To describe our experience in the resection of gliomas involving the insula and analyze the variables implicated in the management and prognosis of these tumors. ⋯ Surgery for insular gliomas is a complex task that needs to be managed with adequate preoperative and intraoperative assessment in order to achieve maximum safe resection with low morbidity for better functional and oncological outcomes. Adequate anatomical understanding, radiological analysis, awake craniotomy, cortical and subcortical mapping are paramount to pursue this aim.

To evaluate long-term outcomes of surgical resection for congenital brain tumors (CBTs) in infants under one year of age and to identify factors related to survival. ⋯ Surgical resection remains crucial for treating CBTs in infants under one year, yet the aggressive nature of malignant tumors results in suboptimal outcomes regarding prognosis.

Metastasis of WHO grade II or grade II meningiomas are rare. The aim of this study was to investigate their incidence, associated risk factors and treatment course. ⋯ The presence of metastasis contributed to poor outcomes and was related to earlier tumor relapse and major vessel compromise. Subtotal resection should be followed by adjuvant radiotherapy to reduce the risk of metastasis. Further research is warranted to identify circulating or pathologic biomarkers for the early detection of metastasis.

The Matsushima Grade has traditionally been used to evaluate vessel ingrowth from the STA after EDAS for MMD-patients. However, this grading is subjective and prone to measurement variability. Herein, we propose the orbital grading system quantifying leptomeningeal and burr hole-related vessel-ingrowth from the STA and/or MMA to the middle and anterior cerebral arteries post-EDAS in MMD patients. ⋯ The orbital grading system demonstrated agreement in identifying postoperative ischemic events as the Matsushima grade and provides a more practical and objective evaluation of collateral vessel ingrowth after EDAS with and without burr-holes.

Design Retrospective study Objective To observe and measure the safe distance between the uncinate process (UP) and the V2 vertebral artery (VA). ⋯ UP and PT could be seen as the landmarks in the operations of ACDF. The safe space outside UP is about 4mm and more care should be taken when operating on the caudal spine. The safe space outside PT is about 10mm and more care should be taken when operating on the cephalad spine. The safe space for operation from the PT to the ventral side is about 4.5 mm, and more care should be taken when operating on the cephalad side of the cervical spine.
