Artificial intelligence (AI) has facilitated the analysis of medical imaging given increased computational capacity and medical data availability in recent years. Although many applications for AI in the imaging of brain tumors have been proposed, their potential clinical impact remains to be explored. A systematic review was performed to examine the role of AI in the analysis of pediatric brain tumor imaging. ⋯ AI methods for analysis of pediatric brain tumor imaging have increased exponentially in recent years. However, adoption of these methods in clinical practice requires further characterization of validity and utility. Implementation of these methods may streamline clinical workflows by improving diagnostic accuracy and automating basic imaging analysis tasks.

This meta-analysis aimed to evaluate the prognostic performance of third ventricular floor bowing (TVFB) as a marker for surgical success in patients undergoing endoscopic third ventriculostomy (ETV). ⋯ This meta-analysis showed that the presence of TVFB was associated with increased ETV success.

Scientometrics is a subfield of bibliometrics that statistically analyzes publications trends. The aim of this initial study was to investigate trends in the 6 major neurosurgical journals from the last 10 years. ⋯ Geographic trends in the diversity of neurosurgical publications sustained its steady increase in most developed counties. Simultaneously, the publication gap between developed and developing countries has remained stagnant.

Internal neurolysis has been proposed as an alternative to microvascular decompression in patients with idiopathic trigeminal neuralgia (TN) in whom neurovascular compression is not confirmed by magnetic resonance imaging (MRI). External neurolysis, which straightens and realigns the trigeminal nerve root axis by dissecting the arachnoid membranes around the nerve, was reported 20 years ago in the context of so-called negative exploration when MRI did not confirm the absence of the offending vessel, but is not currently used. ⋯ Idiopathic TN can be induced by individual variation of the surrounding inner arachnoid membranes supporting the trigeminal nerve root, and the condition cannot be identified by MRI. Intradural external neurolysis may be considered an effective treatment for MRI-negative idiopathic TN.

Intramedullary tumors of the spinal cord account for 2%-4% of all central nervous system tumors. Surgical resection with intraoperative neuromonitoring, although challenging, remains the mainstay of treatment with the goal to prevent neurologic decline. We present a case of an unusual anaplastic glioma of the thoracic spinal cord in a 42-year-old male that spanned 7 vertebral levels and could not be definitively characterized using the 2021 World Health Organization Classification of Central Nervous System Tumors.
