RESUMO

El lugar más común de fístulas de líquido cefalorraquídeo (LCR) es el suelo de la fosa craneal anterior, menos comúnmente el seno esfenoidal. Solo el 3-4% de fístulas de LCR son espontáneas. Nosotros presentamos el cuarto caso clínico de rinorraquia secundaria a meningocele transclival, lugar muy poco común de asiento de estas lesiones, y discutimos la vía de abordaje. Varón de 39años, sin antecedentes de traumatismo previo, historia reciente de salida de líquido transparente a través de las ventanas nasales y cuadro de meningitis. La tomografía computarizada y la resonancia magnética mostraron el defecto óseo clival y meningocele transclival. El defecto fue reparado mediante abordaje endonasal endoscópico transesfenoidal transclival con resultado favorable. A pesar de la rareza del meningocele transclival, se recomienda considerarlo en el diagnóstico diferencial de las fístulas nasales espontáneas. El abordaje endonasal endoscópico es una técnica directa que ofrece resultados satisfactorios en la resolución de rinorrea de LCR


The most common site of CSF leakage is the floor of the anterior cranial fossa, and less commonly in the sphenoid sinus. Only 3-4% of CSF fistulas are spontaneous. The fourth case is presented of a CSF rhinorrhea due to a transclival meningocele, an extremely rare location for these lesions, and the surgical approach. The patient is a 39-year-old male with no history of trauma, and a recent history of watery rhinorrhe and meningitis. CT scan and MRI showed clival bone defect and trans-sphenoidal transclival meningocele. The defect was repaired by transclival trans-sphenoidal endoscopic endonasal approach with good results. Despite the rarity of transclival meningocele, it is recommended to consider it in the differential diagnosis of spontaneous nasal fistulas. The endoscopic endonasal approach is a direct technique that provides satisfactory results in the resolution of CSF rhinorrhea

RESUMO

Introducción: Las complicaciones intratorácicas secundarias a la colocación de una derivación ventriculoperitoneal son infrecuentes, aunque se asocian a graves consecuencias si no son tratadas de forma adecuada. Caso clínico: Describimos un caso de migración intratorácica de un catéter peritoneal tras derivación ventriculoperitoneal y se revisan las escasas referencias en la literatura, con discusión de los posibles mecanismos de penetración en la cavidad torácica. En ninguno de los artículos publicados se describe la presencia de un paciente con estereotomía previa como en nuestro caso. Conclusión: Es recomendable que tras el diagnóstico de la migración descrita, se proceda a un tratamiento precoz de reposicionamiento del catéter que evite complicaciones posteriores de mayor relevancia. Asimismo, durante la colocación de una derivación ventriculoperitoneal destacamos la importancia de la palpación permanente del catéter durante la tunelización subcutánea para evitar la migración intratorácica del mismo


Background: The intrathoracic complications from ventriculoperitoneal shunt placement are very rare. However, they are potentially serious if not treated. Clinical case: We report the case of thoracic migration of a peritoneal catheter after ventriculoperitoneal shunt and we also review the literature references with discussion of the different mechanisms of shunt-tip migration described. No case of previous sternotomy as in our patient has been found published. Conclusion: All reports recommend early catheter repositioning into the peritoneal cavity after diagnosing the migration described, to prevent worse complications. Moreover, it is important to keep in mind that intrathoracic migration can happen and it is necessary to palpate the catheter continuously during passage through subcutaneous tunnelling to prevent it

RESUMO

INTRODUCCIÓN: El tumor glioneuronal formador de rosetas (TGFR) del cuarto ventrículo es un tumor infrecuente que ha sido recientemente caracterizado. Fue incluido como una nueva neoplasia glioneural en el ańo 2007 por la Organización Mundial de la Salud (OMS) en la clasificación de tumores del sistema nervioso central. Dentro de este grupo hemos encontrado 34 casos documentados. En este artículo presentamos un nuevo caso de TGFR del cuarto ventrículo con hemorragia intratumoral postraumática y revisamos la literatura existente de esta nueva entidad. CASO CLÍNICO: Paciente de 30 ańos que tras sufrir traumatismo craneoencefálico leve presentó cefalea, diplopía y ataxia. Los estudios de tomografía computarizada y resonancia magnética cerebral revelaron una tumoración a nivel del cuarto ventrículo con sangrado intralesional y áreas de calcificación. La paciente fue intervenida realizándose extirpación tumoral macroscópicamente completa. El estudio anatomopatológico mostró un tumor glioneuronal formador de rosetas del cuarto ventrículo. CONCLUSIONES: Los TGFR del cuarto ventrículo son raros y afectan a adultos jóvenes. La evidencia demuestra que el pronóstico suele ser favorable, pero existe la posibilidad de progresión y recidiva. La hemorragia intratumoral es una forma de presentación muy poco habitual que implica riesgo para la vida del paciente. La resección quirúrgica debe ser cuidadosa debido a la localización de estas lesiones y su extensión hacia zonas críticas. Todos los pacientes, independientemente del grado de resección logrado, precisan un seguimiento a largo plazo por el riesgo de recidiva tardía


INTRODUCTION: Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle is a rare tumor that has been recently characterized. RGNT was included as a new glioneuronal tumor in 2007 by the World Health Organization (WHO) in classification of tumors of the central nervous system. Within this group we found 34 documented cases. We present a new case of RGNT of the fourth ventricle with intratumoral posttraumatic bleeding and review the existing literature of this new entity. CASE REPORT: A 30-year-old patient was admitted after suffering mild traumatic brain injury (TBI) had headache, diplopia and ataxia. Studies of computed tomography and magnetic resonance imaging revealed a tumor at the fourth ventricle with intralesional bleeding and areas of calcification. She was operated performing macroscopically complete tumor resection. Pathologic examination showed a rosette-forming glioneuronal tumor of the fourth ventricle. CONCLUSIONS: The RGNT of the fourth ventricle are rare and affect young adults. The evidence shows that the prognosis is usually favorable but there is the possibility of progression and recurrence. Intratumoral hemorrhage is a very unusual presentation that involves risk to the patient's life. Surgical resection should be careful due to the location of these lesions and their extension into critical areas, all patients regardless of extent of resection achieved require a long-term monitoring of the risk of late relapse

RESUMO

La paquimeningitis hipertrófica crónica (PHC) es un proceso inflamatorio de etiología desconocida que se caracteriza por afectar a la duramadre, provocando un crecimiento pseudotumoral de la misma. La clínica de presentación es consecuencia del efecto compresivo sobre estructuras neurológicas aunque en ocasiones se manifiesta por síntomas irritativos. El diagnóstico se realiza por exclusión de causas infecciosas, neoplásicas y autoinmunes fundamentalmente. El tratamiento esteroideo se considera la terapia más utilizada hoy en día. Se presentan 2 casos clínicos de PHC en los que se practicó resección quirúrgica de la lesión sin precisar posteriormente tratamiento coadyuvante dada la favorable evolución clínica y radiológica (AU)

RESUMO

Los angiomas venosos se consideran una anomalía del desarrollo caracterizada por persistencia en la edad adulta de un drenaje venoso embrionario. Suelen ser asintomáticos y de curso benigno, aunque pueden ocasionar convulsiones y menos frecuentemente hemorragias, normalmente por malformación cavernosa asociada. En la mayoría de los casos no es preciso tratamiento alguno, salvo circunstancias como sangrado, clínica intensa atribuible a la lesión y localización de buen acceso quirúrgico. Se presenta el caso de un varón de 11 años con un cuadro brusco de disminución del nivel de consciencia, objetivándose en estudios de imagen hematoma en hemisferio cerebeloso derecho, así como estructuras tubulares radiales compatibles con anomalía venosa del desarrollo. Se practicó una intervención quirúrgica con evacuación de hematoma, sin objetivarse otras causas que justifiquen el sangrado (AU)

RESUMO

Chronic hypertrophic pachymeningitis is an inflammatory process of unknown aetiology characterised by a thickening of the dura mater causing pseudotumoural growth. Clinical manifestations are usually secondary to compression of adjacent neurological structures but may be also secondary to inflammatory processes. Diagnosis is mainly obtained by excluding infectious, neoplastic and autoimmune causes. Nowadays, steroid treatment is the most commonly used therapy. Two clinical cases of hypertrophic pachymeningitis are presented which were treated by surgery without any additional treatment and with good clinical and radiological development.

RESUMO

Venous angiomas are a developmental anomaly in which embryonic venous drainage is still present into adulthood. They are usually asymptomatic and benign course but they can cause seizures and less commonly bleeding, usually associated to cavernous malformation. Normally, treatment is not necessary although bleeding, severe clinical and lesions in which it is possible a favourable approach, we can consider treatment. We show a case of a 11 years old boy with acute decrease level of consciousness. We observed hematoma in the right cerebellar hemisphere with radial tubular structures consistent with developmental venous anomaly. The hematoma was evacuated without a demonstrable other reason justifying the bleeding.
