Intraneural perineurioma is a rare peripheral nerve sheath tumor characterized by localized proliferation of perineurial cells. The literature consists predominantly of case reports and institutional series, with inconsistent and confusing nomenclature. We present a pooled analysis of all reported cases of intraneural perineurioma in the literature. ⋯ Intraneural perineurioma represents a benign focal lesion presenting with weakness and atrophy affecting adolescents and young adults. Most cases are managed nonoperatively and surgical treatment strategies are varied.

Randomized Controlled Trial
Efficacy and Safety of a Thrombin-Containing Collagen-based Haemostatic Agent in Spinal Surgery: A Randomized Clinical Trial.
When common hemostatic methods, such as suturing, cautery, and compression, fail to arrest bleeding during surgery, various local hemostatic agents are used. We aimed to evaluate the hemostatic efficacy and safety of CollaStat (Dalim Tissen Co. Ltd., Seoul, Korea), a novel thrombin-containing, collagen-based topical haemostatic agent used in spinal surgery, by comparing it with Floseal (Baxter Healthcare, Deerfield, Illinois, USA). ⋯ The hemostatic efficacy and safety of CollaStat were found to be noninferior to those of Floseal. Therefore CollaStat can be safely and effectively used in spinal surgery.

The expanding use of three-dimensional (3D) printing in open vascular and endovascular neurosurgery presents a promising new tool in resident learning as well as operative planning. Recent studies have investigated the accuracy, efficacy, and practicality of 3D-printed models of patient-specific disease. ⋯ Models generated by 3D printing are anatomically accurate and aid in resident learning as well as operative planning in open vascular and endovascular neurosurgery. As advancements in printing methods are made and manufacturing costs decrease, this tool may supplement training on a wider scale in a field in which direct exposure to cases is limited.

Multicenter Study Observational Study
Outcomes and Surgical Considerations for Neurosurgical Patients Hospitalized With COVID-19 - A Multi-center Case Series.
Neurosurgical patients are at a higher risk of having a severe course of coronavirus disease 2019 (COVID-19). The objective of this study was to determine morbidity, hospital course, and mortality of neurosurgical patients during the coronavirus disease 2019 (COVID-19) pandemic in a multicenter health care system. ⋯ COVID-19 is rare among the inpatient neurosurgical population. In all cases, patients had multiple comorbidities. All symptomatic patients from the respiratory standpoint had complications during their hospitalization. Deaths of 3 patients who died within 30 days of hospitalization were all related to COVID-19 complications. Neurosurgical procedures were performed only if deemed emergent.

Enhanced recovery after surgery has been attempted in neurosurgery at a greater rate. However, concern exists regarding the feasibility of using enhanced recovery after neurosurgery (ERANS). How to manage available resources to safely perform ERANS and improve clinical outcomes has been the subject of much debate and discussion. ⋯ Applying an ERANS protocol was feasible, associated with a low incidence of complications, and acceptable intensive care unit and postoperative hospital lengths of stay. The findings from the present study might provide a new approach for the further research of ERANS.
