presented with postural headache for a month. Neurological examination was normal. The diagnosis of intracranial hypotension syndrome was suspected. Bilateral subdural hematomas were found on brain magnetic resonance imaging (MRI), and spinal MRI showed large lumbosacral arachnoid(More)
Arterial spin labeling (ASL) is one of the most recent magnetic resonance imaging (MRI) sequences used to assess brain perfusion noninvasively. It can be used in the acute phase of ischemic stroke (IS) to identify ischemic penumbra. In patients in acute phase of IS, thrombus assessment is of major clinical relevance because the presence and location of the(More)
The purpose of the article is to review the CT and MR imaging features of orbital tumors in children. Tumors in children are usually different than those in adults. Clinical symptoms are usually non-specific. Clinical examination combined with US may be sufficient for diagnosis and follow-up of benign and superficial lesions. CT and/or MRI are needed for(More)

A 37-year-old woman, during her second remission of acute myeloid leukemia, presented with severe neck pain and cervico-brachial neuralgia. Investigation revealed a C5-C6 spondylodiscitis. A CT-guided anterior biopsy decompressed the mass, immediately alleviated the symptoms, and isolated a rare yeast: Blastoschizomyces capitatus. To our knowledge, only(More)
