Extensive craniospinal dissemination of extraventricular neurocytoma: A case report and review of literature

Interdisciplinary Neurosurgery, 2018
Central neurocytomas (CNCs) are benign intraventricular neoplasms seen in children and young adults. Rarely, neoplasms that are similar in histopathological appearance arise in the brain parenchyma and are termed as extra-ventricular neurocytoma (EVNC ...

Molecular Landscape of Pediatric Low‐Grade Gliomas: Insights From RNA‐NGS and Bioinformatic Analysis

Genes, Chromosomes and Cancer, Volume 64, Issue 10, October 2025.
ABSTRACT Pediatric low‐grade gliomas (pLGG) are the most common group of childhood brain tumors. Genetic alterations in the RAS–RAF–mitogen‐activated protein kinase (MAPK) pathway are the molecular drivers in the vast majority of pLGG. A large proportion of pediatric pLGG are characterized by the presence of fusion genes.

Tumor‐related epilepsy in glioma: A multidisciplinary overview

Epilepsia, Volume 66, Issue 10, Page 3621-3641, October 2025.
Abstract Seizures are a common and challenging symptom in brain tumors, affecting approximately 60% of patients. Tumor‐related epilepsy (TRE) in glioma patients requires personalized and dynamic management in a multidisciplinary environment, especially for its intricate pathophysiology and unpredictable disease evolution. This investigation provides an

MRI findings in six dogs with ependymoma of the brain and spinal cord

Veterinary Radiology &Ultrasound, Volume 66, Issue 1, January 2025.
Abstract There are few published descriptions of the MRI appearance of canine intracranial or spinal cord ependymoma. In this multicenter, retrospective, secondary analysis, case series study, three veterinary radiologists independently reviewed and recorded imaging characteristics of MRI studies in six dogs with histopathologically confirmed ...

Phenotypic and epigenetic heterogeneity in FGFR2‐fused glial and glioneuronal tumours

Neuropathology and Applied Neurobiology, Volume 50, Issue 6, December 2024.
FGFR2‐fused brain tumours might represent rather a spectrum of paediatric diffuse low‐grade glioma, glioneuronal and neuronal tumours overlapping PLNTY and ganglioglioma than a unique tumour type.Although the differences are very slight in terms of histopathology or epigenetics, neuroradiology identifies two distinct radiological patterns suggesting ...

Cerebellar Extraventricular Neurocytoma With Spinal Seeding

Marmara Medical Journal, 2011
Central neurocytomas are typically located in lateral or third ventricles. Here, we report a case of neurocytoma located in the middle cerebellar peduncle. A 36-year-old male patient presented with symptoms of ataxic gait and urinary incontinence for one month.

Cytopathology of glioneuronal and neuronal tumours with histological correlations

Cytopathology, Volume 35, Issue 5, Page 545-555, September 2024.
Abstract Glioneuronal and neuronal tumours constitute a diverse group of tumours that feature neuronal differentiation. In mixed glioneuronal tumours, a glial component is present in addition to the neuronal component. With a few exceptions (eg diffuse leptomeningeal glioneuronal tumour) they are well‐circumscribed and slow‐growing tumours, which is ...

Cross-Species Genomics Reveals Oncogenic Dependencies in ZFTA/C11orf95 Fusion–Positive Supratentorial Ependymomas [PDF]

, 2021
Molecular groups of supratentorial ependymomas comprise tumors with ZFTA-RELA or YAP1-involving fusions and fusion-negative subependymoma. However, occasionally supratentorial ependymomas cannot be readily assigned to any of these groups due to lack of ...
