Case ReportsMultiple cerebral aneurysms in a neonate: occlusion and rupture.
Aneurysmal subarachnoid hemorrhage in a neonate is exceedingly uncommon. The authors report the case of a neonate with a large anterior communicating artery aneurysm, accessory left middle cerebral artery aneurysm, and left internal carotid artery (ICA) fusiform aneurysm. ⋯ The large aneurysm was treated with detachable coils and the patient made a significant recovery. Of the 15 case reports of cerebral aneurysms in neonates that have been published, none has contained a description of multiple aneurysms or a discussion of endovascular treatment.

How low can you go? Intracranial pressure, cerebral perfusion pressure, and respiratory obstruction in children with complex craniosynostosis.
Elevated intracranial pressure (ICP) is a well-recognized complication affecting children suffering from complex forms of craniosynostosis. The effects of ICP, including those on vision, and the underlying mechanisms involved remain uncertain. The aim of this study was to examine the relationships among ICP, cerebral perfusion pressure (CPP), and the episodic alterations in respiratory obstruction that are common in children with craniosynostosis. ⋯ The findings of this study indicate that ICP, CPP, and respiratory obstruction interact in a vicious cycle, an observation that helps explain the pattern of plateau waves of elevated ICP characteristic among children with complex forms of craniosynostosis. The data gathered in this series revealed levels of CPP considerably lower than those described previously in clinical reports. Such reductions in CPP most likely contribute to the neurological, cognitive, and ophthalmological morbidity from which these children suffer frequently; therefore, the results of this study have important implications for the management of children with complex forms of craniosynostosis as well as for our understanding of the control of cerebral blood flow in general.

Case ReportsVisual changes after gamma knife surgery for optic nerve tumors. Report of three cases.
Tumors involving the optic nerve (optic glioma, optic nerve sheath meningioma) are benign but difficult to treat. Gamma knife surgery (GKS) may be a useful treatment. The authors present data obtained in three such cases and record the effects of GKS.

Treatment of essential trigeminal neuralgia with gamma knife surgery.
The authors present the long-term follow-up results (minimum 5 years) of patients with essential trigeminal neuralgia (TN) who were treated with gamma knife surgery (GKS). ⋯ The initial success rate of pain relief was high and comparable to that reported in other studies. A higher than usual incidence of sensory impairment after GKS could be the long duration of follow-up study and due to the detailed neurological examination.

Case ReportsGlossopharyngeal neuralgia treated with gamma knife surgery: treatment outcome and failure analysis. Case report.
Glossopharyngeal neuralgia (GPN) is a rare condition in which patients present with intractable deep throat pain. Similar to trigeminal neuralgia (TN), treatment with microvascular decompression (MVD) has been successful in both. Because gamma knife surgery (GKS) has also been shown to be effective in treating TN, it seemed reasonable to apply it to GPN. The authors present the first report of GKS-treated GPN in a patient who presented with severe, poorly controlled GPN and who refused MVD.
