Introducción: El ganglioglioma es un tumor primario, de bajo grado, del sistema nervioso central constituido por una población celular mixta de elementos gliales y neuronales. Representan entre el 0,4 al 2% de todos los tumores intracraneales y afectan fundamentalmente a niños y adultos jóvenes. Métodos: Entre los años 1995 y 2008 hemos tratado en nuestro hospital 20 pacientes (12 adultos y 8 niños) con ganglioglioma intracraneal. Revisamos retrospectivamente el sexo, el síntoma de inicio y la edad, sintomatología y tiempo de evolución, exploración neurológica, localización del tumor, aspecto en la tomografía computarizada y resonancia magnética, el tratamiento quirúrgico y la evolución. Todos los pacientes fueron intervenidos quirúrgicamente y la extensión de la resección fue evaluada de la hoja operatoria y del seguimiento neurorradiológico. Resultados: La media de edad de los pacientes fue de 26,4 años (rango 1-75) y el ratio mujer/varón fue de 1.5:1. Excepto en un caso, todos los pacientes debutaron con crisis epilépticas, con una duración media antes del diagnóstico de 7,4 años (rango 1-29). Diecisiete tumores estaban localizados en el lóbulo temporal (9 derechos y 8 izquierdos). Se realizó extirpación macroscópicamente completa en 17 pacientes y subtotal en los 3 restantes. Se presentaron 4 recidivas que fueron tratadas mediante reintervención, añadiéndose radioterapia en uno de los casos. El tiempo medio de seguimiento fue de 8,5 años (rango 22 meses-14 años), la supervivencia libre de enfermedad a los 5 años fue del 85% y la supervivencia global del 95%. Conclusiones: Las crisis epilépticas, que constituyen el síntoma más frecuente mejoran de forma significativa tras la extirpación quirúrgica. El tratamiento quirúrgico es la primera opción terapéutica en este tipo de tumores, y ante la presencia de resecciones subtotales o recidivas tumorales la mejor indicación de tratamiento es la reintervención. La radioterapia debe reservarse únicamente para las formas malignas (AU)
Introduction: A ganglioglioma is a type of primary central nervous system low grade tumour composed of mixed populations of glial and neuroepithelial elements. They accounts for 0.4 to 2% of all intracranial tumours and appear more commonly in children and young adults. Seizures, which are the most important symptom in these tumours, improve significantly after surgical excision. Methods: Between 1995 and 2008, 20 patients with (12 adults and 8 children) with intracranial ganglioglioma were treated at our hospital. Clinical information obtained by chart review included sex, age at onset of symptoms, clinical history, results of neurological examination, tumour location, CT and MRI appearance, surgical results and follow-up. All patients underwent tumour resection and the extent of surgery was determined from the surgical reports and postoperative imaging studies. Results: The median age of patients was 26.4 years (range, 1-75 years), and the female to male ratio was 1.5:1. Except in one case, all patients had seizures with a median duration before diagnosis of 7.4 years (range 1-29). Seventeen tumours were located in the temporal lobe (9 right and 8 left). Macroscopically complete excision was performed in 17 patients and subtotal in the remaining 3. There were 4 cases of recurrence treated by surgery and radiotherapy being added in one case. The mean follow up was 8.5 years (range 22 months-14 years) and disease free survival at 5 years was 85% and an overall survival of 95%. Conclusions: The seizures, which are the most frequent symptoms, significantly improved after surgical removal. Surgery is the first choice of therapy in these tumours, and in the presence of subtotal resection or tumour recurrence the best indication for treatment is repeat surgery. Radiotherapy should be reserved only for malignant forms (AU)

Guns bullet or captive bolt is used as a weapon for stunning animals as a prelude to sacrifice. Placed in front of it induce an immediate loss of consciousness, thus achieving a "humanization" of process. It's use for suicide is rare, almost exclusively of people who have access to them because of their occupation, causing severe injuries to the brain. We analyse three cases presented in our service. One of them dies as a result of injuries.

OBJECTIVE: to analyze the clinical, radiological and surgical outcome of a series of filum terminale ependymomas. Patients and methods. This retrospective study involved 20 patients with 21 ependymomas of the filum terminale encountered during a 21 year period (1988- 2008). All patients were diagnosed using MRI and surgically treated. RESULTS: the male: female ratio was 1:1.5, and the mean age at diagnosis was 44.8 years (range 15-64). First symptom included radicular pain (12 cases) and lumbar pain in the other 8 cases, with average symptom duration of 8.7 years (range 0-6-32). All patients underwent open biopsy, seventeen tumours received gross-total resection and 4 received subtotal resection. Histologically, 20 tumours were myxopapillary ependymomas (grade I) and 1 case a grade II ependymoma. The mean follow-up period was 8 years (range 1-18 years). CONCLUSIONS: filum terminale ependimomas are slow growing tumours of the cauda equina with a high incidence in young adults. The most common presentation is with low back pain long time evolution. Although ependymomas of the filum terminale are thought to be benign, local recurrence is not uncommon.

Objetivos. Analizar las características clínicas,radiológicas y los resultados quirúrgicos de una serie de ependimomas del filum terminal. Pacientes y método. Se estudia retrospectivamente 20 pacientes con 21 ependimomas del filum terminal tratados durante un período de 21 años (1988-2008).Todos los pacientes fueron diagnosticados con resonancia magnética e intervenidos quirúrgicamente. Resultados. La relación varón-mujer fue de 1:1.5 yla media de edad al diagnóstico de 44.8 años (rango 15-64). El primer síntoma fue dolor radicular (12 casos) y lumbalgia en los 8 restantes, con una duración mediade la sintomatología antes del diagnostico de 8.7 años(rango 0.6-32). Todos los pacientes fueron intervenidos quirúrgicamente realizándose resección completa de 17 tumores y subtotal de 4. Histológicamente 20 tumoresfueron ependimomas mixopapilares (grado I ) y un caso grado II. El período de seguimiento fue de 8 años (rango1-18).Conclusiones. Los ependimomas del filum terminal, son tumores de crecimiento lento con una mayor incidencia en adultos jóvenes. La forma de presentación más habitual es con dolor lumbar con un largo tiempo de evolución. Aunque la mayoría son tumores de bajo grado histológico, tienen una especial tendencia a crecer y las recidivas locales no son raras (AU)

A head fixation device with pins is commonly used for immobilization of the patients during neurosurgical procedures. Despite its appropriate management, it may be the cause of some serious complications such as skull perforation and intracranial injuries.We report the case of a 19-years-old young admitted for a endoscopic third ventriculostomy who developed an epidural haematoma due to the penetration of the skull by a pin.
