Coronal drawing depicts a central neurocytoma within the body of the left lateral ventricle. Central neurocytoma (CN) was originally described by Hassoun et al. 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). Tonn J, Westphal M, Rutka JT. 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. Case report. Three tumours continued towards the foramen of Monro and one to the third ventricle. Clin Radiol. 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. Typical locations include 4: Central neurocytomas are usually friable grey-colored tumors, sometimes demonstrating areas of calcification and hemorrhage 11. [1] who studied two patients with intraven - tricular tumors using electron microscopy. Central Neurocytoma-CT Imaging 12 years ago 3D CT, Brain tumour, Neurocytoma, Teleradiology Imaging of central neurocytoma is usually characteristic. [1] who studied two patients with intraven - tricular tumors using electron microscopy. Contrast enhancement is usually mild to moderate. Most of the patients present with symptoms of increased intracranial pressure secondary to the obstructive hydrocephalus [1, 2, 4]. Acta Neurol Belg. Emphasis is placed on radiological and pathological features not previously described. Figure 1: histology - "salt and pepper" appearance, Intraventricular meningioma - third ventricle, typically iso to somewhat hyperintense compared to brain, numerous cystic areas (bubbly appearance), many of which completely attenuate on FLAIR, calcification is common, typically punctate, hemorrhage (especially in larger tumors) is common, uncommonly results in ventricular hemorrhage, diffusion restriction of the solid component, glycine peak (3.55ppm) has also been reported, supratentorial tumors (esp in children) often have a significant extraventricular (parenchymal) component, may have ependymoma components and look very similar, typically show intense contrast enhancement, this is especially difficult in cases where there is a parenchymal component as histologically the tumors are very similar. The vast majority of central neurocytomas are located entirely within the ventricles. Parker DR. Neuroradiology case of the day. 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]. Would you like email updates of new search results?

Medical illustration by James A. Cooper, MD, Radiology Medical Group, San Diego, California ([email protected], www.cooperspective.com). It usually occurs in young adults with no sex predilection and constitutes approximately 0.1-0.5 % of all intracranial tumours [1-2]. Also rare, is a sudden presentation due to intraventricular hemorrhage 7. Complete surgical resection is usually curative (5 years survival 81%). Two radiologists read the images retrospectively. 2016 Jul;146:18-23. doi: 10.1016/j.clineuro.2016.04.012. Both MR and CT images were acquired for other two patients. 22 (5): 1177-89. Central neurocytoma: proton MR spectroscopy and diffusion weighted MR imaging findings. Eight lesions were unilateral ventricle (44%) and ten were located in both lateral ventricles. Central neurocytomas are usually hyperattenuating compared to white matter. We also assessed the tumour NADC values. They are typically seen in young patients and generally have a good prognosis provided a complete resection can be achieved. Figure 1: (Top Left) This large central neurocytoma demonstrates its typically cystic feature on axial FLAIR. Clinical symptoms at the time of presentation were headaches (n=11), dizziness (n=6), visual disturbances (n=2), etc. Radiology Cases and Radiology Case Reports.

A 36-year old Malay lady presented with an 8-month history of frontal headache which was throbbing in nature. Diagnosis. Surgery is the standard treatment for central neurocytomas. Pathology-based Diagnoses. Copyright © 2012 Elsevier Masson SAS. Central neurocytoma is a rare intracranial neoplasm arise most commonly in the lateral ventricles particularly in the frontal horns near the foramen of Monro with a characteristic attachment to the septum pellucidum. Radiology. ... [8-10]. The mass is attached to the septum pellucidum but does not extend outside the ventricle. We report a case of neurocytoma located in the fourth ventricle and extended into the third ventricle. The cells are typically uniform and round with a salt and pepper finely speckled chromatin 11. Ganglioneurocytoma is a variant, usually of extraventricular neurocytomas, demonstrating a distinct ganglion cells component 6,11,12. 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. (2009) Magnetic resonance imaging. Sunday, 1 January 2012. Central neurocytoma: proton MR spectroscopy and diffusion weighted MR imaging findings. Unable to process the form.

Tortori-Donati P, Fondelli MP, Rossi A et-al. 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). MRS was also obtained for one additional case. The maximum diameter of the CNs varied from 3.4 to 9.2 cm (5.2±1.5 cm). Case Discussion. Central Neurocytoma 1. Contrast enhancement is usually mild to moderate. CASE REPORT: PLEOMORPHIC XANTHOASTROCYTOMA (PXA) IN A 9YO WITH TP53 MUTATION. Extraventricular neurocytomas (previously known as cerebral neurocytomas) are distinctly uncommon and discussed in a separate article. Central neurocytomas are rare tumors, typically found in the third ventricle. Central neurocytomas have a well-delineated, smooth or lobulated margin and are moderately vascular.

Intraventricular tumor with imaging features favoring a central neurocytoma (somewhat atypical in a patient of this age) or subependymoma. Two radiologists read the images retrospectively. 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].  |  Kocaoglu M, 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. Heterogeneous moderate enhancement (5/8) was present on T1 postcontrast images. ... CT scan and magnetic resonance imaging (MRI) revealed temporal bone tumor extending right orbital bone and diffuse leptomeningeal thickening. Cystic regions are frequently present, especially in larger tumors.
