Spinal schwannoma is a common benign tumor. However, the high recurrence rate and incidence of surgical complications are unsolved problems. ⋯ Spinal schwannoma classification based on a membranous hierarchy provides an intuitive platform for preoperative planning and intraoperative safety. This classification scheme may help surgeons better define surgical goals and anticipate or even avoid complications from resection.

Gliomas are the most common malignant primary brain tumors. Assessment of the tumor volume represents a crucial point in preoperative and postoperative evaluation. ⋯ The considered segmentation tools showed high agreement in preoperative volumetric assessment. Both manual and semi-automated software appear adequate for the postoperative quantification of residual volume. The evaluated automated software is not yet reliable. Automated software considerably reduces the time expenditure.

Vertebral hemangiomas are benign, highly vascular lesions of the vertebra, rarely seen in the pediatric age group. ⋯ Our experience in treating symptomatic pediatric vertebral hemangiomas, along with the long-term follow-up data, suggests that good postoperative results can be achieved with minimal complications in carefully selected patients.
