Since 2010, the Congress of Neurological Surgeons (CNS) has offered a neurosurgical skills simulation course for residents and medical students. The authors describe their experience with incorporation of two neurosurgical skills simulation modules into the dedicated resident training curriculum of a single ACGME-accredited training program, using lumbar dural repair (5) and posterior cervical laminoforaminotomy modules from the CNS simulation initiative (6). ⋯ Duty hour limitations and regulatory pressure for enhanced quality and outcomes may limit access of neurosurgical residents to fundamental skills training. Fundamental skills training as part of a validated simulation curriculum can mitigate this challenge to residency education. National development of effective technical simulation modules for use in individual residency training programs is a promising strategy to achieve these goals.

To describe 1 center's experience using carotid artery stenting (CAS) or carotid endarterectomy (CEA) as a treatment strategy in patients with bilateral carotid artery stenosis. ⋯ Good outcomes can be achieved in patients with bilateral carotid artery stenosis when treatment selection is based on each individual patient's clinical characteristics and with a proper combination of staged CEA and CAS.

We describe the resection of cerebellar cystic tumors using pure neuroendoscopy. This technique consists of performing all of the procedures under an endoscopic view, with the instruments introduced into the operative field coaxially to the endoscope through a trocar. ⋯ The pure neuroendoscopic technique was shown to be minimally invasive and a successful and secure method to treat cystic cerebellar tumors.

Seizures are relatively common in patients harboring cerebral arteriovenous malformations (AVMs). Because the pathogenesis of AVM-associated epilepsy is not well-defined, we aim to determine the factors associated with seizure presentation in AVM patients. ⋯ Large, unruptured, cortical nidi are most prone to seizure presentation in patients referred for radiosurgery. Further investigations of the molecular biology, neuronal and glial physiology, and natural history of AVM-associated epilepsy appear warranted.

We studied a poorly known form of cerebrospinal fluid hypotension characterized by cervical myelopathy, a considerable growth in volume of the venous plexus of the cervical spine, and absence of headache. This form was first described by Miyazaki. We reported a case brought to our attention, reviewed the literature, and formulated etiopathogenic theories that might explain all the various clinical aspects of this pathology.
