Poorly understood cranial fluid accumulations are frequently observed after decompressive craniectomy and often termed "external hydrocephalus." These findings are difficult to explain using traditional models of hydrocephalus. ⋯ Closure of the cranial defect with cranioplasty improves cerebral blood flow and CSF pulsatile circulation and is frequently sufficient to resolve the external hydrocephalus.

Review Case Reports
Orbito-Temporal Bone Cyst of Metastatic Breast Cancer: Case Report and Literature Review.
Metastatic breast cancer in the bone rarely has a cystic appearance, and while it is common in the orbit, its metastasis to the orbitotemporal skull is rare. Consequently, it is difficult to diagnose it. We report and discuss a rare case of metastatic breast cancer with simple cyst appearance in the orbitotemporal region of the skull. ⋯ Metastatic breast cancer should be considered in the differential diagnosis even if it appears as a simple cyst in the orbitotemporal bone after long-term remission.

Meta Analysis
Association of endothelin receptor type A with intracranial aneurysm in 20,609 East Asians: An updated meta-analysis.
Genome-wide association studies have reported an association between the EDNRA gene and intracranial aneurysm (IA) in European and Japanese populations; however, there is no study on this polymorphism in other Asian populations. Therefore, we performed an extensive large-scale meta-analysis for association of the rs6841581 variant of EDNRA with IA susceptibility in East Asian population. ⋯ The genetic variant of EDNRA, rs6841581, was significantly associated with increased risk of IA. Our findings indicate that it could be used as an IA-predicting variant in East Asian populations.

Meta Analysis
Stereotactic radiosurgery for brainstem cavernous malformations: An updated systematic review and meta-analysis.
This study was conducted to achieve more conclusive evidence for the efficacy of stereotactic radiosurgery (SRS) for brainstem cavernous malformations (BSCMs). ⋯ SRS using a relatively low marginal dose can be a safe and effective treatment for BSCM. Further prospective studies are necessary to confirm the optimal radiation dose and efficacy of SRS for BSCMs.

Randomized Controlled Trial Comparative Study
Reoperation Following Primary Lumbar Discectomy With or Without Implantation of a Bone-Anchored Annular Closure Device: Surgical Strategies and Clinical Outcomes.
To determine whether presence of a bone-anchored annular closure device (ACD) impacts reoperation strategies and subsequent outcomes. ⋯ In patients undergoing post-discectomy reoperation, patients with an ACD were treated with similar operative techniques, were not exposed to additional surgical risks, and reported comparable clinical outcomes versus those without an ACD.
