RESUMO
A 4-year-old girl was admitted to the emergency department after having been buried beneath a wall. A computed tomography scan revealed anterior grade V L5-S1 spondylolisthesis, and magnetic resonance imaging showed a traumatic rupture of the fibrous annulus of the L5-S1 intervertebral disc and lesion of the anterior longitudinal and yellow ligaments. The patient underwent anterior and posterior fixation. Four months later she was able to walk independently, despite a persistent left foot drop. Additionally, we conducted a literature review on lumbosacral spondyloptosis in the pediatric population published between 1990 and 2017. We found 16 cases, 86.6% of which were male, with a mean patient age of 16 ± 5.05 years. Most patients underwent spine instrumentation. Based on the data reviewed, the neurological status at admission might be a valid predictor of outcome. Pedicle screws are a safe and reliable procedure for stable fixation of the spine in these cases. The removal of screws is discouraged.

BACKGROUND: Hemichorea may point to a structural lesion in the contralateral basal ganglia with a large list of possible causes. Cavernous angioma may be rarely a possible cause for acute appearance of this movement disorder. CASE DESCRIPTION: We present a rare case of a 32-year-old female patient with hemichorea caused by a cavernoma (or cavernous angioma) in the contralateral insula and putamen with complete improvement of symptoms with surgical resection of the lesion. CONCLUSIONS: We believe that surgical resection of basal ganglia cavernomas may be feasible with minor risks and resolution of clinical symptoms in the immediate postoperative period.

BACKGROUND: Vestibular schwannoma (VS) is the most common benign tumor originating in the cerebellopontine angle. In most cases, tumors tend to grow and deserve proper treatment. Sometimes they stabilize, and rarely they decrease in size spontaneously. METHODS: We evaluated retrospectively the images of patients with spontaneous tumor regression. We describe the common neuroimage findings of patients with spontaneous tumoral regression. RESULTS: Four patients with diagnosis of VS were followed with magnetic resonance imaging (MRI). There were some relevant features in MRI: a heterogeneous contrast enhancement in the outer layer of the tumor and presence of a cerebrospinal fluid column between the tumor and the entrance of the internal auditory canal. The percentage of tumor diameter reduction ranged from 20% to 40%. CONCLUSIONS: Some MRI features may demonstrate a spontaneous involution of VS and may be closely followed in asymptomatic or oligosymptomatic patients.

ABSTRACT: Cervical spondylotic myelopathy (CSM) is a common disease with an increased anticipated burden to health systems worldwide. Methods to predict outcomes in these patients are needed so physicians can provide more effective care. Fractional anisotropy (FA) analysis is a promising technique used to quantify how preserved the diffusion is in neural pathways. A systematic review and meta-analysis were performed using the PRISMA guidelines. Full articles available online were searched for correlation coefficients between FA values and mJOA scores. Average FA values, preoperative mJOA, and postoperative mJOA scores were gathered to perform a correlation analysis. A total of 5 articles presented correlations between FA and mJOA change and were included in the correlation meta-analysis. Correlation coefficients varied from -0.42 and 0.55. The number of patients in each study varied from 15 to 95. The Random effects model resulted in a non-significant correlation coefficient of 0.1315 (95% CI: -0.2575 to 0.4839; p= 0.5124). Spearman's correlation analysis was significant for preoperative vs postoperative mJOA (r = 0.79, p = 0.02), while preoperative FA did not correlate significantly with preoperative or postoperative mJOA. At this point, the data available in the literature is insufficient to determine a real correlation between FA and mJOA scores. More studies are necessary for a better understanding of this matter. Level of Evidence III; Study Review.
RESUMO: A mielopatia espondilótica cervical (CSM, pelas suas siglas em inglês) é uma doença comum com elevados gastos para os sistemas de saúde em todo o mundo. Métodos para prever resultados nesses pacientes são necessários para que a atenção médica seja mais eficaz. A análise de anisotropia fracionada (FA) é uma técnica promissora usada para quantificar a preservação da difusão nas vias neurais. Uma revisão sistemática e meta-análise foi realizada usando as diretrizes PRISMA. Artigos completos disponíveis online foram avaliados em busca de coeficientes de correlação entre valores de FA e escores de mJOA. Valores médios de FA, escores de mJOA pré-operatórios e pós-operatórios foram coletados para realizar uma análise de correlação. Um total de 5 artigos apresentaram correlações entre alteração de FA e mJOA e foram incluídos na meta-análise de correlação. Os coeficientes de correlação variaram entre -0,42 e 0,55. O número de pacientes em cada estudo variou de 15 a 95. O modelo de efeitos aleatórios resultou em um coeficiente de correlação não significativo de 0,1315 (95% CI: -0,2575 a 0,4839; p= 0,5124). A análise de correlação de Spearman foi significativa para mJOA pré-operatório vs. pós-operatório (r = 0,79, p = 0,02), enquanto a FA pré-operatório não apresentou correlação significativa com o mJOA pré-operatório ou pós-operatório. Os dados disponíveis na literatura neste momento são insuficientes para determinar uma correlação real entre os escores FA e mJOA. Mais estudos são necessários para uma melhor compreensão deste assunto. Nível de Evidência III; Revisão de Estudos.

BACKGROUND: Hemangioblastomas account for about 1%-3% of all central nervous system tumors. They are usually associated with the Von Hippel-Lindau syndrome and typically occur in the posterior fossa, or throughout the spinal neuraxis. Here, we report the unusual case of a sporadic cauda equina hemangioblastoma. CASE DESCRIPTION: A 28-year-old Caucasian female patient presented with progressive low back pain of 2 months duration. The magnetic resonance (MR) revealed a heterogeneous intradural and extramedullary lesion at the L2 level; with intravenous contrast, there were vascular flow voids and surrounding vasogenic edema (i.e., measuring 4.1 cm × 3.5 cm). The patient underwent an L2 right hemilaminectomy under intraoperative neurophysiological monitoring. She was discharged the 4th postoperative day, neurologically intact. Literature describes 21 previous reports of sporadic isolated spinal hemangioblastomas. CONCLUSION: Although rare, sporadic, and isolated hemangioblastomas of the cauda equina should be included among the differential diagnoses of intradural spinal lesions, particularly when enhanced MR studies document serpentine flow voids.
RESUMO
INTRODUCTION: Chordoma is a malignant tumor that usually involves the axial skeleton. Intradural chordomas are even rarer and 37 cases have been reported to the best of our knowledge. We present a case of a patient with an atypical metastatic diffuse intradural spinal involvement. CASE DESCRIPTION: We present a 33-year-old woman previously submitted to five brain surgeries to treat a posterior fossa intradural chordoma since December 2012. Currently, she presented almost with right and left hemiplegia (grade 2 bilaterally) and also left oculomotor, adbucent and facial nerve paresis. We performed neuroaxis magnetic resonance MR which disclosed stability of posterior fossa tumor which was previously irradiated. However, there were new intradural lesions at the level of C3, T11/T12 and L4/L5/S1 vertebrae. DISCUSSION: With the advent of contemponaeous surgery, radiotherapy options and even available chemotherapy to treat Chordomas (Imatinib), patients may experience enlarged survival and thus face complications such as drop metastases along neuroaxis. Our case illustrates a late (6â¯years) follow-up presentation of an initial posterior fossa intradural chordoma. It suggests that whole neuraxis involvement may be the final presentation of all patients harbouring chordomas and surviving after adequate initial treatment.

METHODS: Thirty cases, previously treated according to the new algorithm, were presented to four spine surgeons who were questioned about their personal suggestion for treatment, and the treatment suggested according to the application of the algorithm. After four weeks, the same questions were asked again to evaluate reliability (intra- and inter-observer) using the Kappa index. RESULTS: The reliability of the treatment suggested by applying the algorithm was superior to the reliability of the surgeons' personal suggestion for treatment. When applying the upper cervical spine injury treatment algorithm, an agreement with the treatment actually performed was obtained in more than 89% of the cases. CONCLUSION: The system is safe and reliable for treating traumatic upper cervical spine injuries. The algorithm can be used to help surgeons in the decision between conservative versus surgical treatment of these injuries.

INTRODUCTION: Chiari malformation type I (CM) is the main congenital malformation disease of the craniovertebral junction. The ideal surgical treatment is still controversial. Invasive procedures inside the cerebrospinal fluid (CSF) space and associated with dural repair are considered the gold standard; however, less invasive surgery with isolated bone decompression without dural opening may be possible in selected patients. Our study evaluates the efficacy of intraoperative CSF flow measurement with ultrasonography (USG) as a determining parameter in the selection of these patients. METHODS: We analyzed prospectively 49 patients with CM operated on at the Hospital das Clínicas, College of Medicine, University of São Paulo. Patients underwent decompressive surgery with or without opening of the dura mater after intraoperative USG measuring flow rate. A value of 3 cm/second was considered a cutoff. Quality of life before and after surgery and the improvement of neck pain and headache were evaluated. RESULTS: Among 49 patients enrolled, 36 patients (73%) had CSF flow >3 cm/second and did not undergo duraplasty. In 13 patients (27%) with initial flow <3 cm/second, dural opening was performed together with duraplasty. All patients improved when preoperative and postoperative scores were compared, and all clinical parameters evaluated did not differ between both surgical groups. Patients submitted to bone decompression alone had a lower complication rate. CONCLUSIONS: Intraoperative USG with measurement of CSF allows the proper selection of patients with CM for less invasive surgery with bone decompression without duraplasty.

UNLABELLED: Paraclinoid aneurysms are lesions located adjacent to the clinoid and ophthalmic segments of the internal carotid artery. In recent years, flow diverter stents have been introduced as a better endovascular technique for treatment of these aneurysms. METHOD: From 2009 to 2014, a total of 43 paraclinoid aneurysms in 43 patients were surgically clipped. We retrospectively reviewed the records of these patients to analyze clinical outcomes. RESULTS: Twenty-six aneurysms (60.5%) were ophthalmic artery aneurysms, while 17 were superior hypophyseal artery aneurysms (39.5%). The extradural approach to the clinoid process was used to clip these aneurysms. One hundred percent of aneurysms were clipped (complete exclusion in 100% on follow-up angiography). The length of follow-up ranged from 1 to 60 months (mean, 29.82 months). CONCLUSION: Surgical clipping continues to be a good option for the treatment of paraclinoid aneurysms.

Spinal cord epidural metastasis (SEM) is a common complication of systemic cancer. Predicting these patient's survival is a key factor to select the proper treatment modality, but the three most used score scales to predict their survival (Tokuhashi revised score, Tomita score and Bauer modified score) were designed in single institutions and their reliability to predict correctly the patient's survival were first tested only in those specific populations. This prognostication issue is addressed in this article, evaluating retrospectively the survival of 17 patients with SEM from a Brazilian general hospital with these score scales. Our results show that the actual survival of those patients were worse than the predicted of all three score scales, suggesting that differences between the different populations might have affected their reliability and alert that their usage as a major factor to select the most appropriate treatment have to be done with caution.

Indocyanine green (ICG) video angiography has been used for several medical indications in the last decades. It allows a real time evaluation of vascular structures during the surgery. This study describes the surgical results of a senior vascular neurosurgeon. We retrospectively searched our database for all aneurysm cases treated with the aid of intraoperative ICG from 2009 to 2014. A total of 61 aneurysms in 56 patients were surgically clipped using intraoperative ICG. Clip reposition after ICG happened in 2 patients (3.2%). Generally, highly variable clip adjustment rates of 2%-38% following ICG have been reported since the introduction of this imaging technique. The application of ICG in vascular neurosurgery is still an emerging challenge. It is an adjunctive strategy which facilitates aneurismal evaluation and treatment in experienced hands. Nevertheless, a qualified vascular neurosurgeon is still the most important component of a high quality work.

BACKGROUND: Lumbar discectomy is still one of the most common spinal surgeries performed today. Nevertheless, there are few publications considering severe complications. CASE DESCRIPTION: We report a case with severe complication, without any previous report, a brain empyema after cerebrospinal fluid leak with good outcome afterword. A 45 years old man, returned six days after surgery, presenting cerebrospinal fluid leak, which after clinical and laboratory deterioration was reoperated. In the 14th postoperative facing worsening level of consciousness was diagnosed empyema in cerebellopontine angle and hydrocephalus underwent emergency surgery. Evolved with hemiplegia in the first postoperative attributed to vasculitis, completely recovered after 5 days. CONCLUSIONS: Although infrequent, lumbar discectomy is subject to severe complications, which as the case presented, can be dramatic. In surgeries must be careful to avoid cerebrospinal fluid leak e infectious complications.
RESUMO
Gunshot wounds (GSW) to the cervical spine leading to instability are rare. Also, the presence of vital vascular and neurological structures in the surround area lead to death or severe disability in the vast majority of cases. In this brief report, we present a rare case of C1 fracture due to GSW leading to instability of the atlanto-occipital joint in a neurologically intact patient.
RESUMO
Subarachnoid hemorrhage following intracranial aneurysmal rupture is a major cause of morbidity and mortality. Several factors may affect the probability of rupture, such as tobacco and alcohol use; size, shape, and location of the aneurysm; presence of intraluminal thrombus; and even the sex of the patient. However, few data correlate such findings with the timing of aneurysmal rupture. The authors report 2 cases of middle-age women with headache and MRI findings of incidental aneurysms. Magnetic resonance imaging showed evidence of surrounding parenchymal edema, and in one case there was a clear increase in edema during follow-up, suggesting a progressive inflammatory process that culminated with rupture. These findings raise the possibility that bleb formation and an enlargement of a cerebral aneurysm might be associated with an inflammatory reaction of the aneurysm wall resulting in perianeurysmal edema and subsequent aneurysmal rupture. There may be a temporal link between higher degree of edema and higher risk for rupture, including risk for immediate rupture.

RESUMO Avaliamos a reprodutibilidade e segurança do algoritmo Upper Cervical Spine Injuries Treatment Algorithm (UCITA) recém proposto para a escolha do tratamento das lesões traumáticas da junção crânio-cervical. Métodos Trinta casos previamente tratados de acordo com o algoritmo foram apresentados a quatro cirurgiões de coluna, sendo questionada a conduta pessoal dos mesmos e a conduta segundo a aplicação do algoritmo. Após 4 semanas, foram refeitas as mesmas perguntas para avaliar a reprodutibilidade (intra e interobservador) do algoritmo, através do índice estatístico “Kappa”. Resultados A reprodutibilidade da conduta com o uso do algoritmo foi superior a reprodutibilidade da conduta pessoal dos cirurgiões. Com o uso do UCITA, a concordância do tratamento realmente efetivado foi encontrada em mais de 89% dos casos. Conclusão O uso do UCITA foi seguro e reprodutível, podendo ser usado como ferramenta auxiliar na tomada de decisão entre tratamento cirúrgico versus conservador dos traumatismos da junção crâniocervical.

RESUMO Metástases vertebrais são uma complicação comum em pacientes com câncer sistêmico. Avaliar o prognóstico e a sobrevida desses pacientes é um fator de grande importância para escolher o tratamento mais adequado, porém as três escalas mais usadas atualmente para prever a sobrevida deles (Tokuhashi revisada, Tomita e Bauer modificada) foram desenhadas em instituições isoladas, e sua habilidade em estimar corretamente a sobrevida desses pacientes foram testadas primeiramente apenas nessas populações específicas. Essa questão de estimar o prognóstico é abordada nesse artigo, analisando retrospectivamente a sobrevida de 17 pacientes com metástase vertebral provenientes de um hospital geral no Brasil com essas escalas. Nossos resultados apontam que a sobrevida real desses pacientes foi menor que a prevista pelas três escalas, sugerindo que as diferenças entres as diferentes populações podem ter afetado a aplicabilidade delas. Assim, alertamos que o uso dessas escalas em populações diferentes das estudadas originalmente deve ser feito com cuidado.

BACKGROUND: Ventricular drainage has played an important role in the management of traumatic brain-injured patients. The aim of the present study was describe outcomes in a series of 57 patients with diffuse brain swelling underwent to intracranial pressure (ICP) monitoring. METHOD: Fifty-eight patients with diffuse posttraumatic brain swelling, were evaluated prospectively. The Glasgow Coma Scale (GCS) scores of patients varied from 4 to 12. Patients groups divided according to GCS and age. Patient neurological assessment was classified as favorable, unfavorable, and death. RESULTS: Mechanisms of injury were vehicle accidents in 72.4% and falls in 15.6%. 54% of patients had GCS scores between 6 and 8. There were no statistical differences, regarding outcome, between groups separated by age. In the adults group (n=47), 44.7% evolved favorably. CONCLUSION: Our results indicate a poor prognosis in patients with brain swelling. We believe that continuous ventricular CSF drainage with ICP monitoring is a simple method as an adjunct in the management of these patients.

Objective. Subdural hygroma is reported to occur in 5%-20% of all patients with closed head trauma, the treatment is controversial and in symptomatic cases surgical drainage is need. We report on a new case with remote acute epidural hematoma (AEH) after subdural hygroma drainage. Case Presentation. A 38-year-old man suffered blunt head trauma and had diffuse axonal injury grade III in CT scan. A CT scan that was late performed showed an increasing subdural fluid collection with mild mass effect and some effacement of the left lateral ventricle. We perform a trepanation with drainage of a hypertensive subdural collection with citrine aspect. Postoperative tomography demonstrated a large left AEH. Craniotomy and evacuation of the hematoma were performed. Conclusion. The mechanism of remote postoperative AEH formation is unclear. Complete reliance on neurologic monitoring, trust in an early CT scan, and a relative complacency after an apparently successful initial surgery for hygroma drainage may delay the diagnosis of this postoperative AEH.
