Extra ventricular Neurocytoma is known but rare. Typical locations include 4: Central neurocytomas are usually friable grey-colored tumors, sometimes demonstrating areas of calcification and hemorrhage 11. Central neurocytomas have a well-delineated, smooth or lobulated margin and are moderately vascular. 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.

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). Complete surgical resection is usually curative (5 years survival 81%). Koral K, Kedzierski RM, Gimi B et-al. 1991;156 (6): 1311-3. The tumor is typically supratentorial, located in the lateral ventricles adjacent to the foramen of Monro. 2008;29 (1): 190-1. It usually occurs in young adults with no sex predilection and constitutes approximately 0.1-0.5 % of all intracranial tumours [1-2]. 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]. Clusters of cysts gave the tumours a "swiss cheese/soap bubble" inhomogeneous hyperintense appearance on T2WI and FLAIR images. Intraventricular tumor with imaging features favoring a central neurocytoma (somewhat atypical in a patient of this age) or subependymoma. Eight patients underwent CT and eight had MR imaging.

Clin Radiol. 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). 10. Three tumours continued towards the foramen of Monro and one to the third ventricle. Central neurocytoma is a recently described, rare primary brain tumor of neuronal origin, which is characterized by predominant occurrence in the young adults, exclusive later- al ventricular location, and oligodendroglioma-like histolo- gy (1,8, 12-14, 17).

The maximum diameter of the CNs varied from 3.4 to 9.2 cm (5.2±1.5 cm). The interesting point about intratumoral hemorrhage of central neurocytoma is that it may not appear on CT images, and may only be discernible on MR imaging [8].

Central neurocytoma presenting with intraventricular hemorrhage: case report and review of literature. There is no reported gender predilection 10. We also assessed the tumour NADC values. 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.  |  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. The first report resulted in increased recognition of the tumor, and a number of reports have since been published in the literature. ... CT scan and magnetic resonance imaging (MRI) revealed temporal bone tumor extending right orbital bone and diffuse leptomeningeal thickening. Studies comparing intraventricular oligodendroglioma (IVO) and central neurocytoma (CN) in terms of their clinical, radiological and pathological features are scarce. No large feeding arteries are usually seen. 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. [1] who studied two patients with intraven - tricular tumors using electron microscopy. RTU-26.

Histologic and immunopathologic examination showed low-grade characteristics with neuronal differentiation (synaptophysin and neuronal nuclear antigen were positive), these findings indicating central neurocytoma. 12. Typically, central neurocytomas present with symptoms of increased intracranial pressure, headaches being most frequent, or seizures (especially tumors with extraventricular extension). On CT, diffuse and diverse calcifications were observed in nine cases and cysts varying in sizes were revealed in all. We present the unusual case of a fourth ventricular central neurocytoma in a 70-year-old female presenting with imbalance and headaches, with an enhancing fourth ventricular mass on imaging. Epub 2016 Apr 23. MRS was also obtained for one additional case. Diagnosis. Central neurocytoma is a rare brain tumour composed of uniform round cells with neuronal differentiation. Central neurocytomas are WHO grade II neuroepithelial intraventricular tumors with fairly characteristic imaging features, appearing as heterogeneous masses of variable size and enhancement within the lateral ventricle, typically attached to the septum pellucidum.  |  Central neurocytomas are rare tumors, typically found in the third ventricle.

Central Neurocytoma Extraventricular neurocytomas (previously known as cerebral neurocytomas) are distinctly uncommon and discussed in a separate article. Koeller KK, Sandberg GD. Most of the patients present with symptoms of increased intracranial pressure secondary to the obstructive hydrocephalus [1, 2, 4]. 2. Two radiologists read the images retrospectively. A relatively short clinical course, typically only a few months, is most common. 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.
