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 Subduroperitoneal drainage (SDPD) is commonly used in the treatment of infantile subdural hematomas (SDHs). Few studies have focused on this technique and most series have included SDHs of various origins in children of different ages. The surgical procedure is not standardized and results achieved using this technique have not been well documented.(More)
BACKGROUND AND PURPOSE MRI signal of a subdural hematoma (SDH) is often regarded as similar to that of an intracerebral hematoma but no precise study has analyzed the evolution of the signal of subdural hematomas. Their dating is however significant, in particular in the child, within the context of the diagnosis of child abuse. The objective of this study(More)
Three cases of epignathus teratoma associated with other midline anomalies are reported. The first case involved Pierre Robin sequence and a bifid tongue. The second case was characterized by two teratomas, a meningoencephalocele, and a cleft lip and nose. The third case had Pierre Robin sequence associated with duplication of the pituitary gland and(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)
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)
OBJECT The dating of inflicted head injuries in infants is a recurrent and difficult problem in the forensic evaluation of child abuse. The dating of hemorrhagic lesions when using magnetic resonance (MR) imaging is delicate because many confusing factors interact. In particular, infants frequently develop subdural hematomas (SDHs), which are generally(More)
OBJECTIVE In some patients with temporal lobe epilepsy, recent MRI studies have revealed several morphological features indicative of discrete hippocampal malformation (HM). Its prevalence is unknown and the relationship between the HM and the origin of seizures has never been investigated. Our purpose is to define the MRI findings of this new entity and to(More)
OBJECTIVES AND DESIGN We performed a prospective study using magnetic resonance imaging (MRI) at regular post-operative intervals in non-irradiated patients with non-functioning pituitary adenomas (NFAs) to assess the frequency of tumoral regrowth and recurrences, in order to define the indications of post-operative radiotherapy. PATIENTS AND METHODS(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)
