Review Case Reports
"Intramedullary capillary hemangioma presenting with hydrocephalus and spastic paraparesis in a two-month-old infant".
Intramedullary capillary hemangiomas are rare lesions with only 14 cases reported so far and are found in middle-aged persons. Until now only a single case has been reported in the pediatric population. Ours was the second pediatric case and the youngest of all to be diagnosed with an intramedullary capillary hemangioma. ⋯ Intramedullary capillary hemangiomas are extremely rare lesions in infants but should be kept in mind while treating any patient with the spinal lesion. Further reporting of similar cases will help in understanding the natural history, pathogenesis, and management.

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.

Multicenter Study
Fluorescein sodium in the surgical treatment of recurrent glioblastoma multiforme.
Glioblastoma multiforme (GBM) is the most common primary brain tumor and has a high recurrence rate. Maximizing the extent of resection (EOR) in recurrent GBM has proved to be the cornerstone of neurosurgical retreatment. The development of surgical microscopes fitted with fluorescein-specific filters has facilitated fluorescein-guided microsurgery and the identification of tumor tissue. Use of fluorescein sodium (FL) in primary high-grade glioma resection has shown promising results. Here, we present our experience with FL and the dedicated surgical microscope filter YELLOW 560 nm in 106 patients with recurrent GBM. ⋯ FL and YELLOW 560 nm are readily available methods for fluorescence-guided tumor resection, similar to contrast enhancement in T1-weighted MRI. FL may improve resection in recurrent GBM with minimal risk, and tumor margins are clearly visualized. FL and the YELLOW 560 nm filter are safe and feasible tools for safe maximal resection of recurrent glioblastoma.

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.

Although microvascular decompression (MVD) is the primary treatment for hemifacial spasm (HFS), the postoperative course is variable. This study aimed to develop a prediction model of the outcome of MVD in patients with HFS by investigating influential factors. ⋯ Male sex, mild degree of preoperative spasm, intraoperative indentation on the facial nerve, and postoperative delayed facial palsy were better favorable prognostic factors of MVD in patients with HFS. This novel algorithm may be useful to predict the outcome of MVD in these patients.
