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)
The clinical and pathological characteristics of supratentorial ependymomas (STE) in children are not well identified in the literature, because most series deal with ependymomas regardless of their location or the age of the patient. As a result, the pathological description of the disorder is still debated. We therefore reviewed our cases of children(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)
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)
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)
Neonatal traumatic head injuries (NTHI) can be life-threatening and require aggressive treatment. The indications, techniques, and results of brain decompression are not well defined in the literature. We studied prospectively cases of NTHI with intracranial traumatic lesions; skull fractures without underlying lesions were not included. We treated 17 cases(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)
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)
