Abstract
Supratentorial cortical ependymoma is an extremely rare malignancy in the pediatric population, especially in very young age groups. Most of the reported cases present with dramatic neurological symptoms like seizures and sudden onset hemiplegia. We hereby report a case of anaplastic supra-cortical ependymoma in a 13-month-old male child, with subtle seizures for four weeks. The child, who was brought for non-neurological complaints to the outpatient clinic, was found to have abnormal staring episodes. An electroencephalogram showed focal epilepsy and an MRI brain showed a large intra-axial lesion in the left frontal area. The child underwent gross total resection of the lesion and histopathology revealed WHO grade 3 cortical ependymoma.

Abstract
BACKGROUND AND PURPOSE The 5th edition of the World Health Organization Classification of CNS tumors defines the CNS neuroblastoma FOXR2 in the group of embryonal tumors. Published clinical outcomes tend to suggest a favorable outcome after resection, craniospinal irradiation, and chemotherapy. This multicenter study aimed to describe imaging features of CNS neuroblastoma-FOXR2, which have been poorly characterized thus far. MATERIALS AND METHODS On the basis of a previously published cohort of tumors molecularly classified as CNS neuroblastoma-FOXR2, patients with available imaging data were identified. The imaging features on preoperative MR imaging and CT data were recorded by 8 experienced pediatric neuroradiologists in consensus review meetings. RESULTS Twenty-five patients were evaluated (13 girls; median age, 4.5 years). The tumors were often large (mean, 115 [ SD, 83] mL), showed no (24%) or limited (60%) perilesional edema, demonstrated heterogeneous enhancement, were often calcified and/or hemorrhagic (52%), were always T2WI-hyperintense to GM, and commonly had cystic and/or necrotic components (96%). The mean ADC values were low (687.8 [SD 136.3] × 10-6 mm2/s). The tumors were always supratentorial. Metastases were infrequent (20%) and, when present, were of nodular appearance and leptomeningeal. CONCLUSIONS In our cohort, CNS neuroblastoma FOXR2 tumors showed imaging features suggesting high-grade malignancy and, at the same time, showed characteristics of less aggressive behavior. There are important differential diagnoses, but the results of this study may assist in considering this diagnosis preoperatively.

Supratentorial extra-axial RELA fusion-positive ependymoma misdiagnosed as meningioma by intraoperative histological and cytological examinations: a case report. J Med Case Rep 2022; 16:312. [PMID: 35986385 PMCID: PMC9392293 DOI: 10.1186/s13256-022-03555-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 08/02/2022] [Indexed: 11/12/2022] Open
Abstract
Background Dura-attached supratentorial extra-axial ependymoma is a very rare type of tumor, with only nine reported cases. Preoperative diagnosis of dura-attached supratentorial extra-axial ependymoma is difficult and often radiologically misdiagnosed as a meningioma. We report a case of dura-attached supratentorial extra-axial ependymoma that was misdiagnosed using intraoperative histological and cytological examinations. Case presentation A 26-year-old Japanese man with headache and nausea was referred to our medical facility. Magnetic resonance imaging revealed a cystic mass of 70 × 53 × 57 mm in the left temporoparietal lobe. A peritumoral band with hyperintensity on T2-weighted imaging was observed at the periphery of the lesion, suggesting an extra-axial lesion with no apparent connection to the ventricle. A dural tail sign was also noted on the gadolinium-enhanced T1-weighted image. Preoperative clinical diagnosis was meningioma. Proliferated tumor cells in sheets with intermingled branching vessels were observed in the frozen tissue. Perivascular rosettes were inconspicuous, and the tumor cells had rhabdoid cytoplasm. The tumor was intraoperatively diagnosed as a meningioma, suspected to be a rhabdoid meningioma. Perivascular rosettes were evident in the formalin-fixed paraffin-embedded tissues, suggesting ependymoma. The tumor cells had eosinophilic cytoplasm without a rhabdoid appearance. Anaplastic features, such as high tumor cellularity, increased mitotic activity, microvascular proliferation, and necrosis, were observed. Ependymal differentiation was confirmed on the basis of ultrastructural analysis. Molecular analysis detected C11orf95-RELA fusion gene. The final diagnosis was RELA fusion-positive ependymoma, World Health Organization grade III. Conclusion Owing to its unusual location, dura-attached supratentorial extra-axial ependymomas are frequently misdiagnosed as meningiomas. Neuropathologists should take great precaution in intraoperatively diagnosing this rare subtype of ependymoma to avoid misdiagnosis of the lesion as other common dura-attached tumors.

Rare Tumors 2022; 14:20363613221112432. [PMID: 35836750 PMCID: PMC9274435 DOI: 10.1177/20363613221112432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Accepted: 06/10/2022] [Indexed: 11/26/2022] Open
Abstract
Cortical ependymomas are currently not considered a subgroup of supratentorial
ependymomas; however, there is a growing body of literature investigating the
natural history of these lesions compared to supratentorial ependymomas. We
performed a systematic literature review of cortical ependymomas with a focus on
the natural history, clinical characteristics, and clinical outcomes of these
lesions as compared to supratentorial ependymomas. Our search revealed 153
unique cases of cortical ependymomas. The mean age on presentation was
21.2 years. Males and females comprised 58.8% (90/153) and 41.2% (63/153) of
cases, respectively. The most common presenting symptom was seizure activity
occurring in 44.4% of the cohort (68/153). The recently recognized
C11orf95-RELA fusion was identified in 13.7% of the cohort
(21/153) and 95.5% of cases (21/22) reporting molecular characterization. World
Health Organization grades 2 and 3 were reported in 52.3% (79/151) and 47.7%
(72/151) of cases, respectively. The frontal lobe was involved in the majority
of cases (54.9%, 84/153). Gross total resection was achieved in 80.4% of cases
(123/153). Tumor recurrence was identified in 27.7% of cases (39/141). Mean
clinical follow-up was 41.3 months. Mean overall survival of patients who
expired was 27.4 months whereas mean progression-free survival was 15.0 months.
Comparatively, cortical ependymomas with
C11orf95-RELA fusions and supratentorial
ependymomas with C11orf95 RELA fusions exhibited differing
clinical outcomes. Further studies with larger sample sizes are necessary to
investigate the significance of RELA fusions on survival in
cortical ependymomas and to determine whether cortical ependymomas with
C11orf95-RELA fusions should be classified
as a distinct entity.

ZFTA-fusion in supratentorial ependymomas: low prevalence in South Asians and no correlation with survival. World Neurosurg 2022; 164:e82-e90. [PMID: 35378317 DOI: 10.1016/j.wneu.2022.03.133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 03/28/2022] [Accepted: 03/29/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND - Supratentorial ependymomas (STEs) are an aggressive group of ependymoma, topographically distinct from their posterior fossa and spinal counterparts. ZFTA fusion-positive cases have been reported to account for the majority of STEs, although data on its association with poorer outcomes is inconsistent. MATERIALS AND METHODS - We assessed the prevalence of the ZFTA-fusion by RT PCR and FISH in a cohort of 61 patients (68 samples) with STE. Our primary outcome was to determine the role of the ZFTA-fusion on progression-free and overall survival of patients with STE. Our secondary objectives were to assess the impact of ZFTA-fusion on NF-kB pathway signalling via surrogate markers of this pathway, namely COX-2, CCND1 and L1CAM. RESULTS - ZFTA-fusion was noted in 21.3% of STEs in our cohort. The presence of this rearrangement did not significantly impact the PFS or OS of patients with STEs and was not associated with upregulation of markers of the NF-kB pathway. Only gross total resection was significantly associated with better progression-free survival. CONCLUSION - In contradiction to prior reports from across the world, the ZFTA-fusion is far less prevalent among our population. It does not appear to drive NF-kB signaling or significantly affect outcomes. Gross total resection (GTR) must be attempted in all cases of STE and adjuvant radiation and/or chemotherapy employed when GTR is not achieved.

Abstract
Purpose/Objectives The debate on whether radiotherapy (RT) is an essential part of primary treatment in patients with grade II ependymoma (G2E) is still ongoing, and this study aimed to evaluate its role. Materials/Methods A retrospective analysis of all the consecutive patients treated due to G2E in years 1985–2019 was performed. The group consisted of 116 patients with a small predominance of woman (55% vs. 45%) and the location of the tumor in the brain (58% vs. 42%). All had surgery as the primary treatment with 47% R0 resection. Radical RT was applied in 81 patients. In majority of cases (91%), patients received local irradiation. Results Median follow-up was 65 months, and during that time, 17 patients died. Five- and 10-year overall survival (OS) of the whole group was 87% and 83%. Radical surgery (R0 vs. R1/2) improved OS (p = 0.004), but the difference was observed only in patients with brain lesions (p = 0.01). Five- and 10-year progression-free survival (PFS) was 68% and 51%, respectively. Looking at the treatment of recurrence, those who received RT as a part of the treatment of the recurrent tumor had better OS (p = 0.048)—5- and 10-year OS of 85% and 78% vs. 66% and 57%. In the multivariate analysis, radical surgery (R0 vs. R1/2) and the use of RT in the primary treatment improved PFS (p = 0.006 and 0.007). Based on the location of the tumor, the positive influence of RT on PFS was observed only in the case of patients with brain tumors (p = 0.01). Also, comparing R1/2 surgery with R0 resection—the benefit of RT was only observed in R1/2 group (0.02). Conclusions RT in the case of patients with G2E is a valuable treatment of the recurrent disease. Patients with brain lesions after nonradical surgery might benefit from the local irradiation in terms of PFS.

Abstract
A 25-year-old female presented with a generalized tonic-clonic seizure. She had no previous history of seizures. A brain magnetic resonance imaging scan revealed a solitary enhancing mass in the right fronto-parietal cortex. During surgery, the mass was noted to be pure cortical with no connection to the ventricular lining. The tumor was completely resected. After surgery, the patient had no further seizures. The biopsy result showed a supratentorial ependymoma, which was C11orf95-RELA-fusionpositive.
