ABSTRACT

BACKGROUND: Intraventricular meningiomas are rare tumours that represent about 2% of all intracranial meningiomas, and represent one of the most challenging problems in neurosurgery. They are located deep within the brain and often are sizable and highly vascular. We report on a series of 10 meningiomas of the lateral ventricles treated at our institution during the last 28 years. PATIENTS: Ten patients (6 women, 4 men; mean age 41.6 yrs) were admitted to our medical center between 1978-2005 with meningioma of the lateral ventricles. Headache was the first symptom in 8 cases and ocular signs were present in 5 patients. RESULTS: Seven tumours were located in the right ventricle (70%) ranging in size from 2-8 cm, with 7 tumours larger than 3 cm in diameter. Nine patients underwent surgery with total excision in 8 cases and subtotal in the other; the remaining patient only received radiosurgery. CONCLUSIONS: Total resection is the gold standard for treatment which was possible in all but one of the cases undergoing surgery.

ABSTRACT

OBJECTIVE: To present the incidence, clinical presentation, radiological features, localization, surgical techniques, and long term results of surgically treated spinal meningiomas. PATIENTS AND METHODS: We review retrospectively 57 spinal meningiomas in 55 patients operated between January 1980 and June 2004. Age, sex, duration and type of symptoms, radiological and surgical results, histological features and long term outcome are analyzed. RESULTS: Fifty five patients, consisting 46 females and 9 males, with an age range from 12 to 84 years (mean 65.2+/-9.2) were identified. The first symptom was motor deficit (N=34, 61.8%) and the mean duration symptoms were: 6.2 months. Distribution along the spinal axis was 51 thoracic, 5 cervical and 1 lumbar. The most common type was meningothelial (N=31, 54.3%). CONCLUSIONS: Meningiomas account in our experience, the 46% of spinal cord tumours and account the 7.5% of all meningiomas. They are more frequent in females most frequently occur in the thoracic region and have low recurrence rate. Typically, they are located in the intradural extramedullary space, grow slowly, and spread laterally in the subarachnoid space. Finally we concluded that magnetic resonance imaging is the best imaging technique for diagnosis and total tumour resection improved the surgical results of spinal meningiomas.

ABSTRACT

Objetivos. Analizar la incidencia, presentación clínica, hallazgos radiológicos, localización, tratamiento y resultados operatorios de los meningiomas espinales. Pacientes y método. Estudio retrospectivo sobre 57meningiomas espinales en 55 pacientes operados entre Enero de 1980 y Junio de 2004. Analizamos la edad, sexo, síntomas de debut y duración de los mismos, características radiológicas, técnica quirúrgica, estudios histológicos y resultados. Resultados. La serie consta de 55 pacientes (46 mujeres y 9 varones), con edades comprendidas entre 12 y 84años (media 65.2±9.2). El síntoma de debut más frecuentes fue el déficit motor en 34 casos (61.8%) y la duración media de la sintomatología antes del diagnóstico de 6.2meses. La distribución a lo largo del raquis mostró 51casos en la región dorsal, 5 cervicales y 1 lumbar. El tipo histológico más frecuente fue el meningotelial (N=31,54.3%).Conclusiones. Los meningiomas espinales constituyen en nuestra experiencia el 46% de todos los tumores intradurales extramedulares y el 7.5% de todos los meningiomas. Afectan sobre todo a mujeres y en la mayoría de los casos se ubican en la región dorsal. Su localización habitual es intradural extramedular y se desarrollan lentamente extendiéndose lateralmente por el espacio sub aracnoideo. La resonancia magnética es la técnica diagnóstica de elección y la resección quirúrgica completa conduce a una recuperación total en la mayoría de los casos

ABSTRACT

INTRODUCTION: Epidural haematomas are one of the most common complications of closed head injuries. Bilateral extradural haematomas are rare, usually acute, and generally associated with severe trauma and a high mortality. OBJECTIVE: The purpose of this paper is to present six cases of bilateral extradural haematomas seen at our service during the last 24 years and found an incidence of 2.5% of all cases of extradural haematomas surgically treated. RESULTS: There were 5 males and 1 female with a mean age of 32.6 years (range 16-55). In 3 cases haematoma was across the midline and in the other 3 cases haematomas was found at different locations on either side. Skull fracture was present in all cases. Surgical approach was the primary treatment in all cases. Mortality in our series was 50%. CONCLUSIONS: Bilateral extradural haematomas is a rare condition and the prognosis is mainly dependent of the pre-operative neurological state.

ABSTRACT

Introducción. Los hematomas epidurales constituyen una de las complicaciones más frecuentes de los traumatismos craneales. Los hematomas bilaterales son muy poco frecuentes, se asocian a traumatismos de gran intensidad y se acompañan de una elevada mortalidad. Objetivos. Analizar los 6 casos de hematoma epidural bilateral (HEB) tratados en los últimos 24 años que representan el 2.5% de todos los hematomas epidurales intervenidos quirúrgicamente en el mismo período de tiempo. Resultados. La serie está formada por 5 varones y 1 mujer con una edad media de 32.6 años (rango 16-55). Clínicamente todos presentaban disminución del nivel de consciencia. En 3 pacientes el hematoma sobrepasaba la línea media, y en los otros 3 las localizaciones eran diversas. Se apreció fractura de cráneo en la totalidad de los pacientes. Todos los hematomas fueron tratados quirúrgicamente y la mortalidad operatoria fue del 50%. Conclusiones. El hematoma epidural bilateral es una entidad clínica poco frecuente y cuyo pronóstico depende fundamentalmente de la situación neurológica preoperatoria

ABSTRACT

Objetivos. Realizar un estudio sobre los casos de empiema epidural espinal atendidos en los últimos 20 años y practicar una revisión de la literatura sobre la patogenia, diagnóstico y tratamiento de estas lesiones. Pacientes y métodos. Se trata de un estudio retrospectivo descriptivo sobre 14 casos de empiemas epidurales espinales. Se analizaron las características epidemiológicas básicas, manifestaciones clínicas, datos analíticos, técnicas de diagnostico, actitudes terapéuticas usadas y los resultados obtenidos. Resultados. La serie esta formada por 7 varones y 7 mujeres con edades que oscilaron entre 8 y 76 años (media 48.9). En 12 casos el síntoma de presentación fue la presencia de dolor vertebral local, siempre en relación con la localización del empiema, siendo la duración media de la sintomatología de 9.3 días. La velocidad de sedimentación globular (VSG) estaba elevada en todos los casos y existía leucocitosis en trece paicentes (92,9%). En 11 casos (78,5%), la localización del empiema fue en la región dorsal. Trece pacientes fueron tratados mediante cirugía y uno recibió exclusivamente tratamiento antibiótico. Conclusiones: En paicentes con factores de riesgo (inmunosupresión, diabestes), la presencia de dolor espinal asociado a fiebre y alteraciones analíticas (leucocitosis / elevación de la VSG), deben ser con resonancia magnética espinal, ante el riesgo de desarrollar un empiema epidural. El tratamiento exclusivamente médico debe sólo reservarse para pacientes con elevado riesgo quirúrgico o que no presenten afectación neurológica (AU)


Objective. The goal of this study was to review our series of spinal epidural empiema diagnosed in the last 20 years and review the literatura regarding the pathogenesis, diagnosis and treatment of these lesions. Patints and methods. This is a retrospective study over 14 patients diagnosed of spinal epidural empyema. We review the epidemiological data, clinical symptoms, laboratory and imaging data, the treatment regimen and the results. Results. Fourteen patients, 7 males and 7 females, with an age range form 8 to 76 years (mean 48.9) were identified. The first symptom was localized back/neck pain in 12 patients and the mean duration of symptoms was 9.3 days. Erythrocyte sedimentation rate (ESR) was elevated in 13 cases (92,9%). Site of sipinal epidural empyemas was distributed along the axis but in 11 cases the location was thoracic. Thirteen patients had surgery for debridement and spinal decompression and one patient was treated successfully with antibiotics alone. Conclusions: Patients with localized back pain and fever who are at risk for developing such empyemas with elevation of white blood cells and increased ESR, should have an immediate magnetic resonance imaging sean. Urgent surgical drainage and antibiotic use are the treatment of choice in order to prevent irreversible neurological deficits. Nonsurgical treatment should be reserved for poor surgical candidates and patients without neurological deficits (AU)

ABSTRACT

Encephalocele is defined as a protrusion of cranial contents beyond the normal confines of the skull. Encephaloceles occur with an incidence of approximately 1 in 3,000-10,000 births and are categorized based on location in the skull. Orbital meningoencephalocele is a rare congenital abnormality caused by a defect of the cranio-orbital bones that usually manifests soon after birth as a soft mass associated with exophthalmos. We present a case of a giant orbital meningocele presenting as an orbital mass in a 15 months-old girl. Preoperative diagnosis was confirmed by CT-scan and magnetic resonance imaging.

ABSTRACT

Los cefaloceles son extrusiones de contenido intracraneal a través de defectos óseos en el cráneo. Su incidencia aproximada es de un caso por cada 3000-10.000 recién nacidos y se clasifican en función de su localización en el cráneo. Los meningoceles orbitarios son muy poco habituales y se manifiestan con la presencia de una masa intraorbitaria de consistencia blanda que provoca exoftalmos. Presentamos el caso de una niña de 15 meses afecta de un voluminoso meningocistocele orbitario, que se presentó al nacimiento como una masa orbitaria y que fue diagnosticada con tomografía computarizada y resonancia magnética (AU)

ABSTRACT

Intracranial epidermoid tumours are very rare lesions of ectodermal origin that account for 1% of all intracranial tumours. The favourite sites affected by these tumours are the cerebellopontine angle and the chiasmal region. They also appear in the cerebral hemisphere and the intraventricular cavities. We report a case of epidermoid tumour of the third ventricle. The patient was a 68 year-old woman admitted in our service with a 7-days history of headaches and intermittent nausea and vomiting. A CT scan of the brain revealed a large hypodense mass in the third ventricle associated with hydrocephalus. An MRI was performed and revealed, on T1-weighted image, an irregular nonhomogeneous lower signal in relation with CSF. This tumour showed a very bright signal intensity on T2-weighted images. A transcallosal approach of the tumour mass was performed via a right frontal craniotomy. Using an ultrasonic aspirator, the tumour was removed. In a review of the literature, we found only 8 reported cases.

ABSTRACT

Los quistes epidermoides intracraneales son tumoraciones de origen ectodérmico que representan menos del 1 por ciento de los procesos expansivos intracraneales. Las localizaciones más frecuentes son en el ángulo pontocerebeloso y la región quiasmática, aunque también se localizan en los hemisferios cerebrales o en las cavidades ventriculares. Presentamos el caso de una mujer de 68 años ingresada por presentar una historia de 7 días de evolución de dolor de cabeza acompañada de náuseas y vómitos intermitentes. La tomografía computarizada mostró una masa hipodensa localizada en el tercer ventrfculo asociada a hidrocefalia moderada. En resonancia magnética la tumoración se presentaba como hiposeñal en T1 e hiperseñal en T2. Empleando un abordaje transcalloso se realizó con ayuda del aspirador ultrasónico una exéresis completa. En la revisión de la literatura únicamente hemos encontrado otros 8 casos de quistes epidermoides localizados en el tercer ventrfculo (AU)

ABSTRACT

Introducción. Los ependimomas son tumores de origen ependimario que se localizan en las cavidades ventriculares y la médula espinal. Los ependimomas intracraneales representan entre el 2 y 6 por ciento de los tumores del sistema nervioso central y la mitad de ellos aparecen en las dos primeras décadas de la vida. Desarrollo. Realizamos una revisión sobre la epidemiología, clínica, hallazgos histopatológicos, diagnóstico neurorradiológico y tratamiento de los ependimomas intracraneales. Conclusiones. Los ependimomas infratentoriales son más frecuentes en niños mientras que los supratentoriales predominan en el adulto. Del análisis de la literatura se concluye que la cirugía radical es el tratamiento de elección en estos tumores. La supervivencia guarda relación con la extensión de la exéresis practicada, el grado histológico y la edad del paciente (AU)

ABSTRACT

INTRODUCTION: Ependymomas are tumours derived from ependymal cells, found lining the cerebral ventricles and central canal of spinal cord. Intracranial ependymomas account for 2 6% of all neoplasms of the central nervous system and at least half present in the first two decades of life. DEVELOPMENT: We review the epidemiological, clinical, neuropathological details, neuroradiological aspects and treatment of intracranial ependymomas. CONCLUSIONS: Ependymomas of the posterior fossa predominate in children, while supratentorial tumours are more common in adults. This analysis of the literature further highlight that total tumour removal is the treatment of choice for intracranial ependymomas. Postoperative survival was predominantly dependent on the histological grade of malignancy, the extension of surgery and the age of the patient.

ABSTRACT

Adenocystic carcinomas are malignant tumours that arise from the major accessory salivary glands. Cutaneous involvement can result from direct extension from a salivary gland neoplasm. Cutaneous adenocystic carcinomas remote from adjacent salivary tissue are rare. We present the case of an elderly patient with primary cutaneous adenoid cystic carcinoma causing spinal cord compression at the L1-L2 level. The patient was operated on and the tumour totally removed. No similar cases have been found in our review of the literature.

ABSTRACT

We describe a rare case of an intradural spinal chordoma. Only two cases have been previously reported and it is the second case diagnosed with MRI. A 65-year-old man presented with progressive disturbance of gait and weakness in the lower extremities. MRI revealed a intradural C6-C7 isointense mass, on T1- and T2-weighted images. The lesion enhanced after injection of gadolinium. The lesion was totally removed without difficulty by a C6-D1 laminectomy. Microscopic examination of the tumor revealed a chordoma. This is the third case in the literature of an intradural spinal chordoma. The appearance of this tumor with MRI may be similar to the chordomas of other locations.

ABSTRACT

Solitary abscesses of the thalamus are an infrequent entity which carry serious problems with regard to treatment. We present a patient with an unknown septic focci who developed a right thalamic abscess due to Streptococcus constellatus and was treated by stereotaxic drainage for the suppuration and antibiotics. The patient was clinically and radiologically (CAT) controlled up until total cure of the lesion. Complications included dissemination of the infection to the meningeal space and a residual coreic picture controlled with tetrabenzine. The authors believe that evacuation by stereotaxic punction should be included among the therapeutic options available for deeply localized cerebral abscesses.
