BACKGROUND AND PURPOSE Traumatic axonal injury is a primary brain abnormality in head trauma and is characterized by reduction of fractional anisotropy (FA) on diffusion tensor imaging (DTI). Our hypothesis was that patients with mild traumatic brain injury (TBI) have widespread brain white matter regions of reduced FA involving a variety of fiber bundles(More)
BACKGROUND AND PURPOSE Although it is generally accepted that developmental venous anomalies (DVAs) are benign vascular malformations, over the past years, we have seen patients with symptomatic DVAs. Therefore, we performed a retrospective study and a literature study to review how, when, and why DVAs can become clinically significant. METHODS Charts and(More)
BACKGROUND AND PURPOSE The craniospinal epidural spaces can be categorized into 3 different compartments related to their specific drainage role of the bone and central nervous system, the ventral epidural, dorsal epidural, and lateral epidural groups. We propose this new classification system for dural arteriovenous shunts and compare demographic,(More)
The objective of this study is to present a series of eight pediatric patients (less than 16 years old) with complete spontaneous thrombosis of spontaneous intradural dissecting aneurysms. Since 1989, eight consecutive patients in whom the cerebral aneurysms (four in middle cerebral arteries, one in posterior cerebral artery, three in basilar arteries) were(More)
Intravenous recombinant tissue plasminogen activator for acute ischemic stroke is contraindicated in patients harboring an asymptomatic intracranial vascular malformation, whether it is incidentally discovered at the time of the initial cerebral imaging or previously known. Because thrombolysis is associated with a risk of serious intracerebral hemorrhage,(More)
The clinical manifestations of vascular lesions of the head and neck may be variable (hemorrhagic, ischemic, compressive). Diagnosis often is made at the time of acute presentation, but delayed manifestations, sometimes long after the initial presentation, should not be overlooked. Hemorrhagic manifestations are characterized by epistaxis, corresponding(More)
Routine colonic biopsies allow the detection of alpha-synuclein aggregates in the enteric nervous system (ENS) in living Parkinson's disease (PD) patients. Whether the ENS is affected by alpha-synuclein pathology in multiple system atrophy (MSA) has not been studied yet. The aim of the present research was therefore to analyze colonic biopsies in MSA for(More)
The aim of this study is to investigate perfusion characteristics of brain arteriovenous malformation (AVM) by means of MRI perfusion-weighted imaging (PWI). Forty-three patients with brain AVM were prospectively included and investigated by PWI-MRI. Diagnosis of type of disease was made by angiogram. According to angiographic features, the study group was(More)
We report the follow-up of a previously published case (Forlodou et al. Neuroradiology 38:595–597, 1996) of carotido-cavernous fistulas (CCFs) in a patient presenting with type IV Ehlers–Danlos syndrome (EDS 4) that were successfully treated twice by an endovascular approach. Initial treatment with a detachable balloon was in 1994 for a right CCF, and, 8(More)
OBJECTIVE To report our recent experience in transarterial embolisation of dural arteriovenous malformations (DAVM) using a new liquid embolic agent, Onyx18. PATIENTS AND METHODS 6 patients were enrolled in this series. Clinical presentation was separated into 2 groups: aggressive (n=2), non aggressive (n=4). The DAVM was located at the superior sagittal(More)
