OBJECT Cerebellar mutism syndrome (CMS) is a unique postoperative syndrome typically arising 1 to 2 days after resection of a midline posterior fossa tumor; it consists of diminished speech progressing to mutism, emotional lability, hypotonia, and ataxia. Most descriptions have been limited to small institutional series using a retrospective chart review(More)
Intracranial hemorrhage (ICH) from an intracranial aneurysm or arteriovenous malformation is a grave complication of pregnancy and is responsible for 5 to 12% of all maternal deaths. We critically analyzed 154 cases of verified ICH during pregnancy from an identified intracranial lesion, including 2 patients treated at our institution and 152 cases(More)
OBJECTIVE Abusive head injuries among infants (shaken infant or shaken impact syndrome) represent a devastating form of child abuse; an effective prevention program that reduces the incidence of abusive head injuries could save both lives and the costs of caring for victims. We wished to determine whether a comprehensive, regional, hospital-based, parent(More)
PURPOSE The lack of a well-recognized normal size criterion for the choroid plexus makes small or diffuse choroid plexus pathologies difficult to recognize. The purpose of this study was to determine the normal size of the choroid plexus in the pediatric population utilizing magnetic resonance imaging (MR) and ultrasound (US). As volume measurement across(More)
OBJECT The authors conducted a study to determine correlations between clinical syndromes and early magnetic resonance (MR) imaging-documented findings in children with spinal cord injury without radiographic abnormality (SCIWORA). METHODS The authors retrospectively reviewed the records obtained in 20 patients who presented with SCIWORA to the Children's(More)
The authors review current views on of the embryogenesis of the neural tube defects (NTDs) myelomeningocele and anencephaly. In this context, the following four approaches to the study of NTDs are discussed: normal morphogenesis and timing of early human neural development from conception to the ascent of the conus medullaris; mechanical and molecular(More)
OBJECT The mean level of the conus medullaris (CM) has been estimated to lie opposite the L1/2 disc space in several previous studies using ultrasound, CT myelography, and magnetic resonance (MR) imaging, but these studies have been limited in examining only the lumbar spine and including patients being evaluated for back pain and sciatica (creating a(More)
OBJECT Tectal plate gliomas are generally low-grade astrocytomas with favorable prognosis, and observation of the lesion and management of hydrocephalus remain the mainstay of treatment. METHODS A cohort of patients with tectal plate gliomas at 2 academic institutions was retrospectively reviewed. RESULTS Forty-four patients with a mean age of 10.2(More)
If meningomyelocele is indeed a progressive intrauterine process, then early delivery or possibly intrauterine repair of meningomyelocele becomes an issue. Utilizing the delayed splotch (Spd) mouse, a genetically transmitted neural tube defect model, we looked for evidence of abnormalities of neural tissue exposed to amniotic fluid. Affected embryonic and(More)
Much confusion still exists concerning the pathological definitions and clinical significance of double spinal cord malformations. Traditional terms used to describe the two main forms of these rare malformations, diastematomyelia and diplomyelia, add to the confusion by their inconsistent usage, ambiguities, and implications of their dissimilar(More)
