Angiocentric glioma (AG) is an epileptogenic low grade (World Health Organization grade I) glial tumor with astrocytic and ependymal differentiation, most commonly affecting the pediatric and adolescent population. Despite its infiltrating histological growth kinetics, it is widely accepted that AG has a low potential for aggressive behavior. ⋯ Further research is required to examine the microenvironment and potential for malignant change in this tumor.

Review Case Reports
Encephalopathy of Unknown Origin in a Baclofen Patient: A Case Report and Review of the Literature.
Encephalopathy is reported to have affected 250,000 people in the United States over the last decade, with considerable morbidity and mortality. Baclofen, a gamma-aminobutyric acid-B agonist that acts on the central nervous system, is the drug most widely used to treat spasticity. Baclofen overdose is a potentially deadly condition that can cause encephalopathy and can result from multiple etiologies. Renal disease can contribute to baclofen overdose and encephalopathy, and there are currently no dosing recommendations for patient's on baclofen with renal impairment. ⋯ This case highlights that patients with baclofen overdose can initially appear to have serious brain injury, however, full patient recovery can occur in <72 hours. This case provides additional insight into the guidelines for the treatment and management for unknown cause encephalopathy. This case also highlights the link between renal disease, baclofen, and encephalopathy through a review of the literature.

Review Historical Article
A thoracic surgeon among neurosurgeons: Edward Archibald's forgotten influence on the professionalization of neurosurgery.
Edward Archibald, Professor of Surgery at McGill University (1904-1945), Montreal, Canada, was the foremost thoracic surgeon of his generation. Although instrumental in establishing the American Board of Surgery and in standardizing surgical training, he was also influential as a neurosurgeon. Archibald, an early member invited by Harvey Cushing to join the Society of Neurological Surgeons, helped establish neurosurgery as a distinct, specialized discipline. ⋯ Archibald's personal acquaintance with the principal neurosurgeons of the day, his insight into their personalities, their prominence in the field, and their career paths played a critical role in influencing Penfield to consider relocating to Montreal from Columbia University, despite tempting offers from Boston and Philadelphia. However, it was Archibald's support and mentorship for the creation of an academic center that finally convinced Penfield to move to McGill University. As one of the most influential surgeons of the early 20th century and a founding figure of modern neurosurgery, Archibald is an important part of neurosurgery's legacy.

There is currently no consensus regarding surgical indications for symptomatic sacral perineural cysts. ⋯ To the best of our knowledge, this is the first study to have performed a quantitative analysis of the dynamics of cerebrospinal fluid in sacral perineural cysts using myelographic CT. Sixty-seven percent of patients benefited from surgery; however, our criteria may not be a necessary and sufficient condition for patient selection because 33% did not respond to surgery despite the successful elimination of the check-valve.

Bibliometric analyses are widely used to gauge the scholarly impact of any scientific publication. We conducted a bibliometric analysis of the 100 most influential articles on glioblastoma multiforme (GBM). We searched Scopus using the keywords "Glioblastoma multiforme," "GBM," Glioblastoma," and "Grade IV glioma." A list of the top 100 articles was prepared. ⋯ There were 12 authors who had ≥5 articles in the top 100 citation list. Only 31% of the articles were funded by public and private sector organizations. Our analysis highlights the characteristics of the most influential articles on GBM and provides valuable insight into the research that has been conducted in this field.
