The role of … Methods Preoperative MR images of 30 CNs and another 68 intraventricular non-CN tumours were analysed by one experienced neuroradiologist retrospectively to identify previously reported features and new features of CN. 11. We also assessed the tumour NADC values. It accounts approximately 0.25–0.5% of intracranial tumors. Immunohistochemistry confirms the purely neuronal origin by positivity to neuronal markers such as 11: Importantly, IDH mutations and 1p19q co-deletion are absent (characteristic of oligodendrogliomas). The vast majority of central neurocytomas are located entirely within the ventricles. [Neuroimaging features of intraventricular neurocytoma]. 1991;156 (6): 1311-3.

Syn : Neurocytoma. However, this was upgraded in 1993 to WHO grade II (and remains so in the 2016 version) as it was recognized that at least some of these tumors exhibited more aggressive behavior 10. In this case, we notice a dilatation of both lateral ventricles, but with no transependymal CSF permeation, which indicates chronic hydrocephalus and slow-growing mass. The first report resulted in increased recognition of the tumor, and a number of reports have since been published in the literature. In this report, we describe a very rare case of tetraventricular CN with imaging-pathologic correlation, and discuss their atypical features in a location together with treatment options. (2009) Magnetic resonance imaging. Bookmarks (0) Brain. 6. A relatively short clinical course, typically only a few months, is most common. The authors review the literature. NIH Although structural imaging findings of CNC are typical, they are not specific. Materials and methods: Six patients were imaged using non-enhanced and contrast-enhanced magnetic resonance imaging (MRI); three of them were also examined using non-enhanced computed tomography (CT). On CT, diffuse and diverse calcifications were observed in nine cases and cysts varying in sizes were revealed in all. Central Neurocytoma Cystic regions are frequently present, especially in larger tumors. 13. ... Central Neurocytoma. On DWI, the tumours had heterogeneous hyperintense appearances and the tumour NADC values were 0.93±0.21.On MRS, elevated Cho and Gly peaks and reduced Cr and NAA peaks were obtained. CN is a benign tu-mor of the central nervous system that is classified as a grade II tumor by the World Health Organization (WHO) [2,3]. ATYPICAL CENTRAL NEUROCYTOMA: REPORT OF TWO CASES. Materials and methods: Clinical and imaging findings of 18 patients (nine female and nine male; age range, 18-37 years old (27.8±5.7)) with histopathological diagnosis of CN were evaluated retrospectively. Objectives: zhangbo0616@sohu.com Central neurocytoma (CNC) is an uncommon benign tumor of the central nervous system (CNS) occurring in adults and is more likely to be located in the region of the foramina of Monra. Clipboard, Search History, and several other advanced features are temporarily unavailable. Ganglioneurocytoma is a variant, usually of extraventricular neurocytomas, demonstrating a distinct ganglion cells component 6,11,12. This is a postoperative post shunting case of neurocytomas, note the intraventricular nature of tumour, calcification and operative pneumocephalus. It usually occurs in young adults with no sex predilection and constitutes approximately 0.1-0.5 % of all intracranial tumours [1-2]. Objectives: To evaluate clinical findings and radiological characteristics of central neurocytoma (CN) in 18 patients and magnetic resonance spectroscopy (MRS) features in one additional case. Other differentials for an intraventricular mass including an ependymoma or intraventricular metastasis are felt less likely given the imaging appearances. Most of them occur as an exophytic, well circumscribed, globular mass that protrudes into the ventricles. Louis DN, Ohgaki H, Wiestler OD, Cavenee WK "WHO Classification of Tumours of the Central Nervous System. imaging. We report a case of neurocytoma located in the fourth ventricle and extended into the third ventricle. A number of cases have been reported after this tumor was first described by Hassoun et al in 1982. Intraventricular tumor with imaging features favoring a central neurocytoma (somewhat atypical in a patient of this age) or subependymoma. Central neurocytoma (CN) is an uncommon brain tumor arising primarily in the lateral ventricular near the foramen of Monro and approximately accounting for 0.1-0.5% of all primary tumors of the central nervous system.

Shin JH, Lee HK, Khang SK et-al. The distinct radiological features such as: (1) diffuse and diverse calcifications on CT images; (2) clusters of cysts of varying sizes resulting in the "swiss cheese/soap bubble" appearance on T2WI and heterogeneous moderate enhancement on MR images; (3) the incorporation of the septum pellucidum in bilateral tumours and abutting of the septum pellucidum in unilateral tumours together with the attachment of the wall of the ventricles can help in the diagnosis of preoperative central neurocytoma. The initial description classified them as WHO grade I lesions. Central neurocytomas demonstrate neuronal differentiation and histologically appear similar to oligodendrogliomas which, historically, resulted in many tumors erroneously categorized. The first report resulted in increased recognition of the tumor, and a number of reports have since been published in the literature. Cases of CSF dissemination have been reported, but are rare 10. Most CNs are benign, well-differentiated tumors that exhibit neuronal differentiation and have an indolent clinical course after their initial presentation as obstructive hydrocephalus or visual disturbance. 18 (6): 1175-8.

Classic MRI and CT findings of central neurocytoma, which was histologically proven. Most of the patients present with symptoms of increased intracranial pressure secondary to the obstructive hydrocephalus [1, 2, 4]. Clusters of cysts gave the tumours a "swiss cheese/soap bubble" inhomogeneous hyperintense appearance on T2WI and FLAIR images. This image also shows an entrapped right frontal horn indicated by incomplete suppression of cerebrospinal fluid. Case Discussion.

Complete surgical resection is usually curative (5 years survival 81%). There is no reported gender predilection 10. The prognosis of central neurocytoma is favorable in most of the cases; however malignant course of this tumor has been established very uncommonly [9, 10]. Seventy-two percent of patients with central neurocytoma are diagnosed at the age of 20–40 years old; 12 the tumour is exceptional in the first decade and after 50 years. Author information: (1)Department of Radiology, Huashan Hospital, Fudan University, Shanghai 200040, People's Republic of China. link. When only incomplete resection possible or extraventricular extension is present, then adjuvant radiotherapy (and sometimes chemotherapy) are added, although their benefit is not well established. 1. Emphasis is placed on radiological and pathological features not previously described. 2008;29 (1): 190-1. On MRI, the solid parts of the tumours were mainly hypo- to isointense on all T1WI and isointense to grey matter on T2WI.
