As a consequence, its frequency varies greatly in the different series, ranging from 1.3% [627] to 9.6% [3803] of all intracranial tumors and from 5% [2901] to 18% [3803] of all gliomas. In the

It derives from the epithelium of the choroid plexus, which in turn represents the differentiation of primitive neuroepithelial elements which come into contact with

The frequency of neural tumor cells is very variable, ranging from tumors in which neural cells clearly prevail (gangliocytomas), to those in which they are very rare when compared with the predominant glial elements. One of the fundamental problems, especially in the latter case, is

However, despite its close relationship with the ependymal covering, this tumor may grow deeply into the white matter.
