To compare the diagnostic performance of O-(2-18F-fluoroethyl)-L-tyrosine (18F-FET) positron emission tomography (PET) and perfusion-weighted magnetic resonance imaging (PWI) for the diagnosis of progressive or recurrent glioma. ⋯ This pilot study suggests that 18F-FET PET is superior to PWI to diagnose progressive or recurrent glioma.

Case Reports
Bilateral spontaneous regression of vestibular schwannoma in neurofibromatosis type 2: a case report.
Patients with neurofibromatosis type 2 and bilateral vestibular schwannoma (VS) are frequently treated surgically for any tumor progression, and often repeated surgery or radiation treatment is even considered. Some VS progression occurs without the development of new clinical symptoms, or it does not progress in size over many years, even in the absence of any specific treatment. ⋯ We emphasize conservative treatment ("watch and wait") in older patients even with long-term tumor progression without significant compression-related clinical symptoms.

Demographic changes are leading to an aging society with a growing number of patients with cardiovascular diseases, relying on antiplatelet drugs like acetylsalicylic acid (ASA). Although antiplatelet agents are suspected to be protective not only in the cardiologic but in the neurovascular field, the alteration of the coagulating process could have a major impact on the course and outcome after rupture of intracranial aneurysms. ⋯ Patients with continuous ASA treatment were significantly older than patients without ASA, but there was no difference in admission status or bleeding pattern. Outcome was not different in the matched-pair analysis. There was no statistical difference in treatment related-complication rates of microsurgical and endovascular procedures. Therefore, ASA use should not influence treatment decision of the ruptured aneurysm.

To investigate clinical efficacy of and optimal therapeutic strategy for ventricular intracranial pressure monitoring (V-ICPM) in patients with traumatic bifrontal contusions (TBCs). ⋯ Patients with TBCs should be strictly, closely, and dynamically observed by neurosurgery intensive care unit physicians and nurses. Patients should undergo ventricular intracranial pressure probe implantation in a timely manner. V-ICPM can help optimize treatment. Although V-ICPM did not significantly improve the prognosis of patients, it had many other advantages. V-ICPM warrants further clinical research and may be beneficial for patients with TBCs.

To address the feasibility and predictive value of multimodal image-based virtual reality in detecting and assessing features of neurovascular confliction (NVC), particularly regarding the detection of offending vessels, degree of compression exerted on the nerve root, in patients who underwent microvascular decompression for nonlesional trigeminal neuralgia and hemifacial spasm (HFS). ⋯ Multimodal image-based VR using 3D sampling perfection with application-optimized contrasts by using different flip angle evolutions in combination with 3D time-of-flight magnetic resonance angiography sequences proved to be reliable in detecting NVC and in predicting the degree of root compression. The VR image-based simulation correlated well with the real surgical view.
