The importance of staged surgery for giant atypical central neurocytoma

Acta Neurologica Belgica, 2020
The aim of this article is to discuss the importance of staged surgeries when approaching atypical central neurocytoma in children. Also, we show the preoperative embolization of the lesion as a maneuver to reduce the intraoperative bleeding. Central neurocytomas represent less than 0.5% of all intracranial tumors, and atypical central neurocytomas ...

Extraventricular neurocytoma with atypical features and ganglionic differentiation

Journal of Clinical Neuroscience, 2010
Extraventricular neurocytoma (EVN) is an unusual variant of central neurocytoma located outside the ventricular system. Both tumours share a similar histology characterised by monotonous populations of round-to-oval cells with scanty cytoplasm separated by neuropil and branching capillaries. We report an EVN arising from the right frontal lobe near the

Atypical Extraventricular Neurocytoma: Imaging Findings of Disregarded Diagnosis

World Neurosurgery, 2019
Extraventricular neurocytoma (EVN) is an exceedingly rare brain tumor. The radiologic and histologic features of EVN are insidious, and only a few reports and clinical cases describe the characteristics of the tumor, which may show different presentations. We report a case of atypical EVN in a 23-year-old man; Computed Tomography and Magnetic Resonance

Gamma knife radiosurgery of recurrent atypical neurocytoma

Strahlentherapie und Onkologie, 2012
The goal of this work was to demonstrate the efficacy of stereotactic gamma knife radiosurgery (GKRS) for the treatment of neurocytoma by means of a case report and a comprehensive literature review.A locally recurrent atypical neurocytoma in the area of the left third ventricle thalamic wall occurring 7 years after primary microsurgical resection in a

Atypical central neurocytoma: a case report

Pathology, 2012
Central neurocytomas are rare benign tumours of the central nervous system, first described by Hassoun et al . in 1982. Typically patients with central neurocytomas have a favourable prognosis, but some subsets of this tumour are associated with a more aggressive clinical course.

Dose–effect relationship for radiotherapy after incomplete resection of atypical neurocytomas

Radiotherapy and Oncology, 2005
Neurocytomas with atypical histology or high proliferation activity are named atypical. All reported cases were reviewed. After incomplete resection, radiotherapy improved local-control (P54 Gy were associated with better 5-year local control (84% versus 55%, P=0.05) and 5-year-survival (84% versus 65%, P=0.18) than doses < or =54 Gy.

Central neurocytoma: typical magnetic resonance spectroscopy findings and atypical ventricular dissemination

Magnetic Resonance Imaging, 2008
Central neurocytomas (CNCs) are rare neuronal tumors that have a favorable prognosis and lower rate of recurrence compared with other intraventricular neoplasms. Although it may be difficult to distinguish CNC on conventional neuroimaging, typical MR spectroscopy (MRS) features have been reported.

Atypical Suprasellar Neurocytoma in a 31-Month-Old Child: A Case Report

Journal of Pediatric Neurology, 2017
AbstractWe report a case of a 31-month-old girl with visual impairment. Magnetic resonance imaging showed a large cystic lesion with a mural nodule in the suprasellar region. Biopsy was performed, and histopathological examination demonstrated an atypical extraventricular neurocytoma (EVN).

ATYPICAL PAEDIATRIC EXTRA VENTRICULAR NEUROCYTOMA– A RARE CASE REPORT

PARIPEX INDIAN JOURNAL OF RESEARCH
Central neurocytoma (CN) and extra ventricular neurocytoma (EVN) are rare intracranial tumors. Central neurocytomas are well-differentiated, intraventricular lesions mainly seen in adults. Similar tumors may develop in the brain parenchyma or spinal cord referred to as extra ventricular neurocytomas. Here we are reporting a case of 10-year-old boy with

Congenital extraventricular neurocytoma with atypical features in a 3-day-old neonate

Child's Nervous System
Extraventricular neurocytoma (EVN) is a rare neuronal tumor with a marked tendency towards ganglionic or glial differentiation. Although EVN commonly occurs in young adults, congenital cases are extremely rare, and standardized therapeutic strategies remain undetermined.
