To evaluate the risk factors of tumor-related epilepsy (TRE) and the relationship between TRE and functional/survival outcomes in patients with high-grade glioma (HGG). ⋯ In patients with HGG, preoperative epilepsy is significantly associated with tumor involvement of the frontal lobe, whereas postoperative epilepsy is associated with preoperative epilepsy and dominant hemispheric location. Also, patients with HGG with preoperative epilepsy have better PFS and OS.

We sought to clarify the expression characteristics and prognostic significance of transforming growth factor (TGF)-β3 in cranial meningiomas. ⋯ TGF-β3 expression levels gradually declined with the increase of WHO grade and were lower in recurrent meningiomas than in primary meningiomas. Besides, low TGF-β3 expression was found to predict tumor recurrence and mortality in meningiomas based on univariate analysis.

Pituitary adenomas comprise about 3% of all intracranial tumors in pediatric patients. This study examines the role of stereotactic radiosurgery in the management of pediatric acromegaly or patients with Cushing disease (CD). ⋯ GKRS affords reasonable rates of endocrine remission and tumor control in most pediatric patients with functioning adenomas. The most common post-GKRS complication was hypopituitarism, although this occurred in only a few patients. Given the larger at-risk period for pediatric patients, further study is required to evaluate for delayed recurrences and hypopituitarism.

To define, from a series of surgically treated meningiomas of the posterior fossa with dural attachment above the dural sinuses, the best management of the sinus invasion according to the pattern of venous circulation. ⋯ In patients with posterior fossa meningiomas, we suggest to safety resect the involved sinus segment only when completely occluded. If the sinus lumen is not invaded or the tumor lies on the side of the unique or dominant transverse sinus, it should be preserved. This results in no or negligible risk of venous infarction and rather low recurrence rate.

Double-barrel STA on proximal MCA bypass to treat complex intracranial aneurysms: a reliable high blood flow bypass.
The superficial temporal artery (STA) to proximal middle cerebral artery bypass has been reported before. However, the flow supply capacity of the double-barrel STA to proximal MCA bypass in treating complex intracranial aneurysms has not been well documented. ⋯ When anastomosed to proximal branches, a double-barrel STA to MCA bypass can reliably provide a high blood flow of >100 mL/minute. Combined with aneurysm trapping or parent artery occlusion, this bypass algorithm could be an alternative treatment for complex intracranial aneurysms.
