RESUMEN

Paragangliomas are rare, benign and slow-growing neuroendocrine tumors that can arise from the adrenal medulla (85­90%) or from the extra-adrenal paraganglia. In the central nervous system (CNS), they can be found at several sites, but more often at the cauda equina and filum terminale region, where they account for between 2.5 and 3.8% of total tumor cases of that region. There are only 8 cases described in the literature that mention the presence of the gangliocytic variant of this entity at the filum terminale. We present the case of a 41-year-old man with chronic lumbar pain refractory to medical treatment, without any associated neurological deficits. Magnetic resonance imaging (MRI) revealed an intradural, extramedullar oval lesion with regular contours and homogeneous caption of contrast at L1 level. He was submitted to surgical treatment, with complete resection of the lesion. The histological analysis revealed a gangliocytic paraganglioma of the filum terminale. At 5 years of follow-up, he remains asymptomatic and without any signs of relapse. These are lesions with an overall good prognosis with gross total resection. Although the recurrence rate is extremely low, prolonged observation is recommended due to the slow-growing nature of the tumor, being estimated that between 1 and 4% can recur even after gross total removal.

RESUMEN

PURPOSE: Symptomatic Chiari type I malformation (CM) is treated with posterior fossa decompression with/ without duroplasty. Few authors suggested cerebellar tonsil caudal migration due to a supposed "caudal traction" of cranial nerve structures in a so-called occult tethered cord syndrome. For these authors, filum terminale (FT) sectioning may improve CM symptoms. The objective of this review is to evaluate the effect of FT sectioning on the treatment of CM. METHODS: Using the PRISMA guidelines for systematic reviews, we reviewed studies to evaluate patient's outcomes with CM who underwent FT sectioning. The MINORS instrument was used for methodological quality assessment. The included studies' levels of evidence (LOE) were classified according to the Oxford Centre of Evidence-Based Medicine. RESULTS: Two studies from the same group of authors were included. We cannot assure if the cited cases in the first study were also included in their latter published study. The described results suggest that outcomes were not collected in a standardized fashion. Outcomes are described vaguely as a percentage of improvement. Case series samples were small and included not only patients with CM but also patients with scoliosis and syringomyelia. The MINORS score reported that both studies had low methodological quality. Both included studies were classified as level 4 of evidence. CONCLUSION: There is no scientific support for filum terminale sectioning in patients with CM without evidence of tethered cord. This procedure may be considered experimental and should be validated in a strict criterion of inclusion clinical trial comparing outcomes in posterior fossa decompression.

RESUMEN

Background: Spinal neoplasms are classified into extradural, intradural/extramedullary or intramedullary. Intradural/extramedullary tumors include meningiomas and nerve sheath tumors, which arise from meninges or peripheral nerves around the spinal cord. Clinical signs are related to dysfunction of the involved nerve and include pain, nerve root signature and atrophy. Osteochondromas are benign tumors located within the bone, on its surface or in extra-osseous regions, when they are classified as soft tissue osteochondoma. The aim of this study is to describe a case of an osteochondroma in a nervous root of the cauda equina in a dog, whose surgical resection allowed the resolution of the clinical signs.Case: A 12-year-old, male, Labrador Retriever dog, was presented with a 40-day history of progressive, painful, pelvic limb paresis, with no improvement when treated with analgesics and acupuncture. Neurological abnormalities included paraparesis, sometimes worse in the left pelvic limb, that was carried flexed at the level of the stifle, hindlimb atrophy, decreased interdigital reflexes and pain in the lumbar spinal region, mainly over L6 vertebra. Results of blood count and serum biochemical analysis were unremarkable. Computed tomography (CT) of the lumbosacral area was performed and the evaluation of images in transverse and reconstructed dorsal and sagittal planes allowed the visualization of a hyperattenuating and calcified round structure with 8 mm x 6 mm, in the left side of vertebral canal, at the level of caudal epiphysis of L6. Lumbosacral (L7-S1) CT abnormalities, as subchondral sclerosis, mild disc margin bulging, spondylosis deformans and foraminal proliferation were also observed but were considered clinically insignificant.[...]

RESUMEN

Objetivou-se avaliar viabilidade, eficácia, vantagens e desvantagens da anestesia epidural lombossacral, junto à anestesia geral inalatória, em cirurgias de descompressão da cauda equina, tendo em vista que essas cirurgias são procedimentos longos e dolorosos. Para isso, foram utilizados 11 cães adultos com sinais clínicos de síndrome da cauda equina, que foram submetidos à anestesia geral inalatória e deixados no estágio anestésico mais superficial. Depois, realizou-se a anestesia epidural em seis dos 11 pacientes, por punção espinhal em L7-S1, com bupivacaína a 0,5 por cento. Os parâmetros fisiológicos (cardíacos, vasculares, respiratórios, temperatura corporal e glicemia) foram aferidos antes da medicação pré-anestésica, 10 minutos após esta, 30 minutos depois da epidural, depois da laminectomia, assim como após 60 minutos e 90 minutos da epidural, tanto no grupo com epidural como naquele sem esta (controle). Os animais que possuíam bloqueio epidural apresentaram redução significativa no consumo de anestésico inalatório e no tempo de extubação, não apresentando déficits neurológicos causados pela anestesia epidural, quando comparados com o grupo-controle. Conclui-se que a técnica de anestesia epidural é eficiente e vantajosa na realização de cirurgias descompressivas lombossacrais, pois proporciona menor risco anestésico para o animal.(AU)


The objective of this study was to evaluate the feasibility, effectiveness, advantages and disadvantages of lumbosacral epidural anesthesia with inhalational anesthesia in surgical decompression of the cauda equina, since this surgery has a lengthy and painful recovery from anesthesia. For this, 11 adult dogs which showed clinical signs of cauda equina syndrome were used. After the epidural, anesthesia in six of 11 patients, spinal tap in L7-S1, with bupivacaine 0.5 percent anesthetic was used. Physiological parameters (heart, vascular, respiratory and body temperature) were measured before, 10 minutes after, and 30 minutes after the epidural, after the laminectomia and 60 minutes and 90 minutes after the epidural, both in the epidural group and the control group. Animals that had ep showed a significant reduction in consumption of inhaled anesthetic and time of extubation. There were no neurological deficits caused by epidural anesthesia compared with the group without epidural anesthesia. It was concluded that the epidural anesthesia technique is effective in lumbosacral decompression surgeries, leading to a lower risk for the anesthetized animal.(AU)

RESUMEN

Objetivou-se neste trabalho avaliar a viabilidade, eficácia, vantagens e desvantagens da anestesia epidural lombossacral junto à anestesia geral inalatória em cirurgias de descompressão da cauda equina, tendo em vista que essa cirurgia é um procedimento longo e doloroso. Para isso, foram utilizados 11 cães adultos do atendimento de rotina do Hospital Veterinário, sem distinção de sexo, que apresentaram sinais clínicos de síndrome da cauda equina, diagnosticada através de exames neurológicos e radiográficos. Os cães foram submetidos à anestesia geral inalatória e deixados no estágio anestésico mais superficial. Depois, realizou-se a anestesia epidural em seis dos 11 pacientes, por punção espinhal em L7 -S1 , com o anestésico bupivacaína a 0,5%. Para a certificação do bloqueio foi realizado teste dos reflexos patelar e flexor, tônus muscular e dermátomos cutâneos, com os animais em plano anestésico superficial. Posteriormente, realizou-se a abordagem cirúrgica à coluna pela equipe de neurocirurgia. Os parâmetros fisiológicos (cardíacos, vasculares, respiratórios, temperatura corporal e glicemia) foram aferidos antes da medicação pré-anestésica (MPA), 10 minutos após a MPA, 30 minutos depois da epidural, depois da laminectomia, assim como após 60 minutos e 90 minutos, tanto no grupo com epidural quanto no sem epidural. Também se verificaram a quantidade de isofluorano consumido e o tempo de extubação. Os animais que possuíam bloqueio epidural apresentaram redução significativa no consumo de anestésico inalatório e no tempo de extubação. Não apresentaram déficits neurológicos causados pela anestesia epidural, quando comparados com o grupo sem anestesia epidural. Conclui-se que a técnica de anestesia epidural é eficiente e vantajosa na realização de cirurgias descompressivas lombossacrais, levando ao um menor risco anestésico para o animal.


The objective of this study was to evaluate the feasibility, effectiveness, advantages and disadvantages of lumbosacral epidural anesthesia associated with inhalation anesthesia in surgical decompression of cauda equina, seeing as this is a lengthy procedure with a painful recovery from anesthesia. Eleven adult dogs were selected from the Veterinary Hospital, without distinction of sex, which showed clinical signs of cauda equina syndrome, diagnosed by neurological examination and radiographs. The dogs were submitted to general inhalation anesthesia and left at a superficial stage, after which epiduralanesthesiawithbupivacaine0.5% via spinal tapinL7-S1was performed in six of11patients. To confirm epidural block, the patellar and flexor reflexes were tested, along with evalluation of muscle tone and skin dermatomes, with the animals in a superficial anesthetic plane. The approach to spinal column was then performed by the neurosurgery team. Physiological parameters(heart, vascular, respiratory and body temperature) were measured before the preanesthetic medication, 10 minutes after, 30 minutes after epidural block, after opening the spine and 60 minutes, 90 minutes, both in the animals with and without an epidural. The amount of isoflurane used and time to extubation were also noted. Animals that had epidurals showed a significant reduction in the consumption of isoflurane and time until extubation. There were no neurological deficits caused by the epidural anesthesia when compared with the group without epidural anesthesia .It was concluded that epidural anesthesia is effective in lumbosacral decompression surgeries, leading to a lower anesthetic risk for the animals.

RESUMEN

The majority of the filum terminale ependymomas are of the myxopapillary type, which most commonly present as lumbago or sciatic pain, an insidious clinical condition, at times accompanied by paraparesis, bladder paresis and vesical alterations. We report the case of a 13-year-old patient who presented with acute cauda equina. He underwent total resection of the lesion, which resulted in progressive improvement. The clinical conditions, diagnoses and treatments of the medullary cone and cauda equina myxopapillary ependymomas are also discussed.

RESUMEN

Filum terminale ependymomas are slow growing tumors of the cauda equina with a high incidence in young adults. Although a complete microsurgical resection can lead to a cure, recurrence is not uncommon. Sixteen cases of filum terminale ependymomas treated at the Instituto de Neurologia de Curitiba were analyzed. Eleven patients were females and 5 males, their age ranging from 7 to 84 years. Symptoms and signs included lumbar pain (31.25%), radicular pain (56.25%) and neurological deficits (12.5%). In three cases, patients had previously undergone surgery in other hospitals. All were tested through MRI and were operated on. Two underwent a laminoplasty and 14 a laminectomy. The last 8 patients of this series had neuro-physiological monitoring during surgery. In all patients a total microsurgical resection was achieved. Histologically, 2 cases were cellular ependymomas and 14 cases myxopapillary ependymomas. There was no recurrence during a 2 to 84 month follow-up period.

Os ependimomas do filum teminale são tumores da cauda eqüina de crescimento lento com maior incidência em adultos jovens. A ressecção microcirúrgica total possibilita a cura da doença, recidivas, entretanto, apresentam sérias dificuldades no tratamento. Com o objetivo de estudar os aspectos clínicos, anatomopatológicos e do tratamento, analisaram-se 16 casos de ependimomas do filum teminale tratados no Instituto de Neurologia de Curitiba, 11 do sexo feminino e 5 do sexo masculino, com idade entre 7 e 84 anos, que apresentavam dor lombar (31,25 por cento), radiculopatia (56,25 por cento) e déficits neurológicos (12,5 por cento). Em 3 casos, os pacientes tinham sido operados em outro serviço anteriormente. Em todos os casos o diagnóstico foi confirmado pela ressonância magnética. Em 2 pacientes realizou-se laminoplastia e em 14 laminectomia. Nos últimos 8 pacientes empregou-se monitorização neurofisiológica. Em todos os casos a ressecção microcirúrgica foi total. Do ponto de vista histológico, demonstraram-se 2 casos de ependimoma celular e 14 casos mixopapilares. Não houve recidiva do tumor em um seguimento entre 2 e 84 meses.

RESUMEN

OBJECTIVE AND IMPORTANCE: Intravascular papillary endothelial hyperplasia (Masson's vegetant hemangioendothelioma) is a rare condition affecting the neuraxis. In the literature, only one case of this lesion involving the vertebral canal with spinal cord compression has been reported. We present a case of cauda equina compression due to this abnormality. CLINICAL PRESENTATION: A 17-year-old boy was admitted at our hospital with pain, numbness, paresis of the left lower extremity, and bladder dysfunction of approximately 1 month's duration. Computed tomography and magnetic resonance imaging of the spine revealed a tumor within the spinal canal at the T12-L1 level. INTERVENTION: The patient underwent a T12-L1 laminectomy. An epidural red nodular tumor was visualized and totally resected. The findings of the pathological examination were compatible with intravascular papillary endothelial hyperplasia. At follow-up examination 1 month after the operation, the patient had complete resolution of the pain, and the motor deficit and bladder dysfunction had improved significantly. CONCLUSION: This rare benign vascular lesion may be clinically and histopathologically mistaken for an angiosarcoma. Because the intravascular papillary endothelial hyperplasia can be cured by complete surgical resection, it is important to distinguish between these two lesions to avoid inappropriate aggressive treatment.

RESUMEN

Os resultados do tratamento de 50 doentes através do método da neuroestimulaçao da medula espinal sao apresentados. A dor foi decorrente de lesao traumática do cone medular e das raízes da cauda eqüina em 8 doentes, lesao da medula espinal em 14, neuropatia pós-herpética em 6, distrofia simpático-reflexa em 8, fibrose peridural em 6, doença oncológica em 1, avulsao das raizes do plexo braquial em 4 e decorrente da amputaçao de membros em 3 (dor em membro fantasma em 2 e no coto de amputaçao em 1). Os resultados foram considerados bons e excelentes, durante o período de seguimento, em 26 doentes (52 por cento). Vinte e quatro (48 por cento) nao se beneficiaram com a estimulaçao elétrica da medula espinal. Em 2 doentes o sistema implantado teve que ser removido devido a infecçao. Um dos doentes apresentou complicaçoes transitórias decorrentes de síndrome cordonal posterior. A estimulaçao elétríca da medula espinal nao contribuiu para o alívio da dor em 7 doentes com lesao traumática da medula espinal e raízes da cauda eqüina. Um doente teve excelente resultado após o implante; entretanto, observou-se recorrência da dor durante o acompanhamento clínico.Em 7 doentes com mielopatia, o resultado satisfatório obtido com o implante permaneceu durante o período de seguimento (mediana de 8,9 meses). Em doentes com nevralgia pós-herpética foram observados resultados bons e excelentes após o ato operatório; no entanto, foram observadas recorrência parcial da dor em l e recorrência total em outro. Dentre os 7 doentes com distrofia simpático-reflexa, a estimulaçao da medula espinal resultou no alívio imediato e persistente da sintomatologia em 6. Um doente apresentou recorrência da dor. A estimulaçao elétrica da medula espinal propiciou alívio imediato da dor em 2 doentes com avulsao das raizes do plexo braquial. Entretanto, a dor recorreu em 1.Um doente com dor no coto de amputaçao e 2 com dor no membro fantasma nao apresentaram alívio com estimulaçao elétrica da medula espinal. O doente com dor oncológica visceral apresentou resultado satisfatório durante os 2 últimos meses de vida.Baseado na análise deste trabalho, é possível concluir que a estimulaçao elétríca da medula espinal é especialmente recomendada para o tratamento das síndromes neuropáticas com lesao mínima ou parcial das estruturas nervosas, como as que ocorrem em casos de distrofia simpático-reflexa, radiculopatias ou lesao parcial da medula espinal.

RESUMEN

Se comunican dos casos de pacientes con síndrome de silla de montar, posterior a anestesia peridural continua. Uno de ellos es un caso consecutivo de resección transureteral de la próstata (RTU) y el otro consecutivo a RTU papiloma vesical y hernioplastia inguinal. La técnica de anestesia raquídea o peridural continua se ha usado desde hace muchos años. El síndrome de silla de montar se ha comunicado en la literatura como una complicación de la anestesia raquídea. Los casos aquí comunicados posiblemente sean los dos primeros que se informan con este síndrome, utilizándose anestesia peridural continua
