The aim of this study was to report a rare pediatric case of spontaneous spinal epidural hematoma (SSEH) mimicking Guillain-Barré syndrome (GBS), secondary to an epidural arteriovenous malformation (AVM). Furthermore, a case-based update and insight into the entity is attempted. ⋯ Non-traumatic SSEH is rare in the pediatric population. Although vascular malformations are suspected, they are extremely rarely identified histopathologically. This case represents one of the very few reports of pediatric SSEH caused by a histologically proven, purely epidural AVM. High index of clinical suspicion and low threshold for MR can lead to timely diagnosis and prompt treatment with good functional outcome.

Comparative Study
Changes in third ventricular size in pediatric patients undergoing endoscopic third ventriculostomy.
Optimal methods of evaluating radiographic data following endoscopic third ventriculostomy (ETV) are not yet known. This study analyzes imaging parameters, including third ventricular width and cross-sectional area (CSA), in pediatric ETV patients. ⋯ Third ventricular imaging parameters (width and mid-sagittal CSA) exhibited more pronounced responses to ETV than lateral ventricular measurements in pediatric hydrocephalic patients.

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.

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.

The purpose of this study is to compare the surgical and imaging outcome in children who underwent brain tumour surgery with intention of complete tumour resection, prior to and following the start of intra-operative MRI (ioMRI) service. ⋯ Following the advent of ioMRI at our institution, the need for repeat resection within 6 months has been prevented in cases where ioMRI revealed unequivocal evidence of residual tumour.
