Abstract
Myxopapillary ependymomas (MPEs) are rare spinal cord tumors with low rates of metastasis outside of the neuraxis. Gross total resection of MPEs can significantly improve progression-free survival; however, adjunctive treatment remains unstandardized. A 29-year-old female with a history of spina bifida occulta surgical correction and lower back pain presented with dyspnea and tachycardia. A large pulmonary artery mass was discovered consistent with pulmonary thromboembolism. It was subsequently determined to be an intravascular metastasis secondary to sacral MPE. Standardization of MPE treatment and clinical suspicion of spinal neoplasm in the setting of chronic back pain with undetermined origin are of value.

Abstract
PURPOSE Myxopapillary ependymoma (MPE) was classified as grade 2 tumor in the 2021 World Health Organization central nervous system classification because of its high recurrence probability. This study aimed to investigate predictive factors and management of tumor recurrence. METHODS Seventy-two patients with spinal MPE underwent initial surgical treatment at our hospital between 2011 and 2021. Kaplan-Meier curves and Cox regression were used to analyze the correlation between clinical variables and progression-free survival (PFS). RESULTS The median age at diagnosis was 33.5 years (range 8-60 years). Twenty-one patients (29.2%) had preoperative spinal drop metastases. Gross total resection (GTR) was performed in 37 patients (51.4%). The median follow-up was 7.2 years, and the follow-up rate was 88.9% (64 of 72 cases). Twelve of the 64 patients (18.9%) relapsed, and preoperative drop metastasis occurred in 7 patients (58.3%). The estimated 5-year and 10-year PFS rates were 82% and 77%, respectively. Univariate analysis showed that GTR was associated with improved PFS (hazard ratio [HR] 0.149, p = 0.014), while preoperative drop metastasis (HR 3.648, p = 0.027) and tumor involvement sacrococcygeal region (HR 7.563, p = 0.003) were associated with tumor recurrence. Adjuvant radiotherapy (RT) was significantly associated with improved PFS in patients with preoperative drop metastasis (p = 0.039). CONCLUSION Complete surgical resection under the premise of protecting neurological function is an important factor in reducing spinal MPE recurrence. Adjuvant RT is recommended when the tumor invades the capsule with preoperative drop metastasis or adhesion to the nerve and cannot reach GTR.

Abstract
We report a case of primary intraabdominal ependymoma arising in the retropubic space of a male patient. An incidental intraabdominal mass was discovered in a 51-year-old man. Radiological studies revealed a 10 cm, solid and cystic tumor located in the Retzius fossa. Microscopically, the lesion was characterized by multiple cellular nodules composed of bland small cells forming true and pseudorosettes. No nuclear atypia, necrosis or increased mitotic activity was present. Neoplastic cells positive for AE1/3 and Cam5.2, and expressed patchy GFAP, and paranuclear dot-like to microvesicular EMA and D2-40, while S100, synaptophysin, PAX8, TLE1, WT1, inhibin, calretinin, Melan-A, and HMB45 were negative. Electron microscopy findings supported the diagnosis: 1) Frequent intracytoplasmic vacuoles with short and redundant microvilli and few cilia 2) lung intercellular junctions. The patient is alive with no evidence of disease for 4 years. Pathologists should be aware that rare extraneural ependymomas may occur in the Retzius space, even in a male patient. This entity should be kept in mind especially when the differential diagnosis is metastatic carcinoma with an unusual morphology and immune profile.

Abstract
Ependymomas are tumors located in the central nervous system, mostly in the brain and spinal cord. This tumor is rarely seen as a primary mediastinal location. The aim of this study is to discuss this rare pathology in the clinical course of an unusual case. A 47-year-old female patient was referred to our clinic with the complaint of back and shoulder pain, via VATS posterior mediastinum located paravertebral mass excision was performed. The pathology reported as ependymoma. Two years later, CT scans of the routine control showed the well-defined mass in anterior mediastinum. The SUVmax of the lesion was measured as 9.3 at PET-CT. The lesion in the anterior mediastinum was excised by partial sternotomy. The pathology result was the same as the prior operation: Ependymoma. As our case, in these kinds of tumors meticulous follow-up of the patients is important for the detection and treatment of recurrent localization and distant metastases.

Abstract
OBJECTIVE Myxopapillary ependymomas (MPEs) in children are rarely reported low-grade glial tumors; however, MPEs sometimes possess malignant characteristics such as spinal seeding/drop metastasis (SSM). We aimed to present 3 pediatric MPE cases that experienced SSM at 2 neurosurgical centers. MATERIALS AND METHODS We retrospectively reviewed the medical records of 38 primary spinal MPE cases who underwent surgery at 2 neurosurgical centers spanning 16 years, from 2004 to 2019. All pediatric cases (patient age <18 years) who were diagnosed with MPE and re-presented with SSM were selected as the core sample for this study. Relevant literature was briefly reviewed. RESULTS Three pediatric MPE cases (2 females and 1 male) experienced SSM. The mean age at first presentation was 12.0 ± 1.0 years. The mean preoperative course was 2.9 ± 1.2 months. The predominant location was the lumbar spine in 2 tumors (both originated from terminal filum [TF]). Two tumors were located intradural intramedullary. Gross-total resection was achieved in 2 patients. No patient had neurofibromatosis type 2. No adjuvant treatment was given after the first surgery. The mean period between the first diagnosis and diagnosis of SSM was 44.0 ± 31.5 months. The location of SSM in all patients was the sacral spine (1 patient experienced distant metastasis in her brain besides her sacral metastasis). The mean follow-up was 68.3 ± 53.7 months. CONCLUSIONS We found a statistically significant relationship between SSM in pediatric MPEs and the intramedullary location, TF origin, and number of affected segments. Close clinical and radiological follow-up is essential for pediatric MPE patients.

Abstract
BACKGROUND Myxopapillary ependymoma (MPE) is a rarely reported lesion of the spinal cord in the pediatric population. Based on their low mitotic index and slow-growth, MPEs are classified as low-grade glial tumors. However, MPEs have malignant characteristics, such as distant neural axis and extraneural axis dissemination. We present the long-term surgical resection outcomes of 5 consecutive pediatric MPE cases and the results of a literature search for reported cases of pediatric spinal MPE. METHODS We retrospectively reviewed the medical records of 38 primary spinal MPE cases who underwent surgery at 2 neurosurgical centers over a 16-year period from January 2004 to January 2019. All pediatric cases (age <18 years; n = 5) who were diagnosed with MPE composed the core sample for this study. RESULTS This series comprised 5 patients (3 females and 2 males), with a mean age at first presentation of 13.6 ± 2.3 years. The mean preoperative course was 8.2 ± 9.3 months. The predominant location was the lumbar spine, for 4 tumors. Gross total resection (GTR) was achieved in 4 patients. All patients were diagnosed histopathologically as MPE, World Health Organization grade I. No adjuvant treatment was provided after the first surgery. Three patients experienced spinal drop metastasis. The mean interval between the first diagnosis and diagnosis of neural dissemination was 44.0 ± 31.5 months. The location of neural dissemination in all patients was the sacral spine; 1 patient experienced distant metastasis in the brain along with her sacral metastasis. The mean duration of follow-up was 75.0 ± 37.6 months. CONCLUSIONS Even with GTR, pediatric MPE has a high propensity for neural axis dissemination. We recommend close clinical and radiologic follow-up for pediatric patients with MPE.

Abstract
Myxopapillary ependymomas are a slow-growing, grade I type glial tumor in the lumbosacral region. More rarely, they can present as extradural, subcutaneous sacrococcygeal, or perisacral masses, and it is under these circumstances that they are more likely to spread. Here, we report the presentation of a sacrococcygeal mass in patient that was initially resected confirming extradural myxopapillary ependymoma. At initial resection, multiple small pulmonary nodules were detected. This mass recurred 2 years later at the resection site with an interval increase in the previously imaged pulmonary nodules. Resection of both the post-sacral mass and largest lung metastasis confirmed recurrent myxopapillary ependymoma with oligometastatic spread. Because these tumors are rare, with extradural presentation being even more infrequent, to this date there are no definitive therapeutic guidelines for initial treatment and continued surveillance. For myxopapillary ependymoma, current standard of care is first-line maximal surgical resection with or without postoperative radiotherapy depending on the extent of disease and extent of resection. However, there remains insufficient evidence on the role of radiotherapy to oligometastatic foci in providing any further survival benefit or extending time to recurrence. Thus, prospective studies assessing the role of upfront treatment of oligometastases with local resection and adjuvant radiotherapy are needed for improved understanding of extradural myxopapillary ependymoma.

Abstract
Background The aim of this study was to assess the clinical and radiological outcomes of surgical treatment for primary spinal ependymoma in children. Material/Methods Medical records of 46 primary spinal ependymoma patients who underwent surgery in BRSHH hospital during a 12-year period from 2004 to 2015 were retrospectively reviewed. All pediatric patients (patient age <18 years) were selected as the core sample used for this study. Results This series included 1 female and 2 male patients between the ages of 9 and 17 years with mean age 13.3±3.9 years. The mean preoperative course was 9.1±10.5 months. The most common location was the lumbar spinal cord (n=2). The most common presenting symptoms was lower-limb weakness and numbness. Two tumors were located intradural-intramedullary and 1 was located intradural-extramedullary. Gross-total resection (GTR) was achieved in 2 patients, and a near-total resection was performed in 1 patient. No adjuvant treatment was received. The mean follow-up duration was 51.3±37.6 (17–98) months. No complications were recorded. Functional assessment of all patients by the latest follow-up evaluation showed good progress even though the patient is not fully recovered. At 6.3 years after the first operation, 1 patient presented with drop-seeding metastasis. No patients had neurofibromatosis type 2. Conclusions Laminoplasty and intraoperative neurophysiological monitorization are essential in surgical treatment of pediatric spinal ependymomas. GTR and recovery in pediatric spinal ependymoma are more likely than in adults. Despite the GTR, the risk of drop metastasis remains. Therefore, close clinical and radiological follow-up is recommended.

Abstract
Myxopapillary ependymoma is a benign slow-growing tumour, arising predominantly in the region of the filum terminale. It has been designated histologically as grade I neoplasm according to the 2007 WHO classification. Despite this benign character dissemination and metastasis along the cerebrospinal axis and metastasis to distant sites have occasionally been reported. There have been previously reported cases of drop metastasis from MPE, however in three of these cases the drop metastasis was diagnosed with concurrent primary spinal MPE. There has been only one previously published case of interval drop metastasis in a case of operated spinal MPE in literature. We hereby present the second case of interval drop metastasis in a case of conus MPE, with history of having undergone a subtotal resection and post operative adjuvant radiotherapy prior to second surgery. The patient presented months after the primary surgery with symptoms of cauda equina syndrome attributable to the drop metastasis.

Abstract
Myxopapillary ependymoma (MPE) is an exceedingly rare tumor histology. While surgery is clearly the treatment of choice, controversy exists regarding the role of adjuvant radiotherapy (RT). Using the Surveillence, epidemiology, and end results (SEER) database, we aimed to determine the epidemiology, prognostic factors, and treatment-related outcomes for MPE. A total of 773 cases were found in the SEER database. The incidence in the American population was found to be 1.00 per million person-years. On multivariate analysis, receipt of surgery (HR = 0.14, CI = 0.06-0.35, p < 0.001), receipt of RT (HR = 4.06, CI = 1.87-8.81, p < 0.001), age less than 30 (HR = 0.24, CI = 0.08-0.72, p = 0.01), and Caucasian race (HR = 0.37, CI = 0.13-0.996, p = 0.049) were statistically significant prognostic factors. The mean tumor size among those receiving RT (4.6 cm) was significantly larger than among those not receiving RT (3.2 cm, p = 0.0002). Those who lived in metropolitan areas were more likely to receive RT than those who did not. Given multiple previous studies show that RT improves PFS and the discrepancy in tumor size, selection bias is likely a significant contributor to the apparent negative impact of RT on OS. Regardless, surgery remains the most crucial aspect in the care of patients with MPE.

Abstract
OBJECTIVES The results in earlier studies have described a variable association with age, extent of resection, and radiotherapy (RT) correlating with the survival of myxopapillary ependymomas. The aim of our study is to perform a survival analysis on patient data gathered from a comprehensive review of the literature and determine the influence of these factors on progression-free (PFS) and overall survival (OS). METHODS A PubMed search was performed to select the articles containing information about the critical events (recurrence/death), time to events, and treatment characteristics (extent of resection with or without RT) in the patients with spinal myxopapillary ependymomas. RESULTS A total of 337 patients with information regarding the critical events, time to events, and treatment characteristics was selected for the inclusion. Patients in gross-total resection group had better PFS and OS (P = 0.001, P = 0.000 respectively). The patients in older age group (>35 years) had better PFS (P = 0.008). Overall PFS did not improve if RT was combined with surgery compared with surgery alone; however, the adjuvant RT benefitted the patients age ≤35 years. RT dose >50 Gy had significant influence on the PFS (P = 0.034). CONCLUSION Gross-total resection plays the most important role in improving PFS and OS. Older patients had better PFS; however, the influence of adjuvant RT was significant in younger age groups. A dose of >50 Gy improves the results, but a randomized controlled study is warranted to arrive at a definite conclusion.

Rare Tumors 2014; 6:5404. [PMID: 25002955 PMCID: PMC4083675 DOI: 10.4081/rt.2014.5404] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2014] [Revised: 05/19/2014] [Accepted: 05/27/2014] [Indexed: 11/23/2022] Open
Abstract
Myxopapillary ependymoma (MPE) is a World Health Organization grade I ependymoma that is quite rare and generally thought to be benign. Possible drop metastasis from MPE has been reported three times in the literature; in each case there were cotemporaneous additional MPE lesions. We report the case of a man who had a piecemeal gross total resection of a MPE at L1-L3 followed by adjuvant external beam radiotherapy (EBRT) who presented sixteen months later with a lesion in the thecal sac consistent with drop metastasis. A subtotal resection and adjuvant EBRT were performed. The patient has been disease-free in follow-up 27 months from the second surgery. A review of the literature regarding the treatment for MPE showed that gross total resection is optimal initial management. Several retrospective studies supported the role of adjuvant radiotherapy in enhancing local control and progression-free survival. Chemotherapy has a minimal role in the management of MPE.

Abstract
Extraneural metastases of ependymoma are very rare, and have been reported in the lungs, lymph nodes, pleura, mediastinum, liver, diaphragmatic muscle, and bone. We describe the radiological findings of pathologically proven lung metastases from an anaplastic ependymoma. The tumor which arose in the posterior fossa was first diagnosed in 2007 when first surgical resection was performed outside our institute. Multiple operations were performed after that due to tumor relapse. Multiple lung nodules were discovered incidentally during a VP shunt survey. Biopsy from the lung nodules displayed identical histomorphology to the primary brain tumor.

Abstract
Ependymomas are rare neoplasms of the central nervous system. Disease-free survival after relapse is poor and approaches to treatment in recurrent disease often palliative. This overview summarises the management of primary disease for which broad consensus exists. We also extensively review treatment options in relapsed disease for which approaches to treatment are varied due to the paucity of literature evidence. Incorporated in this overview is a survey of UK neuro-oncology units to form a snapshot of current UK practise with respect to preferred systemic therapy regimens for patients with recurrent ependymoma. The outcome reflects a preference for mainly oral-based regimens. Universal guidance is lacking in the management of non-operable irradiated recurrent ependymoma and there are worthy therapeutic avenues for further investigation, in particular the role of radical re-irradiation and also the potential of bevacizumab in advanced disease. It is hoped that advances can be achieved by multicentre collaboration in future studies to overcome the difficulties posed by achieving meaningful data in such a rare tumour with extensive natural history.

Abstract
We report a rare case of extraneural metastasis of spinal ependymoma that developed over a very long period. A 28-year-old man underwent surgery for ependymoma in the cauda equina. After he experienced three local recurrences and had undergone five operations, a lung metastasis occurred 46 years after the first operation. Although the tumor did not show the typical morphological malignancy, the maximum standard uptake value obtained by positron-emission tomography and the antigen Ki-67 labeling index demonstrated the tumor's active proliferative ability. One year after the last operation, the patient died of respiratory failure due to progressing lung metastases. The malignant behavior of spinal ependymomas is demonstrated in a case with long-term follow-up.

Abstract
BACKGROUND AND IMPORTANCE Ependymomas are the most frequent intramedullary neoplasms in adult patients. Anaplastic histology, extramedullary location, meningeal dissemination at initial diagnosis, and extraneural metastases are rare findings. We describe a case of extramedullary anaplastic ependymoma that presented with holocordal and intracranial leptomeningeal carcinomatosis and bone metastases in all the vertebral bodies and the sternum. Such an aggressive dissemination at initial diagnosis has not been previously reported. CLINICAL PRESENTATION A 36-year-old woman presented with headache, multiple cranial nerve palsies, visual hallucinations, confusion, hemiparesis, hemihipoestesia, episodes of disconnection, and toxic syndrome. Magnetic resonance imaging and positron emission tomography scan revealed leptomeningeal carcinomatosis in the brainstem, the cerebellum, and along the whole spinal cord. Various nodular, intradural extramedullary lesions were present at multiple dorsal and lumbar levels. Metastatic bone disease affected all the vertebral bodies and various extraspinal bones. An intradural and bone biopsy was performed at L4, providing the diagnosis of anaplastic ependymoma (World Health Organization grade III) with focal neuronal differentiation. Despite chemotherapy, the patient's symptoms quickly progressed, and she died 7 weeks after diagnosis. CONCLUSION To our knowledge, there are no previous descriptions of ependymomas with this extensive leptomeningeal, spinal, intracranial, and extraneural dissemination at clinical onset. Bone metastases in spinal ependymoma have not been previously reported.

Abstract
We report on a 59-year old woman with three huge intrathoracal masses that were accidentally diagnosed when she consulted a physician for upper abdominal discomfort. A biopsy revealed that they were metastases of a coccygeal myxopapillary ependymoma, resected 20 years before. As neither resection, debulking, nor radiation therapy were considered to be indicated, systemic therapy with temozolomide was started. At the first evaluation after four months, the metastases had progressed. Imatinib delayed the progression, but had to be stopped after six months because of critical increased pleural effusion. Using the multikinase inhibitor sorafenib, the disease was stabilized and an acceptable quality of life could be obtained for one year.

Abstract
OBJECT Primary spinal cord ependymomas (EPNs) are rare in children, comprising classical WHO Grade II and III tumors and Grade I myxopapillary ependymomas (MEPNs). Despite their benign histology, recurrences and neural-axis dissemination have been reported in up to 33% MEPNs in the pediatric population. Treatment options beyond resection are limited, and little is known about their tumorigenesis. The purpose of this study was to explore the tumor biology and outcomes in a consecutive series of pediatric patients treated at a single institution. METHODS The authors performed a retrospective clinicopathological review of 19 patients at a tertiary referral children's hospital for resection of a spinal cord ependymoma. The population included 8 patients with a pathological diagnosis of MEPN and 11 patients with a pathological diagnosis of spinal EPN (10 cases were Grade II and 1 case was Grade III). The upregulation of the following genes HOXB13, NEFL, PDGFRα, EGFR, EPHB3, AQP1, and JAGGED 1 was studied by immunohistochemistry from archived paraffin-embedded tumor samples of the entire cohort to compare the expression in MEPN versus EPN. RESULTS Gross-total resection was achieved in 75% of patients presenting with MEPNs and in 100% of those with EPNs. The average follow-up period was 79 months for the MEPN subset and 53 months for Grade II/III EPNs. Overall survival for both subsets was 100%. However, event-free survival was only 50% for patients with MEPNs. Of note, in all cases involving MEPNs that recurred, the patients had undergone gross-total resection on initial surgery. In contrast, there were no tumor recurrences in patients with EPNs. Immunohistochemistry revealed no significant differences in protein expression between the two tumor types with the exception of EPHB3, which demonstrates a tendency to be positive in MEPNs (6 reactive tumors of 9) rather than in EPN (2 reactive tumors of 10). CONCLUSIONS The authors' experience shows that, following a gross-total resection, MEPNs are more likely to recur than their higher-grade counterpart, EPNs. This supports the recommendation for close long-term radiological follow-up of pediatric patients with MEPNs to monitor for recurrence, despite the tumor's low-grade histological feature. No significant difference in the protein expression of HOXB13, NEFL, PDGFRα, EGFR, EPHB3, AQP1, and JAGGED 1 was present in this selected cohort of pediatric patients.

Abstract
Ependymomas are neoplasms that can occur anywhere along the craniospinal axis. They are the third most common brain tumor in children, representing 10% of pediatric intracranial tumors, 4% of adult brain tumors, and 15% of all spinal cord tumors. As the heterogeneity of ependymomas has severely limited the prognostic value of the World Health Organization grading system, numerous studies have focused on genetic alterations as a potential basis for classification and prognosis. However, this endeavor has proven difficult due to variations of findings depending on tumor location, tumor grade, and patient age. While many have evaluated chromosomal abnormalities for ependymomas as a whole group, others have concentrated their efforts on specific subsets of populations. Here, we review modern findings of chromosomal analyses, their relationships with various genes, and their prognostic implications for intracranial and spinal cord ependymomas.

Abstract
Ependymomas are uncommon tumors that arise in the brain, spinal cord or cauda equina. Myxopapillary ependymomas is located exclusively in the conus medullaris or cauda equina, or film terminale region. In most myxopapillary ependymomas, the histological examination reveals low mitotic activity that is associated with a low MIB-1 labeling index (LI). The prognosis is generally favorable, when the appropriate treatment, including a total resection, is performed. The authors encountered a 39-year-old man with multifocal type of myxopapillary ependymomas compressing the cauda equina from the L2 to L3 level and L5-S1 level. A subtotal resection of the tumor was carried out. The histological examination revealed extremely high mitotic activity with a MIB-1 LI of 9.1%. Therefore, cranio-spinal radiation was added after surgery. The postoperative course was uneventful over the 3.5 year follow-up period.

Abstract
Anaplastic ependymoma is a malignant glial tumor thought to arise from radial glial cells of the ventricular zone. Because ependymoma is frequently encountered within ventricular spaces, they are prone to leptomeningeal dissemination. Metastatic extracranial ependymoma has been reported, but in the context of progressive intracranial disease. We report on a boy who developed isolated extracranial recurrence of his anaplastic ependymoma, initially at the scalp and later metastases to cervical lymph nodes. The location of tumor recurrence proximate to the surgical site suggested surgical seeding. This case demonstrates an unusual site of recurrence of anaplastic ependymoma and highlights a previously underappreciated surgical complication.

Abstract
Malignant gliomas account for approximately 60% of all primary brain tumors in adults. Prognosis for these patients has not significantly changed in recent years-despite debulking surgery, radiotherapy and cytotoxic chemotherapy-with a median survival of 9-12 months. Virtually no patients are cured of their illness. Malignant gliomas are usually locally invasive tumors, though extra-neural metastases can sometimes occur late in the course of the disease (median of two years). They generally appear after craniotomy although spontaneous metastases have also been reported. The incidence of these metastases from primary intra-cranial malignant gliomas is low; it is estimated at less than 2% of all cases. Extra-neural metastases from gliomas frequently occur late in the course of the disease (median of two years), and generally appear after craniotomy, but spontaneous metastases have also been reported. Malignant glioma metastases usually involve the regional lymph nodes, lungs and pleural cavity, and occasionally the bone and liver. In this review, we present three cases of extra-neural metastasis of malignant gliomas from our department, summarize the main reported cases in literature, and try to understand the mechanisms underlying these systemic metastases.

Abstract
Ependymomas are glial central nervous system (CNS) tumors that arise from the ependymal layer of brain and spinal cord. These are heterogeneous group of tumors with varied histopathological features and prognosis. They frequently relapse at the primary site and may disseminate to other CNS sites. Extraneural metastases are, however, extremely rare. We present a case of ependymoma in a child with widespread metastasis to her bones, a previously unreported event.

Abstract
Introduction The authors report a rare case of primary spinal ependymomatosis in a young adult man. Multiple primary ependymomatous lesions were seen on magnetic resonance imaging and no anaplasia was identified on the surgical-pathological analysis. The aetio-pathological mechanism and surgical significance of this rare occurrence is discussed. Case presentation A 26-year-old man of Polish origin presented with a ten-day history of pain in the left leg and lower back. This was followed by difficulty in urinating and a decrease in sensation in both legs. Examination revealed pyramidal signs and mild weakness in both lower limbs. He had early sphincter involvement requiring catheterization. Magnetic resonance imaging of the brain was normal. However, that of the spinal cord revealed multiple intradural spinal lesions, both intra- and extramedullary, extending from the cervical cord down to the cauda equina roots. T12-L1 laminectomy was performed. Multiple intradural, extra- and intra-medullary tumors were seen. After the operation, the patient deteriorated with a sensory level at T4. Post-operative cranio-spinal radiotherapy was administered but there was no clinical improvement in the lower limbs. Conclusion Primary spinal ependymomatosis is a rare phenomenon involving multiple spinal segments in the absence of a primary intracranial tumor. Radical excision is unrealistic in this condition. Biopsy followed by radiotherapy is the preferred method of treatment.

Abstract
PURPOSE OF REVIEW To review state of art and relevant advances in the molecular biology and management of ependymomas of the adult. RECENT FINDINGS Ependymomas of the adult are uncommon neoplasms of the central nervous system, and may occur either in the brain or the spinal cord. Compared with intracranial ependymomas, spinal ependymomas are less frequent and exhibit a better prognosis. Studies performed on genetic changes in ependymoma provide some insight into the pathogenesis and prognostic markers and yield new therapeutic targets, particularly focused on signal transduction modulators. The majority of studies have shown a major impact of extent of resection; thus, a complete resection must be performed, whenever possible, at first surgery or at reoperation. Involved field radiotherapy is recommended for anaplastic or incompletely resected grade II tumors. Craniospinal irradiation is reserved for metastatic disease. Chemotherapy is not advocated as primary treatment, and is best utilized as salvage treatment for patients failing surgery and radiotherapy. SUMMARY Owing to the rarity of the disease, the literature regarding ependymomas in adults is scarce and limited to retrospective series. Thus, the level of evidence regarding therapeutic strategies is low and universally accepted guidelines are lacking. Molecular biology studies suggest some potential new therapeutic targets.

Abstract
Myxopapillary ependymomas, a specific tumor variant of spinal cord ependymomas, occur most commonly in the lumbosacral region. During the study period, 1,013 patients underwent surgery for spinal cord tumors. Fifty-two of the patients had a myxopapillary ependymoma. Forty-eight of these patients underwent surgery at our institutions. There were four patients who came for consultations only. Fourteen pediatric patients were diagnosed with myxopapillary ependymoma. The overall average age at which a patient was diagnosed was 31.8 years. The average age a child was diagnosed was 12.6 years. The adult mean age was 38.7 years. The clinical presentation was of a slow, indolent course, with average symptom duration of 20.8 months. Overall, the pediatric patients had a much more aggressive clinical course with a much higher rate of local recurrence and dissemination of the tumor within the neural axis (64% versus 32%). The median time to disease recurrence was 88 months for the entire group. The overall survival after 11.5 years of follow-up was 94%. The optimal management of patients harboring myxopapillary ependymomas remains somewhat controversial. Excellent outcomes may be obtained, however, with the use of aggressive surgical techniques. No clear benefit for adjunctive chemotherapy, and radiation therapy was demonstrated.

Abstract
PURPOSE Metastatic ependymoma is exceedingly rare at diagnosis with variable prognosis reported in the literature. The purpose of this study was to identify prognostic factors in children with metastatic ependymoma. PROCEDURE Data regarding diagnosis, treatment and follow-up for 40 patients from eight institutional cohorts were collected. RESULTS Twenty-nine (72%) patients were less than 36 months of age at the time of diagnosis, 28% were females, and 90% of the patients had posterior fossa tumors. Gross total resection (GTR) of the primary tumor was achieved in 16 patients (40%). Adjuvant therapy was variable and included craniospinal irradiation (CSRT), chemotherapy, and chemotherapy with focal irradiation. The 5-year event free survival (EFS) and overall survival (OS) from the time of diagnosis were 29% (+/-7%) and 43% (+/-8%), respectively. Age at diagnosis was associated significantly with both EFS and OS (P < 0.001 for EFS, and P = 0.01 for OS). Patients who were 24-35 months of age at diagnosis had a 5-year EFS of 66% and a 5-year OS of 73%; both survival rates were superior to those of patients younger than 24 months of age or older than 36 months. Patients with GTR achieved a 5-year EFS of 35% and OS of 59%, compared to a 5-year EFS of 25% and OS of 32% for patients who did not achieve GTR (P = 0.12 for EFS, P = 0.03 for OS). CONCLUSIONS GTR should be attempted in patients with metastatic ependymoma. A subgroup of patients between 24 and 35 months might have a favorable outcome.

Abstract
Glioblastoma, (grade IV astrocytoma), is characterized by rapid growth and resistance to treatment. Identification of markers of aggressiveness in this tumor could represent new therapeutic targets. Interleukins (IL)-6 and IL-10 may be considered as possible candidates, regulating cell growth, resistance to chemotherapy and angiogenesis. ELISPOT method provides a useful tool for the determination of the exact cell number of peripheral lymphocytes secreting a specific cytokine. IL-6 and IL-10 secretion levels were determined using ELISPOT methodology in peripheral blood mononuclear cells of 18 patients with astrocytic neoplasms (3 grade II and 15 grade IV), in parallel with 18 healthy controls. Additionally, immunohistochemical expression of these two cytokines was performed in paraffin-embedded neoplastic tissue in 12 of these patients. The secretion of IL-6 from peripheral monocytes was significantly higher in glioma patients compared to controls (P = 0.0003). In addition, IL-10 secretion from peripheral mononuclear and tumor cells of glioma patients was also higher as compared to healthy controls (P = 0.0002). Based on immunohistochemical staining, IL-6 expression was localized in tumor cells and macrophages as well as in areas of large ischemic necrosis, while the major source of IL-10 expression in glioblastomas was the microglia/macrophage cells. It is suggested that IL-10 contributes to the progression of astrocytomas by suppressing the patient's immune response, whereas IL-6 provides an additional growth advantage. This study demonstrates for the first time the usefulness of ELISPOT in estimating the secretion of IL-6 and IL-10 from peripheral blood and the correlation of their expression in neoplastic cells.

Abstract
OBJECT Currently, the optimal treatment of children harboring myxopapillary ependymomas of the spinal cord remains somewhat debatable. The authors present a retrospective study in which they evaluated the records of patients in whom resection of these lesions had been performed. METHODS Fourteen pediatric patients who had undergone resection of a spinal cord tumor between September 1982 and July 2004 were identified from the database as having histologically classified myxopapillary ependymomas. There were 10 boys and four girls ranging in age from 7 to 18 years (mean age 12.6 years); 71% of the patients were boys. The clinical presentation of the tumor's course was slow and indolent, and the patients had a mean symptom duration of 19.6 months. Twelve patients, who underwent a total of 16 operations, were available for long-term follow-up review. Thirteen gross-total resections and three subtotal resections were performed. There were no deaths due to surgery. Postoperatively, patients initially remained at their preoperative level of function or improved. Patients who had undergone previous surgery and radiotherapy were treated more conservatively than patients who were undergoing surgery for the first time. Four children experienced significant complications following treatment. CONCLUSIONS As the authors demonstrate in this study, excellent outcomes may be obtained with the use of aggressive surgical techniques with the goal being that of gross-total resection. Despite the best of resections, however, the risk of recurrence remains. Therefore, periodic neuroimaging surveillance of the neuraxis and close clinical follow up are warranted throughout the patient's life. The role for adjunctive chemo- and radiotherapy remains to be defined in the management of myxopapillary ependymomas.

Abstract
Myxopapillary ependymomas (ME) are considered benign tumours (WHO grade I) of the central nervous system with long term survival rates and a tendency to local recurrence. However an aggressive course has occasionally been described, leading to CSF dissemination and even systemic metastases. We describe the case of a 23-year-old man diagnosed with intracranial subarachnoid dissemination of a filum terminale ME three years after the initial diagnosis. We have performed a careful review of the literature on CSF dissemination in ME and finally propose treatment of these cases.

Abstract
A 25-year-old woman presented in 2002 with progressive shortness of breath and weight loss. A computed tomographic scan of the chest showed a huge anterior mediastinal mass, and pathological examination of a mediastinoscopic needle biopsy revealed typical myxopapillary ependymoma, an extremely unusual diagnosis at this site. Further workup and questioning of the patient revealed that she had opted not to disclose a history of surgery for right gluteal fold mass in 1993, which was primarily treated with surgery followed by radiotherapy for relapse. Review of the histology of the excised mass showed a myxopapillary ependymoma, similar to current histology. Clinical examination of the local gluteal and paracoccygeal site, computed tomographic imaging, and magnetic resonance imaging failed to demonstrate any evidence of recurrent disease in soft tissue or bone. The case is presented, and this very unusual presentation is discussed.
