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.

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.

Continued advancement of the neurological surgery specialty depends on health policy engagement aimed at advocating for and protecting neurosurgeons and their patients. Dr. Ann R. ⋯ This brief historical vignette highlights the qualities of a pioneer advocate in neurosurgery who rose to be a successful leader while overcoming the challenges of practicing in a rural setting and within a historically male-dominated profession. Dr. Stroink's legacy serves as a beacon of inspiration, reminding us that through perseverance and advocacy we can pave the way for a brighter future in neurosurgery and beyond.
