Two radiologists read the images retrospectively. Central neurocytoma is a hypervascular tumor but spontaneous intratumoral bleeding is very uncommon [5]. 1. Louis DN, Ohgaki H, Wiestler OD, Cavenee WK "WHO Classification of Tumours of the Central Nervous System. Epub 2018 Apr 30. They also demonstrate areas of variable architecture that are reminiscent of other tumors, including oligodendrogliomas, pineocytomas and neuroendocrine tumors 11. 18 (6): 1175-8. These lesions may obstruct spinal fluid flow and/or put pressure on surrounding structures, causing symptoms including headaches and confusion. Radiology Cases and Radiology Case Reports. ... [8-10]. It accounts approximately 0.25–0.5% of intracranial tumors. Familial multiple cavernous malformation, caused by mutation in Krev interaction trapped protein 1 gene (KRIT-1) A surgical biopsy of the lesion was taken. Oncology of CNS Tumors. Central neurocytomas demonstrate neuronal differentiation and histologically appear similar to oligodendrogliomas which, historically, resulted in many tumors erroneously categorized. 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]. An intra ventricular neuro epithelial tumour. Clusters of cysts gave the tumours a "swiss cheese/soap bubble" inhomogeneous hyperintense appearance on T2WI and FLAIR images. 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. [1] who studied two patients with intraven - tricular tumors using electron microscopy. 5. Most of the patients present with symptoms of increased intracranial pressure secondary to the obstructive hydrocephalus [1, 2, 4].

Contrast enhancement is usually mild to moderate. 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). 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].

The initial description classified them as WHO grade I lesions. Neuronal and Mixed Neuronal-Glial Tumors. Radiographics. ... CT scan and magnetic resonance imaging (MRI) revealed temporal bone tumor extending right orbital bone and diffuse leptomeningeal thickening. 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. 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. doi: 10.1016/j.crad.2012.11.009. Other differentials for an intraventricular mass including an ependymoma or intraventricular metastasis are felt less likely given the imaging appearances.
