CT was used to examine six patients with clinically evident atlantoaxial rotary fixation, two patients with torticollis, and six normal subjects who had turned their heads to the side as far as voluntarily possible. The CT appearances of the atlantoaxial complex were identical in all three groups. To differentiate these groups, we propose a functional scan(More)
Vein of Galen malformations may present as congestive heart failure in the neonate and are usually fatal if untreated. Early studies using transcatheter embolization techniques, in a series of 22 patients, had a 50% mortality rate and a 37% incidence of severe mental retardation in survivors. Modifications of embolization techniques and neonatal care have(More)
Treatment options for atypical forms of Landau-Kleffner syndrome (LKS) are not well delineated. Many patients with typical LKS fail to respond to antiepileptic drug treatment, but some benefit from multiple subpial transections (MSTs). The authors report seven patients with autism or autistic epileptiform regression who responded in varying degrees to MSTs(More)
OBJECT Subependymal giant cell astrocytomas (SEGAs) are benign tumors, most commonly associated with tuberous sclerosis complex (TSC). The vast majority of these tumors arise from the lateral ependymal surface adjacent to the foramen of Monro, therefore potentially encroaching on one or both foramina, and resulting in obstructive hydrocephalus that(More)
Low-grade gliomas comprise a heterogeneous group of tumors accounting for 30% to 40% of all primary central nervous system (CNS) neoplasms in the pediatric population. Management of these patients has evolved significantly over the past 2 decades, the present emphasis being on surgery. Adjuvant therapies, such as radiation and/or chemotherapy are generally(More)
A multidisciplinary team approach using a staged transcatheter embolization and neurosurgical protocol was applied to 22 patients with neonatal presentation of vein of Galen malformations over a 12 year period. Aggressive medical therapy was combined with interventions including: ventricular shunting, transcatheter embolization, retrograde transtorcular(More)
Materials and methods Retrospective chart review was conducted on normal pressure hydrocephalus patients who received prospective evaluation at an adult hydrocephalus center and underwent ventriculoperitoneal or ventriculoatrial shunting with either Delta 1 (n = 140) or Orbis Sigma (n = 55) valves between September 1999 and June 2007. All patients received(More)
