A peculiar case of intrasacral meningocele and spinal cord tethering is reported. Contents of the intrasacral meningocele and importance of CSF flow analyses with MRI are discussed. Demonstration of CSF flow from the thecal sac to meningocele in the CSF flow MR imaging may be helpful for determining the possibility of meningocele growth. In this report, we have presented the determination of CSF flow as a new surgical indication in this type of cases.

Purely endoscopic endonasal approaches to surgical resection of pediatric suprasellar craniopharyngiomas are uncommonly performed. The aim of the study is to assess the feasibility and to describe the short-term outcomes of endonasal endoscopic approaches for the gross total resection of suprasellar craniopharyngiomas in the pediatric population. ⋯ Complete radiographic resection of pediatric craniopharyngioma can be achieved via a purely endoscopic endonasal approach. In particular, this approach can be performed safely using the "two-nostrils-four-hands" technique with intraoperative neuronavigation. This approach should be highly considered in patients with progressive visual dysfunction. Further studies are needed to characterize the long-term surgical and clinical outcome of pediatric patients treated with this surgical approach.

Review Case Reports
The use of MRI-guided laser-induced thermal ablation for epilepsy.
Epilepsy surgery is constantly researching for new options for patients with refractory epilepsy. MRI-guided laser-induced thermal ablation for epilepsy is an exciting new minimally invasive technology with an emerging use for lesionectomy of a variety of epileptogenic focuses (hypothalamic hamartomas, cortical dysplasias, cortical malformations, tubers) or as a disconnection tool allowing a new option of treatment without the hassles of an open surgery. ⋯ MRI-guided laser-induced thermal ablation for epilepsy is an exciting new minimally invasive technology that finds potential new applications every day in the neurosurgical field. It certainly brings a new perspective on the way we practice epilepsy surgery even though long-term results should be properly collected and analyzed.

Meta Analysis
Histologic grade and extent of resection are associated with survival in pediatric spinal cord ependymomas.
Prognostic factors affecting outcomes in pediatric spinal cord ependymomas are limited. We sought to investigate potential associations between extent of resection and histologic grade on progression-free survival (PFS) and overall survival (OS). ⋯ Among pediatric patients with spinal cord ependymomas, PFS did not differ across histologic grades but was prolonged among patients who underwent GTR. Age, extent of resection, and tumor grade were all significantly associated with survival.
