Review Meta Analysis
Effectiveness of Sealants in Prevention of CSF Leakage after Spine Surgery: a Systematic Review.
Sealants are often used in spine surgery to prevent postoperative cerebrospinal fluid (CSF) leakage. ⋯ Currently available sealants seem not to reduce the rate of CSF leakage in spine surgery. In endoscopic and minimally invasive surgery, the CSF leakage rate is less frequent compared with open, conventional surgery regardless of sealant use.

Review Case Reports
Hemangioblastoma of the Cerebral Aqueduct Removed via a Sitting, Supracerebellar Intracollicular Approach.
Tumors protruding into the cerebral aqueduct are rare, and tumors arising from within the cerebral aqueduct are rarer still. ⋯ We report the first case of an aqueductal hemangioblastoma and describe our use of a sitting, supracerebellar, intracollicular approach to access tumors occupying this cerebrospinal fluid space.

Comparative Study
Comparison of Satellite Sign and Island Sign in Predicting Hematoma Growth and Poor Outcome in Patients with Primary Intracerebral Hemorrhage.
Satellite sign (SS) and island sign (IS) are novel noncontrast computed tomography (CT) predictors of hematoma growth. The aim of this study was to compare diagnostic performance of IS and SS in predicting hematoma growth and functional outcome in patients with intracerebral hemorrhage (ICH). ⋯ IS seems to be an optimal shape irregularity imaging marker for predicting hematoma growth and functional outcome in patients with ICH.

Checkpoint immunotherapy (CIT) is an emerging and exciting treatment modality for the treatment of cancer. Much excitement has ensued in the potential of CIT to revolutionize the treatment and prognosis of brain metastases. ⋯ However, several questions have arisen, in particular, the timing at which SRS and CIT should be administered relative to each other. We reviewed the reported data and attempted to offer a potential answer to this question.

Evidence continues to emerge regarding the inverse relationship between high neurointerventional case volume and complication rates, leading several medical/surgical societies to recommend minimum volumes for specific procedures. Recent data suggest few centers are meeting these requirements. We report a single center's neurointerventional complication rates with associated case volumes, along with a review of the literature. ⋯ We provided a single-center experience of the relationship between neurointerventional procedural case volume and complication rates in the growth phase of our center's establishment. We demonstrated that as our center was being developed, specific procedural staffing measures allowed proficiency maintenance, acquisition of new techniques, and complication avoidance, whereas specific case volumes crossed the suggested thresholds as defined in the literature.
