BACKGROUND AND PURPOSE Because of improved visualization of posterior fossa structures with MR imaging, cerebellar malformations are recognized with increasing frequency. Herein we attempt to describe and propose a rational classification of cerebellar malformations. METHODS MR images obtained in 70 patients with cerebellar malformations were(More)
OBJECT The purpose of this study was to describe late neuropathological MRI findings in pediatric severe head injury and to explore the relationship between these lesions and cognitive sequelae. METHODS Thirteen infants with severe head trauma (Glasgow 6) were included in this investigation. Clinical examination, a battery of tests designed to assess(More)
UNLABELLED The mechanisms underlying the hemiconvulsion-hemiplegia-epilepsy syndrome (HHE) remain unclear. The current proposed pathogenic mechanism is a neuronal injury induced by venous thrombosis and/or hypoxia. Previous abnormalities of the brain were suggested as underlying mechanism. MATERIALS AND METHODS We report a patient who presented acutely(More)
BACKGROUND In mental retardation (MR) an aetiological diagnosis is not always obtained despite a detailed history, physical examination and metabolic or genetic investigations. In some of these patients, MRI is recommended and may identify subtle abnormal brain findings. OBJECTIVE We reviewed the cerebral MRI of children with non-specific mental(More)
BACKGROUND Existing methods to predict recovery after severe traumatic brain injury lack accuracy. The aim of this study is to determine the prognostic value of quantitative diffusion tensor imaging (DTI). METHODS In a multicenter study, the authors prospectively enrolled 105 patients who remained comatose at least 7 days after traumatic brain injury.(More)
Data regarding the magnetic resonance imaging (MRI) features in Wernicke-Korsakoff syndrome (WKS) are scarce. WKS usually combines a cerebellar syndrome, oculomotor disorder and confusion. The aim of this study was to determine more precisely the clinical presentation of WKS and the frequency and topography of MRI abnormalities. Furthermore, we try to(More)
The most common cause of subdural hematomas (SDH) in infants is shaken-baby syndrome (SBS). The pathogenesis and natural history of infantile SDH (ISDH) are poorly documented, because in SBS, the date of shaking is usually imprecise and the assault is often repeated. Victims of traffic accidents (TA) form a study group close to experimental conditions,(More)
BACKGROUND AND PURPOSE MR imaging findings of cerebellar cortical dysplasia have been described as a new cerebellar malformation. The purpose of this study was to assess the association of cerebellar cortical dysplasia with other cerebral malformations. METHODS We retrospectively reviewed 46 MR examinations of patients presenting with developmental delay,(More)
BACKGROUND The natural history of posttraumatic meningeal bleeding in infants is poorly documented, and the differences between inflicted head injury (IHI) and accidental trauma (AT) are debated. Autopsy findings have suggested that anoxia also plays a role in bleeding; however, these findings may not reflect what occurs in live trauma patients. PURPOSE(More)
Little documentation of the correlation between MR imaging findings in isolated cerebellar cortical dysplasia (CCD) and its neuropathologic characteristics exists in the recent literature. We documented a postmortem neuropathologic study of a clinically and radiologically well-documented case of CCD in a neonate with severe hypotonia and status epilepticus.(More)
