ABSTRACT

Los osteocondromas son tumores óseos benignos de lento crecimiento que se localizan habitualmente en los huesos largos. Aproximadamente el 1-4% de ellos se localizan en la columna vertebral. Los osteocondromas espinales solitarios pueden producir una gran variedad de síntomas, dependiendo de su localización y de su relación con las estructuras adyacentes. Recogemos el caso de una paciente de 74 años que fue ingresada en nuestro centro tras referir debilidad progresiva en el hemicuerpo izquierdo y dolor cervical. La exploración neurológica mostró hemiparesia izquierda leve y tortícolis izquierda. Los estudios de tomografía computarizada y resonancia magnética de la columna cervical demostraron una lesión expansiva afectando la articulación facetaria C3-C4 izquierda. Se realizó una hemilaminectomía C3 y C4, resección completa de la lesión y fijación cervical posterior instrumentada. El estudio anatomopatológico confirmó el diagnóstico de osteocondroma. Tras la intervención quirúrgica, los síntomas de la paciente mejoraron progresivamente sin secuelas neurológicas


Osteochondromas are slow-growing benign bone tumors that are located frequently in the long bones. Approximately 1-4% of them occur in the spine. Solitary spinal osteochondromas may produce a wide variety of symptoms depending on their location and relationship to associated structures. We report a case of a 74-year old woman who was admitted to our hospital with complaints of progressive left hemibody weakness and cervicalgia. Neurological examination disclosed mild left-sided hemiparesis and left torticollis. Computed tomography and magnetic resonance imaging of the cervical spine revealed an expansive lesion affecting the left C3-C4 facet joint. The patient underwent a posterior C3 and C4 hemilaminectomy, complete excision of the lesion and instrumented posterior cervical fixation. Histological examination confirmed the diagnosis of osteochondroma. After surgery her symptoms improved progressively with no neurological sequels

ABSTRACT

El pseudotumor retroodontoideo es una lesión provocada por granulación inflamatoria o por hipertrofia de partes blandas asociado a inestabilidad atloaxoidea crónica. Sin embargo, cerca de un tercio de los casos recogidos en la literatura no demostraron claramente esta inestabilidad. Los autores exponen el caso de un hombre de 76 años, previamente diagnosticado de hiperostosis esquelética idiopática difusa, que presenta un cuadro de mielopatía severa progresiva. Las imágenes de resonancia magnética de la columna cervical mostraron una masa predural retroodontoidea con compresión marcada del cordón medular. Se realizó laminectomía del atlas y fusión occipitocervical. Tras la cirugía el paciente mejoró significativamente y se redujo el tamaño del pseudotumor


Retro-odontoid pseudotumors are lesions caused by inflammatory granulation or reactive soft tissue hypertrophy from chronic atlantoaxial subluxation. However, one-third of the cases reported in the medical literature did not show atlantoaxial instability clearly. The authors present the case of a 76-year-old man previously diagnosed with diffuse idiopathic skeletal hyperostosis who presented with severe progressive myelopathy. A magnetic resonance imaging of his cervical spine revealed a retro-odontoid predural mass, which caused a severe compression of the cervical spinal cord. The patient underwent a posterior laminectomy of the atlas and an occipitocervical fusion. After surgery, the pseudotumor was considerably smaller and the neurological symptoms improved

ABSTRACT

Introducción. Los subependimomas intracraneales son tumores benignos poco frecuentes, no invasivos y de lento crecimiento. Se localizan habitualmente en el cuarto ventrículo. La mayor parte de estos tumores se descubre incidentalmente como pequeñas lesiones durante la realización de estudios de autopsia. Los estudios con técnicas de neuroimagen han incrementado su diagnóstico. En los casos de pacientes sintomáticos con subependimomas, estos síntomas habitualmente se deben a la obstrucción del líquido cefalorraquídeo o por efecto masa. Caso clínico. Varón de 52 años que presentaba cefalea intensa y deterioro cognitivo con alteraciones de memoria y bradipsiquia. Las imágenes de tomografía computarizada y de resonancia magnética mostraron una lesión en el ventrículo lateral derecho que provocó hidrocefalia obstructiva. El tumor fue resecado totalmente a través de un abordaje frontal transcortical derecho. El examen histológico demostró hallazgos de subependimoma típico. Tras la cirugía, se consiguió una recuperación neurológica completa. Conclusiones. Los subependimomas son neoplasias gliales poco frecuentes que habitualmente crecen dentro del sistema ventricular. Tienen un bajo potencial proliferativo, pero en estas localizaciones pueden provocar hidrocefalia sintomática. La resección quirúrgica de la lesión y la restauración de las vías normales de circulación del líquido cefalorraquídeo constituyen la estrategia terapéutica óptima (AU)


Introduction. Intracranial subependymomas are rare, slow-growing, noninvasive, benign tumors. They are most often located in the fourth ventricle. Most of these tumors are discovered incidentally during autopsy. Routine medical checkups using neuroimaging techniques have increased their diagnosis. Subependymomas may present with symptoms related to cerebrospinal fluid obstruction or mass effect. Case report. A 52-year-old man presented with severe headache and mental deterioration with memory disturbances and bradypsychia. Computed tomography and magnetic resonance imaging revealed a mass in the right lateral ventricle causing obstructive hydrocephalus. The tumour was totally removed through a right frontal transcortical approach. Histological examination showed a typical subependymoma. A complete neurological recovery was achieved after surgery. Conclusions. Subependymomas are rare low-grade glial neoplasm that commonly arise in the ventricular system. They have a low-proliferative potential but in these locations they can cause symptomatic hydrocephalus. Surgical removal of the mass and the restoration of the normal cerebrospinal fluid pathways constitute the optimal management strategy (AU)

ABSTRACT

La estimulación cerebral profunda es una técnica quirúrgica que ha alcanzado un importante desarrollo para el tratamiento de diferentes trastornos del movimiento como la enfermedad de Parkinson, el temblor o la distonía. Debido al importante crecimiento en el número de pacientes tratados, se han publicado cada vez con mayor frecuencia nuevas complicaciones de la cirugía. El bowstringing se define como una tensión anormal de las extensiones eléctricas situadas entre los electrodos y la batería, acompañada de una sensación de dolor y tensión a nivel cervical, en la zona donde se encuentran los cables. Presentamos el caso clínico de una mujer de 56 años con enfermedad de Parkinson que fue tratada con la implantación bilateral de electrodos subtalámicos. Después de un accidente de tráfico presentó ruptura del electrodo derecho, que fue recambiado. Seis meses más tarde acude por dolor y tensión en el cuello. Fue necesario realizar un abordaje cervical a los cables para extirpar el tejido cicatricial que se había formado .El bowstringing es una complicación poco habitual en este tipo de cirugía, y aunque algunos pacientes refieren molestias y tensión en el cuello, pocas veces es necesario su abordaje quirúrgico (..)

ABSTRACT

Deep brain stimulation (DBS) is an established surgical therapy for intractable movement disorders, such as Parkinson's disease, essential tremor and dystonia. As the number of treated patients has increased rapidly, new sets of problems about complications of DBS have arisen. Bowstringing is defined as abnormal tethering of leads between the pulse generators and stimulating electrode, associated with pain and contracture of the neck over the extension cable. We report the case of a 56-year-old woman with a history of advanced Parkinson's disease who had been treated by implantation of a bilateral, subthalamic nucleus, deep brain stimulator. A car accident caused the rupture of the right electrode, which was replaced. Six months after the replacement the patient presented disabling pain and tension in the neck where deep brain extension cables were located. A cervical incision was performed to excise scar tissue. Bowstringing is a rare complication of DBS and although patients sometimes report discomfort and tension in the cervical region, surgical procedures are not normally required.

ABSTRACT

INTRODUCTION: Primary bone lymphomas account for 3-7% of all malignant bone tumours and less than 2% of lymphomas in adults. Having the cranial vault as their primary location is very infrequent. CASE REPORT: A 59-year-old female who presented a painful tumour on the cranial vault which, following radical surgical removal, was found to be an ALK-negative primary large-cell lymphoma. CONCLUSIONS: After reviewing the literature we believe that this is the first case of cranial vault lymphoma in which the translocation of the ALK protein-producing gene has been studied.

ABSTRACT

Introducción. Los tumores de las vainas nerviosas representan alrededor del 30% de los tumores medulares del adulto. La mayoría son tumores solitarios que se pueden localizar en cualquier punto a lo largo del canal espinal, y cuando aparecen lesiones múltiples, se trata habitualmente de neurofibromas en el contexto de una enfermedad de von Recklinghausen. Objetivo. Analizar las características clínicas y radiológicas, el tratamiento y la evolución de una serie de pacientes con tumores de las vainas nerviosas espinales. Pacientes y métodos. Estudio retrospectivo sobre los pacientes intervenidos de tumores de vainas nerviosas espinales en un período de 25 años. Analizamos la edad, sexo, sintomatología, hallazgos de exploración física, estudios radiológicos practicados, localización del tumor y resultados quirúrgicos. Resultados. La serie consta de 35 varones y 33 mujeres, con una media de edad de 55 años (rango: 12-76 años). El dolor local o radicular fue el primer síntoma en 55 pacientes (80,8%). En 49 casos (66,2%), el tumor estaba localizado en la región lumbosacra, 15 casos eran dorsales (20,2%) y 10 cervicales (13,6%). La exéresis fue completa en 70 tumores (94,5%) y subtotal en 4 (5,5%). Histológicamente, 66 tumores (89,1%) fueron neurinomas, y 8 (10,9%), neurofibromas. Conclusiones. Los tumores de las vainas de las raíces espinales pueden presentarse en cualquier lugar del canal espinal, predominando en la región lumbosacra. La mayor parte de los pacientes comienza con dolor local o radicular, y en la mayoría de los casos es posible la resección completa del tumor con una buena recuperación funcional (AU)


Introduction. Spinal schwannomas account for about 30% of intradural spinal cord tumors in adults. More are solitary tumors, which can occur throughout the spinal canal. The multiple form of neurofibromas is known as von Recklinghausen disease. Aim. To analyze clinical and radiologic characteristics, treatment and evolution of patients with spinal nerve sheath tumor. Patients and methods. This was a retrospective study in a series of patients treated surgically of spinal schwannomas during 25 years. The following variables were evaluated: gender, age, symptomatology, radiological findings, localization, surgical findings and results. Results. We treated 35 male and 33 female with a mean age of 55 years (range: 12-76 years).The most common presurgical symptom was local or radicular pain in 55 patients (80.8%). In 49 cases (66.2%), the tumor was sited in the lumbosacral, in 15 cases (20.2%) in the dorsal tract, and in 10 cases (13.6%) in the cervical tract. Total removal was achieved in 70 cases (94.5%) and subtotal resection in 4 (5.5%). 66 tumors (89.1%) were schwannomas and the other 8 cases (10.9%) neurofibromas. Conclusions. Tumors of the spinal root sheaths can occur at any level of the spinal canal. Most patients present with local and/or radicular pain and in most cases total resection its possible with good functional recovery (AU)
