Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) and meningioma exhibit similar radiographic features; however, they differ in their prognoses. Preoperative differentiation between them is important for determining the treatment and follow-up plan. The aim of this study was to determine the factors that can be used to differentiate SFT/HPC from meningioma and World Health Organization (WHO) grade I from grade II meningioma. ⋯ Age and myo-inositol level calculated from MRS are useful factors for distinguishing SFT/HPC from meningioma preoperatively.

Stereotactic radiosurgery is a safe and effective technology that can address a variety of neurosurgical conditions, but in many parts of the world, access remains an issue. Although the technology is increasingly available in the United States, Canada, Europe, and parts of Asia, poor access to central nervous system (CNS) imaging and inadequate treatment equipment in other parts of the world limit the availability of radiosurgery as a treatment option. ⋯ Socioeconomic and political forces are relevant to limitations to and opportunities for improving access to care. Here we examine the current barriers to access and propose areas for future efforts to improve global availability of radiosurgery for neurosurgical conditions.

Surgical Approaches in the Treatment of Intracranial Complications of Paranasal Sinus Disease: A Review of the Literature.
Intracranial extension of frontal or ethmoid sinusitis carries a high morbidity and mortality if not treated aggressively. With the emergence of endoscopic sinus surgery (ESS), we questioned whether these approaches have supplanted traditional transcranial procedures for intracranial extension of sinus disease, and whether ESS approaches had a difference in patient outcomes. ⋯ Combined ESS and transcranial approaches achieve definitive control of sinogenic and intracranial disease, whereas either modality alone carries a potential risk for higher morbidity and mortality. The use of ESS alone may have use in the treatment of sinusitis with posterior table erosion prior to intracranial extension.
