Most meningiomas are classified as World Health Organization (WHO) grade I. Adjuvant radiation therapy (RT) is commonly recommended for subtotal resections with documented progressive regrowth of lesions with venous sinus involvement. We investigated if recurrence of WHO grade I meningiomas was influenced by adjuvant RT. ⋯ Adjuvant RT does not seem to be a pivotal criterion to reduce the recurrence rate in patients with grade I meningioma, even when venous sinuses are involved.

Poorly understood cranial fluid accumulations are frequently observed after decompressive craniectomy and often termed "external hydrocephalus." These findings are difficult to explain using traditional models of hydrocephalus. ⋯ Closure of the cranial defect with cranioplasty improves cerebral blood flow and CSF pulsatile circulation and is frequently sufficient to resolve the external hydrocephalus.

Bevacizumab plus irinotecan is a new beneficial chemotherapy strategy for patients with malignant glioma. The purpose of this systematic review and meta-analysis was to comprehensively assess the risk of adverse vascular events in adults with malignant glioma treated with bevacizumab plus irinotecan. ⋯ The risk of systemic adverse events was not significantly different between patients with malignant glioma treated with bevacizumab plus irinotecan and the control group. The risks of hematotoxicity, thrombocytopenia, and hypertension were similar in the 2 groups. The risk of thrombosis was higher in patients treated with bevacizumab plus irinotecan. Monitoring for thrombosis and administering anticoagulant therapy as necessary merit promotion for patients with malignant glioma receiving treatment with bevacizumab plus irinotecan.

Review Case Reports
Case Report of Late Type IIIb Endoleak with Willis Covered Stent (WCS) and Literature Review.
We report a case of late type IIIb endoleak with Willis covered stent (WCS) developed 14 months after endovascular paraclinoid aneurysm repair. ⋯ Type IIIb endoleaks can be safely treated by the endovascular positioning of another WCS. Continuous surveillance after endovascular paraclinoid aneurysm repair for intracranial aneurysms is warranted to make ensure the safety of WCS.

Review Case Reports
Spontaneous tumor regression of intracranial solitary fibrous tumor originating from the medulla oblongata: A case report and literature review.
Intracranial solitary fibrous tumor (SFT) is a rare occurrence and involvement of the fourth ventricle rarely reported. Because of its rarity, some characteristics of intracranial SFT seem to still remain uncertain. ⋯ Although the location of the SFT in the fourth ventricle is rare, SFT should be considered as 1 of the differential diagnosis of fourth ventricle tumors. In addition, this case indicates that SFT in the fourth ventricle may regress on occasion spontaneously without a precisely known cause for this spontaneous partial regression.
