Malformación de Chiari tipo i descubierta a través de una neuralgia glosofaríngea / Chiari type i malformation discovered through a glossopharyngeal neuralgia

La neuralgia glosofaríngea es una enfermedad rara cuyo tratamiento inicial es farmacológico. Cuando la terapia médica no es eficaz, se encuentran disponibles diferentes opciones quirúrgicas, incluida la radiocirugía estereotáctica, la descompresión microvascular o la sección de nervios. Se presenta el caso de una mujer de 26 años con neuralgia glosofaríngea y malformación de Chiari. Este tipo raro de neuralgia a veces se asocia con una anomalía de la unión cráneo-cervical. Se realizó una expansión de fosa posterior con duraplastia y descompresión microvascular. La paciente mostró una completa desaparición del dolor, sin necesidad de llevar a cabo la resección de las amígdalas cerebelosas (AU)

Neumoencéfalo a tensión, una extraña complicación del uso de oxígeno en neonatos. Descripción de un caso y revisión de la literatura / Tension pneumocephalus, an uncommon complication of oxygen therapy in preterm newborns. Presentation of a case and literature review

El neumoencéfalo a tensión es una complicación extremadamente rara en el uso de la ventilación a presión positiva en el neonato, cuyo diagnóstico requiere un alto grado de sospecha clínica. Presentamos el caso de un recién nacido prematuro, que recibió oxígeno a través de cánulas nasales de alto flujo debido a enfermedad de membrana hialina, propia de su prematuridad, y que desarrolló signos clínicos de hipertensión intracraneal. La ecografía transfontanelar y la TAC craneal pusieron de manifiesto un importante neumoencéfalo a tensión que fue evacuado a través de punción directa a través de la fontanela anterior (AU)

Tension pneumocephalus is an extremely rare complication of positive-pressure ventilation in neonates, the diagnosis of which requires a high degree of clinical suspicion. We present the case of a preterm newborn, who received high-flow nasal cannula oxygen therapy because of hyaline membrane disease, due to his prematurity, and developed clinical signs of intracranial hypertension. Transfontanellar ultrasound and cranial CT scan revealed significant tension pneumocephalus, which was evacuated with direct needle puncture through the anterior fontanelle (AU)

Spontaneous cerebrospinal fluid leaks in the anterior skull base secondary to idiopathic intracranial hypertension.

Spontaneous cerebrospinal fluid (CSF) leaks represent a clinical entity in which CSF rhinorrhea occurs in the absence of any inciting event. Spontaneous CSF leaks are associated with elevated intracranial pressure (ICP) or have underlying idiopathic intracranial hypertension (IIH). We report a cohort of patients who have undergone nasal endoscopic repair for spontaneous CSF leaks. We review our perioperative complications and the effectiveness of the nasal endoscopic approach to repair spontaneous CSF leaks. Also, we examine the evidence correlating spontaneous CSF leaks and IIH and the role of decreasing ICP in the treatment of nasal spontaneous CSF leaks. A retrospective analysis of patients with nasal spontaneous cerebrospinal fluid leaks was performed. Data on the nature of presentation, patient body mass index, defect location and size, ICP, clinical follow-up, and complications were collected. Thirty-five patients had nasal spontaneous cerebrospinal fluid leaks with evidence of IIH's symptoms. The most common sites were the cribriform plate, the ethmoid roof, and sphenoid lateral pterygoid recess. All patients underwent endonasal endoscopic surgery to repair the defect. Postoperatively, all patients underwent lumbar drainage and acetazolamide therapy. Nasal spontaneous cerebrospinal fluid leaks represent a surgical challenge because of their high recurrence rates. The most important factor for obtaining a successful repair in these patients is reducing their intracranial pressure through nutritional, medical, or surgical means.

Infarto cerebral tras apoplejía pituitaria: descripción de un caso y revisión de la literatura / Cerebral infarction after pituitary apoplexy: Description of a case and review of the literature

La apoplejía pituitaria es normalmente el resultado de un infarto hemorrágico que acontece a un adenoma hipofisario. La presentación clínica comprende un espectro muy amplio e incluye desde casos asintomáticos, el cuadro clínico clásico e incluso muerte súbita. La isquemia cerebral tras una apoplejía pituitaria ocurre muy raras veces. Se postulan como mecanismos etiopatogénicos el vasoespasmo y/o la compresión vascular arterial provocada por el propio tumor. En el presente artículo describimos un caso de apoplejía pituitaria asociada a infarto cerebral y discutimos la relación entre ambos eventos

Pituitary apoplexy is usually the result of haemorrhagic infarction in a pituitary adenoma. The clinical presentation varies widely and includes asymptomatic cases, classical pituitary apoplexy and even sudden death. Cerebral ischemia due to pituitary apoplexy is very rare. It may be caused by vasospasm or direct compression of cerebral vessels by the tumor. We report a case of pituitary apoplexy associated with cerebral infarction and discuss the relationship between the two events

Hematoma subdural crónico bilateral: análisis de una serie de 190 pacientes / Bilateral chronic subdural haematoma: Analysis of a series of 190 patients

Objetivos: Analizar las características clínicas, los factores de recidiva y el resultado quirúrgico de un grupo de pacientes con hematoma subdural crónico bilateral (HSCB) y compararlos con una serie de hematomas subdurales crónicos unilaterales (HSCU). Pacientes y métodos: Estudio retrospectivo que incluye a 1.523 pacientes, tratados quirúrgicamente durante un período de 30 años, de un hematoma subdural crónico. Los pacientes se dividieron en 2 grupos: el de estudio formado por 190 pacientes que presentaban un HSCB y el control formado por 1.333 pacientes que presentaban un HSCB. Resultados: La serie de estudio está formada por 126 varones (66,3%) y 64 mujeres (33,7%) con una edad media de 74,8±10,2 años. En el grupo control hay 870 varones (65,2%) y 463 mujeres (34,8%) con una edad media de 73,2% ± 12,1. El síntoma de inicio más frecuente fue el deterioro cognitivo en 63 pacientes (33,2%) en los bilaterales y en 416 (29,5%) en los unilaterales. Se produjeron 18 casos de recidiva (9,4%) en los bilaterales y 77 (5,7%) en los unilaterales (p = 0,027). La mortalidad fue de 10 casos (5,2%) en los bilaterales y de 55 (4%) en el grupo control. Se encontraron como factores significativos de recidiva: sexo masculino (p = 0,022), la ingesta de fármacos anticoagulantes/antiagregantes (p = 0,032) y la mala situación clínica al ingreso (p = 0,039). Conclusiones: El HSCB afecta de manera importante a los varones y la forma de presentación más habitual es la cefalea. Los factores más importantes que influyen en las recidivas son el sexo masculino, la ingesta de fármacos anticoagulantes/antiagregantes y la peor situación clínica al ingreso. Los índices de recidiva fueron significativamente superiores a los unilaterales

Objective: The aim of this study is to analyse the clinical findings and surgical results in a series of patients with bilateral chronic subdural haematoma (BCSDH), and compare the results with a series of patients treated for unilateral chronic subdural haematoma (UCSDH). Patients and methods: A retrospective study was performed on 1523 patients diagnosed and surgically treated for chronic subdural haematoma over a period of 30 years. Patients were divided into 2 groups: The study group consisting of 190 patients operated on for a BCSDH and the control group consisting of patients operated on for an UCSDH (1333 cases). Results: The patient series included 126 males (66.3%) and 64 females (33.7%), with a mean age at diagnosis of 74.8 ± 10.2. The control group consisted of 870 males (65.2%) and 463 women (34.8%), with a mean age of 73.2 ± 12.1. The most common presenting symptoms was cognitive impairment in 63 patients (33.2%) with BCSDH and 416 (29.5%) with UCSDH. Recurrence rates were 9.4% (18 patients) and 5.7% (77 patients) in unilateral and bilateral haematomas, respectively. The mortality was 10 patients (5.2%) with BCSDH and 55(4%) with UCSDH. Factors significantly related to recurrence in the univariate analysis were being male (P = .040), anticoagulant/antiplatelet therapy (P = .032), and poor neurological status at admission (P = .039). Conclusions: This study indicates that BCSDH is more frequent in males, and the most common presentation is headache. The most important factors influencing recurrences are being male, intake of anticoagulant-antiaggregant drugs, and worse clinical status at admission

Desarrollo «de novo» de un quiste aracnoideo supraselar / «De novo» development of a suprasellar arachnoid cyst

Los quistes aracnoideos (QA) intracraneales son lesiones quísticas formados a partir de las aracnoides y que tienen una prevalencia entre el 1-2% en la población pediátrica. Presentamos el caso clínico de un niño de 2 años que presentó inestabilidad para la marcha y episodios de desviación ocular; al nacimiento se le había realizado una ecografía transfontanelar que fue normal. Se le practicó una tomografía computarizada (TC) y resonancia magnética (RM) que evidenciaron un quiste aracnoideo supraselar acompañado de importante hidrocefalia. Se realizó una fenestración endoscópica del quiste con remisión completa de la sintomatología. En la revisión de la literatura únicamente hemos encontrado 6 casos previos de QA sin un origen congénito o traumático, y exclusivamente uno de ellos de localización supraselar. Analizamos las características clínicas, radiológicas y el tratamiento en los casos publicados con anterioridad

Intracranial arachnoid cysts are fluid-filled cavities that arise within the cranial arachnoid, representing approximately 1%-2% of all intracranial lesions among the paediatric population. We present the case of a 2-year-old boy who presented with instability and episodes of ocular deviation. A computed tomography scan (CT scan) and magnetic resonance imaging (MRI) of the brain revealed a suprasellar cyst and obstructive hydrocephalus. At birth a transfontanellar ultrasound was normal. The cyst underwent endoscopic fenestration with complete remission of symptoms. In the review of the literature, we found only 6 previous cases of an intracranial arachnoid cyst whose origin was not clearly congenital or traumatic, and ours is the second case of a suprasellar arachnoid cyst to arise de novo. The clinical features, imaging characteristics and treatment of the previously reported cases are discussed

La fenestración endoscópica como tratamiento de los quistes aracnoideos intracraneales / Endoscopic fenestration to treat intracranial arachnoid cysts

Los quistes aracnoideos son lesiones quísticas con un contenido similar al líquido cefalorraquídeo. Representan alrededor del 1% de todas las lesiones expansivas intracraneales y son característicos de las dos primeras décadas de la vida, aunque en ocasiones se diagnostican en adultos. Presentamos una revisión sobre nuestra experiencia en el tratamiento quirúrgico de quistes aracnoideos intracraneales. Material y métodos: Realizamos una revisión de 103 niños menores de 16 años intervenidos quirúrgicamente por un quiste aracnoideo intracraneal en los que se empleó una derivación cistoperitoneal en 53 casos; una craneotomía con fenestración del quiste, en 44 niños, y 11 casos con fenestración por vía endoscópica. Resultados: En todos los pacientes se consiguió alivio de la sintomatología y reducción o desaparición del quiste. Se presentaron 21 complicaciones quirúrgicas: 12 en los pacientes tratados con válvula (22.6%) y 9 en los sometidos a craneotomía (20.4%). La mortalidad de la serie fue de dos casos (1.95%). Discusión y conclusiones: El tratamiento de los quistes aracnoideos intracraneales debe reservarse exclusivamente para los casos sintomáticos. La craneotomía con fenestración de las membranas y la derivación cistoperitoneal son buenas opciones de tratamiento, ya que consiguen un buen control, tanto del tamaño del quiste como en la resolución de la sintomatología. La mejor opción terapéutica es en la actualidad la fenestración endoscópica, ya que se trata de una técnica poco invasiva, que no requiere la implantación de materiales extraños y cuyo índice de complicaciones y recidivas es relativamente bajo...

[Reversible porencephalic cyst related to shunt dysfunction]. / Cavidad porencefálica reversible secundaria a disfunción valvular.

INTRODUCTION: The surgical treatment of hydrocephalus is one of the most commonly procedures of modern pediatric neurosurgical practice, and cerebrospinal fluid shunts are the main means of treatment of hydrocephalus, being independent of site of obstruction and ventricular shunt complications are frequent, especially in children. The most common complications are shunt obstructions, mechanical disconnections, overdrainage and infection. CASE REPORT: A 7.5-year-old girl with ventriculoperitoneal shunt presented with intermittent headache. A head computed tomography scan revealed a cyst located in right temporal lobe. After ventriculoperitoneal shunt revision, a gradual resolution of the cyst was demonstrated on computed tomography. CONCLUSIONS: Cerebrospinal fluid porencephaly is a rare postoperative complication of a ventricular shunt that results from dysfunction of the distal catheter, especially in children with taut ventricles.

TITLE: Cavidad porencefalica reversible secundaria a disfuncion valvular.Introduccion. El tratamiento quirurgico de la hidrocefalia es uno de los procedimientos quirurgicos mas habituales en la neurocirugia pediatrica, y las derivaciones ventriculoperitoneales constituyen una herramienta fundamental en el tratamiento de la hidrocefalia tanto infantil como del adulto. Las complicaciones de las valvulas son relativamente frecuentes, sobre todo en la poblacion pediatrica, y, entre estas, las mas habituales incluyen: las obstrucciones, las desconexiones, el hiperdrenaje y las infecciones. Caso clinico. Niña de 7,5 años, portadora de una valvula ventriculoperitoneal, que presentaba cefalea intermitente. Un estudio con tomografia computarizada demostro una lesion quistica temporal derecha. Tras la revision valvular, la tomografia computarizada evidencio la reduccion del quiste. Conclusiones. La formacion de una cavidad porencefalica es una complicacion poco frecuente. Se relaciona con problemas en el cateter distal en pacientes con ventriculos dilatados y de las que existen escasas referencias en la bibliografia.
