The pathophysiology of vestibular schwannoma (VS) pseudoprogression after Gamma Knife radiosurgery (GKRS) remains unclear. Radiological features in pretreatment magnetic resonance images may help predict VS pseudoprogression. This study used VS radiological features quantified using an automated segmentation algorithm to predict pseudoprogression after GKRS treatment. ⋯ Pseudoprogression is more likely to occur in solid VS compared with cystic VS. Quantitative radiological features in pretreatment magnetic resonance images were associated with pseudoprogression after GKRS. In T2W/CET1W images, solid VS with a lower mean tumor SI and cystic VS with a lower mean SI of cystic component were more likely to have pseudoprogression after GKRS. These radiological features can help predict the likelihood of pseudoprogression after GKRS.

This multicenter study aimed to assess the safety and efficacy of the Woven EndoBridge (WEB) device for treating unruptured wide-neck intracranial bifurcation aneurysms (WIBAs) with short-, mid-, and long-term follow-ups (FUPs). ⋯ The WEB device was safe and effective for treating unruptured WIBAs, both in short-term and long-term FUPs.

Military-civilian partnerships have built the foundation for US neurosurgery as we see it today. Each conflict throughout history has led to expansion within the field of neurosurgery, benefiting civilian patients and those in uniform. Despite the field's growth during wartime, military neurosurgical case volume declines during peacetime, and as a result, important knowledge gained is at risk of being lost. ⋯ In addition to providing a history of military-civilian partnerships in neurosurgery, we have analyzed the declining case volume trends at a single military treatment facility with neurosurgical capabilities. We compared the case volume of a military neurosurgeon at a civilian partnered location with their previous volume at a military treatment facility and analyzed current trends in wartime readiness by Neurosurgery Knowledge, Skills and Abilities metrics. We believe that military civilian partnerships hold the key to scaffolding the experience to maintain the wartime readiness in the military neurosurgical community.
