With the evolution of surgical approaches, endoscopic skull base surgery has emerged as a suitable alternative to many other invasive methods. The aim of this study was to investigate the efficacy and outcome of cranial endoscopy in treating various neurosurgical intracranial pathologies in terms of procedural success and complications. ⋯ Neuroendoscopic surgery has become safe and effective, as surgeon experience and learning have lowered the risk of complications, and offers a low-cost alternative intervention.

Traumatic dural sinus injuries following penetrating brain injury are rare but are often associated with significant morbidity and mortality. The management of significant defects is operative and can be challenging. In modern civilian practice, patients with these injuries typically receive extensive preoperative investigation and advanced perioperative monitoring. ⋯ Immediate repair of dural sinus injuries is feasible in the context of a low-resource wartime environment and should be attempted without delay. To our knowledge, this is the first case of successful use of a synthetic vascular graft for repair of a dural venous sinus injury in an ill-equipped hospital.

Cauda equina syndrome (CES) can have devastating neurological sequelae if surgical treatment is delayed. However, out-of-hours surgery (weekdays from 6:00 pm to 8:00 am and all weekend operations) can potentially result in higher rates of intraoperative complications, resulting in worse outcomes. In the present study, we have described our outcomes for patients with CES during an 8-year period (December 2011 to October 2019) with the aim of assessing the risk of out-of-hours surgery. ⋯ Our analysis has suggested that emergency decompressive surgery for patients with CES does not result in worsening of outcomes with out-of-hours surgery compared with in-hours. However, our findings also showed that no clear benefit exists to expediting surgery for those with severe presentations. Thus, decompressive surgery should be undertaken at the earliest possible time to safely do so.

Subependymal giant cell astrocytoma (SEGA) is a World Health Organization grade 1 neoplasm, which, due to its dubious morphologic features, may be misdiagnosed as a high-grade tumor at times. This tumor shows binary immunoexpression including both glial and neural markers, leading to a state of diagnostic quandary. Recent evidences have surmised the diagnostic utility of thyroid transcription factor 1 (TTF-1), spurring us to study the practicality of this marker in distinguishing SEGAs from its mimics. ⋯ The congruous finding of TTF-1 expression in SEGA and cells of the developing neuroepithelium in the medial ganglionic eminence hint toward a primogenitor cell with neoplastic potential in the presence of impelling factors.

Microsurgical treatment for a Cerebral Arteriovenous Malformation of the Central Sulcus.
Arteriovenous malformations (AVMs) are congenital neurovascular disorders frequently manifested in young adults. The clinical presentation is variable and depends on its location, size, and ability to steal flow from adjacent areas, but it depends mainly on the occurrence of bleeding.1 The treatment of these lesions when located in eloquent areas, especially around the central sulcus, is controversial. ⋯ We consider that surgical removal of many of these lesions is feasible when preoperative planning is performed,3 when it is based on deep anatomic knowledge, and particularly when using a refined microsurgical technique.1 In this 3-dimensional Video 1, we present a case of a cerebral AVM of the central sulcus in which we achieved complete resection with microsurgical treatment without any neurologic sequelae for the patient. The patient consented to publication of images.
