Review Meta Analysis
Symptomatic and Radiographic Improvement Following Surgery for Posterior Fossa Arachnoid Cysts: Meta-Analysis and Literature Review.
Arachnoid cysts are benign, intradural collections of cerebrospinal fluid that are often asymptomatic but, in rare instances, will grow and may cause symptoms. When these are in the posterior fossa, the symptomatology greatly ranges, and the indications for surgery are not well defined. The objective of this study is to examine radiographic and symptomatic outcomes following surgery for posterior fossa arachnoid cysts (PFAC). ⋯ Although there is a high rate of radiographic improvement for PFAC surgery, there is a wide variety of presenting symptoms with differing postoperative improvement rates. This study reinforces the importance of preoperative counseling regarding symptomatic outcomes for PFAC surgery, with supporting statistical analysis but limited by the sample sizes available.

Spinal injuries occur in 3% of all patients with trauma, most commonly in males, and often as a result of high-velocity impact followed by abrupt deceleration. The most affected region after spinal trauma is the thoracolumbar junction because of the anterior center of gravity at the T12-L1 vertebral level and the relatively stiff thoracic spine uniting with the mobile lumbar spine. Many classifications exist to guide the choice of operative versus nonoperative management of traumatic injuries at this site. ⋯ Ignoring this aspect of thoracolumbar management often contributes to the development of posttraumatic malalignment and other complications. This review recommends that a new or modified classification system accounts for sagittal segmental alignment factors, including the level of the injured vertebra, the number of affected adjacent levels, imaging techniques with better specificity and sensitivity, and assessment for osteoporosis. Case studies are included to show the importance of segmental sagittal alignment and the vertebral level on patient outcomes.

The International Stereotactic Radiosurgery Society aims to establish evidence-based guidelines for single-fraction stereotactic radiosurgery (SRS) in treating intracranial cavernous malformations. ⋯ This meta-analysis suggests SRS is an effective intervention for intracranial cavernous malformations, significantly reducing hemorrhage rates and improving seizure outcomes. International Stereotactic Radiosurgery Society practice guidelines are provided.

Review Case Reports
Cervical Intradural Fungal Infection Masquerading as a Meningioma in an Immunocompetent Patient: A Case report and Systematic Review.
Intradural spinal fungal infection is a rare phenomenon that can carry a significant increase in morbidity and mortality. This systematic review and case report provides a presentation of a 75-year-old male patient with an intradural cervical mass that was diagnosed as a fungal infection intraoperatively. We analyze and report on intradural spinal fungal infections in immunocompetent patients. ⋯ Intradural fungal infections are rare, with only 10 total cases reported in the past 25 years. Nonetheless, they can be associated with significant mortality and morbidity. Thus, the timeline from presentation to intervention should be evaluated and determined carefully.

Review Historical Article
Historical roots of modern neurosurgical cadaveric research practices: dissection, preservation, and vascular injection techniques.
Because of the complexity of the brain and its structures, anatomical knowledge is fundamental in neurosurgery. Anatomical dissection, body preservation, and vascular injection remain essential for training, teaching, and refining surgical techniques. This article explores the historical development of these practices and provides the contextual background of modern neurosurgical cadaveric brain models. ⋯ In 1868, August Hofmann synthesized formaldehyde, markedly improving tissue preservation. Later, William Kruse introduced latex in 1939, and Sidney Sobin introduced silicone in 1965 for vascular studies. These advancements laid the foundation for modern neurosurgical cadaveric studies, many remaining relevant today.
