Surgical management of parasagittal meningiomas (PMs) remains controversial in the literature. The need to pursue a resection as radical as possible and the high risk of venous injuries contribute to making the sinus opening a widely argued choice. This study aimed to analyze factors affecting the risk of recurrence and to assess clinical outcomes of patients who underwent surgical resection of PMs with conservative or aggressive management of the intrasinusal portion. ⋯ Removal of the intrasinusal portion of the tumor using standard procedures is not associated with a higher risk of permanent deficit or worsening of Karnofsky performance scale and reduces the risk of recurrence.

To investigate the incidence rate of primary brain tumors (PBTs) among Palestinian children over a 6-year interval. This study also aimed to identify the predominant histopathologic types identified in these children. ⋯ This is the first national study in Palestine investigating PBTs in children. The crude incidence rate of primary brain tumors among Palestinian children was lower than the incidence rate in many countries around the world. It is recommended that more research be done on the epidemiology and distribution of PBTs in children in Palestine.

Percutaneous vertebroplasty (PVP) is a common method used to treat Kümmell disease. In patients without neurologic symptoms, we sought to evaluate whether using the new spiral injectors instead of the traditional push-rod injectors in PVP can result in improved clinical efficacy for the treatment of Kümmell disease. ⋯ The implementation of both spiral injectors and traditional push-rod injectors in PVP surgery yields effective pain relief, improved function, partially restored vertebral height, and corrected kyphosis in treating Kümmell disease. Compared with the push-rod injector, the spiral injector is highly efficient in restoring vertebral height, correcting kyphosis, and minimizing fluoroscopy use and operation time, but it carries a greater risk of bone cement leakage.

Central neurocytomas (CNs) usually occur in young adults, and the clinical characteristics and surgical outcomes of patients in different age groups may be different. ⋯ CNs in younger adult patients behave differently from those in the older age group. Surgery can halt neurologic deterioration and ensure satisfactory outcomes.

Superficial temporal artery (STA)-middle cerebral artery (MCA) bypass surgery has been widely adopted in treating moyamoya disease (MMD). Geometric variations including high tortuosity and stenosis exist in many cases, but the hemodynamic effects have not been comprehensively evaluated. We aim to evaluate the hemodynamic effects of bypass geometry variations based on patient-specific data. ⋯ High tortuosity and stenosis can significantly change the hemodynamics of STA-MCA bypass, and the optimization of bypass geometry deserves further consideration.
