Schwannomas are benign peripheral nerve sheath tumors arising from myelinating Schwann cells. Although macrocystic changes are regularly encountered in schwannoma variants such as vestibular nerve tumors, they are exceedingly rare among spinal neoplasms. ⋯ Macrocystic thoracic schwannomas are exceedingly rare, and lack a comprehensive scheme for clinical classification of their natural history and pathogenesis. We report the 10th case of such a schwannoma, and the first associated systematic review. Although macrocystic thoracic schwannomas are not frequently encountered, accurate diagnosis and appropriate neurosurgical treatment is critical in these vulnerable patients, given the opportunity for excellent functional outcomes following neurosurgical treatment.

Trigeminal neuralgia (TN) is a debilitating condition characterized by sudden, excruciating facial pain due to neurovascular compression of the trigeminal nerve. Stent deployment can change the course of the superior cerebellar artery upwards, possibly releasing the root entry zone of the trigeminal nerve. We developed a novel stent, the Transform stent, for TN treatment, and evaluated its mechanical properties using benchtop and in vitro hemocompatibility tests. ⋯ This study demonstrated the Transform stent as a potential option and paved the way for innovative endovascular approaches for the future TN treatment. Namely, the study confirmed that the characteristics of Transform stents at benchtop and in vitro evaluations may be used as a first step for studies such as in vivo pre- and clinical studies.

Recent years have witnessed a rapidly growing interest in CVJ bony abnormalities, and a qualitative and quantitative analysis of relevant literatures is necessary. This study aims to identify and summarize the published articles related to craniovertebral junction bony abnormalities, to analyze and visualize the current research trends and major contributors. ⋯ This study provides valuable insights into the current research trends and critical contributors in CVJ bony abnormalities, guiding evidence-based decisions and fostering international collaborations to advance knowledge in this field.

The process surrounding application to the national residency matching program changed drastically because of COVID. Virtual interviews, pre-interview zoom socials, and limitations on sub-internships are major changes that applicants worldwide have had to overcome. The available literature does not reflect the impact of major changes to the interview process. Here, we examine the neurosurgery resident cohort from 2021-2023 to investigate differences between United States medical schools pre- and post-COVID. ⋯ Case Western, Johns Hopkins, Mayo Clinic, Vanderbilt, University of Illinois and University of California San Francisco produced the most neurosurgical residents as a percentage of total graduates. There was a statistically significant difference in the post-COVID cohort between medical schools with a home program vs those without. For the top 20 ranked U.S. News medical schools, there was a statistically insignificant increase in the number of graduates matched to neurosurgery CONCLUSIONS: With the data provided, there have not been many significant changes in which medical schools produce the most neurosurgery residents since COVID changes were implemented. The playing field has remained relatively the same in the setting of major changes that were made.

Percutaneous kyphoplasty (PKP) is commonly used to treat severe osteoporotic vertebral compression fractures (OVCFs) by restoring vertebral height. However, its application in mild cases is not frequently discussed. ⋯ PKP is a safe and effective method for treating mild OVCFs, but attention should be paid to the shape and filling effects of cement during surgery to prevent later complications. The developed SFEC scale provides a specific and quantitative standards for evaluating the recovery status after PKP, which need further validations.
