Aim: To evaluate the clinical, pathological and neuroradiological features of intraventricular central neurocytoma in six patients. Eight lesions were unilateral ventricle (44%) and ten were located in both lateral ventricles. 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. On CT, diffuse and diverse calcifications were observed in nine cases and cysts varying in sizes were revealed in all. 2015 Jan;26(1):11-9. doi: 10.1016/j.nec.2014.09.012. It is discovered due to symptoms of raised intracranial pressure. 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. ...

The mass is attached to the septum pellucidum but does not extend outside the ventricle. 2018 Oct;28(10):4306-4313. doi: 10.1007/s00330-018-5442-y. 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: To evaluate clinical findings and radiological characteristics of central neurocytoma (CN) in 18 patients and magnetic resonance spectroscopy (MRS) features in one additional case. Radiographics.  |  2. MRS was also obtained for one additional case. Central neurocytoma (CN) is a benign intraventricular neuronal tumor with a favorable prognosis. Objectives: [1] who studied two patients with intraven - tricular tumors using electron microscopy. Imaging of central neurocytoma is usually characteristic. Central neurocytomas are typically seen in young patients (70% diagnosed between 20 and 40 years of age) and account for less than 1% (0.25-0.5%) of intracranial tumors 10,11.

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. 9. Studies comparing intraventricular oligodendroglioma (IVO) and central neurocytoma (CN) in terms of their clinical, radiological and pathological features are scarce. 1. (2009) ISBN:364202873X.

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.
