Review Meta Analysis
Minimally Invasive Surgical Outcomes for Deep-Seated Brain Lesions Treated with Different Tubular Retraction Systems: A Systematic Review and Meta-analysis.
Minimally invasive surgery using tubular retractors was developed to minimize injury of surrounding brain during the removal of deep-seated lesions. No evidence supports the superiority of any available tubular retraction system in the treatment of these lesions. We conducted a systematic review and meta-analysis to evaluate outcomes and complications after the resection of deep-seated lesions with tubular retractors and among available systems. ⋯ Tubular retractors represent a promising tool to achieve maximum safe resection of deep-seated brain lesions. However, there does not seem to be a statistically significant difference in extent of resection or complication rates among tubular retraction systems.

Review Case Reports
Re-rupture following flow diversion of a dissecting aneurysm of the vertebral artery: case report and review of the literature.
Dissecting aneurysms of the posterior cerebral circulation can wield significant treatment challenges with devastating clinical outcomes. Despite an expanded therapeutic armamentarium, these vascular lesions remain relatively difficult to diagnose and portend high associated morbidity and mortality. ⋯ The literature posits that nonsaccular, fusiform, and dissecting aneurysms of the vertebrobasilar circulation can be occluded with consistency and success using flow diversion techniques. Endovascular treatment of a ruptured dissecting aneurysm of the VA is technically feasible and can be performed with or without parent artery occlusion. Outcomes following flow diversion of the posterior circulation may depend on the location of the dissection and viability of collateral circulation. In the present case, adequate coverage of the aneurysm did not portend a positive outcome.

Review Case Reports
Diffuse Traumatic Sub Arachnoid Hemorrhage Mimicking Aneurysmal Bleeding Secondary to Ophthalmic Artery Avulsion: A Case Report and Literature Review.
Traumatic subarachnoid hemorrhage (SAH) is a common finding following traumatic brain injury. In some cases, it can be associated with hydrocephalus. This type of hemorrhage is mostly caused by the rupture of small vessels in the brain and is usually managed conservatively. ⋯ Traumatic avulsion of the ophthalmic artery may result in diffuse SAH, mimicking that of aneurysmal rupture. This case shows that management of early complications, such as hydrocephalus and seizures, should be the main aim. Surgical or endovascular treatment of the injured artery, however, would be unnecessary.

Review Case Reports
Spinal metastasis of cerebral Glioblastoma (GBM) with genetic profile: case report and review of literature.
Spinal metastasis of cerebral glioblastoma (GBM) is rare, with some reports suggesting a prevalence of 1%-2%. ⋯ We are reporting these 2 cases due to the rarity of spinal metastasis in GBM. We reviewed the current literature and included genetic and molecular profiles in the discussion. Currently, there are no established treatment guidelines for GBM spinal metastasis. The Stupp protocol after initial brain surgery for GBM did not appear to have beneficial effects on prolonging survival in these patients with spinal metastasis. The goal of treatment was primarily to alleviate pain and neurologic deficits with no effect on overall outcome. Prognosis following the diagnosis of spinal metastasis is poor.
