An intracranial solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm with a high predisposition toward recurrence and metastasis. The definition of SFT was updated according to the 2021 World Health Organization (WHO) classification. Given its rarity and resemblance to meningiomas, SFT is often misdiagnosed and there remains a debate on the treatment for it. We provide a retrospective analysis of SFTs and conclude the outcomes of different treatments. ⋯ GTR and postoperative RT are beneficial for preventing tumor recurrence. Larger studies and long-term follow-up are warranted to further identify the effect of postoperative RT.

Radical resection of complex lesions occupying multiple compartments at the central skull base remains a significant challenge, since surgical outcomes may be compromised by insufficient exposure and inappropriate techniques. However, the efficiency of the maxillary swing approach for these lesions has not been sufficiently evaluated. Careful assessment of lesion characteristics must be performed when selecting the appropriate procedure. ⋯ Our preliminary results suggest that the maxillary swing approach can be an alternative option for managing extreme cases, such as large, extensive, hypervascularized masses with fibrous or calcified consistency, or for recurrent lesions in the central skull base. En bloc resection can be successfully obtained, resulting in long-term local control.

Continuous bedside brain tissue oxygen monitoring is an essential part of managing comatose patients with acute brain injury. Maintenance of adequate brain oxygenation has been established as an important goal in neurocritical care to prevent patients from secondary ischemia. As patients with subarachnoid hemorrhage and traumatic brain injury often require early magnetic resonance imaging, conventionally implanted metal bolts are disadvantageous due to massive artifacts. We hereby report a novel technique of magnetic resonance imaging conditional bedside implantation of a brain tissue oxygenation probe. ⋯ This article describes the feasibility of a novel technique of bedside implantation of a Licox brain tissue oxygenation probe, resulting in a length-adjustable insertion and rigid fixation without metal artifacts in early magnetic resonance imaging.

Optic pathway and hypothalamic gliomas (OPHGs) are challenging to surgically remove owing to their anatomical relationship. We previously reported on surgical treatment outcomes over a 10-year time frame. The purpose of this study was to update the OPHG clinical outcomes for cases in which chemotherapy has become the primary treatment option. The role of surgery was also revisited. ⋯ OPHG management using less invasive operations and chemotherapy as first-line treatment is feasible. Debulking surgery in patients with OPHGs may be considered in cases with cerebrospinal fluid pathway obstruction, progression despite chemotherapy or radiation, and refractory shunt-related ascites.

Patients with posttraumatic hydrocephalus (PTH) have a high incidence of infection after ventriculoperitoneal shunt (VPS). In this study, we investigated different risk factors affecting infection after VPS in PTH patients. ⋯ Age, severe hydrocephalus, hypertension, diabetes, DC, as well as duration of operation for VPS (>60 minutes) were factors that significantly and independently correlated with the incidence of infection after VPS. The receiver operating characteristic curve that we have developed can predict the occurrence of shunt infection.
