Abstract
Introduction and importance Ependymomas are central nervous system tumors arising from the ependymal lining of the ventricle and spinal cord. Supratentorial extra-axial ependymomas are very rare, most commonly affecting the pediatric population and rarely in adults. Case presentation The authors report a case of a 71-year-old female with a headache and blurred vision. An MRI scan revealed a lesion at the parafalcine region of the occipital lobe. A parieto-occipital craniotomy was performed. When the dura was opened during the operation, the extra-axially located, well-circumscribed, dirty yellow-white tumor dissected from the surrounding tissue was excised entirely by microdissection. Histopathological examination revealed supratentorial extra-axial anaplastic ependymoma. The patient received postoperative radiation therapy (54 Gray over 30 fractions). No recurrence of the tumor was observed during the 4-year follow-up. Discussion Supratentorial ependymomas at the extra-axial region are uncommon; extra-axial anaplastic ependymoma and meningiomas have similar radiological findings, such as a dural tail, subarachnoid plane, and diffuse enhancement after contrast injection. This close similarity might cause misdiagnoses. Total surgical resection was followed by adjuvant radiotherapy and close follow-up in the gold standard of the treatment. Conclusion The authors report a rare case of anaplastic ependymomas located at the extra-axial region. Anaplastic tumors are prone to recurrence despite total resection and radiation therapy; hence, a close follow-up is warranted.

Abstract
Ependymoma is a rare adult tumor that originates from ependymal cells of the central nervous system, primarily occurring in the cerebral ventricles or the central canal of the spinal cord. In this paper, we report a case of extensive leptomeningeal seeding of ependymoma of a 39-year-old male patient, in whom the tumor was found incidentally after head trauma. The MRI exhibited diffuse leptomeningeal infiltrative lesions along with bilateral multiple cerebral sulci, basal cisterns, cerebellopontine angle, cerebellar folia. It also showed multinodular enhancing T1 low T2 high signal intensity lesions along the whole spinal cord. After the tumor biopsy at right temporal lesion, pathologic diagnosis was classic ependymoma (WHO grade 2). The patient has undergone radiation therapy and chemotherapy, and is currently maintaining a stable condition two years after surgery. This report suggests that when considering the differential diagnosis of extensive lesions both in the intracranial and intraspinal space, ependymoma should also be considered.

Abstract
Supratentorial extraventricular ependymomas (STEE) are very rare primary tumors of the central nervous system (CNS). A 19-year-old man complained of headache, hemiparesis and seizures and was admitted to our hospital. Magnetic resonance imaging (MRI) revealed a right frontal intra-axial lesion. The patient underwent surgical treatment, and the tumor was resected successfully. A diagnosis of World Health Organization (WHO) grade 3 STEE was based on microscopic examination and immunohistochemical analysis. The patient was discharged without a neurological deficit.

Abstract
Introduction Primary extra-axial ependymomas, though rare, the majority of such lesions are identified as WHO grade III ependymomas. These ependymomas may mimick a meningioma on radiological investigations which can be confirmed by histopathology. Research Question We show in this case report a rare presentation of extra-axial supratentorial ependymoma with concomitant subdural hematoma mimicking a parasagittal meningioma. Material and Methods A 59 years lady with no known comorbidities presented with weakness of right half of body and decreased speech for 2 days. She was aphasic. Contrast MRI brain revealed an extra-axial dural-based homogenously enhancing lesion in the left anterior 1/3rd parasagittal area with left frontotemporoparietal chronic subdural hematoma. With a provisional diagnosis of meningioma, the patient was subjected to bifrontal open-book craniotomy with gross total excision of lesion with periosteal graft duraplasty and acrylic cranioplasty. Left sided frontotemporal subacute SDH with thin greenish yellow membrane was present. In post operative period, patient quickly became E4V5M6 with power of 4/5 in the right half of body which was same as compared to the preoperative period. Results The biopsy of the mass, however, revealed features suggestive of extra-axial supratentorial ependymoma (WHO Grade III). Immunohistochemistry supported the diagnosis of supratentorial ependymoma, NOS. The patient was then referred for further chemoradiation. Discussion and Conclusion We report the first case of extra-axial supratentorial ependymoma mimicking a parasagittal meningioma occurring with adjacent subdural hematoma. Clinical and imaging background along with a complete pathological examination with immunohistochemical study is essential to confirm the diagnosis of rare brain tumours.

Abstract
Pineal region tumors fall into five broad categories: benign pineal region tumors, glial tumors, papillary tumors, pineal parenchymal tumors, and germ cell tumors. Genetic and transcriptional studies have identified key chromosomal alterations in germinomas (RUNDC3A, ASAH1, LPL) and in pineocytomas/pineoblastomas (DROSHA/DICER1, RB1). Pineal region tumors generally present with symptoms of hydrocephalus including nausea, vomiting, papilledema, and the classical Parinaud's triad of upgaze paralysis, convergence-retraction nystagmus, and light-near pupillary dissociation. Workup requires neuroimaging and tissue diagnosis via biopsy. In germinoma cases, diagnosis may be made based on serum or CSF studies for alpha-fetoprotein or beta-HCG making the preferred treatment radiosurgery, thereby preventing the need for unnecessary surgeries. Treatment generally involves three steps: CSF diversion in cases of hydrocephalus, biopsy through endoscopic or stereotactic methods, and open surgical resection. Multiple surgical approaches are possible for approach to the pineal region. The original approach to the pineal region was the interhemispheric transcallosal first described by Dandy. The most common approach is the supracerebellar infratentorial approach as it utilizes a natural anatomic corridor for access to the pineal region. The paramedian or lateral supracerebellar infratentorial approach is another improvement that uses a similar anatomic corridor but allows for preservation of midline bridging veins; this minimizes the chance for brainstem or cerebellar venous infarction. Determination of the optimal approach relies on tumor characteristics, namely location of deep venous structures to the tumor along with the lateral eccentricity of the tumor. The immediate post-operative period is important as hemorrhage or swelling can cause obstructive hydrocephalus and lead to rapid deterioration. Adjuvant therapy, whether chemotherapy or radiation, is based on tumor pathology. Improvements within pineal surgery will require improved technology for access to the pineal region along with targeted therapies that can effectively treat and prevent recurrence of malignant pineal region tumors.

Abstract
Ependymomas are unusual neuroepithelial tumors of the central nervous system that arise from clusters of ependymal cells. In adults, ependymomas are the most common primary spinal cord tumors. Nevertheless, only a few cases of large-cell ependymoma have been documented; these cases often involve the brain. Here, we report the case of a 43-year-old man who had a cervical spinal cord ependymoma with syringomyelia. The giant-cell ependymoma (GCE) in the spinal cord discussed in this case emphasizes the characteristics of GCE and the discrepancy between the pathological appearance, the surgical results, and the clinically good prognosis.

Abstract
BACKGROUND The differentiation of supratentorial pilocytic astrocytomas (STPAs) and supratentorial extraventricular ependymomas (STEEs) is clinically pivotal because of distinct therapeutic management and prognosis, which is sometimes challenging to both neuroradiologists and pathologists. PURPOSE To explore and compare the conventional and advanced magnetic resonance imaging (MRI) features between STPA and STEE. MATERIAL AND METHODS A total of 23 patients with STPAs and 23 patients with STEEs were reviewed in this study. All patients performed conventional MRI, susceptibility-weighted imaging (SWI), and diffusion-weighted imaging (DWI), and 34 patients (17 with STPAs and 17 with STEEs) examined dynamic susceptibility contrast-enhanced perfusion-weighted imaging (DSC-PWI) in addition. Clinical data, conventional MRI features, minimum relative apparent diffusion coefficient ratio (rADCmin), and maximum relative cerebral blood volume ratio (rCBVmax) were compared between the two groups and subgroups. The optimal cutoff values of rADCmin and rCBVmax with sensitivity and specificity were calculated. RESULTS STPA manifested similar to STEE as a solid-cystic mass but more frequently presented with a marked enhancing deep nodule (P = 0.02), no peritumoral edema (P = 0.036), higher rADCmin value (2.0 ± 0.5 vs. 0.9 ± 0.2; P < 0.001), and lower rCBVmax value (2.1 ± 0.4 vs. 14.4 ± 5.5; P < 0.001). The cutoff value of >1.39 for rADCmin and ≤ 2.81 for rCBVmax produced a high sensitivity of 95.65% and 100.0%, respectively, and all produced a specificity of 100.0% in differentiating STPAs from STEEs. CONCLUSION Multiparametric MRI techniques including conventional MRI, DWI, and DSC-PWI contribute to the differential diagnosis of STPA and STEE.

Abstract
Ependymomas are primary glial tumors arising from cells related to the ependymal lining of the ventricular system. They are classified into at least nine different molecular subtypes according to molecular phenotype, histological morphology, and tumor location. Primary sellar ependymoma is an extremely rare malignancy of the central nervous system, with only 12 known cases reported in humans. We herein report a case of ependymoma located at the pituitary region in a 44-year-old female patient and discuss the molecular subtype, natural history, clinical presentation, radiological findings, histological features, immunohistochemical characteristics, ultrastructural examinations, treatment, and prognosis of sellar ependymoma. This case report may serve as a helpful reference for clinicians and radiologists in clinical practice.

Abstract
Aim Survival rates and prognostic factors of cortical ependymomas (CEs) remain elusive. This study aimed to perform a comprehensive analysis of prognostic factors, treatment, and outcomes for patients with CEs based on institutional and literature case series. Materials and Methods Thirty patients with CEs from our department were included in this study. Furthermore, a systemic review of the literature yielded an additional 106 patients with CEs. Clinical data including patient age, sex, symptoms, tumor location, World Health Organization (WHO) grade, extent of surgery, radiation, recurrence, and survival were recorded and statistically analyzed. Results From January 2009 to October 2019, 30 (4.2%) cases were diagnosed as CEs in our department. These series consisted of 19 males and 11 females, 10 continuous patients after 2017 screened for C11orf95-RELA fusion, and 9 patients (90%) were RELA fusion positive. During the follow-up period, nine (30%) patients depicted tumor recurrence or progression; four (13.3%) patients died of tumor progression. The literature review yielded 106 CE cases, with additional 30 cases of our own collected for further analysis. Of these 136 cases, the frontal lobe (40%) was the most common location, and the average age was 22.6 ± 17.6 years. Anaplastic histology/WHO grade III tumors were identified in 68 (50%) patients. Statistically analysis demonstrated that extent of surgery and WHO tumor grade were significant prognostic factors in Kaplan–Meier log-rank testing and Cox proportional hazards models. Gross total resection (GTR) predicted longer progression-free survival (PFS) [P = 0.013, hazard ratio (HR) = 3.012, 95% confidence interval (CI) = 1.257–7.213] and overall survival (OS) (P = 0.003, HR = 5.322, 95% CI = 1.751–16.178). WHO grade III tumors had worse PFS (P = 0.002, HR = 5.17, 95% CI = 1.804–14.816) and OS (P = 0.025, HR = 5.640, 95% CI = 1.248–25.495). Conclusion CEs accounted for only 3.5 to 5.7% of ependymomas, with seizures the most common symptom and the frontal lobe the most frequent location. CEs may have higher rate of RELA fusions, but generally favorable prognosis. The extent of surgery and WHO tumor grade were significant prognostic factors for PFS and OS in multivariate analysis. GTTR or WHO grade II tumors had better overall outcome in patients with CEs.

Abstract
OBJECTIVE. The purpose of this study was to investigate and compare conventional MRI, DWI, and dynamic susceptibility contrast-enhanced perfusion-weighted imaging (DSC-PWI) characteristics between low-grade and anaplastic extraventricular ependymomas. MATERIALS AND METHODS. Twenty-six patients with extraventricular ependymomas (19 anaplastic and seven low-grade) who underwent preoperative MRI were enrolled in this retrospective study. Conventional MRI and DWI were performed in all patients; DSCPWI was performed in 15 patients (11 with anaplastic ependymoma and four with low-grade ependymoma). Demographics, conventional MRI features, minimum relative apparent diffusion coefficient (rADCmin), and maximum relative cerebral blood volume (rCBVmax) of the low-grade and anaplastic ependymomas were compared. Diagnostic performance with optimal cutoff values was determined. RESULTS. Anaplastic extraventricular ependymomas were more likely to be located in the superficial supratentorial cerebral hemisphere (p = 0.026) and to present with pial and cortical involvement (p = 0.028 and 0.013, respectively) and necrotic degeneration (p = 0.014). The mean rADCmin ± SD of anaplastic ependymoma was significantly lower than that of low-grade ependymoma (0.8 ± 0.2 vs 1.2 ± 0.3, p = 0.002). The mean rCBVmax of anaplastic ependymoma was significantly higher than that of low-grade ependymoma (15.7 ± 5.3 vs 9.0 ± 4.4, p = 0.042). The cutoff values in grading extraventricular ependymoma were 1.02 for rADCmin and 10.43 for rCBVmax. Combining conventional MRI, DWI, and DSC-PWI allowed the best differentiation of low-grade and anaplastic ependymoma (AUC = 1.00). CONCLUSION. Conventional MRI, DWI, and DSC-PWI techniques may aid in assessing and grading extraventricular ependymomas.

Abstract
Context: Supratentorial ependymomas and their anaplastic variants are relatively uncommon central nervous system neoplasms that afflict both adults and children. Aims: Discuss the clinical and pathological features of patients with anaplastic ependymomas involving an extraventricular supratentorial location and review modalities and options of treatment for those rare tumors. Settings and Design: Whereas the treatment algorithm in the pediatric population is well established, however, treatment in the adult population is less defined. Treatment options are exposed through the author's cases and review of the literature. Subjects and Methods: In our case series of two adult patients with supratentorial ependymomas World Health Organization (WHO) Grade III (anaplastic variant), patients presented in both cases in the emergency room after having a generalized tonic–clonic seizure at home the first case, and mild hemiparesis the second case. Results: Patients underwent surgical treatment, and a gross total resection was achieved in both cases. The histopathological examination revealed a diagnosis of anaplastic ependymoma (WHO Grade III). Both patients had additional radiotherapy, and in the first case, adjuvant platinum-based chemotherapy was administered due to leptomeningeal gliomatosis. Conclusion: In our experience, gross total resection was achieved in all patients with supratentorial extraventricular ependymomas WHO Grade III with additional radiotherapy and platinum-based chemotherapy. Patients require initial close serial imaging follow-up. The role of chemotherapy is still uncertain but may be necessary in younger patients and in tumors that behave more like the pediatric ependymomas.

Abstract
Cortical ependymomas (CE) are rare subset of supratentorial ependymoma which are located in the peripheral cortical rim without any connection to the ventricular lining. With limited cases previously reported, current knowledge on diagnosis and management of tumors is lacking. We present the largest single center experience on CE reported so far and highlight their clinico-radiological aspects, histopathological features as well the results of their surgical excision. We studied 18 CE patients undergoing surgical excision at our center between September 2009 to November 2017. Clinical, radiological, histopathological and operative data was obtained from hospital records. Functional assessment of our patients were done using the Karnofsky's performance score (KPS). Survival analysis was done using Kaplan-Meier method and log rank test. Mean age of patients in our study group was 19 ± 11.1 years. Frontal lobe was the most frequently involved region. Features of raised intracranial pressure like holocranial headache (n = 15, 83.33%) and vomiting (n = 9, 50%) were most common presenting complaints in our study. Gross total resection of tumor was achieved in eleven patients (61.11%). Histopathology showed equal number (n = 9) of WHO grade 2 and 3 ependymoma. During 111 months follow-up, four patients (22.22%) developed recurrence and three patients (16.66%) died. Five years overall survival (OS), progression-free survival (PFS) rate were 74.3% and 70.7%. In view of higher risk of progression to higher histo-pathological grade and local recurrence years after surgical excision, a long clinical and radiological follow-up is advised.

Abstract
BACKGROUND Supratentorial extraventricular ependymoma (STEE) is an extremely rare central nervous system (CNS) neoplasm, the clinical characteristics and optimal treatment of which remain unclear. We retrospectively analyzed the clinical characteristics and treatment outcomes of 15 patients with STEE. METHODS Fifteen patients with STEE were identified, and their clinical, radiologic, and surgical records were reviewed. RESULTS The 15 patients included 6 males (40%) and 9 females (60%), with a median age of 15 years. Nine patients (60%) underwent gross total resection, 5 patients (33.3%) underwent subtotal resection, and 1 patient (6.7%) underwent biopsy. Eight patients received adjuvant radiotherapy, and 3 received adjuvant chemotherapy. The 5-year overall survival (OS) rates of patients with World Health Organization (WHO) grade II and grade III STEE were 100% and 30%, respectively, and the corresponding 2-year progression-free survival (PFS) rates were 77.8% and 20%. The differences in OS and PFS rates between WHO grades II and III STEE were statistically significant (P < 0.01 and 0.02, respectively). Anaplastic histology (WHO grade III) was a poor prognostic factor for PFS (P = 0.04). The recurrence pattern was local recurrence in all patients; all cases were treated primarily by redo surgery. Three patients with recurrent WHO grade II STEE were alive at more than 64, 52, and 44 months after redo surgery. CONCLUSIONS STEE is an extremely rare CNS neoplasm. The histological grade of STEE is an important prognostic factor. Microsurgical resection might play a major role in both initial treatment and treatment of recurrent tumors.

Abstract
OBJECTIVE Cortical ependymomas (CEs), supratentorial ependymomas that selectively involve the cerebral cortex, are relatively rare neoplasms that have not been extensively described. The purpose of our study was to identify the clinical features, radiologic characteristics, and treatment of a series of such tumors. METHODS Thirteen patients with CEs from our hospital were included in this study. Epidemiologic characteristics, clinical features, imaging findings, treatment methods, and clinical outcomes were reviewed retrospectively. RESULTS The patients consisted of 7 men and 6 women with mean age of 31.1 ± 23.2 years (range, 4-74 years). The most common clinical manifestation was seizure (n = 11; 85%), followed by headache (n = 2; 15%). None of the tumors were incidentally detected. Eight CEs were located in the right hemisphere and 5 in the left side. The 2 most common tumor locations were the frontal (n = 5; 38%) and parietal lobe (n = 5; 38%). All patients underwent surgical resection. Gross total resection was achieved in 12 patients (92%), and subtotal resection was performed in 1 patient (8%). Ten of the 11 patients who presented with seizure are seizure-free after surgery (91% seizure-free rate). According to the World Health Organization classification system, 9 tumors (69%) were Grade II (ependymoma) and 4 (31%) were Grade III (anaplastic ependymoma). The mean follow-up was 52 months (range, 20-88 months). No recurrence was observed in patients with Grade II CEs. Of 4 patients with Grade III CEs, 2 (50%) suffered from tumor recurrence after initial treatment. CONCLUSIONS CEs are a rare subset of supratentorial ependymomas that selectively involve the cerebral cortex. Most CEs are low grade and present with seizures. Anaplastic CEs show a greater recurrence rate and a relatively poor prognosis. Gross total resection with or without adjuvant radiotherapy is currently the optimal treatment for CEs. CEs seem to have a more favorable prognosis than other supratentorial ependymomas.

Abstract
OBJECTIVE Supratentorial extraventricular ependymomas are relatively rare. Long-term outcomes and prognostic factor for this rare tumor have not been well established. The purpose of this study was to demonstrateprogression-freesurvival(PFS),overallsurvival(OS), and prognostic factors of such tumor. PATIENTS AND METHODS Fifty-five patients with supratentorial extraventricular ependymomas from our hospital were included in this study. Epidemiological characteristics, clinical features, treatment,long-term outcomes, and prognostic factors for PFS and OS were reviewed retrospectively. RESULTS The patients consisted of 30 males and 25 females with mean age of 30.0 ± 23.6 years (range, 1-74 years). Twenty-nine tumors were located in the right hemisphere, and 26 in the left side. The 2 most common tumor locations were the frontal (n = 19; 35%) and parietal lobe (n = 11; 20%). All patients underwent surgical resection. Gross-total resection (GTR) was achieved in 42 cases (76%) and subtotal resection (STR) was performed in 13 patients (24%). According to the WHO classification system, 38 tumors (69%) were Grade III (anaplastic ependymoma), and 17 (31%) were Grade II (ependymoma). Three-,5-, and 10 year PFS rates were 60%, 49%, and 36%, respectively. Three-,5-, and 10 year OS rates were 79%, 64%, and 49%, respectively. EOR and tumor grade were identified as prognostic factors for PFS and OS on univariate analysis, multivariate analysis, and Kaplan-Meierlog-rank testing. Subtotal resection (STR) predicted a worse PFS (HR = 4.808; 95%, 1.942-11.905; P = .001) and OS (HR = 5.650; 95%, 2.114-15.152; P = .001). WHO Grade III tumors also had worse PFS (HR = 3.922; 95%, 1.429-18.182; P = .012) and OS (HR = 6.329; 95%, 1.328-30.303; P = 0.021). For patients with tumor recurrence, reoperation was significant prognostic factors for OS (HR = 2.091; 95%, 0.939-4.654; p = .000). Age, sex, tumor side, and postoperativeradiotherapy were not prognostic factors for PFS and OS. CONCLUSIONS Most supratentorial extraventricular ependymomas are WHO grade III tumors. STRandWHO Grade III pathology predicted worse PFS and OS. Gross-total resection remains the optimal treatment for patients with supratentorial extraventricular ependymoma. Reoperation should be considered first in cases of recurrence. The role of postoperative radiotherapy as an adjuvant treatment for supratentorial extraventricular ependymoma needs further investigation.

Abstract
BACKGROUND Pituitary ependymoma is exceptionally rare. Its etiology, clinical presentation, radiologic feature, and treatment strategy are still a matter of debate. Only 7 human cases with limited data were reported in the English literature, and now we described another case of pituitary ependymoma. We also systematically reviewed previously reported cases and described its potential etiology, clinical presentation, radiologic features, pathology, immunohistochemical analysis, and ultrastructural examinations. CASE DESCRIPTION A lesion in pituitary fossa was discovered in a 40-year-old man after suffering a progressive deterioration of vision in his right eye for >1 year with intermittent headache. The lesion was microsurgically resected and proved to be ependymoma upon pathologic and histologic examination. The patient made a fully recovery after surgery. CONCLUSIONS To our knowledge, only 7 patients with ependymoma in the sellar region have been described in the English literature. We reported 1 more case of pituitary ependymoma and discussed the potential etiology, clinical presentation, radiologic features, pathology, immunohistochemical analysis, ultrastructural examinations, treatment, surgery, radiotherapy, chemotherapy, and prognosis of pituitary ependymoma. The case report may serve as a helpful reference for clinicians and radiologists.

Abstract
OBJECTIVE Reports on supratentorial extraventricular ependymoma (STE) are relatively rare. The object of this study was to analyze the clinical, radiological, and histological features and treatment outcomes of 14 patients with STE. METHODS Overall, 227 patients with ependymoma underwent surgical treatment in the authors' department between January 2010 and June 2015; 14 of these patients had STE. Data on clinical presentation, radiological studies, histopathological findings, surgical strategies, and treatment outcomes in these 14 cases were retrospectively analyzed. RESULTS The patients consisted of 6 women and 8 men (sex ratio 0.75). Mean age at diagnosis was 24.5 ± 13.5 years (range 3-48 years). Tumors were predominantly located in the frontal and temporal lobes (5 and 4 cases, respectively). Typical radiological features were mild to moderate heterogeneous tumor enhancements on contrast-enhanced MRI. Other radiological features included well-circumscribed, "popcorn" enhancement and no distinct adjoining brain edema. Gross-total resection was achieved in 12 patients, while subtotal removal was performed in 2. Radiotherapy was administered in 7 patients after surgery. Seven tumors were classified as WHO Grade II and the other 7 were verified as WHO Grade III. The mean follow-up period was 22.6 months (range 8-39 months). There were 3 patients with recurrence, and 2 of these patients died. CONCLUSIONS Supratentorial extraventricular ependymoma has atypical clinical presentations, various radiological features, and heterogeneous histological forms; therefore, definitive diagnosis can be difficult. Anaplastic STE shows malignant biological behavior, a higher recurrence rate, and a relatively poor prognosis. Gross-total resection with or without postoperative radiotherapy is currently the optimal treatment for STE.

Abstract
BACKGROUND Neoplastic meningitis, also known as leptomeningeal disease, affects the entire neuraxis. The clinical manifestations of the disease may affect the cranial nerves, cerebral hemispheres, or the spine. Because of the extent of disease involvement, treatment options and disease staging should involve all compartments of the cerebrospinal fluid (CSF) and subarachnoid space. Few studies of patients with primary brain tumors have specifically addressed treatment for the secondary complication of neoplastic meningitis. Therapy for neoplastic meningitis is palliative in nature and, rarely, may have a curative intent. METHODS A review of the medical literature pertinent to neoplastic meningitis in primary brain tumors was performed. The complication of neoplastic meningitis is described in detail for the various types of primary brain tumors. RESULTS Treatment of neoplastic meningitis is complicated because determining who should receive aggressive, central nervous system (CNS)-directed therapy is difficult. In general, the therapeutic response of neoplastic meningitis is a function of CSF cytology and, secondarily, of the clinical improvement in neurological manifestations related to the disease. CSF cytology may manifest a rostrocaudal disassociation; thus, consecutive, negative findings require that both lumbar and ventricular cytological testing are performed to confirm the complete response. Based on data from several prospective, randomized trials extrapolated to primary brain tumors, the median rate of survival for neoplastic meningitis is several months. Oftentimes, therapy directed at palliation may improve quality of life by protecting patients from experiencing continued neurological deterioration. CONCLUSIONS Neoplastic meningitis is a complicated disease in which response to therapy varies by histology. Thus, survival rates after CNS-directed therapy will differ by the underlying primary tumor. Optimal therapy of neoplastic meningitis is poorly defined, and few guidelines exist to guide clinicians on the most appropriate choice of therapy.

Abstract
Ependymoma tends to occur commonly along either on ventricular surfaces of the brain or central canal of the spinal cord. Rarely, ependymoma can develop in the cerebral cortex without attachment to the ventricular structures. However, such occurrence in the purely extra-axial compartment in the falcine region mimicking falcine meningioma is exceedingly rare. The detailed search of primary falcine ependymoma (PEFE) in Medline and PubMed yielded only five isolated case reports. All cases occurred in patient older than 17 years of age; however, our case was a 9-year-old girl. PEFE tends to occur more commonly in male with a male to female ratio of 3:2, with the mean age of 28.8 years (range 17–43 years), lesion had intra-operatively had solid consistency in all cases. All cases were subjected to surgical resection followed by adjuvant radiotherapy; however, in addition, one case also received chemotherapy, with an average follow-up period of 9 months, however, missing in one case. The mean size of the tumor was 5.25 cm (range 1.8–7.2 cm). The authors present a unique case of PEFE in a 9-year-old girl with 8.6 cm ×6 cm ×5.4 cm-sized giant primary falcine ependymoma, managed surgically successfully. To the best of the authors' knowledge, the current case is the first case of pediatric extra-axial falcine ependymoma occurring within the first decade of life in the western literature, showing rapid evolution over 1½ month's period into a giant size. Brief pathogenesis, clinical feature, and management along with the pertinent literature are reviewed briefly.

Abstract
OBJECTIVE Survival rates and prognostic factors for supratentorial hemispheric ependymomas have not been determined. The authors therefore designed a retrospective study to determine progression-free survival (PFS), overall survival (OS), and prognostic factors for hemispheric ependymomas. METHODS The study population consisted of 8 patients from our institution and 101 patients from the literature with disaggregated survival information (n = 109). Patient age, sex, tumor side, tumor location, extent of resection (EOR), tumor grade, postoperative chemotherapy, radiation, time to recurrence, and survival were recorded. Kaplan-Meier survival analyses and Cox proportional hazard models were completed to determine survival rates and prognostic factors. RESULTS Anaplastic histology/WHO Grade III tumors were identified in 62% of cases and correlated with older age. Three-, 5-, and 10-year PFS rates were 57%, 51%, and 42%, respectively. Three-, 5-, and 10-year OS rates were 77%, 71%, and 58%, respectively. EOR and tumor grade were identified on both Kaplan-Meier log-rank testing and univariate Cox proportional hazard models as prognostic for PFS and OS. Both EOR and tumor grade remained prognostic on multivariate analysis. Subtotal resection (STR) predicted a worse PFS (hazard ratio [HR] 4.764, p = 0.001) and OS (HR 4.216, p = 0.008). Subgroup survival analysis of patients with STR demonstrated a 5- and 10-year OS of 28% and 0%, respectively. WHO Grade III tumors also had worse PFS (HR 10.2, p = 0.004) and OS (HR 9.1, p = 0.035). Patients with WHO Grade III tumors demonstrated 5- and 10-year OS of 61% and 46%, respectively. Postoperative radiation was not prognostic for PFS or OS. CONCLUSIONS A high incidence of anaplastic histology was found in hemispheric ependymomas and was associated with older age. EOR and tumor grade were prognostic factors for PFS and OS on multivariate analysis. STR or WHO Grade III pathology, or both, predicted worse overall prognosis in patients with hemispheric ependymoma.

Abstract
The present study describes the case of a 63-year-old woman presenting with headache, dizziness and vomiting due to a an ovoid mass in the left pre-bulbar cistern, apparently arising from the lower clivus and the foramen magnum. The clinical history revealed the subtotal removal of a right cerebellar low-grade glioma 15 years previously and subsequent conventional 60-Gy radiotherapy. Notably, following gross total resection, histopathological examination showed microscopic features that resulted in a diagnosis of anaplastic ependymoma. The patient underwent surgery to remove the mass and post-operative chemotherapy with temozolomide. A progressive improvement of neurological signs and symptoms was observed during the postoperative course. At the 6-month follow-up, the patient was free from clinical and radiological recurrence. The unusual features of this rare secondary brain tumor were the extrassial location in the posterior fossa, the unusual age-associated location of the histological subtype and the fact that it closely mimicked a skull-base meningioma.

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

Abstract
Observation following gross-total resection (GTR) for non-anaplastic supratentorial ependymomas is often advocated based on small, retrospective series. The purpose of this study is to perform a population-based analysis to examine outcomes for this rare cohort of low-risk patients. A retrospective analysis was conducted utilizing the Surveillance, Epidemiology and End Results Program of the United States National Cancer Institute. We identified patients with supratentorial non-anaplastic ependymoma who underwent GTR alone or GTR followed by radiation. We identified 92 patients who met these criteria. The median age was 17.5 years (range 1-83) with the majority female (58 %) and white (75 %). Radiotherapy (RT) was delivered in half of patients. The 5-/10-year Kaplan-Meier estimated overall survival (OS) and cause-specific survival (CSS) for the overall cohort was 83.2/71.4 and 84.1/78.0 %, respectively. There was no evidence of decreased CSS (HR 0.52 [0.18-1.51]; p = 0.23) or OS (HR 0.63 [0.25-1.59]; p = 0.33) with the omission of RT on univariate analysis. Age ≥18 years correlated with worse OS (HR 4.01 [1.45-11.11]; p = 0.008) and CSS (HR 2.86 [0.99-8.31]; p = 0.05). RT did not impact outcome for this low-risk cohort of patients. Older age correlates with poor prognosis.

Abstract
Although the World Health Organization (WHO) categorizes spinal ependymomas into three histological grades, difference in surgical outcomes between WHO grades I and II tumors are unclear. For these benign tumors, prognosis may be best determined by factors other than tumor grade alone, such as extent of resection. To analyze the effects of the extent of resection on different grades of spinal ependymomas, we performed a comprehensive literature review to identify adult spinal ependymoma patients who received surgical resection with a clearly identifiable WHO grade. A total of 175 patients were identified. While grade III tumors carried the worst prognosis as expected (p<0.001), grade I and II tumors did not differ significantly in outcomes following surgery. Overall, gross total resection (GTR, 68.7%, 114/166) provided significantly improved progression-free survival (PFS, p<0.001) and overall survival (OS, p=0.022) compared to the subtotal resection group. Surprisingly, the highest GTR rate was achieved for grade II tumors (78.8%, 78/99; p<0.001) followed by grade I (58.9%, 33/56) and grade III tumors (27.3%, 3/11). Interestingly, PFS was significantly improved by GTR for grade II tumors (p<0.001), but not for grade I (p=0.705). Similar trends, although not statistically significant, were found for OS. Our results show that while GTR provides the best overall outcomes, GTR is most effective for classic grade II ependymomas, but not for grade I ependymomas. Despite having a lower WHO grade, myxopapillary ependymomas have a lower GTR rate, and benefit less from GTR.

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

Abstract
We report the case of a 61-year-old man with supratentorial extraventricular anaplastic ependymoma who presented with repeated intratumoral hemorrhage. The patient was admitted with headache. Computed tomography and magnetic resonance imaging showed an enhancing mass with intratumoral hemorrhage in the right temporal lobe. Gross total resection was performed. The tumor was well demarcated from the brain tissue, and showed no continuity with the ventricular system. Histopathological examination revealed the features of anaplastic ependymoma. Therefore, additional radiation therapy and adjuvant chemotherapy were administered. Ten months later, the tumor recurred with hemorrhage in the spinal canal. This case showed rapid malignant progression and repeated intratumoral hemorrhage within a short period of time, both of which are characteristics of anaplastic ependymomas. Close observation of the central nervous system and adjuvant radiotherapy are mandatory, even if the ependymoma presents with repeated intratumoral hemorrhage.

Abstract
BACKGROUND Anaplastic cortical ependymomas are rare lesions with few cases reported in the literature. CASE DESCRIPTION We present a unique case of an anaplastic cortical ependymoma in a 51-year-old female presenting as a butterfly lesion with involvement of both frontal lobes. The patient underwent gross total resection of her tumor with further adjuvant treatment. We present the findings in our case and review the literature surrounding supratentorial ependymomas and their treatment outcomes. CONCLUSION Rarely, cortical ependymoma can present as a butterfly lesion and should be considered in the differential diagnosis of such lesions in adults.

Abstract
Ependymal tumors are reported rarely in domestic animals. The aims of this study were to examine the clinical and pathologic features of ventricular and extraventricular ependymomas and subependymomas in 18 domestic cats examined between 1978 and 2011. Parameters examined included age, sex, breed, clinical signs, and macroscopic and histopathologic features. The mean age of affected cats was 9 years, 4 months; median age, 8.5 years. There were 8 female and 4 male cats, and 6 cats for which sex was not recorded. Breeds included 10 domestic shorthaired, 2 domestic longhaired, 1 Persian, and 1 Siamese. Clinical signs included altered mentation or behavior, seizures, circling, propulsive gait, generalized discomfort, and loss of condition. The tumors often formed intraventricular masses and usually arose from the lining of the lateral or third ventricles, followed by the fourth ventricle, mesencephalic aqueduct, and spinal cord central canal. Three tumors were extraventricular, forming masses within the cerebrum and adjacent subarachnoid space. Histologically, 15 tumors were classified as variants of ependymomas (classic, papillary, tanycytic, or clear cell) and 3 as subependymomas. Tumors were generally well demarcated; however, 6 ependymomas focally or extensively infiltrated the adjacent neural parenchyma. Characteristic perivascular pseudorosettes were observed in all ependymomas; true rosettes were less common. Some tumors had areas of necrosis, mineralization, cholesterol clefts, and/or hemorrhage. This cohort study of feline ependymal tumors includes subependymoma and primary extraventricular ependymoma, variants not previously described in the veterinary literature but well recognized in humans.

Abstract
In the United States, approximately 65,000 people are diagnosed with primary brain tumors each year, with an incidence of 19.3 cases per 100,000 person-years. These numbers represent a wide spectrum of disease, from benign to malignant, and prognosis varies widely based on disease. Treatment of primary brain tumors most often uses a combination of surgery and radiation. However, over the past several generations, technological advancements have significantly altered the treatment paradigm. This article reviews the current role of neurosurgery and radiation therapy in the management of primary brain tumors.

Abstract
A case of anaplastic ependymoma of the cerebral hemisphere in which the histopathological features closely simulated those of glioblastoma is reported. The patient was a 72-year-old woman with a large, well-demarcated tumor in the left temporal lobe. The tumor was totally extirpated, but recurred 18 months later, and the patient died after 4 months. The extirpated tumor was well circumscribed from the surrounding brain tissue and consisted of a sheet-like, dense proliferation of atypical, short spindle or polygonal cells. Extensive geographic necrosis with nuclear pseudopalisading was seen. Although perivascular pseudorosettes were observed in many areas, true ependymal rosettes were absent. Immunohistochemistry for glial fibrillary acidic protein and epithelial membrane antigen and ultrastructural study confirmed the ependymal nature of tumor cells. The histopathological spectrum of anaplastic ependymoma is very wide and reflects the basically dual characteristics of ependymal cells: epithelial and glial phenotypes. The present case indicates that some anaplastic ependymomas strongly express the glial phenotype and also show remarkable anaplastic cytological features, thus closely simulating glioblastoma. The diagnostic criteria for anaplastic ependymoma, and the nosological position of highly anaplastic ependymoma and its possible clinical implications, are briefly discussed.

Abstract
Twenty-seven cases of ependymoma were collected in the French multicentric study dedicated to lateral ventricle tumors. The mean age of patients was 31,5 years. All patients underwent surgery, with complete resection of the tumor in 76% of cases. Histologic examination disclosed 23 grade 2 ependymomas and four grade 3 ependymomas. Postoperative mortality was 7%. Four patients underwent radiotherapy, and five chemotherapy. Local recurrence of the tumor occurred in seven cases, with a mean delay of 48 months. Disseminated disease within the central nervous system was found in only one patient. Median survival in all the 27 patients was 181 months, and median progression-free survival was 106 months. The relevant series of the literature are reviewed in order to precise the prognostic factors of ependymomas and therapeutic strategies.

Abstract
Supratentorial cortical ependymoma is a rare clinical entity where ependymoma occurring in the cortex without any connection to the ventricular system since ependymoma usually arises from the lining of the ventricular system or central canal of spinal cord. There have been 14 such cases reported in the literature.We report the first case of a supratentorial extraaxial cortical anaplastic ependymoma with minimal cortical attachment in a 17-years-old girl, presented with headache and complex partial seizure. Histological features of anaplasia including numerous mitoses, necrosis and high Ki-67 lead to postoperative adjuvant radiation therapy although gross total resection was achieved.

Abstract
We report a case of anaplastic ependymoma with extracranial metastases in a 22-year-old female. The patient originally presented with headaches and dysarthria. Neuroimaging revealed a large solid and cystic right fronto-temporal lesion. It was located completely extraventricularly and a glioblastoma was suspected based on the neuroimaging findings. A gross total resection was achieved. Histopathologic examination revealed an anaplastic ependymoma. The patient was treated with radiotherapy. Approximately 1 year after the initial surgery, the patient presented with metastatic disease to the scalp. At 2 years, an intraparotid metastasis was detected. Subsequent neck dissection revealed positive lymph nodes at several levels. It was followed by radiotherapy to the neck. 5 years after the initial surgery, the patient has residual metastatic disease. The case is discussed and the literature on extraventricular ependymal neoplasms is reviewed.

Abstract
Ependymomas are rare primary central nervous system tumors in adults. They occur most commonly in the spinal cord, where histopathologic evaluation is critical to differentiate the grade I myxopapillary ependymoma from the grade II ependymoma or grade III anaplastic ependymoma. Brain ependymomas are either grade II or III. Treatment for all grades and types includes maximum surgical resection. For myxopapillary ependymoma, complete removal while maintaining capsule integrity may be curative. Some grade II ependymomas may be observed carefully after imaging confirms complete resection, but grade III tumors require adjuvant radiation treatment. Radiation commonly is given to the region of tumor, except in cases in which there is imaging or cerebrospinal fluid evidence of tumor dissemination. Chemotherapy has not been studied extensively, although most reports suggest only modest benefit. Ongoing laboratory studies have uncovered important signal transduction pathways that may be better therapeutic targets, leading to the development of clinical trials using targeted agents.

Abstract
Ependymomas rarely arise from the region of the pituitary fossa, with only four cases previously reported in the literature. We present a complex case of a recurrent ependymoma of the parasellar region which has been difficult to clinically manage due to its tendency to recurrence. Our patient has had four operations over the last 28 years, with external beam radiotherapy, but still has residual tumor and is currently panhypopituitary and with significant visual loss. We believe there is considerable uncertainty as to the optimal management of any future progression, which seems likely, and are currently considering the use of radiosurgery with careful sparing of the optic chiasm, or possibly the chemotherapeutic agent temozolomide. Our case emphasises the recurrent nature of this rare but difficult tumor.

Abstract
A 15-year-old boy presented with an anaplastic supratentorial ependymoma causing massive intratumoral calcification, without contributory medical and family history, and manifesting as persistent headache for 2 months. Physical examination found no neurological deficit except for visual defect in the right lower quadrant, with intact visual acuity. Blood examination showed no abnormalities. Cranial computed tomography revealed a huge calcified mass in the left parietooccipital lobe, with extensive perilesional brain edema. Cranial radiography showed diffuse and symmetrical thinning of the calvarial bone. Magnetic resonance imaging confirmed the tumor as an assembly of medullated masses with extraventricular location, 7 x 6.5 x 6.5 cm in diameter, and appearing as heterogeneous intensity on both T(1)- and T(2)-weighted images with inhomogeneous enhancement except for the central cores. The patient underwent tumor resection. Intraoperative findings revealed that the cortical veins overlying the tumor were reddish and moderately engorged. The hypervascular tumor, entirely extraventricular in location, was totally resected without neurological deterioration. Histological examination revealed that the tumor was highly cellular with hyperchromatic nuclei and cell atypia. Necrosis, mitotic figures, and perivascular pseudorosette formations were frequently seen. Immunohistochemical study showed positive staining for glial fibrillary acidic protein, S-100 protein, vimentin, and epithelial membrane antigen, but negative for synaptophysin. The MIB-1 labeling index was 26.5%. The findings were compatible with anaplastic ependymoma (World Health Organization classification grade 3). Ependymoma should be included in the differential diagnosis of a supratentorially located, extraventricular mass with massive intratumoral calcification.

Abstract
BACKGROUND To the authors' knowledge, there currently is no standard therapy for platinum-resistant ependymoma; hence, a need exists for new therapies. In the current study, a retrospective evaluation of temozolomide (TMZ) in adults with recurrent, supratentorial, platinum-refractory, World Health Organization grade 2 ependymoma was performed, with an objective of determining 6-month progression-free survival (PFS). METHODS A total of 25 patients, ages 28 to 63 years, with recurrent ependymoma were treated. All patients had previously been treated with surgery, radiotherapy, and platinum-based chemotherapy (cisplatin in 15 patients and carboplatin in 10 patients). Nine patients underwent repeat surgery. Patients were treated at the time of second recurrence with TMZ (5 consecutive days), once every 4 weeks, which was defined as a single cycle. Neurologic evaluation was performed every 4 weeks and neuroradiographic assessment every 8 weeks. RESULTS A total of 68 cycles of TMZ (median, 2 cycles; range, 1-6 cycles) was administered. TMZ-related toxicity included leukopenia (7 patients; 1 with grade 3 [grade was determine according to National Cancer Institute Common Toxicity Criteria [version 3.0]), constipation (6 patients; none with grade 3), fatigue (5 patients; none with grade 3), anemia (2; none with grade 3), thrombocytopenia (2; none with grade 3), and deep vein thrombosis (2; none with grade 3). One patient (4%) demonstrated a partial radiographic response, 9 (36%) had stable disease, and 15 (60%) developed progressive disease after 2 cycles of TMZ. Time to tumor progression ranged from 1 to 7 months (median, 2 months). Survival ranged from 2 to 8 months (median, 3 months). The 6-month and 12-month PFS were 2% and 0%, respectively. CONCLUSIONS TMZ in this dose schedule demonstrated little efficacy in a cohort of adults with recurrent, intracranial, platinum-refractory ependymoma.

Abstract
INTRODUCTION Supratentorial ependymomas are rare neoplasms accounting for just ten to 15 new cases in the UK per year. This article discusses the surgical management of these tumours. MATERIALS AND METHODS We present our experience over the past 12 years looking, in particular, at the location, histological grading, postoperative complications, survival and progression-free survival. A literature review of publications discussing the surgical management of ependymoma over the past 10 years is then presented. RESULTS The data shows that complete surgical resection confers a significant survival advantage. There appears to be conflicting data with respect to prognosis when comparing supratentorial to infratentorial ependymoma. CONCLUSION The authors suggest complete excision and advocate, where appropriate, the use of pre and intra-operative functional mapping and second-look surgery. The trade off neurological deficit in the pursuit of complete surgical excision in some instances should be considered.

Abstract
Ependymomas represent a heterogeneous group of glial tumors whose biological behavior depends on various histological, molecular, and clinical variables. The scope of this chapter is to review the clinical and histo-logical features as well as the molecular genetics of ependymomas with special emphasis on their influence on tumor recurrence and prognosis. Furthermore, potential molecular targets for therapy are outlined.

Abstract
Overexpression of Aurora B kinase, which regulates cell progression through mitosis and cytokinesis, has been shown to be associated with higher-grade tumors and shortened survival in astrocytomas. Aurora B expression was evaluated by immunohistochemistry in 32 ependymomas, 10 anaplastic ependymomas, 16 myxopapillary ependymomas, and 9 subependymomas. Aurora B expression was identified in 20 (62.5%) ependymomas, 5 (50%) anaplastic ependymomas, 1 (6.3%) myxopapillary ependymoma, and no subependymomas. The association between Aurora B expression and World Health Organization grade II/III tumors was statistically significant (P<0.0001). There was no difference in the level of Aurora B expression between ependymomas and anaplastic ependymomas. Aurora B expression was not associated with patient age, sex, tumor location, tumor recurrence, or death from tumor. In contrast to astrocytomas, elevated Aurora B expression in higher-grade ependymomas does not seem to correlate with clinical course, although it may be a potential target of Aurora kinase inhibitors.

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
A broad spectrum of neoplasms affects the sellar region. Among these, gliomas are rare, most being tumors of pituicytes such as granular cell tumor and pituicytoma. Only 4 ependymomas of the human sellar region have been reported to date and all have had classic histologic features. Herein, we describe the clinicopathologic features of a sellar, low-grade ependymoma with unusual histology, but classic ultrastructural features, occurring in an elderly patient and thus expanding the spectrum of reported cases. The literature is reviewed and concepts of histogenesis are explored, particularly an origin in "ependymal pituicytes." The concept that sellar ependymoma is pituicyte-derived is explored.
