Convergence of the arcuate fasciculus and third branch of the superior longitudinal fasciculus with direct cortical stimulation-induced speech arrest area in the anterior ventral precentral gyrus.
The objective was to identify the correspondence between the anterior terminations of the arcuate fasciculus (AF) and third branch of the superior longitudinal fasciculus (SLF-III) and the intraoperative direct cortical electrical stimulation (DCS)-induced speech arrest area. ⋯ This study supports the key role of the left vPCGa as the speech output node by showing convergence between speech output mapping and anterior AF/SLF-III connectivity in the vPCGa. These findings may contribute to the understanding of speech networks and could have clinical implications in preoperative surgical planning.

Clinical presentation, hemorrhage risk, and outcome in patients with familial cavernous malformations: a pragmatic prospective analysis of 75 patients.
Newly diagnosed patients with a familial cavernous malformation (FCM) and their families are concerned about their future outlook, which is scarcely discussed in the literature. The authors studied a prospective contemporary cohort of patients with FCMs to assess demographics, mode of presentation, prospective risk of hemorrhage and seizures, need for surgery, and functional outcome over an extended interval. ⋯ The authors' findings provide clinically useful information on hemorrhage rate, seizure rate, the likelihood of surgery, and functional outcome. These findings can be helpful to practicing physicians when counseling patients with FCM and their families, who are often apprehensive about their future and well-being.

Observational StudyInterrupted intraarterial selective cooling infusion combined with mechanical thrombectomy in patients with acute ischemic stroke: a prospective, nonrandomized observational cohort study.
The authors aimed to explore the feasibility and efficiency of an interrupted intraarterial selective cooling infusion (IA-SCI) combined with mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS). ⋯ Interrupted IA-SCI for patients with intracranial large vessel occlusion AIS symptoms treated with MT seems to be safe and associated with favorable functional outcomes.

Is brain invasion sufficient as a stand-alone criterion for grading atypical meningioma?
Despite the controversy surrounding brain invasion (BI) as the sole indicator used to diagnose atypical meningioma, this criterion was still incorporated in the 2021 WHO classification scheme. In this study, the authors investigated the reproducibility of this prognostic effect and the impact of BI on the prognosis in otherwise benign meningioma (benign meningioma with BI). ⋯ The findings demonstrate that benign meningioma with BI typically has an intermediate prognosis and can be differentiated from benign meningioma and classical atypical meningioma, which suggests that the importance of the diagnostic effect of BI is insufficiently accounted for in grading of atypical meningioma. Increased emphasis on the presence of BI in patients with atypical meningioma may be helpful in postsurgical decision-making and facilitating improvements in individual therapy.
