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.

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.

Glioblastoma invoking 'killer' rabbits of the Middle Ages.
We present the unusual appearance on brain magnetic resonance imaging of a glioblastoma with an uncanny shape of a rabbit. By invoking fearsome "killer" rabbits depicted in the art and literature of the Middle Ages, this image is an eerie reminder of the current lethality of this disease. There is a pressing need for more effective treatments for glioblastoma.

Moyamoya disease is a cerebral vasculopathy characterized by stenosis of the terminal internal carotid artery, proximal middle cerebral artery, and anterior cerebral artery. There is an association between moyamoya vasculopathy and Graves disease, primarily in Asian populations. Here, we present the largest series of non-Asian, predominantly Latino patients with moyamoya vasculopathy in the setting of Graves thyrotoxicosis, as well as the largest review of the literature to date. ⋯ Moyamoya vasculopathy associated with Graves disease thyrotoxicosis in non-Asian women may be more common than previously thought. In addition, our series suggests that thyrotoxicosis promotes the progression of vasculopathy. Based on our review, there is no significant difference in clinical improvement between proper medical and surgical therapies. Aggressive medical therapy should be considered first-line treatment for moyamoya vasculopathy with Graves thyrotoxicosis, with neurosurgical rescue reserved for medically refractory cases.
