Subcortical DNET in a Patient With an Enzymatic Deficiency: A Rare Case and Review of the Literature.

Purpose: This case report describes a toddler with a medical history of biotinidase deficiency who presented with atypical seizures due to a brain tumor.

Methods: This is a case report.

Results: Electroencephalogram revealed a frontal lobe mass, with magnetic resonance imaging confirmation of a mass extending from the frontal lobe into the genu and anterior corpus callosum.

The simple sacral dimple: diagnostic yield of ultrasound in neonates.

Background: Although spinal cord tethering is known to be associated with certain clinical syndromes and cutaneous stigmata, its incidence in healthy infants with simple sacral dimples has not been thoroughly evaluated.

Objective: Our objective was to determine the frequency of tethered cord in otherwise healthy patients with simple sacral dimples.

Materials And Methods: We reviewed the lumbar spine US reports of all healthy neonates referred for a simple sacral dimple during a 12-year period at two children's hospitals.

Intraoperative neurophysiologic monitoring in 80 patients with Chiari I malformation: role of duraplasty.

Neurophysiologic intraoperative monitoring of the brainstem auditory evoked potentials (BAEPs) is a widely used method to assess the functional integrity of the central auditory system during surgery involving the brainstem or the cranial nerves. The purpose of this study is to describe our experience with neurophysiologic intraoperative monitoring of BAEPs during posterior fossa decompression (PFD) surgery for the management of Chiari I malformation. Although suboccipital craniectomy is the standard surgical technique applied in all cases undergoing PFD, the role of dural patch grafting (duraplasty) remains controversial.

Abdominal complications of ventriculoperitoneal shunts in children.

Ventricular peritoneal cerebrospinal fluid shunting has become a common pediatric neurosurgical procedure over the last 40 years. While invaluable for these patients, shunts are prone to complications, especially in children. Abdominal complications are often secondary to infection and its complications, and may be difficult to recognize in these medically complex children.

Spontaneous regression of a diffuse brainstem lesion in the neonate. Report of two cases and review of the literature.

The authors present two cases of diffuse brainstem lesions that regressed without treatment. Two newborns presented with cranial nerve palsies and limb weakness at birth. Magnetic resonance (MR) images obtained in the 1st week of life revealed a large, expansive pontomedullary lesion in each patient.
