This study aims to evaluate the outcomes of Gamma Knife stereotactic radiosurgery (SRS) for dural arteriovenous fistulas (dAVFs) in older patients (≥65 years) compared with younger patients (age <65 years). ⋯ SRS achieves obliteration in most older patients with dAVF, with an acceptable rate of complication. There was no increased risk of postradiosurgery complications in the older cohort compared with the younger patients.

Three-dimensional Printed Models in Anatomy Education of the Ventricular System: A Randomized Controlled Study.
The ventricular system is a set of brain cavities without solid tissues and the basis of surgical brain anatomy. To the best of our knowledge, the effect of using 3-dimensional (3D) printed models (3DPMs) on anatomy education of the ventricular system has not been reported. ⋯ Compared with 2DIs, use of 3DPMs and 3DIs could improve the effectiveness of teaching the anatomy of the complex ventricular system. In addition, 3DPMs could markedly increase the interest and enthusiasm of students.

Spinal eosinophilic granulomas (EGs) are uncommon tumors, constituting <1% of all bone tumors. They are mostly seen in the pediatric age group, whereas adult onset is rare. The cervical spine is an infrequent location for EG. The literature is sparse regarding the clinical and management aspects of these lesions, especially in adults. ⋯ Cervical spine EG is rare in adults and usually presents as an osteolytic lesion involving the vertebral body; vertebra plana is very rare. Surgery is typically reserved for patients with severe neurologic deficits and bony instability. The outcome seems good in most cases.

Guidelines may reduce practice variation and optimize patient care. We aimed to study differences in guideline use in the management of traumatic brain injury (TBI) patients and analyze reasons for guideline non-adherence. ⋯ There is substantial variability in the use and implementation of guidelines in neurotrauma centers in Europe. Further research is needed to strengthen the evidence underlying guidelines and to overcome implementation barriers.

Magnetic particle imaging (MPI) is a novel radiation-free tomographic imaging method that provides a background-free, signal attenuation-free, direct quantification of the spatial distribution of superparamagnetic iron-oxide nanoparticles (SPIONs) with high temporal resolution (milliseconds), high spatial resolution (<1 mm), and extreme sensitivity (μmol). The technique is based on nonlinear magnetization of the SPIONs when exposed to an oscillating magnetic field. MPI was first described in 2001. Since then, the technique has been applied to experimental imaging of diseases affecting different organs in the human body. The aim of this paper is to review the potential applications of MPI in the field of neurosurgery. ⋯ MPI is at a preclinical stage. In the future, human-sized MPI scanners, along with the optimal toxicity profile of SPIONs will allow diagnostic applications in neurosurgical diseases.
