Current practice patterns unique to pediatrics may have important implications in recruiting and retaining the next generation of pediatric neurosurgeons.

The site of baclofen's activity when treating dystonia may be at the cortical level, and intraventricular infusion may result in higher baclofen concentrations over the cortex than intrathecal infusion. Additional studies are necessary to determine whether IVB is effective at lower doses than those used with intrathecal baclofen administration.

Fractures through synchondroses are a possibility in the immature spine, in addition to fractures through osseous portions of the vertebral ring, and they create opportunities for misinterpretation of diagnostic imaging. The authors describe 3 examples of Jefferson fractures in young children. All 3 cases featured fractures through an anterior synchondrosis in association with persistence of the posterior synchondrosis or a fracture of the posterior arch. The possibility of a Jefferson fracture should be considered for any child presenting with neck pain, cervical muscle spasm, or torticollis following a head injury, despite a seemingly normal cer...

The differences between boys and girls are clinically insignificant. The critical measurement of whether the C-1 lateral mass in a child could accommodate a 3.5-mm-diameter screw is the width of the lateral mass and its proximity to the vertebral artery. Only 1 of 152 lateral masses studied would not have been able to accommodate a lateral mass screw. This study reemphasizes the importance of a preoperative CT scan of the upper cervical spine to assure safe and effective placement of the instrumentation at this level.

Only 1 case of an infant with a calvarial cavernous hemangioma without intracranial invasion has previously been reported, and that case involved a 4 month old. Although a cavernous hemangioma of the calvaria is extremely rare in the newborn, this condition should be included in the differential diagnosis of calvarial lesions.

Clear cell meningiomas (CCMs) are not uncommon. To the authors' knowledge, 14 cases of pediatric CCM occurring in the spinal canal have been reported. Factors lending resistance to meningioma initiation and invasion are analyzed. This 13-year-old girl presented with pain radiating down her left leg. Admission MR imaging showed an inhomogeneous enhancing intradural-extramedullary mass at the L4-5 level. Resection revealed a CCM, and radiotherapy was subsequently administered. Postoperatively there has been no recurrence in > 2 years. In this paper the authors report a case of CCM and provide a comprehensive literature review on this disease.

These lesions can be incidental neuroimaging findings but may also cause symptoms and necessitate treatment, particularly in children. The authors present their experience with a male infant harboring a large suprasellar-prepontine arachnoid cyst who underwent spontaneous decompression into the ventricular system, as evidenced by a visualized CSF flow jet observed on routine MR imaging.

Clear cell meningiomas (CCMs) are not uncommon. To the authors' knowledge, 14 cases of pediatric CCM occurring in the spinal canal have been reported. Factors lending resistance to meningioma initiation and invasion are analyzed. This 13-year-old girl presented with pain radiating down her left leg. Admission MR imaging showed an inhomogeneous enhancing intradural-extramedullary mass at the L4-5 level. Resection revealed a CCM, and radiotherapy was subsequently administered. Postoperatively there has been no recurrence in > 2 years. In this paper the authors report a case of CCM and provide a comprehensive literature review on this disease.

Wiring techniques have now given way to screw-rod or screw-plate techniques with or without postoperative external immobilization. Although C-2 translaminar screws have been used in these constructs, subaxial translaminar screws have not, to date, been described in either the pediatric or adult patient populations. The authors describe the feasibility of translaminar screw placement in the C-3 lamina. Rigid fixation with translaminar screws offers an alternative to subaxial fixation with lateral mass screws, allowing for formation of biomechanically sound spinal constructs and minimizing poten...

Deterioration of bladder function, risk of recurrence, and loss of lower-extremity function appear to be the most important long-term complications of IC in children with fMMCs. The ongoing NIH-sponsored MOMS may help determine whether children with fMMC are at increased risk of IC development compared with children treated with postnatal MMC closure. Parents seeking fMMC closure should be informed about the possibility of IC formation and the potential clinical consequences. PMID: 19035686 [PubMed - in process] (Source: Journal of neurosurgery.

Alternatively, a transcavum interforniceal route for endoscopic surgery in the third ventricle is suggested, with the rostral lamina and the anterior commissure as important anatomical landmarks. Endoscopic third ventriculostomy and endoscopic colloid cyst resection performed via a transcavum interforniceal route in patients with a coexistent septal cavum is a feasible and safe option.

Placement of a VP shunt helped promote the ascent. However, postnatal myelomeningocele repair in the patients in Group 1 failed to consistently prevent development of symptomatic CM-II. This limited experience suggests that postnatal repair of myelomeningocele can partially reverse the anatomical CM-II, but symptomatic CM-II cannot be prevented in some patients when the repair is performed after 36 weeks' gestation.

An otherwise asymptomatic 6-year-old girl, who presented with headaches and hypertension, underwent a comprehensive workup that revealed extensive meningeal and cerebral artery anastomoses to the left internal carotid artery-itself arising from the origin of the left pulmonary artery. This unique anatomical anomaly, caused by a disturbed pattern of aortic arch regression, resulted in a right-to-left vascular shunt into the pulmonary artery and a disturbance of intracranial artery flow patterns, complicating the management options.

The formation of strong adhesions can embed the catheters so that they cannot be removed without a higher risk of intraventricular hemorrhage. Moreover, the devices could represent a nidus for infection and a risk for formation and enlargement of intraventricular secondary cysts. Neuroendoscopy allows the surgeon safely to reach the ventricular catheters that have been left or lost in the ventricular cavity, and to remove them via a minimally invasive approach.

The formation of strong adhesions can embed the catheters so that they cannot be removed without a higher risk of intraventricular hemorrhage. Moreover, the devices could represent a nidus for infection and a risk for formation and enlargement of intraventricular secondary cysts. Neuroendoscopy allows the surgeon safely to reach the ventricular catheters that have been left or lost in the ventricular cavity, and to remove them via a minimally invasive approach. In this paper, the authors document another application of ventricular endoscopy in th... Journal of neurosurgery.

Because not all patients with good flow on shunt tap underwent surgical shunt exploration, the specificity of this test cannot be determined. Nonetheless, a shunt tap that reveals good flow with a normal opening pressure can be misleading, and management of such cases should be based on clinical judgment.

The rate of ventricular size reduction in response to tumor excision does not have predictive value because ventricular volume is related to tumor volume. It appears that the removal of cerebellar medulloblastoma converts hydrocephalus from obstructive to communicating, which requires surgical treatment if it exceeds a certain level of cerebrospinal fluid volume.

Cervicomedullary decompression is a good first-line option, particularly in children with concordant posterior fossa symptoms. Patients presenting with more severe scoliosis (increasing Cobb angle) or scoliosis that crosses the thoracolumbar junction may benefit from earlier orthopedic involvement and should be monitored regularly for curvature progression after cervicomedullary decompression. In cases in which there is a failure of the syrinx to show improvement after suboccipital decompression, the patients are also more likely to develop curvature progression.

Children with intracranial pathology on acute CT performed more poorly in several cognitive domains when compared with patients whose CT findings were normal or limited to a linear skull fracture. Depending on the presence of preinjury ADHD and concomitant extracranial injury, working memory and visuomotor speed were also diminished in patients whose CT findings revealed complications following MTBI. Computed tomography within 24 hours postinjury appears to be useful for identifying children with an elevated risk for residual neuropsychological changes.
