Abstract
Spinal cord hemangiomas are rare vascular malformations that can cause neurological deficits. We report a case of a 57-year-old male who previously underwent spondylolisthesis reduction for treatment of a 30% (1 cm) anterolisthesis of L4-L5 with continued neurological deficit post-operatively. The patient still reported bilateral lower extremity weakness, and he was found to have an additional ovoid intramedullary lesion at the T2-T3 level, pathologically consistent with a hemangioma. The patient underwent a T2-T3 laminectomy, and the lesion was resected without any complications. Histopathological examination confirmed the diagnosis of hemangioma. Postoperatively, the patient showed significant improvement in his lower extremity weakness and back pain. Hemangiomas are rare lesions that account for less than 5% of all spinal cord tumors. They consist of vessels similar to those of embryonic capillaries and can cause pressure on the surrounding neural tissue, leading to neurological deficits. MRI is the imaging modality of choice for diagnosing spinal cord hemangiomas. Hemangiomas typically demonstrate mixed signal intensities on T1-weighted images, depending on the fat content of the lesion. They usually demonstrate high T2 signal intensity due to high water content, and avid contrast enhancement due to high vascularity. Surgical resection is the treatment of choice for symptomatic hemangiomas, and complete resection is associated with a good prognosis.

Abstract
BACKGROUND Spinal tumors are rare pathology in the pediatric population. The tumors can be classified as extradural, intradural extramedullary, or intramedullary. Any of the spinal tumors can eventually lead to spinal deformity. The progressive spinal deformity can be part of the initial presentation or evolve on long follow-up, even years after the initial intervention and treatment. SUMMARY Management of spinal deformity associated with spinal tumors in children is not well defined. Patients with progressive symptoms and even neurological deficits need correction for their deformity when diagnosed. Patients that do not have pain or related neurological deficits should be evaluated for the severity of their deformity and followed long-term. Special consideration is needed for young patients who need multilevel surgery or have deformity at presentation. KEY MESSAGES When considering the need for instrumentation and fusion, the surgeon should consider the age of the patient, expected future growth of the spine, neurologic status, extent of initial deformity, and the number of vertebral levels involved by tumor. Providers should also consider how surgery may fix or prevent deformity, especially when instrumentation can affect imaging at follow-up.

Abstract
Objective: Long-level intramedullary spinal cord tumors (LIMSCTs) cause complex treatment issues. However, LIMSCTs have rarely been analyzed separately. The authors reported a large case series of LIMSCTs and analyzed the clinical characteristics and treatment outcomes.Methods: The medical data of patients with LIMSCTs at our institution between January 2015 and December 2019 were retrospectively reviewed. Demographics, tumor size and location, pathology, extent of resection, and neurological functional status were collected.Results: A total of 43 consecutive cases were included. Twenty-three cases (53.5%) of LIMSCTs were ependymal tumors. All patients with ependymal tumors achieved gross total resection (GTR). In ependymal tumor cases, 3 cases (13%) of ependymal tumors experienced postoperative neurological deterioration, and 66% of them showed an improvement at follow-up; 25.6% were low-grade astrocytic tumors. The rates of GTR, subtotal resection (STR) and partial resection (PR) were 63.6%, 27.3%, and 9.1%, respectively. Twenty-seven percent cases showed postoperative neurological worsening, and 33% of them had an improvement at follow-up; 20.9% were high-grade astrocytic tumors. The excision rates were 44.4% for GTR, 44.4% for STR, and 11% for PR, respectively. Fifty-five percent cases showed postoperative neurological worsening, and none of them had an improvement at follow-up.Conclusion: In this series, all LIMSCTs were gliomas. Aggressive tumor resection did not increase the risk of long-term functional deterioration in ependymal tumors and low-grade astrocytic tumors, but in high-grade astrocytic tumors, patients had a higher risk of neurological deterioration and difficulty in recovery. In ependymal tumors and low-grade astrocytic tumors, patients can achieve long-time survival after performing aggressive tumor resection.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES Intraspinal solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) is often misdiagnosed preoperatively as schwannoma or meningioma because its imaging characteristics are not well understood. As postoperative prognosis differs among the 3 lesions, predicting the probability of SFT/HPC preoperatively is essential. Thus, this study investigates the imaging characteristics of SFT/HPC compared with those of schwannoma or meningioma and evaluates surgical outcomes. METHODS The preoperative imaging findings, tumor resection extent, recurrence and regrowth rates, and neurological improvement were compared between 10 patients with SFT/HPC and 42 patients with schwannoma or 40 patients with meningioma. RESULTS Most patients with SFT/HPC showed isointensity on both T1- and T2-weighted images compared with patients with schwannoma (P = 0.011 and 0.029, respectively) and no significant difference compared with patients with meningioma (P = 0.575 and 0.845, respectively). Almost all patients with SFT/HPC showed highly uniformizing enhancement patterns, similar to those with meningioma (P = 0.496). Compared with meningioma, SFT/HPC lacked the dural tail sign and intratumoral calcification and exhibited irregular shape. Of the 5 patients who underwent partial resection, 60% exhibited tumor recurrence and regrowth following surgery. CONCLUSIONS Complete en bloc surgical resection should be attempted in patients with intraspinal SFT/HPC to prevent postoperative recurrence or regrowth. As this tumor is often preoperatively misdiagnosed, we recommend that the imaging findings exhibited in this study should be used to positively suspect SFT/HPC. This will enhance patient outcomes by enabling more appropriate preoperative surgical planning.

Abstract
Malignant spinal tumors constitute around 22% of all primary spinal tumors. The most common location of metastases to the spinal region is the extradural compartment. The molecular and genetic characterization of these tumors was the basis for the updated WHO classification of CNS tumors in 2016, where many CNS tumors are now diagnosed according to their genetic profile rather than relying solely on the histopathological appearance. Magnetic resonance imaging (MRI) is the current gold standard for the initial evaluation and subsequent follow-up on intradural spinal cord tumors, and the imaging sequences must include T2-weighted images (WI), short time inversion recovery (STIR), and pre- and post-contrast T1-WI in the axial, sagittal, and coronal planes. The clinical presentation is highly variable and depends on the tumor size, growth rate, type, infiltrative, necrotic and hemorrhagic potential as well as the exact location within the spinal compartment. Surgical intervention remains the mainstay of management of symptomatic and radiographically enlarging spinal tumors, where the goal is to achieve maximal safe resection. Tumor recurrences are managed with repeat surgical resection (preferred whenever possible and safe), radiotherapy, chemotherapy, or any combination of these therapies.

Abstract
Alert criteria breaches occur frequently and are reversed following intervention during complex paediatric cervical spine surgery. All patients with worsening sensorimotor function had irreversible alert criteria breaches. Evoked potential amplitude reduction may provide an early warning to worsening sensorimotor function.
Objective To determine the utility of widely used intraoperative neuromonitoring (IONM) alert criteria and intervention for predicting postoperative outcome following paediatric spinal surgery. Methods Retrospective analysis of somatosensory evoked potentials (SSEP) and motor evoked potentials (MEP) in consecutive cervical spine fixations. An intervention protocol followed amplitude-reductions in SSEPs (≥50 %) and/or MEPs (≥80 %). Alert breaches were reversed when SSEP/MEP amplitude was restored to > 50 %/20 % of baseline. Sensorimotor function was assessed preoperatively and 3-months postoperatively via the Modified McCormick Scale score (MMS). We explored associations between postoperative outcome, demographic/surgical and IONM variables. Results Forty-five procedures in 38 children (mean age:9 ± 4 years;55 % female) were monitored, 42 %of which breached alert criteria. Instrumentation (6/19,32 %) and hypotension (5/19,26 %) were common causes for alert and the majority (13/19,68 %) were reversed following intervention. There was an association between pre- and post-MMS and the type of breach (p = 0.002). All children with worse postoperative MMS (3/38,8%) had irreversible breaches. Conclusions IONM in this small sample accurately detected neurological injury. The majority of breaches reversed following an intervention protocol. Irreversible breaches frequently led to worse postoperative sensorimotor function. Significance An intervention protocol which reversed IONM alerts never resulted in postoperative worsening of sensorimotor function.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES Although intramedullary astrocytoma is associated with a high mortality rate, the optimal treatment has not reached a consensus. This study aimed at evaluating neurologic function and overall survival rate (OSR) in the treatment of this tumor. SETTING The single institution in Japan. METHODS This study enrolled 67 subjects who underwent surgical treatment for intramedullary astrocytoma. Demographic, imaging, and surgical information were collected from each participant. Tumors were histologically categorized using the World Health Organization classification, and subjects were divided into low-grade (I and II; n = 40) and high-grade (III and IV; n = 27) groups. Neurologic status was evaluated using the modified McCormick scale (MMS). OSR was assessed using Kaplan-Meier methods. RESULTS The OSR decreased when the pathological grade increased (p < 0.01). Regarding the therapeutic efficacy for low-grade astrocytomas, subjects who underwent gross total resection (GTR) showed a higher OSR than those who did not (p = 0.02). GTR prevented worsening of MMS score, while non-GTR increased the MMS score (p < 0.01). In the high-grade group, 19 and 10 underwent radiation therapy and chemotherapy, respectively. However, both treatments did not improve OSR. Cordotomy was performed for subjects whose lesional area was at the thoracic level, but the OSR did not significantly increase. CONCLUSIONS The most beneficial therapeutic strategy for low-grade astrocytomas was GTR, whereas that for the high-grade tumors was unclear. Further studies with a larger sample size are warranted to validate the effective treatment for malignant astrocytomas.

Abstract
Spinal epidural lipomatosis (SEL) is a rare condition caused by hypertrophic growth of epidural fat. The prevalence of SEL in the Western world is approximately 1 in 40 patients and is likely to increase due to current medical and socio-economic developments. Rarely, SEL can lead to rapid severe neurological deterioration. The pathophysiology, optimal treatment, and outcome of these patients remain unclear. This study aims to widen current knowledge about this “SEL subform” and to improve its clinical management. A systematic literature review according to the PRISMA guidelines using PubMed, Scopus, Web of Science, and Cochrane Library was used to identify publications before 7 November 2021 reporting on acute/rapidly progressing, severe SEL. The final analysis comprised 12 patients with acute, severe SEL. The majority of the patients were male (9/12) and multimorbid (10/12). SEL mainly affected the thoracic part of the spinal cord (11/12), extending a median number of 7 spinal levels (range: 4–19). Surgery was the only chosen therapy (11/12), except for one critically ill patient. Regarding the outcome, half of the patients regained independence (6/11; = modified McCormick Scale ≤ II). Acute, severe SEL is a rare condition, mainly affecting multimorbid patients. The prognosis is poor in nearly 50% of the patients, even with maximum therapy. Further research is needed to stratify patients for conservative or surgical treatment.

Abstract
Objective: Spinal cord ependymomas account for 3–6% of all central nervous system tumors and around 60% of all intramedullary tumors. The aim of this study was to analyze the neurological outcome after surgery and to determine prognostic factors for functional outcome. Patients and Methods: Patients treated surgically due to a spinal cord ependymoma between 1990 and 2018 were retrospectively included. Demographics, neurological symptoms, radiological parameters, histopathology, and neurological outcome (using McCormick Score [MCS]) were analyzed. Possible prognostic factors for neurological outcome were evaluated. Results: In total, 148 patients were included (76 males, 51.4%). The mean age was 46.7 ± 15.3 years. The median follow-up period was 6.8 ± 5.4 years. The prevalence was mostly in the lumbar spine (45.9%), followed by the thoracic spine (28.4%) and cervical spine (25.7%). Gross-total resection was achieved in 129 patients (87.2%). The recurrence rate was 8.1% and depended on the extent of tumor resection (p = 0.001). Postoperative temporary neurological deterioration was observed in 63.2% of patients with ependymomas of the cervical spine, 50.0% of patients with ependymomas of the thoracic spine, and 7.4% of patients with ependymomas of the lumbosacral region. MCS 1–2 was detected in nearly two-thirds of patients with cervical and thoracic spinal cord ependymoma 36 months after surgery. Neurological recovery was superior in thoracic spine ependymomas compared with cervical spine ependymomas. Poor preoperative functional condition (MCS >2), cervical and thoracic spine location, and tumor extension >2 vertebrae were independent predictors of poor neurological outcome. Conclusion: Neurological deterioration was seen in the majority of cervical and thoracic spine ependymomas. Postoperative improvement was less in thoracic cervical spine ependymomas compared with thoracic spine ependymomas. Poor preoperative status and especially tumor extension >2 vertebrae are predictors of poor neurological outcome (MCS >2).

Abstract
OBJECTIVE The histopathology of intramedullary spinal cord tumors (IMSCT) can be suspected from the MRI features and characteristics. Ultimately, the confirmation of diagnosis requires surgery. This retrospective study addresses MRI features including homogeneity of enhancement, margination, and associated syrinx in intramedullary astrocytomas (IMA) and ependymomas (IME) that assist in diagnosis and predict resectability of these tumors. METHODS Single-center retrospective analysis of IMA and IME cases since 2005 extracted from the departmental registry/electronic medical records post IRB approval (IRB 201,710,760). We compared imaging findings (enhancement, margination, homogeneity, and associated syrinxes) between tumor types and examined patient outcomes. RESULTS There were 18 IME and 21 IMA. On preoperative MRI, IME was favored to have homogenous enhancement (OR 1.8, p = 0.0001), well-marginated (p < 0.0001, OR 0.019 [95 % CI 0.002-0.184]), and associated syrinx (p = 0.015, OR 0.192 [95 % CI 0.049-0.760]). Total excision, subtotal excision, and biopsy were performed in 12, 5, and 1 patients in the IME cohort, respectively. In the IMA group, tumors were heterogeneous and poorly marginated in 20 of the 21 patients. Total excision, subtotal excision, and biopsy were undertaken in 2, 13, and 6 patients, respectively. The success of excision was predicted by MRI, with a significant difference in the extent of resection between IME and IMA (X2 = 14.123, p = 0.001). In terms of outcome, ordinal regression analysis showed that well-margined tumors and those with homogeneous enhancement were associated with a better postoperative McCormick score. Extent of resection had statistically significant survival (p = 0.026) and recurrence-free survival (p = 0.008) benefits. CONCLUSION The imaging characteristics of IME and IMA have meaningful clinical significance. Homogeneity, margination, and associated syrinxes in IME can predict resectability and complexity of surgery.

Clinical characteristics and surgical outcomes of ependymomas in the upper cervical spinal cord: a single-center experience of 155 consecutive patients. Neurosurg Rev 2020; 44:1665-1673. [PMID: 32767042 DOI: 10.1007/s10143-020-01363-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 07/08/2020] [Accepted: 07/28/2020] [Indexed: 11/24/2022]
Abstract
Ependymomas occurring in the upper cervical spinal cord (above the level of the C4 segment) are rare entities with great therapeutic challenges. This study was aimed to investigate the clinicoradiological characteristics and the prognosis in a large cohort of upper cervical ependymomas from a single institution. This retrospective study enrolled 155 patients with primary ependymomas in the upper cervical spinal cord. The pre- and post-operative clinical and magnetic resonance imaging profiles were collected. The neurological outcomes and survival events were evaluated, and potential independent risk factors were analyzed. There were 82 females and 73 males, with an average age of 43.1 ± 11.3 years. Immediately post-operatively, 118 (76.1%) patients experienced neurological deterioration and 32 (20.7%) patients remained unchanged. Three months after surgery, 61 (39.4%) patients showed deteriorated neurological functions compared to the pre-operative baseline levels. After an average follow-up period of 56.0 ± 24.7 months, the neurological functions were worse than the baseline status in 37 (23.9%) patients and improved in 33 (21.3%) patients, respectively. Logistic regression analysis identified that lower age (≤ 42 years) and lower pre-operative MMS (I-II) were independent protective factors for predicting favorable neurological functions. Multivariate Cox regression analysis revealed that incomplete resection was the only independent risk factor associated with a shorter progression-free survival. Age and pre-operative functional status affect the long-term neurological outcomes, and incomplete resection was associated with a shorter survival. Our findings indicate that gross total resection should be the goal of surgical treatment of upper cervical ependymomas.

Abstract
OBJECTIVE To identify the risk factors for recurrence of World Health Organization (WHO) grade Ⅱ ependymomas of spinal cord in adults after microsurgical resections. PATIENTS AND METHODS A total of 118 adult patients diagnosed with WHO grade Ⅱ ependymomas of spinal cord at west china hospital from January 2010 to December 2016 were reviewed retrospectively. To identify the risk factors for recurrence, we performed univariate analyses and multivariate logistic regression analyses successively. RESULTS Twelve patients had a recurrence with a median recurrence time of 30 months [inter-quartile range (IQR) 23.5-75.5 months]. Univariate analysis showed that age (p = 0.030), STR (p < 0.001), index of Ki-67 (p = 0.004), and Vimentin (+, p = 0.004) were associated with postoperative recurrence of ependymomas of spinal cord in adults, while univariate analysis showed that only STR [odds ratio (OR) = 18.838, 95 % confidence interval (CI): 3.068-115.673; p = 0.002], index of Ki-67 (OR = 1.381, 95 % CI: 1.021-1.868; p = 0.036), Vimentin (+; OR = 6.706, 95 % CI: 1.218-36.928; p = 0.029) were independent risk factors for recurrence. CONCLUSIONS The recurrence rate of WHO grade Ⅱ ependymomas of spinal cord in adults was about 13.6 %. Subtotal resection is a critical risk factor for recurrence. A high index of Ki-67 is another independent risk factor for recurrence. Positive Vimentin may also play a role in this process. GTR is very important to prevent recurrence after operation if it is safe to conduct. In cases with higher index Ki-67 and Vimentin (+), close follow-ups are necessary.

Abstract
INTRODUCTION Primary paragangliomas (PG) of the spine are extremely rare entities. The present study reviews our experience over a period of 30 years. METHODS This is a retrospective, single center, observational study. Patients surgically treated for a spinal PG with confirmed anatomopathological diagnosis were included. The McCormick classification was used as a reference for clinical evaluation. Follow-up MRI and clinical assessment took place at 6 weeks, 3 months, 6 months, and 1 year after surgery and on yearly basis after. RESULTS Six cases have been operated in our institution. The mean age was 37.8 (median 35.5, 30-53). The mean follow-up period was 9.6 years (median 9.5, 1-23). Preoperative duration of symptoms varied between a few hours to 4 years. Low back pain was most common sign. One presented with hemorrhage and acute onset of paraplegia. All patients underwent single surgery, with the exception of one case, which had two surgeries on the same anatomical site and a third surgery on another location of the same tumor type. Preoperatively, McCormick scale was I in four cases, and II and IV in one case, respectively. Postoperatively, all patients in McCormick I retained the same class; one patient in McCormick II passed to McCormick III; the case in McCormick IV recovered to McCormick II. Five of eight surgeries achieved total resection, while two surgeries accomplished a partial microsurgical excision and one a gross total resection. Three patients had spinal leptomeningeal dissemination. Two of them benefited from extended spine radiotherapy, while the other of a "wait-and-scan" policy. Spinal leptomeningeal dissemination was stable in all patients at last follow-up. CONCLUSION We consider surgery as primary treatment in all PG. In our experience, preoperative diagnosis is difficult and caution must be taken to perioperative course in these cases. We do not routinely perform postoperative radiation if there is a residual tumor. We regularly perform clinical and radiological follow-up, so as to be able to document recurrent cases, which have been reported even up to 30 years after primary surgical excision.

Abstract
PURPOSE Most pediatric spinal tumors are low-grade gliomas (LGGs). Characterization of these tumors has been difficult given their heterogeneity and rare incidence. The objective was to characterize such tumors diagnosed at our institution. METHODS Spinal tumors diagnosed in our pediatric patients between 1984 and 2014 were reviewed retrospectively. Demographics, presentation, pathology, imaging, management, and sequelae were examined. RESULTS Forty patients had spinal LGG tumors, 24 (62%) of which were pilocytic astrocytomas. The most common initial presentations were pain (n = 15), partial extremity paralysis (n = 13), and ataxia (n = 11), with the diagnosis frequently delayed by months (median = 5.9 months, range 4 days-6.2 years). Twenty-nine patients had some tumor resection, and 8 required adjuvant therapy with chemotherapy (n = 4) or radiation (n = 4) post-resection. Ten other patients received only biopsy for histologic diagnosis, who were treated with chemotherapy (n = 4) or radiation (n = 5) post biopsy. Tumor progression was noted in 16 patients (2 after gross-total resection; 10, partial resection; and 4, biopsy). During the evaluation period, 3 patients died secondary to tumor progression. BRAF status could have shortened progression-free survival: patients with BRAFV600E mutations (n = 3) all experienced progression within 10 months. Long-term sequelae of the disease/treatment were mostly residual neurologic deficits (paresthesia, paralysis), chemotherapy-induced hearing loss, and scoliosis. CONCLUSIONS Spinal LGG is a rare entity with significant long-term effects. Although surgery is the most common initial treatment option, more in-depth analysis of molecular biomarkers may improve stratification and prognostication.

Abstract
OBJECTIVE Intramedullary cavernous hemangioma (CH) is a rare vascular lesion that is mainly characterized by the sudden onset of hemorrhage in young, asymptomatic patients, who then experience serious neurological deterioration. Despite the severity of this condition, the therapeutic approach and timing of intervention for CH remain matters of debate. The aim of this study was to evaluate the clinical characteristics of CH patients before and after surgery and to identify prognostic indicators that affect neurological function in these patients. METHODS This single-center retrospective study included 66 patients who were treated for intramedullary CH. Among them, 57 underwent surgery and 9 patients received conservative treatment. The authors collected demographic, symptomology, imaging, neurological, and surgical data. Univariate and multivariate logistic regression analyses were performed to identify the prognostic indicators for neurological function. RESULTS When comparing patients with stable and unstable gait prior to surgery, patients with unstable gait had a higher frequency of hemorrhagic episodes (52.4% vs 19.4%, p = 0.010), as assessed by the modified McCormick Scale. The lesion was significantly smaller in patients who underwent conservative treatment compared with surgery (2.5 ± 1.5 mm vs 5.9 ± 4.1 mm, respectively; p = 0.024). Overall, the patients experienced significant neurological recovery after surgery, but a worse preoperative neurological status was identified as an indicator affecting surgical outcomes by multivariate analysis (OR 10.77, 95% CI 2.88–40.36, p < 0.001). In addition, a larger lesion size was significantly associated with poor functional recovery in patients who had an unstable gait prior to surgery (8.6 ± 4.5 mm vs 3.5 ± 1.6 mm, p = 0.011). CONCLUSIONS Once a hemorrhage occurs, surgical intervention should be considered to avoid recurrence of the bleeding and further neurological injury. In contrast, if the patients with larger lesion presented with worse preoperative functional status, surgical intervention could have a risk for aggravating the functional deficiencies by damaging the thinning cord parenchyma. Conservative treatment may be selected if the lesion is small, but regular neurological examination by MRI is needed for assessment of a change in lesion size and for detection of functional deterioration.

Abstract
PURPOSE The aim of this study was to thoroughly analyze the clinical characteristics of a large cohort of spinal meningioma (SM) from a single neurological center and identify risk factors associated with worse progression free survival and neurological function outcome. METHODS Clinical information was retrieved from 483 SM and 9806 cranial meningioma cases who were operated in our center between 2003 and 2013. 194 SM patients who were followed at the main branch were used for prognostic analyses that included both recurrence free survival and neurological functions based on Modified McCormick scale (MMS). RESULTS Females were predominant (P < 0.001). High grade tumors were not common (WHO grade II, 2.9%; grade III, 1.7%), while the clear cell subtype was frequent within grade II SMs (6/14, 42.9%). Macroscopic total resection was achieved in all SMs (Simpson grade I, 30.9%; grade II, 65.5%; grade III, 3.6%) with a low complications rate (4.6%) and provided neurological improvement in 80 patients (41.2%). Recurrence was seen in 9 cases (4.6%) and associated with high WHO grade, male, prior recurrence, and Simpson grade III. High WHO grade and high Ki-67 index were identified to be independent factors predictive of both neurological function deterioration and impaired post-operative neurological status. CONCLUSIONS Our analysis of the largest SM cohort in scale from a single institution offers a comprehensive view of the clinical characteristics of surgically treated SM, revealing the distinct biology of SM in comparison to its cranial counterparts, and providing guidance to improve surgical management of SM.

OBJECTIVE Spinal ependymomas are rare glial neoplasms. Because their incidence is low, only a few larger studies have investigated this condition. There are no clear data concerning prognosis and therapy. The aim of the study was to describe the natural history, perioperative clinical course, and local tumor control of adult patients with spinal ependymomas who were surgically treated under modern treatment standards. METHODS The authors performed a multicenter retrospective study. They identified 158 adult patients with spinal ependymomas who had received surgical treatment between January 2006 and June 2013. The authors analyzed the clinical and histological aspects of these cases to identify the predictive factors for postoperative morbidity, tumor resectability, and recurrence. RESULTS Gross-total resection (GTR) was achieved in 80% of cases. At discharge, 37% of the patients showed a neurological decline. During follow-up the majority recovered, whereas 76% showed at least preoperative status. Permanent functional deterioration remained in 2% of the patients. Transient deficits were more frequent in patients with cervically located ependymomas (p = 0.004) and in older patients (p = 0.002). Permanent deficits were independently predicted only by older age (p = 0.026). Tumor progression was observed in 15 cases. The 5-year progression-free survival (PFS) rate was 80%, and GTR (p = 0.037), WHO grade II (p = 0.009), and low Ki-67 index (p = 0.005) were independent prognostic factors for PFS. Adjuvant radiation therapy was performed in 15 cases. No statistically relevant effects of radiation therapy were observed among patients with incompletely resected ependymomas (p = 0.079). CONCLUSIONS Due to its beneficial value for PFS, GTR is important in the treatment of spinal ependymoma. Gross-total resection is feasible in the majority of cases, with acceptable rates of permanent deficits. Also, Ki-67 appears to be an important prognostic factor and should be included in a grading scheme for spinal ependymomas.

Abstract
BACKGROUND Spinal meningiomas are common spinal tumors, in most cases benign and with a good surgical prognosis. However, specific location, infiltration of spinal cord, vascular encasement, or spinal root involvement can bring a less favorable prognosis. OBJECTIVE To correlate these data with clinical/functional outcome. METHODS Two hundred twenty-four consecutive patients with spinal meningiomas treated from 1976 to 2013 in our institution were analyzed; among these, 51 were excluded for incomplete clinical data or follow-up. The remaining 173 cases were classified in regards to sex, age, symptoms, axial location, Simpson grade resection, and functional pre-/postoperative status. RESULTS Most recurring onset symptoms were pain (32.9%) and motor deficit (31.8%); thoracic spine was the most severely affected (69.8%). Functional improvement on the follow-up was observed in 86.7% of cases; 6.4% of patients resulted stable and 6.9% worsened. A low functional grade before surgery was connected to a lesser improvement after. Anterolateral meningiomas were the most represented (42.2%); a gross total resection (Simpson grades I and II) was conducted in 98.8%, and a macroscopically complete removal without dural resection or coagulation (Simpson grade III) was performed in 1.2%. Of the meningiomas, 98.3% were classified as WHO grade I. Recurrence rate was 2.3%, and 7 cases presented complications (4 of 7 required surgical procedure). CONCLUSION We can affirm that negative prognostic factors in our study were anterior or anterolateral axial location, prolonged presentation before diagnosis, WHO grade >I, Simpson grade resections II and III, sphincter involvement, and worse functional grade at onset.

Abstract
OBJECTIVE Spinal cord astrocytoma with intracranial dissemination carries a poor prognosis. The mechanisms leading to dissemination remain to be elucidated. A stem cell marker, CD133, was reported to predict recurrence patterns in intracranial glioblastoma. We evaluated the significance of CD133 as a putative prognostic biomarker to predict intracranial dissemination in spinal cord astrocytoma. METHODS This study included 14 consecutive patients with primary spinal cord astrocytoma treated from 1998 to 2014. Six of the patients were women and the patients' ages ranged from 12 to 75 years. Seven and 6 patients underwent open biopsy and partial resection of the tumors, respectively. After confirmation of the histologic diagnoses, all patients were treated with postoperative radiotherapy, chemotherapy, or a combination of both. To identify factors predictive of intracranial dissemination, we analyzed their clinical data including Ki-67 labeling index, and CD133 expression. RESULTS Intracranial dissemination was observed in 6 of 14 patients. All 6 patients died during the follow-up period. Of the 8 patients without intracranial dissemination, 5 survived (P = 0.02). Median survival for the patients with intracranial dissemination was 22.7 months. CD133 expression was significantly higher in patients with intracranial dissemination (P = 0.04), whereas other variables did not indicate the dissemination. CONCLUSIONS The expression of CD133 can be an efficient biomarker to predict intracranial dissemination in spinal cord astrocytoma. Recognition of high CD133 expression in surgical specimens and early detection of intracranial dissemination is important for the clinical management of spinal cord astrocytoma.

Abstract
The aim of the present study was to validate a therapy-oriented complication grading system in a well-defined neurosurgical patient population in which complications may entrain neurological deficits, which are severe but not treated. The prospective patient registry of the Department of Neurosurgery, University of Zurich provides extensive population-based data. In this study we focused on complications after lumbar spine surgeries and rated their severity by Clavien-Dindo grade (CDG). Analyzing 138 consecutive surgeries we noted 44 complications. As to treatment, CDG correlated with the length of hospital stay and treatment cost. As to patient outcome, CDG correlated with performance and outcome (McCormick). The present study demonstrates the correlation between outcome scales and the CDG. While the high correlation of CDG with costs seems self-evident, the present study shows this correlation for the first time. Furthermore, the study validates the CDG for a surgical subspecialty. As a further advantage, CDG registers any deviation from the normal postoperative course and allows comparison between surgical specialties.

Abstract
STUDY DESIGN A retrospective analysis of a prospective database. OBJECTIVE To compare preoperative symptoms, ambulatory ability, intraoperative spinal cord monitoring, and pathologic cell proliferation activity between intramedullary only and intramedullary plus extramedullary hemangioblastomas, with the goal of determining the optimal timing for surgery. METHODS The subjects were 28 patients (intramedullary only in 23 cases [group I] and intramedullary plus extramedullary in 5 cases [group IE]) who underwent surgery for spinal hemangioblastoma. Preoperative symptoms, ambulatory ability on the McCormick scale, intraoperative spinal cord monitoring, and pathologic findings using Ki67 were compared between the groups. RESULTS In group IE, preoperative motor paralysis was significantly higher (100 versus 26%, p < 0.005), the mean period from initial symptoms to motor paralysis was significantly shorter (3.5 versus 11.9 months, p < 0.05), and intraoperative spinal cord monitoring aggravation was higher (65 versus 6%, p < 0.05). All 5 patients without total resection in group I underwent reoperation. Ki67 activity was higher in group IE (15% versus 1%, p < 0.05). Preoperative ambulatory ability was significantly poorer in group IE (p < 0.05), but all cases in this group improved after surgery, and postoperative ambulatory ability did not differ significantly between the two groups. CONCLUSIONS Intramedullary plus extramedullary spinal hemangioblastoma is characterized by rapid preoperative progression of symptoms over a short period, severe spinal cord damage including preoperative motor paralysis, and poor gait ability compared with an intramedullary tumor only. Earlier surgery with intraoperative spinal cord monitoring is recommended for total resection and good surgical outcome especially for an IE tumor compared with an intramedullary tumor.

Abstract
INTRODUCTION Grade II and III intramedullary ependymomas [IME] are circumscribed with a plane of cleavage that should facilitate high gross total resection rates (GTR). Gross total resection of grade II/III IME is superior to subtotal resection (STR) and radiotherapy (RTx) for progression-free and overall survival. We sought to compare our GTR with other series that have utilised standard intraoperative monitoring techniques and we explored factors that may influence rates of resection. MATERIALS AND METHODS Database search and retrospective chart and radiological review of all grade II or III spinal ependymomas over a 10-year period from the senior authors practice. Comprehensive PubMed search to identify similar series that identified histology, McCormick Function scores (MCC) preoperatively and post-operatively, surgical strategy and use of intraoperative monitoring. Standard statistical analysis was performed. RESULTS Seventeen patients were identified: 16 grade II and one grade 3. GTR was 94.12%. Factors that correlated with a decline in MCC were longitudinal extension of the tumour (p = 0.0238) and presentation with motor signs and symptoms (p = 0.0223). There was no statistical difference between preoperative factors that influence post-operative outcomes in the current study when compared with other published series. There was no statistical difference between preoperative and postoperative MCC scores between our series and other published series. DISCUSSION The current series with a GTR of 94.12% compares favourably with other published series with GTRs of 55.8-84% with no significant difference in functional outcomes. Series with low GTRs should examine their operative strategy or false-positive alarm rates which may lead to higher STRs. This series should be viewed as a unique opportunity to benchmark GTRs of circumscribed intramedullary tumours.

Abstract
Abstract
BACKGROUND AND IMPORTANCE: Pilocytic astrocytoma (PA) is among the most common of the central nervous system gliomas in the pediatric population; however, it is uncommon in adults. PAs of the spinal cord in adults are even rarer, with only a few cases found in the literature. We report here the first case in the literature of multifocal intradural extramedullary spinal cord PAs in an adult.
CLINICAL PRESENTATION: Our patient is a 56-yr-old female who presented with loss of balance and an ataxic gait. Multiple extramedullary spinal cord tumors were identified intraoperatively, the lesions completely resected, and all diagnosed as PAs.
CONCLUSION: This case illustrates a unique instance of multifocal intradural extramedullary spinal cord PAs in an adult with no previous history of PA during childhood, no known familial syndromes, and no brain involvement.

Abstract
OBJECTIVE Surgical excision is the mainstay treatment for resectable low-grade intramedullary spinal cord tumors (IMSCTs) in the pediatric age group. Chemotherapy and radiation treatments are generally reserved for progressive or recurrent disease. Given the indolent nature of low-grade tumors and the potential side effects of these approaches, their long-term treatment benefits are unclear. The aim of the study was to determine long-term disease outcomes and the therapeutic roles of surgery and adjuvant therapies in pediatric patients with low-grade IMSCTs over an extended follow-up period. METHODS Case records for all pediatric patients (< 21 years of age) with a histopathological diagnosis of low-grade IMSCT were selected over a period from January 1975 to January 2010. Outcome variables including McCormick functional grade, overall survival (OS), and progression-free survival (PFS) were analyzed with respect to demographic and treatment variables. RESULTS Case records of 37 patients with low-grade IMSCTs were identified, with a mean follow-up duration of 12.3 ± 1.4 years (range 0.5-37.2 years). Low-grade astrocytomas were the most prevalent histological subtype (n = 22, 59%). Gross-total resection (GTR) was achieved in 38% of patients (n = 14). Fusion surgery was required in 62% of patients with pre- or postoperative deformity (10 of 16). On presentation, functional improvement was observed in 87% and 46% of patients in McCormick Grades I and II, respectively, and in 100%, 100%, and 75% in Grades III, IV, and V, respectively. Kaplan-Meier PFS rates were 63% at 5 years, 57% at 10 years, and 44% at 20 years. OS rates were 92% at 5 years, 80% at 10 years, and 65% at 20 years. On multivariate analysis, shunt placement (hazard ratio [HR] 0.33, p = 0.01) correlated with disease progression. There was a trend toward improved 5-year PFS in patients who received adjuvant chemotherapy and radiation therapy (RT; 55%) compared with those who did not (36%). Patients who underwent subtotal resection (STR) were most likely to undergo adjuvant therapy (HR 7.86, p = 0.02). CONCLUSIONS This extended follow-up duration in patients with low-grade IMSCTs beyond the first decade indicates favorable long-term OS up to 65% at 20 years. GTR improved PFS and was well tolerated with sustained functional improvement in the majority of patients. Adjuvant chemotherapy and RT improved PFS in patients who underwent STR. These results emphasize the role of resection as the primary treatment approach, with adjuvant therapy reserved for patients at risk for disease progression and those with residual tumor burden.

Abstract
The differential diagnoses for spinal cord lesions include spinal tumors and inflammatory processes. The distinction between these pathologies can be difficult if solely based on imaging. We report for the first time to our knowledge a case of idiopathic transverse myelitis (ITM) mimicking a discrete cervical spinal lesion in a 66-year-old man who presented with gait instability and neck pain. The patient's symptoms failed to resolve after an initial course of steroid therapy. Surgical biopsy confirmed the diagnosis of ITM. Subsequent treatment with dexamethasone resulted in complete resolution of the symptoms as well as the intramedullary enhancement. ITM is most common in the cervical and thoracic spine, spanning 3-4 spinal segments. It usually occupies more than 50% of the cross-sectional area of the spinal cord and tends to be central, uniform, and symmetric. It exhibits patchy and peripheral contrast enhancement. These criteria are useful guidelines that help distinguish ITM from neoplastic spinal lesions. A decision to perform biopsy must take into consideration the patient's clinical symptoms, the rate of progression of neurological deficits, and the imaging characteristics of the lesion. Surgical biopsy for questionable lesions should be reserved for patients with progressive neurological deficits refractory to empirical medical therapy.

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.

Molecular and clinical prognostic factors for favorable outcome following surgical resection of adult intramedullary spinal cord astrocytomas. Clin Neurol Neurosurg 2016; 144:82-7. [PMID: 26999530 DOI: 10.1016/j.clineuro.2016.03.009] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Revised: 03/10/2016] [Accepted: 03/12/2016] [Indexed: 11/25/2022]
Abstract
OBJECTIVE Intramedullary spinal cord astrocytomas are uncommon but important entities. Aggressive surgical resection is believed to be critical to prevent subsequent neurological deterioration; however, the prognostic significance of numerous patient and molecular variables remains unclear. We sought to investigate the clinical and molecular factors associated with outcomes following surgical resection of adult spinal cord astrocytomas. METHODS A consecutive retrospective chart review of all patients who underwent intramedullary spinal cord astrocytoma resection at a single tertiary-care institution between January 1996 and December 2011 was conducted. Molecular data collected included p53 mutation status, proliferative activity (Ki-67), 1p/19q chromosome loss, and EGFR amplification. Multivariable logistic and Cox proportional hazards regression were used to identify variable associated with postoperative outcomes. RESULTS Among 13 patients undergoing surgical resection followed for a median of 54 months, 54% experienced improvement in neurological status, while 15% remained unchanged and 31% deteriorated. Following resection, the 5-year local control (LC), progression-free survival (PFS), and overall survival (OS) rates were 83%, 63%, and 83%. Median PFS time was found to be 5.6 years. Multivariable regression revealed limited characteristics associated with postoperative outcomes, though no molecular characteristics were found to be prognostic. Older age at surgery predicted decreased probability of PFS (HR 0.91, 95% CI 0.81-0.99, p=0.03) and trended towards predicting lack of neurological improvement (OR 0.94, 95% CI 0.83-1.02, p=0.21) and decreased OS (HR 0.93, 95% CI 0.81, 1.03, p=0.15). Preoperative motor symptoms (OR 0.12, 95% CI <0.01-1.91, p=0.14) and adjuvant chemotherapy (OR 0.07, 95% CI <0.01-1.82, p=0.12) also trended towards predicting lack of neurological improvement. CONCLUSION Age was the only patient variable found to have a statistically significant association with profession-free survival and no other factors were significantly associated with postoperative outcomes. These findings were limited by a relatively small sample size; thus, future studies with increased power investigating the prognostic effects of molecular characteristics could provide further clarity in identifying patients most likely to benefit from surgical resection.

Abstract
Study Design A retrospective study. Purpose The purpose of this study was to obtain useful information for establishing the guidelines for treating high-grade spinal cord gliomas. Overview of Literature The optimal management of high-grade spinal cord gliomas remains controversial. We report the outcomes of the surgical management of 14 high-grade spinal glioma. Methods We analyzed the outcomes of 14 patients with high-grade spinal cord gliomas who were surgically treated between 1989 and 2012. Survival was charted with the Kaplan-Meier plots and comparisons were made with the log-rank test. Results None of the patients with high-grade spinal cord gliomas underwent total resection. Subtotal resection was performed in two patients, partial resection was performed in nine patients, and open biopsy was performed in three patients. All patients underwent postoperative radiotherapy and six patients further underwent radiation cordotomy. The median survival time for patients with high-grade spinal cord gliomas was 15 months, with a 5-year survival rate of 22.2%. The median survival time for patients with World Health Organization grade III tumors was 25.5 months, whereas the median survival time for patients with glioblastoma multiforme was 12.5 months. Both univariate and multivariate Cox proportional hazards models demonstrated a significant effect only in the group that did not include cervical cord lesion as a factor associated with survival (p=0.04 and 0.03). Conclusions The surgical outcome of patients diagnosed with high-grade spinal cord gliomas remains poor. Notably, only the model which excluded cervical cord lesions as a factor significantly predicted survival.

Abstract
Hemangioblastomas are benign, highly vascularized intramedullary lesions that may also extend into the intradural space. Surgery represents the standard therapy, with the goal of obtaining complete resection even at the risk of neurological morbidity. MRI is the gold standard for diagnosis and assessment of intramedullary tumors. Nevertheless, sometimes MRI may not accurately differentiate between different types of intramedullary tumors, in particular if they are associated with syringes or intra- and peritumoral cysts. This could subsequently affect surgical strategies. Intraoperative ultrasound (ioUS) has become in the last few years a very useful tool for use during neurosurgical procedures. Various ioUS modalities such as B-mode and Doppler have been applied during neurosurgical procedures. On the other hand, the use of contrast-enhanced ultrasound (CEUS) is not yet well defined and standardized in this field. We report a case of a young patient harboring a cervicothoracic intramedullary tumor, for which the preoperative neuroradiologi-cal diagnosis was in favor of a diffuse astrocytoma with nodular components whereas ioUS demonstrated 3 distinct intramedullary nodules. CEUS showed highly vascularized lesions, compatible with hemangioblastomas. These findings, particularly those obtained with CEUS, allowed better definition of the lesions for diagnosis, enhanced understanding of the physiopathological aspects, and permitted the localization of all 3 nodules, thus limiting spinal cord manipulation and allowing complete resection of the lesions, with an uneventful postoperative neurological course.
To the best of our knowledge, this is the first report of the use of intraoperative CEUS in a case of intramedullary hemangioblastoma.

Abstract
We report our institution's experience with adult patients who underwent surgery for intramedullary spinal cord glioblastoma. Spine involvement of glioblastoma is rare, representing 7.5% of all intramedullary gliomas and 1-3% of all spinal cord tumors. We performed a retrospective review of five male patients with intramedullary spinal cord glioblastoma who underwent surgical resection from 1990 to 2014. Demographic, operative, and postoperative factors were recorded. The median age at treatment was 31 years (range: 18-61) and all men presented with motor or sensory dysfunction. Two had prior surgical resection of an intramedullary World Health Organization Grade III anaplastic astrocytoma lesion with adjuvant chemoradiation. All tumors were present in the cervical (n=2; 40%) or thoracic (n=3; 60%) spine, spanning a median of three levels (range: 2-4). Gross total resection was achieved in three men (60%), and there were no intraoperative mortalities or complications. Although one had improvement in his neurological status postoperatively, all five men died with a median time to death of 20 months (range: 2-31). Adult intramedullary spinal cord glioblastoma is rare, and despite aggressive treatment, prognosis is poor, with a median survival in our series of only 20 months. New treatment strategies are necessary to improve survival in this patient population.

Abstract
Objective Spinal intramedullary tuberculoma (SIMT) is rare, accounting for 2/100,000 cases of tuberculosis and only 0.2% of all cases of central nervous system(CNS) tuberculosis. We share our experiences of 11 cases of this entity for improving diagnosis and conceptualize the management of this rare disease. Methods The clinical profile, radiological data and management of 11 cases of SIMT which were managed either conservatively or by surgical intervention during last 27 years (1987-2014) were analysed. Results Male:female ratio was 1.75:1. Five cases had associated pulmonary Koch's. Most common site was thoracic cord. Two cases had concurrent multiple intracranial tuberculoma. Most common presentation was paraparesis. X-ray myelography was performed in two patients in the initial period of study suggesting intramedullary pathology. In the subsequent nine cases who had magnetic resonance imaging (MRI), seven showed typical "target sign" and conglomerate ring lesion. Out of 8 surgically managed patients, 6 cases improved rapidly and in 2 patients gradual improvement was seen in follow-up. Most common indication of surgical excision was rapid neurological deterioration followed by diagnosis in doubt. Histopathology confirmed tuberculous etiology of the intramedullary lesion in all. Clinical and radiological improvement was seen in all 3 conservatively managed patients in follow-up. Conclusion MRI findings of SIMT were specific and proven histologically correct. Surgical intervention may be indicated if there is no response to chemotherapy, the diagnosis is in doubt, or there is a rapid deterioration in neurological function because surgical outcome is good in these circumstances.

Abstract
Intraspinal angiomatous meningiomas (AMs) are rare lesions, and no case series have been reported. We retrospectively reviewed the data of 12 patients with intraspinal AMs. All patients underwent magnetic resonance imaging (MRI) of the spine. Computed tomography angiography was performed for three cases with cervical lesion. The series included six females and six males with a mean age of 49.6 years. Five tumors were located in the cervical, one in the cervicothoracic, five in the thoracic, and one in the thoracolumbar spine. The most common symptom was motor deficits and the mean duration of symptoms was 18 months. All patients were treated surgically with gross total resection (GTR) (Simpson grade I and II resection). No patients underwent embolization. After surgery immediately, the neurological function was improved in five patients, remained stable in six patients, and was deteriorated in one patient. During an average follow up of 78.6 months, 11 patients experienced an improvement in the neurological function and one patient maintained preoperative status. No tumor recurrence was observed on MRI. Compared to conventional meningiomas, AMs have no special clinical and radiological features. The accurate diagnosis depends on pathology. Timely GTR (en bloc resection) is the best treatment and embolization is not necessary for most patients. Radiotherapy is not recommended after GTR (Simpson grade I and II resection), and the risk of tumor recurrence is low.

Abstract
Abstract
BACKGROUND:
Surgical outcomes for intramedullary spinal cord tumors are affected by many variables including tumor histology and preoperative neurological function.
OBJECTIVE:
To analyze the impact of tumor histology on neurological outcome in primary intramedullary spinal cord tumors.
METHODS:
A retrospective review of 102 consecutive patients with intramedullary spinal cord tumors treated at a single institution between January 1998 and March 2009.
RESULTS:
Ependymomas were the most common tumors with 55 (53.9%), followed by 21 astrocytomas (20.6%), 12 hemangioblastomas (11.8%), and 14 miscellaneous tumors (13.7%). Gross total resection was achieved in 50 ependymomas (90.9%), 3 astrocytomas (14.3%), 11 hemangioblastomas (91.7%), and 12 miscellaneous tumors (85.7%). At a mean follow-up of 41.8 months (range, 1-132 months), we observed recurrences in 4 ependymoma cases (7.3%), 10 astrocytoma cases (47.6%), 1 miscellaneous tumor case (7.1%), and no recurrence in hemangioblastoma cases. When analyzed by tumor location, there was no difference in neurological outcomes (P = .66). At the time of their last follow-up visit, 11 patients (20%) with an ependymoma improved, 38 (69%) remained the same, and 6 (10.9%) worsened. In patients with an astrocytoma, 1 (4.8%) improved, 10 (47.6%) remained the same, and 10 (47.6%) worsened. One patient (8.3%) with a hemangioblastoma improved and 11 (91.7%) remained the same. No patient with a hemangioblastoma worsened. In the miscellaneous tumor group, 2 (14.3%) improved, 10 (71.4%) remained the same, and 2 (14.3%) worsened. Preoperative neurological status (P = .02), tumor histology (P = .005), and extent of resection (P < .0001) were all predictive of functional neurological outcomes.
CONCLUSION:
Tumor histology is the most important predictor of neurological outcome after surgical resection because it predicts resectability and recurrence.

Abstract
PURPOSE The aim of this study was to discuss the clinical manifestations, radiological features, treatment, and long-term outcomes of intraspinal ependymomas (Word Health Organization grade II) in pediatric patients. METHODS The data of 15 pediatric patients who underwent microsurgery for intraspinal grade II ependymomas were retrospectively reviewed. Pre- and postoperative magnetic resonance imaging was performed in all patients. The diagnosis of grade II ependymomas was based on pathology. All the follow-up data were obtained during office visits. RESULTS There were ten males and five females, with a mean age of 13.7 ± 3.4 years. Four tumors were located in the cervical cord, six in the cervicothoracic cord, four in the thoracic cord, and one in the conus-cauda region, respectively. The most common symptom was motor deficits. Gross total resection (GTR) of the tumor was achieved in 12 cases, and subtotal resection (STR) was achieved in three cases. Regrowth of the residual tumor was observed in two STR cases during a mean follow-up period of 44.8 months. STR was performed again in one case due to clinical progression. At the last follow-up, 12 patients experienced an improvement in the neurological function and three patients maintained their preoperative status. CONCLUSIONS Pediatric intraspinal grade II ependymomas are amenable to surgical resection before neurological deficits deteriorate. GTR is the best treatment of choice, and the outcome is favorable. Due to uncertain therapeutic efficacy and possible radiation-induced toxicity, postoperative radiotherapy should be considered carefully for cases of STR.

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
OBJECT Radical resection is recommended as the first-line treatment for pediatric intramedullary spinal cord tumors (IMSCTs), but it is associated with morbidity, including risk of neurological decline and development of postoperative spinal deformity. The authors report long-term data on clinical and treatment determinants affecting disease survival and neurological outcomes. METHODS Case records for pediatric patients (< 21 years of age at presentation) who underwent surgery for IMSCTs at the authors' institution between January 1975 and January 2010 were analyzed. The patients' demographic and clinical characteristics (including baseline neurological condition), the treatment they received, and their disease course were reviewed. Long-term disease survival and functional outcome measures were analyzed. RESULTS A total of 55 patients (30 male and 25 female) were identified. The mean duration of follow-up (± SEM) was 11.4 ± 1.3 years (median 9.3 years, range 0.2-37.2 years). Astrocytomas were the most common tumor subtype (29 tumors [53%]). Gross-total resection (GTR) was achieved in 21 (38%) of the 55 patients. At the most recent follow-up, 30 patients (55%) showed neurological improvement, 17 (31%) showed neurological decline, and 8 (15%) remained neurologically stable. Patients presenting with McCormick Grade I were more likely to show functional improvement by final follow-up (p = 0.01) than patients who presented with Grades II-V. Kaplan-Meier actuarial tumor progression-free survival rates at 5, 10, and 20 years were 61%, 54%, and 44%, respectively; the overall survival rates were 85% at 5 years, 74% at 10 years, and 64% at 20 years. On multivariate analysis, GTR (p = 0.04) and tumor histological grade (p = 0.02) were predictive of long-term survival; GTR was also associated with improved 5-year progression-free survival (p = 0.01). CONCLUSIONS The prognosis for pediatric IMSCTs is favorable with sustained functional improvement expected in a significant proportion of patients on long-term follow-up. Long-term survival at 10 years (75%) and 20 years (64%) is associated with aggressive resection. Gross-total resection was also associated with improved 5-year progression-free survival (86%). Hence, the treatment benefits of GTR are sustained on extended follow-up.

Abstract
STUDY DESIGN Retrospective cohort analysis. OBJECTIVE To examine the effect of resection on survival and neurological outcome in a modern cohort of patients with spinal cord astrocytomas and identify prognostic factors for survival. SUMMARY OF BACKGROUND DATA There are currently no clear treatment guidelines for the management of spinal cord astrocytomas. Additionally there is no conclusive evidence for the surgical resection of these tumors, with some studies even demonstrating worse survival with surgery. However, most studies have examined patients treated prior to the routine use of magnetic resonance imaging and advanced microsurgical techniques. METHODS We performed a retrospective review of 46 consecutive patients with spinal cord astrocytomas treated at our institution from 1992 to 2012. Univariate and multivariate analyses were used to identify variables associated with survival. RESULTS The majority of patients (67.4%) underwent surgical resection, with the remaining only receiving biopsy. Of those who underwent resection, only 12.5% of patients underwent gross total resection, all of whom had low-grade astrocytomas. Of all patients, 30.7% worsened compared with their preoperative baseline. The occurrence of worsening increased with high tumor grade (52.9% vs. 27.6%, P = 0.086) and an increased extent of resection (66.7% vs. 18.8%, P = 0.0069). Resection did not provide a survival benefit compared with biopsy alone (P = 0.53). Multivariate analysis revealed high-grade histology (hazard ratio, 11.3; 95% confidence interval, 2.41-53.2; P = 0.0021), tumor dissemination (hazard ratio, 4.24; 95% confidence interval, 1.22-14.8; P = 0.023), and an increasing number of tumor involved levels (hazard ratio, 1.31; 95% confidence interval, 0.99-1.74; P = 0.058) to be associated with worse survival. CONCLUSION As surgical intervention is associated with a higher rate of neurological complications and lacks a clear benefit, the resection of spinal cord astrocytomas should be reserved for select cases and should be used sparingly.

Abstract
OBJECT Ependymomas are a common type of CNS tumor in children, although only 13% originate from the spinal cord. Aside from location and extent of resection, the factors that affect outcome are not well understood. METHODS The authors performed a search of an institutional neuropathology database to identify all patients with spinal cord ependymomas treated over the past 20 years. Data on patient age, sex, clinical presentation, symptom duration, tumor location, extent of resection, use of radiation therapy, surgical complications, presence of tumor recurrence, duration of follow-up, and residual symptoms were collected. Pediatric patients were defined as those 21 years of age or younger at diagnosis. The extent of resection was defined by the findings of the postoperative MR images. RESULTS A total of 24 pediatric patients with spinal cord ependymomas were identified with the following pathological subtypes: 14 classic (Grade II), 8 myxopapillary (Grade I), and 2 anaplastic (Grade III) ependymomas. Both anaplastic ependymomas originated in the intracranial compartment and spread to the spinal cord at recurrence. The mean follow-up duration for patients with classic and myxopapillary ependymomas was 63 and 45 months, respectively. Seven patients with classic ependymomas underwent gross-total resection (GTR), while 4 received subtotal resection (STR), 2 received STR as well as radiation therapy, and 1 received radiation therapy alone. All but 1 patient with myxopapillary ependymomas underwent GTR. Three recurrences were identified in the Grade II group at 45, 48, and 228 months. A single recurrence was identified in the Grade I group at 71 months. The mean progression-free survival (PFS) was 58 months in the Grade II group and 45 months in the Grade I group. CONCLUSIONS Extent of resection is an important prognostic factor in all pediatric spinal cord ependymomas, particularly Grade II ependymomas. These data suggest that achieving GTR is more difficult in the upper spinal cord, making tumor location another important factor. Although classified as Grade I lesions, myxopapillary ependymomas had similar outcomes when compared with classic (Grade II) ependymomas, particularly with respect to PFS. Long-term complications or new neurological deficits were rare. Among patients with long-term follow-up, those who underwent GTR had a recurrence rate of 20% compared with 40% among those with STR or biopsy only, suggesting that extent of resection is perhaps a more important prognostic factor than histological grade in predicting PFS, which has been suggested by other data in the literature. Given the relative paucity of these lesions, collaborative multiinstitutional studies are needed, and such efforts should also focus on molecular and genetic analysis to refine the current classification system.

Abstract
OBJECT Presently, the best available treatment for intramedullary spinal cord tumors (IMSCTs) in children is microsurgery with the objective of maximal tumor removal and minimal neurological morbidity. The latter has become manageable with the development and standard use of intraoperative neurophysiological monitoring. Traditionally, the perioperative neurological evaluation is based on surgical or spinal cord injury scores focusing on sensorimotor function. Little is known about the quality of life after such operations; therefore, this study was designed to investigate the impact of surgery for IMSCTs on the quality of life in children. METHODS Twelve consecutive pediatric patients treated for IMSCT were included in this retrospective fixed cohort study. A multidimensional questionnaire-based quality of life instrument, the Pediatric Quality of Life Questionnaire version 4 (PedsQL 4.0), was chosen to analyze follow-up data. This validated instrument particularly allows for a comparison between a patient cohort and a healthy pediatric sample population. RESULTS Of 11 mailed questionnaires (1 patient had died of progressive disease), 10 were returned, resulting in a response rate of 91%. There were 8 low-grade lesions (5 pilocytic astrocytomas, 1 ganglioglioma, 1 hemangioblastoma, and 1 cavernoma) and 4 high-grade lesions (2 anaplastic gangliogliomas, 1 glioblastoma, and 1 glioneuronal tumor). The mean age at diagnosis was 7.5 years, the mean follow-up was 4.2 years, and 83% of the patients were male. Total resection was achieved in 5 patients and subtotal resection in 7. Four patients had undergone 2 or more resections. The 4 patients with high-grade tumors and 2 with incompletely resected low-grade tumors underwent adjuvant treatment (2 chemotherapy and 4 both radiotherapy and chemotherapy). The mean modified McCormick Scale score at the time of diagnosis was 1.7; at the time of follow-up, 1.5. The mean PedsQL 4.0 total score in the low-grade group was 78.5; in the high-grade group, 82.6. There was no significant difference in PedsQL 4.0 scores between the patient cohort and the normal population. CONCLUSIONS In a small cohort of children who had undergone surgery for IMSCTs with a mean follow-up of 4.2 years, quality of life scores according to the PedsQL 4.0 instrument were not different from those in a normal sample population.

Abstract
OBJECT Intradural cauda equina and conus medullaris tumors (CECMTs) are rare. Only a few large clinical series exist to date. Therefore, clinical symptoms, surgical complications, and outcomes are poorly understood. The aim of the present study was to evaluate outcome after surgery of CECMTs and to identify the factors associated with a worse clinical prognosis based on the results of a series with sufficiently high number of cases. METHODS All cases of intradural CECMTs treated surgically at the authors' department between March 2006 and May 2012 were retrospectively evaluated. Arachnoid cysts and multifocal tumors were excluded. Sixty-eight adult patients met the inclusion criteria (35 female and 33 male patients; median age 56 years). Follow-up data were available for 72% (n = 49) in a median period of 9 months. RESULTS Overall, 18 tumors were located intramedullary and 50 extramedullary. The majority were nerve sheath tumors (n = 27), ependymomas (n = 17), and meningiomas (n = 9). The most common preoperative symptom was pain. The rate of new transient postoperative impairment was 18% (n = 12), and new permanent deficits were observed in only 6% (n = 4). Overall neurological improvement was achieved in 62%. The reversibility of preoperative symptoms was related to the interval between the time of symptom onset and the time of surgery and to the presence of preoperative neurological deficits. Surgery of ependymoma and carcinoma metastases was associated with a higher rate of morbidity. CONCLUSIONS Intradural CECMTs present as a group of tumors with varying histological features and clinical symptoms. Symptomatic manifestation is usually unspecific, mimicking degenerative lumbar spine syndromes. Despite a significant risk of transient deterioration, early surgery is advisable because more than 94% of patients maintain at least their preoperative status and more than 60% improve during follow-up. The reversibility of preoperative symptoms is related to the duration between symptom onset and surgery and to the presence of preoperative neurological deficits. The prognosis for recovery from cauda equina or conus medullaris syndrome is less favorable than for other deficits. Surgery of ependymoma is associated with a higher morbidity rate than other benign entities.

Abstract
UNLABELLED Extramedullary spinal cord tumors (ESCTs) are relatively rare neoplasms requiring surgical treatment. This paper presents a study of outcomes in patients with ESCTs treated at Irkutsk region hospitals with different facilities. AIM To identify factors affecting the outcome of surgical treatment of ESCTs. MATERIAL AND METHODS The disease stage before surgery was evaluated according to the I.Ya. Razdol'skiy and McCormick classifications. Features and extension of the approach, the extent of blood loss, surgery duration, and the equipment used were analyzed. Treatment outcomes were assessed according to the MacNub and McCormick neurological outcome scales. RESULTS ESCTs were removed totally in 84 (95%) patients and subtotally in 4 (5%). Tumor recurrence was detected in 8 patients. No deaths were observed. No correlation was found between the treatment outcome, according to the McCormick scale, and factors such as gender, tumor location, histological type, tumor grade, disease duration, and type of a surgical approach and the equipment used. Factors having medium and high correlations with the disease outcome are a neurological disease phase and an initial neurological deficit: sensory deficit, r=0.32; motor deficit, r=0.33; pelvic disturbances, r=0.35; McCormick grade before surgery, r=0.74; disease phase r=0.41 (p<0.05). CONCLUSION The disease phase is the most significant factor affecting the outcome of surgical treatment in patients with ESCTs. Despite this, important aspects of surgical treatment of ESCT include the approach that is adequate to the tumor size and localization, as well as combination of different surgical techniques.
