Cortical vein thrombosis without sinus involvement is rarely diagnosed, although it may commonly be overlooked. We report four cases of cerebral venous thrombosis limited to the cortical veins. The diagnosis was made on surgical intervention in one patient and by angiography in three patients. Together with a survey of the published cases, the clinical and(More)
Fifteen patients were observed between 1987 and 1990: there were six with angiographically confirmed vertebral artery dissection, and 9 with carotid artery dissection. Results showed concordance of MRI and angiographic findings, in all cases but one. The dissected portion consistently showed a semilunar hyperintensity narrowing the residual eccentric signal(More)
OBJECTIVES Our purpose was to know more about the symptoms and clinical and radiological outcome of spontaneous dissections of the internal carotid artery in a retrospective study of 68 patients aged 20 to 71 (mean 46). METHODS The diagnosis of dissection was based on angiographic findings. Nine percent of patients had minor symptoms such as a subjective(More)
OBJECTIVES To determine whether migraine is a risk factor for ischaemic stroke. DESIGN A case-control study. SETTING Two hospitals in Paris. SUBJECTS 212 patients with stroke (137 men and 75 women) and 212 controls matched for sex, age (to within five years), and history of hypertension. MAIN OUTCOME MEASURES Ischaemic stroke, confirmed by brain(More)
OBJECTIVE To assess the sensitivity of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) in the diagnosis and the follow-up of cerebral venous thrombosis (CVT). To describe MRI and MRA features in CVT. MATERIAL AND METHODS The clinical and neuroradiological studies of 20 patients with proven CVT were reviewed. All patients(More)
Deep cerebral venous thrombosis (DCVT) is a rare, potentially fatal disease. We carried out a retrospective analysis of eight patients presenting with DCVT, using CT and MRI data. Digital subtraction angiography (DSA), MR angiography (MRA) (2D phase-contrast), and angiography were performed in four, four and two patients, respectively. Direct (venous(More)
BACKGROUND Symptomatic intracranial atherothrombotic stenoses (ICAS) are associated with high rates of cerebrovascular ischemic events. OBJECTIVE To conduct a prospective multicenter study to evaluate the natural history of ICAS and, in those patients refractory to medical treatment, the outcomes associated with intracranial angioplasty. METHODS(More)
Cerebellar syndromes and radiologic cerebellar atrophy after hyperpyrexia have occasionally been reported, mostly in neuroleptic malignant syndromes, but neuropathologic studies are extremely rare. We studied 3 patients (a 74-year-old woman, a 63-year-old man, and an 80-year-old man) who had heat stroke during heat waves in France. One patient had(More)
Moyamoya is a cerebrovascular angiopathy characterized by a progressive stenosis of the terminal part of the intracranial carotid arteries and the compensatory development of abnormal and fragile collateral vessels, also called moyamoya vessels, leading to ischemic and hemorrhagic stroke. Moyamoya angiopathy can either be the sole manifestation of the(More)
