Meta Analysis
Magnetically Controlled Growing Rod for Early Onset Scoliosis: A Systematic Review and Meta-Analysis.
The goal of the current systematic review and meta-analysis was to explore the utilization of a magnetically controlled growing rod (MCGR) for the treatment of early-onset scoliosis based on eligible studies demonstrating efficacy. ⋯ We demonstrated that MCGR significantly reduced the Cobb angle and thoracic kyphosis while markedly increasing T1-T12 and T1-S1 distances. However, a close comparison of MCGR with CGR reveals more high-quality randomized control trials with a larger sample size and long-term follow-ups are necessary to gather more robust evidence on the efficacy of MCGR for early-onset scoliosis.

Bony anomaly of axis (C2) vertebra is well known. However, expansion of the posterior element is less documented. We describe a case of additional bony ring attached to the posterior spinous process in a 10-year-old male who presented with the complaint of progressive swelling at the upper cervical region. ⋯ Complete surgical excision of the mass was done. Anomalous expansion of the spinous process of the C2 vertebra may remain silent. Surgery may be necessary for cosmetic purposes.

Cost Comparison of Surgical Clipping and Endovascular Coiling of Unruptured Intracranial Aneurysms - A Systematic Review.
Rupture of unruptured intracranial aneurysms (UIA) is the main cause for subarachnoid hemorrhage. UIA are widespread among the population. Advanced technology enables us to diagnose UIAs with increasing reliability and subsequently treat them. There are 2 main treatment options: surgical clipping and endovascular treatment of the aneurysm. This article aims to analyze costs of neurosurgical clipping and the endovascular approach to treat UIA, and to give an overview over the existing literature. ⋯ Due to different definitions of hospital costs and hardly reproducible calculations, comparability of the stated numbers is limited. Besides the economic impact, outcomes must be considered when making a treatment decision. The 2 treatment modalities are not equally suitable in every patient nor for every aneurysm location.

The reliability of fMRI in brain tumor patients: a critical review and meta-analysis.
Formal studies that validated functional magnetic resonance imaging (fMRI) against direct cortical stimulation (DCS) have shown inconsistencies. ⋯ The results from the present analysis of the available reported evidence suggest that fMRI itself (due to neurovascular uncoupling) or analysis of the findings have limitations regarding reliability when validated against DCS. From the existing studies, our results indicate that using fMRI alone for surgical planning could lead to undesirable outcomes.

Review Case Reports
A Case of Primary Sellar Paraganglioma: Immunohistochemistry Resource and Review.
Differential diagnosis of sellar masses includes adenoma, meningioma, craniopharyngioma, and metastasis. Primary paraganglioma is seldom considered. We present a case of this unique pathology, review the relevant literature, and compile a compendium of immunohistochemical characteristics for use as a resource. ⋯ Paraganglioma is a rare but potential differential diagnosis to consider when evaluating sellar masses.
