Posterior cranial fossa (PCF) hemangioblastomas are benign, highly vascularized, and well-differentiated tumors with well-described histopathologic features. Although relatively rare, this tumor is the most prevalent primary tumor of the cerebellum in adults. ⋯ The literature of adult PCF hemangioblastomas is limited and general surgical experience with such tumors is scarce because of their rarity. Rates of postoperative complications and mortality remain higher than expected. However, prognosis and surgical outcomes are generally favorable. Nevertheless, surgery of adult PCF hemangioblastomas is a demanding and challenging task.

Randomized Controlled Trial Comparative Study
Comparison of clinical and radiographic outcomes for posterior fossa decompression with and without duraplasty for treatment of pediatric Chiari I malformation: a prospective study.
The aim of this study was to prospectively compare the radiographic and clinical outcomes between the posterior fossa decompression (PFD) and PFD with duraplasty (PFDD) procedures in adolescent patients with Chiari malformation type I (CMI). ⋯ Compared with the more aggressive decompression with duraplasty, PFD without duraplasty produces comparable radiologic and clinical outcomes and is associated with a lower risk of complications.

Multicenter Study
Effect of Smoking Status on Successful Arthrodesis, Clinical Outcome, and Complications After Anterior Lumbar Interbody Fusion (ALIF).
Anterior lumbar interbody fusion (ALIF) is a surgical technique indicated for the treatment of several lumbar pathologies. Smoking has been suggested as a possible cause of reduced fusion rates after ALIF, although the literature regarding the impact of smoking status on lumbar spine surgery is not well established. This study aims to assess the impact of perioperative smoking status on the rates of perioperative complications, fusion, and adverse clinical outcomes in patients undergoing ALIF surgery. ⋯ The rate of successful fusion after ALIF surgery was found to be significantly lower for smokers compared with nonsmokers. No significant association was found between smoking status and other perioperative complications or adverse clinical outcomes.

Meta Analysis
Association of SOX17 Gene Polymorphisms and Intracranial Aneurysm: A Case-Control Study and Meta-Analysis.
Genome-wide association studies have revealed an association between SRY-box 17 (SOX17) gene and intracranial aneurysm (IA) formation. However, results were mainly derived from European and Japanese populations. We investigated the association between SOX17 gene polymorphisms and IA in a homogeneous Korean population. We performed a meta-analysis to assess these results in East-Asian populations. ⋯ Identification of genetic variants located near SOX17 is likely to be clinically significant for IA formation. rs10958409 and rs9298506 may increase risk of IA in East-Asian populations. Our findings may help in the identification of IA pathogenesis.

Suboccipital decompressive craniectomy (SDC) for cerebellar infarction has been traditionally performed with minimal high-quality evidence. The aim of this systematic review and meta-analysis is to investigate the impact of SDC on functional outcomes, mortality, and adverse events in patients with cerebellar infarcts. ⋯ The best available evidence for SDC is based on retrospective observational studies. SDC for cerebellar infarction is associated with better outcomes compared with decompressive surgery for hemispheric infarctions. Lack of standardized reporting methods for SDC is a considerable drawback to the development of a better understanding of the impact of this surgery on patient outcomes.
