OBJECTIVE Tuberous sclerosis complex (TSC) is a genetic disorder characterized by the formation of hamartomas in multiple organs. Five to 15% of affected individuals display subependymal giant cell astrocytomas, which can lead to substantial neurological and postoperative morbidity due to the production of hydrocephalus, mass effect, and their typical(More)
OBJECTIVE To report long-term efficacy and safety data for everolimus for the treatment of subependymal giant cell astrocytoma (SEGA) in patients with tuberous sclerosis complex (TSC). METHODS This was an open-label extension phase of a prospective, phase 1-2 trial (NCT00411619) in patients ≥3 years of age with SEGA associated with TSC. Patients received(More)
OBJECTIVE To analyze the cumulative efficacy and safety of everolimus in treating subependymal giant cell astrocytomas (SEGA) associated with tuberous sclerosis complex (TSC) from an open-label phase II study (NCT00411619). Updated data became available from the conclusion of the extension phase and are presented in this ≥5-year analysis. METHODS Patients(More)
BACKGROUND AND PURPOSE The relationship between enlarged subarachnoid spaces and subdural collections is poorly understood and creates challenges for clinicians investigating the etiology of subdural collections. The purpose of this study was to determine the prevalence of subdural collections on cross sectional imaging in children with macrocephaly(More)
In this research, we developed a robust two-layer classifier that can accurately classify normal hearing (NH) from hearing impaired (HI) infants with congenital sensori-neural hearing loss (SNHL) based on their Magnetic Resonance (MR) images. Unlike traditional methods that examine the intensity of each single voxel, we extracted high-level features to(More)
OBJECTIVE The AAP recommends that a follow-up skeletal survey be obtained for all children < 24 months of age who are strongly suspected to be victims of abuse. The objective of the current study was to evaluate the utility of a follow-up skeletal survey in suspected child physical abuse evaluations when the initial skeletal survey is normal. METHODS A(More)
INTRODUCTION The purpose of this study was to determine the diagnostic accuracy of synthetic MR sequences generated through post-acquisition processing of a single sequence measuring inherent R1, R2, and PD tissue properties compared with sequences acquired conventionally as part of a routine clinical pediatric brain MR exam. METHODS Thirty-two patients(More)
BACKGROUND Reduced field of view diffusion-weighted imaging (rFOV DWI) is a more recently described technique in the evaluation of spine pathology. In adults, this technique has been shown to increase clinician confidence in identification of diffusion restricting lesions. PURPOSE In this study, we evaluate the image quality and diagnostic confidence of(More)
The primary objectives of this study were to determine the prevalence of nonconvulsive seizures and nonconvulsive status epilepticus in patients with abusive head trauma who underwent electroencephalography (EEG) monitoring and to describe predictive factors for this population. Children with a diagnosis of abusive head trauma were studied retrospectively(More)
We present a case of epignathus (oral teratoma) with midline intracranial associated malformations. This is a rare report of epignathus diagnosed in utero with fetal MRI description of these midline brain malformations, including duplication of the pituitary gland. This case is an example of how these intracranial findings led to the correct diagnosis of a(More)
