The classification of central nervous system (CNS) tumors has changed greatly. The Central Brain Tumor Registry of the United States (CBTRUS) and other institutions have analyzed the incidence rate and characteristics of primary CNS tumors. However, there are limited studies analyzing the incidence rate and characteristics of CNS tumors in China. To better understand CNS tumors in China, we summarized all primary CNS tumors diagnosed pathologically in a single center from 2003 to 2019. ⋯ Based on this data set, we analyzed various parameters of CNS tumors and found that grade 4 tumors of neuroepithelial tissue were more common in the temporal lobe, which were rarely reported in previous articles.

To compare the surgical and radiographic outcomes of occipitocervical fusion (OCF) with those of atlantoaxial fusion (AAF) in patients with cervical myelopathy caused by retroodontoid pseudotumors (ROPs). ⋯ Although OCF and AAF were similarly effective for cervical myelopathy with ROP, AAF was less invasive, and spinal alignment was better maintained postoperatively in AAF than OCF.

Complex cerebral arteriovenous malformations (AVMs) require a combined therapy of endovascular embolization and microsurgical resection to eliminate the lesion and maximize neurological protection, while a deliberate time interval might contribute to optimal clinical outcomes. The present study aimed to explore the feasibility of this paradigm. ⋯ The deliberately staged combined procedure of embolization and microsurgery might be a safe and efficacious strategy for Spetzler-Martin grade 2-5 AVMs, 4-5 days might be an appropriate staged time interval for ruptured AVMs, although further studies are needed to substantiate these findings.

Pain relief in lumbar disc hernias is a challenging condition. This study retrospectively compared particulate steroids, methylprednisolone acetate (mid-term effective), against betamethasone acetate (long-term effective) on ultrasound-guided caudal epidural injection for lumbar disc herniation. ⋯ No significant difference was observed between betamethasone and methylprednisolone. Both steroid groups showed a substantial improvement in the preoperative pain scores of the patients.
