Childs Nerv Syst 2024; 40:1079-1089. [PMID: 38321255 DOI: 10.1007/s00381-024-06311-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 01/29/2024] [Indexed: 02/08/2024]
Abstract
PURPOSE Intramedullary spinal cord tumors are an uncommon pathology in adults and children. Most descriptive studies of intramedullary spinal cord tumors have not focused on a possible association with future brain lesions. To the best of our knowledge, few reports describe this potential relationship. This is one of the most extensive case series of secondary brain lesions of intramedullary spinal cord tumors in the pediatric population. METHODS Retrospective chart review was performed on pediatric patients (21 years old and younger) who underwent resection of an intramedullary spinal cord tumor at two tertiary care hospitals from 2001 to 2020. Patients previously treated or diagnosed with spinal cord tumor, and subsequent development of intracranial manifestation of the same or different tumor, were included. Data regarding epidemiology, surgical intervention, and clinical and follow-up course were gathered. Data analysis was performed according to a standardized clinical protocol with a literature review. RESULT More than 500 patients underwent intradural spinal tumor resection surgeries at participating hospitals from 2001 to 2020. After excluding adult patients (older than 21 years old) and those with extramedullary lesions, 103 pediatric patients were identified who underwent resection of an intramedullary spinal cord tumor. Four underwent resection of an intermedullary tumor and later in their follow-up course developed a secondary intracranial neoplasm. In every case, the secondary neoplasm had the same pathology as the intramedullary tumor. Three of the patients had tumors at the cervico-thoracic junction, and one patient had a high cervical tumor. These patients had a negative primary workup for any metastatic disease at the time of the presentation or diagnosis. Complete and near complete resection was performed in three patients and subtotal in one patient. CONCLUSION Secondary brain tumors disseminated after initial spinal cord tumor are extremely rare. This study aims to allow specialists to better understand these pathologies and treat these rare tumors with more certainty and better expectations of unusual associated lesions and conditions.

The efficacy of preoperative diffusion tensor tractography on surgical planning and outcomes in patients with intramedullary spinal tumor. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:4321-4327. [PMID: 37530950 DOI: 10.1007/s00586-023-07872-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 04/14/2023] [Accepted: 07/23/2023] [Indexed: 08/03/2023]
Abstract
PURPOSE The aim of this study was to investigate the efficacy of diffusion tensor tractography (DTT) of spinal cord on surgical planning and postoperative neurological outcomes in patients with spinal intramedullary tumors. METHODS The study was conducted retrospectively from the radiological and clinical data of our hospital database. Patients with intramedullary spinal cord tumors who underwent diffusion tensor imaging for spinal cord lesions were selected between 2019 and 2022. Demographic characteristics and intraoperative neurophysiological monitoring data were evaluated. The McCormick scale was used to grade the pre- and postoperative neurological status of the patients. The tumoral lesions were categorized into 3 types according to the fiber course on DTT. RESULTS Eleven patients were found to have radiological findings that were compatible with intramedullary tumor; eight (72.7%) of them ultimately underwent surgery following being approved as surgical candidates in the spinal diffusion tensor imaging studies. Six cases had Type 1, one case had Type 2, and 4 cases had Type 3 tumors according to the fiber course. All Type 1 tumors were classified as resectable and all of them were gross totally resected. Type 2 lesion that was rated as resectable by DTI was subtotally resected. Type 3 lesions were followed without surgery except the one with tumoral progression and neurological deficit. The postoperative neurological outcomes were compatible with intraoperative neurophysiological monitoring results. CONCLUSION Diffusion tensor imaging and tractography may be beneficial regarding the selection of patients suitable for surgery and in the subsequent surgical planning.

Abstract
Background: Intradural extramedullary cavernous hemangiomas of the spine are rare, benign lesions with only 40 published cases to date. Case Description: The authors report a rare case of a histologically diagnosed intradural extramedullary cavernous hemangioma of the spine involving the cervicothoracic junction and causing sudden gait disturbances and urinary retention in a 24-year-old male. Gross total tumor removal allowed complete spinal decompression and sensible improvement of the clinical condition with no evidence of tumor relapse at 12-month follow-up examination. Conclusion: More frequently found in the lower thoracic and lumbar spine, these tumors often cause subtle clinical manifestations including sensory and motor dysfunction secondary to nerve root compression; nonetheless, occasional cases of rapidly progressive worsening of the neurological condition with evidence of myelopathy and autonomic dysfunction have been described. In such cases, urgent surgical resection is crucial since the degree of neurological impairment and the time spanned from the onset of the symptoms are paramount for a good recovery.

Frailty Status Is a More Robust Predictor Than Age of Spinal Tumor Surgery Outcomes: A NSQIP Analysis of 4,662 Patients. Neurospine 2022; 19:53-62. [PMID: 35130424 PMCID: PMC8987561 DOI: 10.14245/ns.2142770.385] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 11/22/2021] [Indexed: 11/19/2022] Open
Abstract
Objective The present study aimed to evaluate the effect of baseline frailty status (as measured by modified frailty index-5 [mFI-5]) versus age on postoperative outcomes of patients undergoing surgery for spinal tumors using data from a large national registry.
Methods The National Surgical Quality Improvement Program database was used to collect spinal tumor resection patients’ data from 2015 to 2019 (n = 4,662). Univariate and multivariate analyses for age and mFI-5 were performed for the following outcomes: 30-day mortality, major complications, unplanned reoperation, unplanned readmission, hospital length of stay (LOS), and discharge to a nonhome destination. Receiver operating characteristic (ROC) curve analysis was used to evaluate the discriminative performance of age versus mFI-5.
Results Both univariate and multivariate analyses demonstrated that mFI-5 was a more robust predictor of worse postoperative outcomes as compared to age. Furthermore, based on categorical analysis of frailty tiers, increasing frailty was significantly associated with increased risk of adverse outcomes. ‘Severely frail’ patients were found to have the highest risk, with odds ratio 16.4 (95% confidence interval [CI],11.21–35.44) for 30-day mortality, 3.02 (95% CI, 1.97–4.56) for major complications, and 2.94 (95% CI, 2.32–4.21) for LOS. In ROC curve analysis, mFI-5 score (area under the curve [AUC] = 0.743) achieved superior discrimination compared to age (AUC = 0.594) for mortality.
Conclusion Increasing frailty, as measured by mFI-5, is a more robust predictor as compared to age, for poor postoperative outcomes in spinal tumor surgery patients. The mFI-5 may be clinically used for preoperative risk stratification of spinal tumor patients.

Diffusion tensor imaging in unclear intramedullary tumor-suspected lesions allows separating tumors from inflammation. Spinal Cord 2021; 60:655-663. [PMID: 34966172 PMCID: PMC9287173 DOI: 10.1038/s41393-021-00741-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 12/14/2021] [Accepted: 12/16/2021] [Indexed: 11/08/2022]
Abstract
DESIGN Prospective diagnostic study. OBJECTIVES Primary imaging-based diagnosis of spinal cord tumor-suspected lesions is often challenging. The identification of the definite entity is crucial for dedicated treatment and therefore reduction of morbidity. The aim of this trial was to investigate specific quantitative signal patterns to differentiate unclear intramedullary tumor-suspected lesions based on diffusion tensor imaging (DTI). SETTING Medical Center - University of Freiburg, Germany. METHODS Forty patients with an unclear tumor-suspected lesion of the spinal cord prospectively underwent DTI. Primary diagnosis was determined by histological or clinical work-up or remained indeterminate with follow-up. DTI metrics (FA/ADC) were evaluated at the central lesion area, lesion margin, edema, and normal spinal cord and compared between different diagnostic groups (ependymomas, other spinal cord tumors, inflammations). RESULTS Mean DTI metrics for all spinal cord tumors (n = 18) showed significantly reduced FA and increased ADC values compared to inflammatory lesions (n = 8) at the lesion margin (p < 0.001, p = 0.001) and reduced FA at the central lesion area (p < 0.001). There were no significant differences comparing the neoplastic subgroups of ependymomas (n = 10) and other spinal cord tumors (n = 8), but remaining differences for both compared to the inflammation subgroup. We found significant higher ADC (p = 0.040) and a trend to decreased FA (p = 0.081) for ependymomas compared to inflammations at the edema. CONCLUSION Even if distinct differentiation of ependymomas from other spinal cord neoplasms was not possible based on quantitative DTI metrics, FA and ADC were feasible to separate inflammatory lesions. This may avoid unnecessary surgery in patients with unclear intramedullary tumor-suspected lesions.

Abstract
OBJECTIVE Histologic types and grades are critical in the diagnosis and treatment of spinal tumors. Intraoperative frozen section is a fast and easy method in confirming pathologic diagnosis during the operation. This study was undertaken to reveal the accuracy of intraoperative frozen section biopsy in order to make proper treatment plans. METHODS This retrospective study concerned patients who underwent spinal tumor surgeries from 1 January, 2012 to 31 December, 2016. Frozen section biopsy and permanent biopsy were compared, and cases that had differences were counted. RESULTS Thirty-seven cases out of 324 patients had discrepancies (11.4%). In discrepant cases 11 cases were ependymoma (29.7%) and 6 cases were schwannoma (16.2%). Among 34 patients who were finally diagnosed with an ependymoma, 11 cases had discrepancies, which was the highest mismatch rate among tumor final pathologic types. By frozen biopsy, astrocytoma (n = 5) and ependymoma (n = 5) turned out to be the most discrepant pathologic types and 16 frozen section biopsy cases were "null." Frozen biopsy astrocytoma (n = 5) mostly turned out to be ependymoma in 4 cases. CONCLUSIONS Pathologic findings from frozen biopsy for spinal cord tumors could not be corresponded to final diagnosis, especially when the results of frozen biopsy were ependymoma or astrocytoma. Therefore careful decision making for treatment plans is required.

Abstract
BACKGROUND Intramedullary capillary hemangiomas are rare lesions with only 14 cases reported so far and are found in middle-aged persons. Until now only a single case has been reported in the pediatric population. Ours was the second pediatric case and the youngest of all to be diagnosed with an intramedullary capillary hemangioma. CASE DESCRIPTION We are reporting the case of a 2-month male child who presented with features of hydrocephalus and spastic paraparesis. On magnetic resonance imaging he had features suggestive of a D10-11 intradural extramedullary lesion and hydrocephalus. We did a ventriculoperitoneal shunt followed by excision of the lesion in the same sitting. Intraoperatively it was found to be an intramedullary lesion, and histopathologic examination showed features suggestive of capillary hemangioma. Postoperatively he recovered well and there is no recurrence 18 months after surgery. CONCLUSIONS Intramedullary capillary hemangiomas are extremely rare lesions in infants but should be kept in mind while treating any patient with the spinal lesion. Further reporting of similar cases will help in understanding the natural history, pathogenesis, and management.

Abstract
The article addresses the problem of intramedullary tumors (IMTs) combined with hydrocephalus (HC). PURPOSE The study purpose was to explore, based on large clinical material, the occurrence of hydrocephalus combined with intramedullary tumors, possible pathogenetic mechanisms of its development, effect of tumor resection on the course of hydrocephalus, and need and timing of shunting surgery. MATERIAL AND METHODS We present and analyze the data of the largest individual series of patients of all age groups operated on for IMTs of the spinal cord: 541 patients; 586 operations; age from 2 months to 72 years. RESULTS AND CONCLUSION Our findings confirm a potential pathogenetic relationship between IMT and HC. The overall occurrence rate of HC in IMT patients was 6.3%. In patients with benign tumors (WHO Grade 1-2; 449 patients), HC developed in 25 (5.6%) cases; in patients with malignant tumors (WHO Grade 3-4; 84 patients), HC developed in 7 (8.3%) cases. A statistically significant prevalence of cervico-medullary tumors was found in HC patients: 19 (59.4%) cases. According to our data, dissemination of the tumor process is a potential factor of HC development.

Abstract
Intramedullary spinal lesions present a wide differential diagnosis including infectious, inflammatory, traumatic, ischemic, benign, or malignant neoplastic etiologies. Using knowledge of anatomy and physiology within the spinal cord, many similar appearing entities can be parsed into a prioritized differential. The purpose of this article is to review anatomy and pathophysiology of the spinal cord, with subsequent discussion of how this knowledge can be used to differentiate several similar appearing intramedullary pathologic processes. Discussion includes the pathophysiology, imaging findings, and clinical pearls of several intramural lesions including infarct, demyelinating lesions, traumatic injury, neoplasm, vascular malformation, and metabolic processes such as subacute combined degeneration.

Abstract
OBJECTIVES Capillary hemangiomas are benign vascular tumors. They are commonly founded in the vertebral bodies but very seldom in the spinal cord. The most common symptom at onset is long-lasting axial pain without neurologic deficit. In rare cases, the onset may be acute with neurological deficit due to an intratumoral hemorrhage. PATIENT AND METHODS We report a case of a 58-year-old male with a history of 15 days upper back pain triggered by a mild traumatism that evolves acutely to paraplegia and urinary and fecal retention. An urgent MR showed an intradural lesion with signs of intratumoral haemorrhage. RESULTS Urgent surgical intervention was performed and the anatomopathological results were capillary hemangioma. The symptoms of the patient improved after the surgery. CONCLUSIONS Intradural capillary hemangioma with acute intratumoral hemorrhage is a rare pathology, but it must be kept in mind because early diagnosis and treatment are key to achieve a good outcome. As far as we know, this is the first case reported of an intradural-extramedular capillary hemangioma that presents sudden neurologic deficit due to intratumoral bleeding.

Abstract
BACKGROUND AND PURPOSE Primary MRI diagnosis of spinal intramedullary tumor-suspected lesions can be challenging and often requires spinal biopsy or resection with a substantial risk of neurological deficits. We evaluated whether Diffusion Tensor Imaging (DTI) tractography can facilitate the differential diagnosis. MATERIALS AND METHODS Twenty-five consecutive patients with an intramedullary tumor-suspected lesion considered for spinal surgery were studied with a Diffusion-weighted multi-shot read out segmented EPI sequence (RESOLVE). White matter tracts ("streamlines") were calculated using the FACT algorithm and visually co-registered to a T2-weighted 3D sequence. The fused images were assessed concerning spinal streamline appearance as normal, displaced or terminated. Definite diagnosis was verified by histological analysis or further clinical work-up. RESULTS All patients with normal appearing streamlines (n=6) showed an acute inflammatory demyelinating pathology in the further clinical work-up. In 10 patients streamline displacing lesions were found from which 5 patients underwent a surgical treatment with histologically confirmed low-grade tumors like ependymomas and pilocytic astrocytomas. In nine patients streamlines were terminated, from which 6 patients received a histology proven diagnoses with a more heterogenous spectrum (3 cases of high grade tumor, 1 case of low grade tumor with intralesional hemorrhage and 2 cases with gliosis but no tumor cells). CONCLUSION Using multi-shot DTI spinal tractography acute inflammatory lesions can be differentiated from other tumorous intramedullary lesions. The entity diagnosis of spinal tumors seems to be more challenging, primarily due to the variety of factors like invasivity, expansion or intralesional hemorrhage.

Abstract
Context: In the absence of a community-based study on the spinal tumors in the Valley, medical records of the only Regional Neurosurgical Center are available. Aim: The aim of this study is to establish a hospital-based regional epidemiology of spinal tumors in the Valley since the data are derived from a single institution. Materials and Methods: A retrospective analysis of 531 malignant and nonmalignant tumors of spinal cord, its coverings and vertebrae, which were managed in a Regional Neurosurgical Center under a standard and uniform medical-protocol over 30-year period from 1983 to 2014. Results: The hospital-based incidence for all spinal tumors was 0.24/100,000 persons per year. The malignant spinal cord and vertebral tumors comprised 32.58% (173/531) of all tumors, and benign spinal cord and vertebral tumors comprised 67.42% (358/531). The extradural–intradural tumors such as metastatic lesions and primary malignant vertebral tumors were on rise with 16.38% (87/531) cases. The children below 18 years were 5.46% (29/531), of which 55.17% (16/29) were below 9 years. The most common primary bone malignancy was multiple myeloma (54.54% =12/22). Histopathologically, the most common metastatic deposit in the spinal canal was non-Hodgkin's lymphoma (24.61% =16/65). A mortality of 3.20% (17/531) was noted. Recurrences were noted in 4.90% (26/531), and adjuvant therapies were given to 16.38% (87/531) patients. Conclusion: The malignant spinal cord and vertebral tumors, especially metastatic deposits, are on rise in elderly population. The surgical outcome, in terms of recovery and spinal stability, of benign tumors, is comparatively better than malignant ones. The study reveals a low regional incidence (hospital-based) of spinal tumors.

Abstract
We evaluate our preliminary experience using the Cyberknife® Radiosurgery System in treating benign spinal tumors. A retrospective review of 16 consecutively treated patients, comprising 19 benign spinal tumors, was performed. Histologic types included neurofibroma [11], chordoma [4], hemangioma [2], and meningioma [2]. Three patients had Neurofibromatosis Type 1 (NF1). Only one tumor, recurrent chordoma, had been previously irradiated, and as such not considered in the local failure analysis. Local failure, for the remaining 18 tumors, was based clinically on symptom progression and/or tumor enlargement based on imaging. Indications for spine stereotactic body radiotherapy (SBRT) consisted of either adjuvant to subtotal resection (5/19), primary treatment alone (12/19), boost following external beam radiotherapy (1/19), and salvage following previous radiation (1/19). Median tumor follow-up is 25 months (2–37), and one patient (with NF1) died at 12 months from a stroke. The median total dose, number of fractions, and prescription isodose was 21 Gy (10–30 Gy), 3 fx (1–5 fx), 80% (42–87%). The median tumor volume was 7.6 cc (0.2–274.1 cc). The median V100 (volume V receiving 100% of the prescribed dose) and maximum tumor dose was 95% (77–100%) and 26.7 Gy (15.4–59.7 Gy), respectively. Three tumors progressed at 2, 4, and 36 months post-SR (n=18). Two tumors were neurofibromas (both in NF1 patients), and the third was an intramedullary hemangioblastoma. Based on imaging, two tumors had MRI documented progression, three had regressed, and 13 were unchanged (n=18). With short follow-up, local control following Cyberknife spine SBRT for benign spinal tumors appear acceptable.

Abstract
UNLABELLED Intramedullary spinal cord tumors (IMSCTs) are a rare pathology. They can be found at any age. Our experience with more than 507 surgeries for IMSCTs revealed some differences between pediatric and adult IMSCTs. AIM We used a large surgical series to conduct comparative analysis of the main epidemiological characteristics of intramedullary tumors in children and adults and to identify possible differences. MATERIAL AND METHODS Prospectively collected data from 224 pediatric and 242 adult patients operated by one surgeon (YK) for last 12 years were analyzed. RESULTS Pediatric IMSCTs are more extensive and children undergo treatment in worse clinical condition than adults. There are age-related differences in the tumor localization. The astrocytoma/ependymoma ratio was 83/17 in children and 21/79 in adults. CONCLUSION We confirmed differences in IMSCTs in different age groups. Late diagnosis is a problem in the pediatric subgroup of IMSCT patients.

Abstract
Intramedullary, intradural/extramedullary, and extradural spine tumors comprise a wide range of neoplasms with an even wider range of clinical symptoms and prognostic features. Magnetic resonance imaging (MRI), commonly used to evaluate the spine in patients presenting with pain, can further characterize lesions that may be encountered on other imaging studies, such as bone scintigraphy or computed tomography (CT). The advantage of the MRI is its multiplane capabilities, superior contrast agent resolution, and flexible protocols that play an important role in assessing tumor location, extent in directing biopsy, in planning proper therapy, and in evaluating therapeutic results. A multimodality approach can be used to fully characterize the lesion and the combination of information obtained from the different modalities usually narrows the diagnostic possibilities significantly. The diagnosis of spinal tumors is based on patient age, topographic features of the tumor, and lesion pattern, as seen at CT and MRI. The shift to high-end imaging incorporating diffusion-weighted imaging, diffusion tensor imaging, magnetic resonance spectroscopy, whole-body short tau inversion recovery, positron emission tomography, intraoperative and high-field MRI as part of the mainstream clinical imaging protocol has provided neurologists, neuro-oncologists, and neurosurgeons a window of opportunity to assess the biologic behavior of spine neoplasms. This chapter reviews neuroimaging of spine tumors, primary and secondary, discussing routine and newer modalities that can reduce the significant morbidity associated with these neoplasms.

Abstract
Background: Pediatric intramedullary spinal cord lesions are not only rare but also different from adults in a number of aspects. We aimed to study the incidence and the frequencies of various pediatric intramedullary mass lesions, their outcome to treatment and the factors determining their outcome of treatment. Materials and Methods: Thirty-one consecutive children (aged 1–18 years, mean 11.1 years, male: female = 1.8:1) with pathologically proven intramedullary spinal cord lesions treated at our center were studied. Clinico-radiological, histopathological, operative, and outcome data were reviewed retrospectively. The functional status was assessed using the modified McCormick grading system. Results: Gross total tumor excision was performed in 19 patients (61.3%), subtotal in 9 patients (29%), partial excision was performed in 2 (6.5%) patient, and only biopsy was performed in 1 patient (6.5%). There was one peroperative death, 2 patients died at follow-up. Complications included wound related complications (n = 4), transient deterioration in the motor power, and respiratory complication requiring a tracheostomy. Six patients showed recurrence at a mean follow-up of 16.4 months. Developmental tumors, high-grade ependymomas, and incompletely excised grade 2 ependymomas showed a tendency to recur. Conclusions: Children constituted nearly 1/5th (17.4%) of intramedullary spinal cord tumors. Astrocytomas and ependymomas taken together constituted the most common intramedullary spinal lesions in children; however, developmental tumors predominated in the first decade. Children usually presented in good functional grades preoperatively and maintained good grades after surgery. Functional outcome was dependent on the preoperative neurological status and histopathology of the lesions.

Abstract
OBJECT
Because of the limited data available regarding the associations between risk factors and the effect of hospital case volume on outcomes after resection of intradural spine tumors, the authors attempted to identify these associations by using a large population-based database.
METHODS
Using the National Inpatient Sample database, the authors performed a retrospective cohort study that involved patients who underwent surgery for an intradural spinal tumor between 2002 and 2011. Using national estimates, they identified associations of patient demographics, medical comorbidities, and hospital characteristics with inpatient postoperative outcomes. In addition, the effect of hospital volume on unfavorable outcomes was investigated. Hospitals that performed fewer than 14 resections in adult patients with an intradural spine tumor between 2002 and 2011 were labeled as low-volume centers, whereas those that performed 14 or more operations in that period were classified as high-volume centers (HVCs). These cutoffs were based on the median number of resections performed by hospitals registered in the National Inpatient Sample during the study period.
RESULTS
Overall, 18,297 patients across 774 hospitals in the United States underwent surgery for an intradural spine tumor. The mean age of the cohort was 56.53 ± 16.28 years, and 63% were female. The inpatient postoperative risks included mortality (0.3%), discharge to rehabilitation (28.8%), prolonged length of stay (> 75th percentile) (20.0%), high-end hospital charges (> 75th percentile) (24.9%), wound complications (1.2%), cardiac complications (0.6%), deep vein thrombosis (1.4%), pulmonary embolism (2.1%), and neurological complications, including durai tears (2.4%). Undergoing surgery at an HVC was significantly associated with a decreased chance of inpatient mortality (OR 0.39; 95% CI 0.16−0.98), unfavorable discharge (OR 0.86; 95% CI 0.76−0.98), prolonged length of stay (OR 0.69; 95% CI 0.62−0.77), high-end hospital charges (OR 0.67; 95% CI 0.60−0.74), neurological complications (OR 0.34; 95% CI 0.26−0.44), deep vein thrombosis (OR 0.65; 95% CI 0.45−0.94), wound complications (OR 0.59; 95% CI 0.41−0.86), and gastrointestinal complications (OR 0.65; 95% CI 0.46−0.92).
CONCLUSIONS
The results of this study provide individualized estimates of the risks of postoperative complications based on patient demographics and comorbidities and hospital characteristics and shows a decreased risk for most unfavorable outcomes for those who underwent surgery at an HVC. These findings could be used as a tool for risk stratification, directing presurgical evaluation, assisting with surgical decision making, and strengthening referral systems for complex cases.

Abstract
CONTEXT Hemangioblastomas of the spinal cord are uncommon vascular tumors. Patients commonly present with subtle neurologic findings that are thought to represent growth of the lesion over time. Hemorrhage of an intramedullary hemangioblastoma presenting as acute neurologic deficit is an extremely rare occurrence. Although the cervical spine is the most common location for hemangioblastoma of the spinal cord, there have been no previously published cases in the literature of intramedullary hemorrhage from such a lesion. FINDINGS A 22-year-old woman with a previously undiagnosed spinal cord hemangioblastoma presented with sudden-onset dense quadriparesis due to intramedullary hemorrhage in the cervical spinal cord. The patient did not have any clinical findings of von-Hippel Lindau disease. Laminoplasty from C5 to T2 and posterior midline myelotomy for resection of the intramedullary tumor with hematoma evacuation were completed without complication. CONCLUSION Intramedullary hemangioblastoma of the spinal cord is uncommon, and hemorrhage from a cervical spinal cord lesion has not previously been reported. Symptoms from these usually indolent lesions are commonly associated with tumor growth, edema, or associated syrinx, whereas devastating acute neurologic deficit from hemorrhage is exceedingly rare. Microsurgical resection should be done in cases of symptomatic lesions and considered in isolated symptomatic lesions without the known diagnosis of von Hippel-Lindau disease.

Abstract
Intracranial ependymomas are rare tumors in adults. Thus, factors affecting prognosis are poorly understood. We performed a study to investigate whether tumor location is an important prognostic factor in adults who undergo surgery for intracranial ependymomas. PubMed was searched to identify studies that reported clinical outcomes in adult patients with intracranial ependymoma. Data were extracted for patient and tumor characteristics, extent of resection, progression-free survival (PFS), and overall survival (OS). Tumors were categorized as supratentorial or infratentorial and extraventricular or intraventricular. Presenting clinical features and tumor characteristics were tabulated. Kaplan-Meier and multivariate Cox regression survival analyses were performed to determine PFS and OS by tumor location. Extent of resection was also analyzed by tumor location. A total of 183 patients were included in the meta-analysis. Patients presented at a mean of 8.2months with a myriad of clinical features. The mean tumor size was 3.38 cm, and 19.3% of tumors were cystic. Supratentorial tumors were most commonly located in the frontal and parietal lobes, and infratentorial tumors in the fourth ventricle. Supratentorial tumors demonstrated significantly poorer PFS (p<0.001) and OS (p=0.003) than infratentorial tumors, despite a higher rate of gross total resection (GTR) for the supratentorial tumors (72.6% versus 42.1%). Extraventricular ependymomas displayed significantly poorer PFS than intraventricular ependymomas (p=0.009). In summary, supratentorial ependymomas have significantly poorer PFS and OS than their infratentorial counterparts, despite being more conducive to GTR, suggesting increased clinical aggressiveness. Extraventricular location is also associated with significantly poorer PFS than intraventricular location.

Abstract
INTRODUCTION Primary filum terminale ependymoma (PFTE) is a unique type of ependymomas and locates on extramedullary site. However, the clinical features and prognostic factors of PFTE are still unknown due to its rarity. AIM This study aimed to evaluate the clinical features, outcomes, and prognostic factors of PFTE in the largest series of cases. RESULT Thirty-eight patients were included in this study. Gross total removal (GTR) of the tumors was achieved in 33(87%) patients. Five (13%) patients had subtotal resection (STR). For the residual tumors, postoperative radiotherapy increased the interval between the first surgery and tumor regrowth (P = 0.063). Six patients had local recurrence/progression. Univariate analysis identified STR(P = 0.001), unencapsulated tumor (P = 0.018), tumor involving more than two vertebral columns (P = 0.005), and tumor invading sacral canal(P < 0.001) as predictors of tumor recurrence. In addition, 36 (95%) patients had stable or improved neurological status directly after surgery. Klekamp-Samii score was better correlated with the symptoms than McCormick scale. CONCLUSION Extent of surgical removal, tumor size, tumor location, and the integrity of tumor capsule are the prognostic factors of PFTEs, and the intrasacral PFTEs always have a poor prognosis.

Abstract
BACKGROUND Surgical treatment of spinal ependymomas requires careful consideration of the relative risks of neurological worsening from surgery. Our aim was to determine the risk factors of neurological deterioration after surgery for spinal ependymomas. MATERIAL AND METHODS This 20-year study included 17 patients (seven men and 10 women; 44.65±13.62 years) with histologically confirmed spinal ependymomas. The basic features were reviewed and the functional status was assessed by using the modified McCormick classification. We subdivided the patient population into two groups according to whether neurological deterioration occurred after primary tumor resection (N=5) or not (N=12), and compared their clinical characteristics. RESULTS The average duration of presenting symptoms in the 17 patients was 23.53±21.45 months. Three (17.6%) patients underwent subtotal or partial resection and 14 (82.4%) patients underwent gross total resection. The incidence of neurological deterioration after primary resection of spinal ependymomas was 29.4%. There were five (100%) and two (16.7%) male patients in the neurological-deterioration and no-deterioration groups, respectively (p=0.003). The duration of presenting symptoms was 24 months or over in all the patients with neurological deterioration and five of the 12 patients with improved or stabilized function (p=0.044). CONCLUSION The risk associated with surgical resection of spinal ependymomas should not be overlooked because of the significant incidence of neurological deterioration. The male gender and long-standing symptom (≥24 months) are risk factors of postoperative neurological worsening. Early diagnosis and surgery are therefore critical for successful treatment of spinal ependymomas.

Abstract
OBJECT Intramedullary capillary hemangiomas are exceedingly rare lesions in the spinal cord, and have been previously reported in the literature as case reports. The authors review their experience in 5 surgically treated patients with intramedullary capillary hemangiomas and discuss the clinical features, radiological findings, and surgical outcomes. METHODS Clinical and imaging data of 5 patients with intramedullary spinal capillary hemangiomas treated at a single institution were retrospectively analyzed. RESULTS There were 4 men and 1 woman, and their ages ranged from 18 to 63 years (mean 47.2 years). The thoracic cord was affected in 4 patients, and the cervicothoracic cord in 1 patient. Four patients underwent a gross-total resection. One patient initially underwent a subtotal removal and then underwent a second surgery due to enlargement of the residual lesion. Long-term neurological function was improved in all patients and MRI showed no tumor recurrence. CONCLUSIONS Capillary hemangiomas should be considered in the differential diagnosis of intramedullary spinal vascular lesions. Complete resection is the treatment of choice for these lesions. When total resection cannot be achieved, subtotal or even partial removal of the tumor is advised and repeat removal of the lesion is indicated when residual tumor regrowth is associated with neurological deterioration.

Abstract
AbstractBACKGROUND:Ependymomas constitute approximately 40% of primary intraspinal tumors. Current World Health Organization (WHO) grading may not correlate with observed progression-free survival (PFS).OBJECTIVE:This retrospective study of prospectively collected data examines whether PFS is influenced by the histological grade or by the extent of resection. It also analyzes the usage and effectiveness of postoperative adjuvant radiotherapy.METHODS:We reviewed 134 consecutive patients with ependymomas of all grades. Pathology slides were re-reviewed and the histological grades were confirmed by a single neuropathologist. Postoperative residual or recurrence was evaluated with follow-up magnetic resonance imaging.RESULTS:There were 85 male and 49 female patients, ranging from 10 to 79 (median 41) years of age. Thirty patients had WHO grade I tumors, 101 had grade II tumors, and 3 had grade III tumors. Kaplan-Meier analysis of PFS demonstrated a mean duration of 6 years for grade I, 14.9 years for grade II, and 3.7 years for grade III (P < .001). In grade II ependymomas, mean PFS was 11.2 years with subtotal resection and 17.8 years with gross total resection (P < .01). PFS of patients who underwent subtotal resection was not significantly changed by adjuvant radiotherapy (P < .36).CONCLUSION:Patients with grade II ependymoma have significantly longer PFS than patients with grade I ependymoma. The extent of resection did not affect PFS in grade I ependymoma but it did in grade II. Contrary to its higher grade, WHO grade II ependymoma carries a better prognosis than WHO grade I ependymoma.

Abstract
OBJECT Little is known regarding the anaplastic variant of primary ependymomas that involve the spinal cord. The aim of this study was to evaluate the clinical characteristics and treatment outcomes of primary spinal anaplastic ependymomas (PSAEs). METHODS Medical records were reviewed in 20 patients with pathologically proven PSAEs who underwent surgical treatment at the Department of Neurosurgery in Huashan Hospital between 1999 and 2008. RESULTS This series included 7 women and 13 men between the ages of 2 and 67 years (mean 31.9 years). The mean preoperative course was 9.3 months (range 20 days to 48 months). The most common PSAE locations were the cervical and thoracic spinal cords. The most common presenting symptom was weakness, followed by numbness, bowel or bladder dysfunction, and pain. Gross-total resection (GTR) was achieved in 17 patients, and a subtotal removal was performed in 3 patients. Nine patients received radiation therapy and/or chemotherapy. The mean follow-up duration was 83.5 months. Functional assessment of the 10 patients available at the latest follow-up evaluation showed that 2 had worsened and 8 remained unchanged from their preoperative status. There were 2 local recurrences and 1 lung metastasis. CONCLUSIONS Patients with PSAEs presented with a much shorter preoperative course than patients with Grade II ependymomas in previous studies. Patients with tumors that involved the cervical spinal cord experienced a worse outcome. Surgical removal of PSAEs, with the goal of GTR, is beneficial to patients. The role of radiation therapy and chemotherapy in PSAEs remains to be determined in further studies.

Abstract
The authors present a case of extensive primary intramedullary spinal CNS ganglioneuroblastoma (GNB) in a 23-year-old man. Central nervous system GNB is a poorly differentiated neuroepithelial tumor composed of neuroblasts and differentiated ganglion cells, and these lesions are extremely uncommon. Most previously reported primary intraaxial neuroblastic tumors were described in the brain. There has been only one other report of primary spinal cord CNS GNB published to date; the clinical course and prognosis for primary spinal cord tumors of this type are unknown. Similar tumor types demonstrate poor prognoses.
This 23-year-old man presented after 9 months of progressive myelopathy. Admission MR imaging showed an intraaxial enhancing mass extending from C-3 to the conus medullaris, with a holocord appearance in several areas. Due to the tumor size, operative intervention was initially limited to biopsy sampling. Chemotherapy resulted in histological maturation, but initial tumor regression was temporary. The patient suffered progressive quadriparesis, and neuroimaging demonstrated slow enlargement of the tumor and an associated syrinx. Nineteen months after diagnosis, the tumor was excised to gross-total resection in a 2-stage operation. One year following resection, the patient had no radiographic recurrence and was functional in a wheelchair with minimal paresis in the upper extremities. This case represents the most extensive example of primary spinal intramedullary CNS GNB reported to date. Holocord tumors present a significant challenge to the neurosurgeon, and resection bears substantial risk of morbidity. In spinal cord CNS GNB, chemotherapy followed by complete resection may be the most effective means of tumor control.

Abstract
Intramedullary tumors are rare. The authors reviewed 24 cases operated between 1996 and 2006. The study assessed the clinical characteristics and surgical results based upon the neurological function. METHOD: Medical records of patients with intramedullary astrocytoma and ependymoma were reviewed. The minimal follow up time was 6 months and, at the end of this period, a comparative analysis of the neurological function was performed based using the McCormick scale score. RESULTS: Most patients had astrocytoma (75%). Male gender was more prevalent (58.3%). The most common type of tumor was graded as I or II, and in three cases these were malignant. The total resection of the tumor was achieved in 20.8% of the cases. The statistical analysis did not show a statistically significant difference between preoperative and postoperative grades at McCormick scale. CONCLUSION: The authors concluded that microsurgery to intramedullary tumors did not significantly alter the neurological function after six months.

Abstract
OBJECTIVE To evaluate the clinical results of gross total resection in the surgical approach to spinal ependymoma. METHODS Between June 1995 and May 2009, 13 males and 8 females (mean age 34) diagnosed with intramedullary or extramedullary spinal ependymoma were surgically treated at our centre. The neurological and functional state of each patient were evaluated according to the modified McCormick scale. RESULTS The average follow-up duration was 54 months (ranging from 12 to 168 months). The locations of the lesions were: thoracic region (4, 19%), lumbar region (7, 34%), cervical region (4, 19%), cervicothoracic region (3, 14%) and conus medullaris (3, 14%). Four patients (19%) had deterioration of neurological function in the early postoperative period. The neurological function of three patients was completely recovered at the 6th postoperative month, while that of another patient was recovered at the 14th month. In the last assessment of neurological function, 20 patients (95%) were assessed as McCormick grade 1. No perioperative complications developed in any of our patients. In one patient's 24-month assessment, tumour recurrence was observed. Re-operation was not performed and the patient was taken under observation. CONCLUSION Two determinants of good clinical results after spinal ependymoma surgery are a gross total resection of the tumour and a good neurological condition before the operation. Although neurological deficits in the early postoperative period can develop as a result of gross total tumour resection, significant improvement is observed six months after the operation.

Abstract
UNLABELLED The frequency of intramedullary tumors is 0.5 cases per year for 100,000 inhabitants. The study reported herein was a retrospective study conducted from January 1985 to September 2007. MATERIAL Seventy-nine cases were distributed in the following manner: ependymomas, 38; astrocytomas, 22; oligodendrogliomas, four; gangliogliomas, two; hemangioblastomas, 10 (nine sporadic cases and one case of Von Hippel-Lindau disease); primitive melanoma, one; and intramedullary neurinomas, two. Three patients were lost to follow-up and 10 patients died. METHOD All patients were explored using MRI and were operated using a microsurgical technique. Tumor removal was complete in the cases of ependymoma and hemangioblastoma and subtotal in the cases of astrocytoma. RESULTS Ependymoma: 38 cases with three cases of ependymoblastoma. Mean age: 47 years (range, 17-74 years); 17 males and 21 females. Diagnostic delay: less than one year, 11; one year, 15 cases; two years, nine cases; three years, three cases. Seven recurrences with one 35 years after a prior removal. Localizations: cervical and cervicodorsal, 19; dorsal, ten; dorsolumbar, seven; holomedullary, one. Number of levels concerned: 5-12 (with the cysts associated). Mean follow-up was 10 years (range, two months to 35 years). Patients stabilized, 19; worse, six; improved, nine. Patients deceased: four, one by suicide, three cases of ependymoblastoma (survival, seven months). Astrocytomas: 22 cases, with 14 cases of astrocytoma, two pilocytic astrocytoma, four malignant astrocytoma, and two glioblastoma. Mean age: 44 years (range, 22-73 years); 14 males and eight females. Diagnostic delay: malignant tumors, one to nine months; low grades; three to six years (range, eight months to 25 years). Number of levels concerned: two to eight. Mean follow-up: seven years (range, six months to 10 years). Stabilized patients: 13; worse, five; deaths, four. Oligodendroglioma: four cases. Mean age: 58 years; two males and two females. Diagnostic delay: 10months. Localization: cervical, three; dorsal, one. Oligodendroglioma A, two; B, two. Results: two cases stabilized, one case with recurrence, and one patient deceased. Ganglioglioma: two. Both cases were associated with scoliosis. Recurrence in the eighth month and two years for the second case. One patient died. Hemangioblastoma: 10 cases, nine sporadic and one case of Von Hippel-Lindau disease. Nine cervical localizations, one on the medulla cone. Mean age: 45 years (range, 11-54 years); eight males and two females. Total removal in nine cases. One case of recurrence seven years after a prior surgery and operated a second time with no recurrence after 10 years of follow-up. Intramedullary neurinomas: two cases with a total removal and 15 years of follow-up. Primitive melanoma: one case with mediothoracic location. Treatment with surgery plus radiotherapy. Follow-up, seven years without recurrence. CONCLUSION Total removal of the intramedullary tumors is a challenge. In cases of removal, the risk of worsening status is 18-19.5%. Subtotal or incomplete removal 27-40% risk of recurrence.

Abstract
Non-neoplastic intramedullary spinal lesion cases are rarely seen in the literature. We would like to present this case for differential diagnosis of intramedullary spinal tumors. The aim of this case report is to attract attention on the MRI findings with lack of contrast enhancement and long syrinx formation which differs these types of lesions from the intramedullary spinal tumors. Intraoperative, pathological and immunohistochemical findings of non-neoplastic intramedullary spinal lesion were discussed.

Abstract
Capillary hemangiomas are benign vascular neoplasms. When associated with the spine, these growths frequently involve the vertebral body, but rarely have they been reported to occur as intradural lesions, while even more rarely occurring in a true intramedullary location. We report a rare case of an intramedullary capillary hemangioma of the thoracic spinal cord and a review of the literature.

Abstract
STUDY DESIGN Case report. OBJECTIVE To report a very unusual spinal meningioma, mimicking an intramedullary spinal tumor. SUMMARY OF BACKGROUND DATA Spinal meningiomas, usually associated with signs and symptoms of cord or nerve root compression, are generally encountered in women aged over 40. Radiologic diagnosis is often established by their intradural extramedullary location on magnetic resonance images. METHODS A 60-year-old woman had a 6-month history of progressive weakness in her upper extremities, difficulty in walking, and cervical pain radiating through both arms. Neurologic examination revealed motor strength deficiency in all her extremities, with extensor reflexes, clonus, and bilateral hyper-reflexiveness. A sensory deficit was present all over her body. Magnetic resonance images revealed that the spinal cord appeared expanded with an ill-defined, homogeneously contrast-enhanced, lobulated, eccentric mass at the C1-C3 level. The patient was operated with a preliminary diagnosis of an intramedullary tumor. RESULTS At surgery, the mass was found to be extramedullary, and gross total resection was performed. Histopathological examination revealed a meningioma characterized by the presence of fibrous and meningothelial components. The patient was able to ambulate with a cane, and extremity strength and sensation improved 2 months after surgery. CONCLUSION Spinal meningiomas can mimic intramedullary tumors, and should be considered in differential diagnosis of intradural tumors with atypical appearance.

Abstract
We report a divergent ependymal tumor of the posterior fossa (ependymoblastoma/anaplastic ependymoma) observed in an 8-year-old boy. The tumor showed the histological pattern typical of an ependymoblastoma (tubular-papillary fetaloid architecture with stratification of the tumor cells) next to areas in which findings typical of an anaplastic ependymoma were detected. The immunohistochemical study confirmed our diagnostic suspicion, allowing us to establish a differential diagnosis with other entities such as medulloblastoma, medulloepithelioma, atypical rhabdoid/teratoid tumor, or metastases.

Abstract
BACKGROUND Population-based data on the familial risk for vascular tumors are largely lacking. Such data are important for clinical counseling and cancer genetics. METHODS We used the Swedish Family-Cancer Database to calculate standardized incidence ratios for specific subtypes of vascular tumors in offspring using parents as probands. In addition, risks for second cancers were analyzed. RESULTS Offspring hemangioblastoma in the nervous system was associated with parental kidney cancer and nervous system hemangioblastoma and hemangioma. Offspring nervous system hemangiopericytoma was associated with parental pituitary adenomas. Offspring angiosarcoma in the trunk and extremities was associated with maternal breast cancer. Second Kaposi's sarcoma, non-Hodgkin's lymphoma, Hodgkin's disease and myeloma were increased following primary skin Kaposi's sarcoma. Kidney and endocrine gland tumors and nervous system hemangioblastomas and hemangiomas were in excess following primary nervous system hemangioblastoma and hemangioma. CONCLUSIONS Our data showed that familial clustering of nervous system hemangioblastoma and hemangioma and the risks of subsequent cancers were primarily related to von-Hippel-Lindau disease. As a novel association, offspring nervous system hemangiopericytomas were in excess when parents were diagnosed with pituitary adenoma. Similarly, offspring angiosarcoma is associated with maternal breast cancer. Immunodeficiency may explain the excess of lymphoproliferative diseases after skin Kaposi's sarcoma.
