La prevalencia de los quistes aracnoideos en niños es del 1-3%. Son más frecuentes en el sexo masculino. Pueden localizarse tanto en el espacio intracraneal como a nivel espinal. Los intracraneales se clasifican en supratentoriales, infratentoriales y supra-infratentoriales. Los supratentoriales se subclasifican en de fosa media, hemisféricos de la convexidad, interhemisféricos, de la región selar e intraventriculares. Los infratentoriales se subdividen a su vez en supracerebelosos, infracerebelosos, hemisféricos, clivales y de ángulo pontocerebeloso. Por último, los espinales se clasifican según su localización extra o intradural y su afectación de raíces nerviosas
The prevalence of arachnoid cysts in children is 1-3%. They are more frequent in boys. They can be located intracranially or in the spine. Intracranial cysts are classified as supratentorial, infratentorial, and supra-infratentorial (tentorial notch). Supratentorial are divided into middle cranial fossa, convexity, inter-hemisferic, sellar region, and intraventricular. Infratentorial are classified into supracerebellar, infracerebellar, hemispheric, clivus, and cerebellopontine angle. Finally spinal arachnoid cysts are classified taking into account whether they are extra- or intradural, and nerve root involvement

PURPOSE: Cranial nerve microvascular decompression is a habitual neurosurgical procedure. Authors describe a new application of the Dextroscope (Volume Interactions, Ltd.), a virtual reality environment, to plan and properly simulate this kind of procedures. METHODS: In three cases of hemifacial spasm refractory to drugs and botulinum toxin treatment, the authors used a virtual reality workstation (Dextroscope) to develop an interactive simulation of craniotomy, approach, and Gore-Tex implant optimal size and position in order to reach vascular decompression of facial nerve. RESULTS: Three-dimensional interactive environment allowed the authors to virtually carry out craniotomy, to visualize vascular and nerve relationship, and finally, to select and to simulate best Gore-Tex graft positioning in each case. During surgical procedures, facial nerve vascular compressions were exposed and Gore-Tex grafts were successfully placed as it was virtually planned. Patient outcomes were excellent, with an average improvement of two units (0-4 grades of severity scale). CONCLUSION: Virtual reality environment can help the neurosurgeon to plan and train vascular decompression procedures. Use of appropriate craniotomy, knowledge of vascular and nerve relationship, and selection of optimum paddy size and position are the main useful applications of the Dextroscope in these procedures.
