Review Meta Analysis Comparative Study
Treatment of middle cranial fossa arachnoid cysts: a Systematic Review and Meta-analysis.
To review the literature and analyze the efficacy and safety of 3 surgical methods (neuroendoscopic fenestration, microsurgical fenestration, and cystoperitoneal shunting) for middle cranial fossa arachnoid cysts (MCFACs). ⋯ All 3 surgical methods are effective for MCFACs, but considering safety, neuroendoscopic fenestration may be the best initial procedure.

Review Case Reports
Histologic Evidence for Arteriovenous Malformation-Like Vasculature Occurring within an Intracerebral Schwannoma: A Case Report and Review of the Literature.
The phenomenon of intracerebral schwannoma is exceedingly rare, and its etiology still a matter of debate. No documented cases of intracerebral schwannoma containing vascular elements consistent with those of an arteriovenous malformation (AVM) have been reported. We describe such a case here. ⋯ To our knowledge, this is the first case of an intracerebral schwannoma with AVM-like characteristics to be reported in the literature. We hypothesize that the co-occurrence of this rare pathologic entity is caused by an interrelated etiologic process, with the tumor microenvironment of the schwannoma inciting the development of the vascular malformation.

Radical resection of dominant insular gliomas is difficult because of their close vicinity with internal capsule, basal ganglia, and speech centers. Brain mapping techniques can be used to maximize the extent of tumor removal and to minimize postoperative morbidities by precise localization of eloquent cortical and subcortical areas. ⋯ Brain mapping during awake craniotomy helps to maximize extent of tumor resection while preserving neurologic function in patients with dominant insular lobe glioma.

Review Case Reports
Postoperative cerebral vasospasm following transsphenoidal pituitary adenoma surgery.
Cerebral vasospasm following a transsphenoidal resection of a pituitary adenoma is a devastating occurrence that can lead to delayed cerebral ischemia and poor neurologic outcome if not diagnosed and treated in a timely manner. The etiology of this condition is not well understood but can lead to significant arterial vasospasm that causes severe ischemic insults. In this paper, we identify common presenting symptoms and essential management strategies to treat this harmful disease. ⋯ Cerebral vasospasm following transsphenoidal surgery is a dangerous disease that can lead to a high likelihood of mortality if not identified and treated. Early postoperative events, such as peritumoral subarachnoid hemorrhage and hemiparesis, may be factors associated with post-transsphenoidal surgery vasospasm. Effective treatment options used in patients that regained complete neurologic recovery were by inducing hypertension, maintaining euvolemia, and administering nimodipine.

An overview of the development of neuroendoscopy at the neurosurgery department, Ibn Sina Hospital in Kuwait, is presented with an outline of difficulties and obstacles faced by the field until it reached its current status. The factors and solutions that helped us overcome these problems are also elaborated on. After a modest beginning few years ago, endoscopic skull base procedures, intraventricular neuroendoscopy, and spinal endoscopy are regularly performed in the department. ⋯ Importantly, a multitude of essential facilities should be available to make such a pattern of practice possible. In our experience, this was made possible through continued efforts that have finally paid off and gradually led to a complete shift of the face of neuroendoscopic practice in our department. Our future endeavors aim at further development of neuroendoscopy in the department to create a center of excellence.
