Clinical and radiological presentation of cavernomas according to the Zabramski classification.
Cerebral cavernous malformations (CCMs) are a cluster of abnormal vessels of the brain. CCMs have a low risk for intracerebral hemorrhage and appear increasingly often as incidental findings on MRI. Zabramski classification has been used to describe the radiological features of CCMs. How the Zabramski classification associates with the clinical symptoms at presentation and clinical course of the disease is not well established. ⋯ Most CCMs are asymptomatic, incidental findings, in particular, nearly all Zabramski type IV CCMs. If symptoms are present, they are mainly associated with Zabramski type I CCMs and occasionally with Zabramski type II or III CCMs. Although most Zabramski type I CCMs will regress to type II or III and remain asymptomatic, over long-term follow-up, up to one-quarter develop new symptoms.

Evaluation of diversity, equity, and inclusion information on US neurosurgery residency program websites.
The objective of this study was to determine the prevalence of diversity, equity, and inclusion (DEI) information on neurosurgery residency program websites and examine the association between program size, ranking, and DEI information presence. ⋯ Most US neurosurgery residency programs lack DEI information on their websites. Larger programs and those with higher rankings are more likely to include DEI content, particularly standalone statements. Programs meeting DEI criteria tend to have a higher representation of female and Black residents. These findings highlight the need for greater transparency and commitment to DEI in neurosurgery residency programs, ensuring prospective applicants have access to comprehensive DEI information.

Impact of smoking on recurrence rates among wide-neck intracranial aneurysms treated with Woven EndoBridge: a multicenter retrospective study.
Tobacco smoking is among the factors known to significantly augment the risk of untreated intracranial aneurysm (IA) growth and rupture. Smoking appears to have a variable effect on different endovascular treatment modalities. The impact of smoking on the safety, efficacy, and outcomes of Woven EndoBridge (WEB) device use for wide-neck IAs has not been evaluated. This study aimed to investigate the outcomes of WEB devices by smoking status. ⋯ This large-scale study suggests no significant correlation between smoking and the recurrence of IAs treated with the WEB device. Biological studies are warranted to better understand the biological impact of smoking on the growth and rupture of treated IAs.

Noncontrast imaging for the surveillance of treated and untreated meningiomas.
Patients with meningiomas require serial MRI for surveillance of tumor size and growth rate. The cost and resource requirements for contrast-enhanced MRI include intravenous cannulation, the contrast agent, risk of adverse reaction, and the time needed to acquire, review, and report the additional sequences. With repeated doses, gadolinium is known to accumulate in neural tissues. The authors compared the correlation and accuracy of axial T2-weighted imaging (T2WI) sequences alone for assessing tumor growth, dimensions, and dural venous sinus invasion compared with the current clinical practice of assessing both contrast-enhanced T1-weighted imaging (CE-T1WI) and T2WI sequences. ⋯ In patients with treated and untreated meningiomas, unenhanced T2WI can assess tumor dimensions, detect growth, and detect venous invasion with comparable reliability and accuracy to the current clinical practice of using both CE-T1WI and T2WI.
