Overview First described in 1982 by Hassoun et al, central neurocytoma (CN) is a rare tumor of neuroglial origin. The role of … 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. The authors review the literature. Central neurocytoma is a hypervascular tumor but spontaneous intratumoral bleeding is very uncommon [5]. Clin Radiol. A tumor blush is frequently identified, with the mass supplied by choroidal vessels. 4th Edition Revised".

The mass is attached to the septum pellucidum but does not extend outside the ventricle. 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). Central neurocytomas demonstrate neuronal differentiation and histologically appear similar to oligodendrogliomas which, historically, resulted in many tumors erroneously categorized.

Emphasis is placed on radiological and pathological features not previously described. Diagnosis. The first report resulted in increased recognition of the tumor, and a number of reports have since been published in the literature. Clusters of cysts gave the tumours a "swiss cheese/soap bubble" inhomogeneous hyperintense appearance on T2WI and FLAIR images. Neuronal and Mixed Neuronal-Glial Tumors. Contrast enhancement is usually mild to moderate. We, therefore, investigated the similarities and differences between these types of tumors to get a better understanding of how they … link. On MRI, the solid parts of the tumours were mainly hypo- to isointense on all T1WI and isointense to grey matter on T2WI. Most of them occur as an exophytic, well circumscribed, globular mass that protrudes into the ventricles.
