This study aims to evaluate quantitatively the mechanical properties of meningiomas and their correlation with the qualitative surgeon's assessment of consistency, as well as comparing the capability to predict tumor consistency of fractional anisotropy values calculated from the diffusion tensor imaging and T1/T2 signal intensities. ⋯ Qualitative surgeon's assessment was in accordance with measured mechanical properties. Fractional anisotropy value was not an independent predictor for tumor consistency and was not correlated with the mechanical tests results. T1/T2 assessment was correlated with mechanical properties and it can be used to discriminate very hard or soft tumors.

Review Meta Analysis Comparative Study
Hybrid Decompression Technique versus Anterior Cervical Corpectomy and Fusion for Treating Multilevel Cervical Spondylotic Myelopathy: Which One Is Better?
The hybrid decompression technique (corpectomy combined with discectomy) and anterior cervical corpectomy with fusion (ACCF) both provide good neurological recovery and disease stabilization for the treatment of multilevel cervical spondylotic myelopathy (CSM). However, no single study has been large enough to determine definitively which one is superior for this condition. ⋯ Based on this meta-analysis, both the hybrid technique and ACCF can achieve good results for CSM. However, the hybrid technique is associated with significantly less blood loss, complications, and a higher fusion rate than ACCF.

Observational Study
Reference ranges for head circumference in Ethiopian children 0 - 2 years of age.
Head circumference (HC) charts are important for early detection of hydrocephalus during childhood. In low-income countries where population-based HC charts are rarely available, hydrocephalus occurs more commonly than in developed countries, and is usually not diagnosed early enough to prevent severe brain damage. This applies to Ethiopia as well. The World Health Organization (WHO) has provided standard HC charts advocated for global use, but recent studies cast doubts whether these charts are equally applicable in various populations. The aim of the study was therefore to establish reference ranges for early childhood HC in Ethiopia. ⋯ Ethiopian HC reference ranges for children from birth to 24 months of age were found to differ significantly from those established by WHO and should correspondingly be considered as the first choice for screening for hydrocephalus in that population.

Surgical Management of Giant Intracranial Arteriovenous Malformations: A Single Center Experience over 32 years.
Treatment of giant intracranial arteriovenous malformations (gAVMs) is a formidable challenge for neurosurgeons and carries significant morbidity and mortality rates for patients compared with smaller AVMs. In this study, we reviewed the treatments, angiographic results, and clinical outcomes in 64 patients with gAVMs who were treated at Henry Ford Hospital between 1980 and 2012. ⋯ Treatment of gAVMs carries significant morbidity and mortality; however, good outcomes are attainable with a multimodal treatment approach in carefully selected patients.

Extraventricular intraparenchymal choroid plexus tumors (CPTs) in the cerebral hemisphere are extremely rare. The aim of this study was to investigate the clinical characteristics, radiologic findings, and surgical outcomes of this atypical type of CPT. ⋯ In contrast to typical lesions, extraventricular intraparenchymal CPTs in the cerebral hemisphere are rarely associated with hydrocephalus. Magnetic resonance imaging features are key in preoperative diagnosis; nevertheless, it is difficult to distinguish this atypical type of CPT from other lesions. Surgical removal of the tumor is safe and efficacious.
