Cerebral arterial vasospasm complicating supratentorial meningioma resection: illustrative cases.

Background: Cerebral arterial vasospasm is a rare complication after supratentorial meningioma resection. The pathophysiology of this condition may be similar to vasospasm after aneurysmal subarachnoid hemorrhage, and treatment options may be similar.

Observations: The authors present two cases of cerebral vasospasm after supratentorial meningioma resection and perform a systematic literature review of similar cases.

An Incidental Finding of Ecchordosis Physaliphora in a Case of Abducens Nerve Palsy: Case Report.

Ecchordosis physaliphora (EP) is a rare non-malignant mass that originates from remains of the notochord and is typically asymptomatic. A 42-year-old man presented with sudden onset of painless horizontal diplopia and his neurological exam showed sixth cranial nerve palsy. Magnetic resonance imaging (MRI) identified a non-enhanced retroclival mass (EP) with increased signal intensity on T2 and decreased signal intensity on T1-weighted sequences.

Benign extracerebral fluid collection in infancy as a risk factor for the development of de novo intracranial arachnoid cysts.

Object: Intracranial arachnoid cysts are a relatively common benign intracranial pathology, accounting for as many as 0.75%-1% of nontraumatic CNS lesions. Although it has already been demonstrated that rupture of arachnoid cysts may lead to subdural hematomas/hygromas, no study to date has investigated benign extracerebral collection in infancy as a possible predisposing factor for further development of arachnoid cysts.

Clinical outcomes of temporary shunting for infants with cerebral pseudomeningocele.

Objective: Although in the case of subdural collections temporary shunting has been suggested as a viable alternative for definitive drainage of the accumulated fluid until restoration of the normal CSF dynamics, there is no agreement on the best management strategy for pseudomeningocele.

Methods: The authors performed a retrospective chart review in order to evaluate the clinical outcomes of infants temporarily shunted for pseudomeningocele without encephalocele at our institution (The University of Illinois at Peoria/Illinois Neurological Institute) in the period from 2004 to 2012. The epidemiological characteristics, clinical management, and final outcomes of such subpopulation were compared with a control group which received temporary shunting for subdural hematomas (SDH) during the same period.

Performance analysis of the protective effects of bicycle helmets during impact and crush tests in pediatric skull models.

Object: Bicycle accidents are a very important cause of clinically important traumatic brain injury (TBI) in children. One factor that has been shown to mitigate the severity of lesions associated with TBI in such scenarios is the proper use of a helmet. The object of this study was to test and evaluate the protection afforded by a children's bicycle helmet to human cadaver skulls with a child's anthropometry in both "impact" and "crushing" situations.

Definition and measurement of rider-intrinsic physical attributes influencing all-terrain vehicle safety.

Object: All-terrain vehicle (ATV) usage has grown tremendously over the years, reaching 9.5 million vehicles in use in 2007. Accompanying this growth has been a concomitant increase in rider morbidity (including traumatic brain and spine injuries) and death, especially in children.
