Overall, intraventricular supratentorial tumors are rare in childhood. Classification can be based on the separation of lesions originating in intraventricular structures, such as choroid plexuses, from glial neoplasms of the ventricular wall which tend to infiltrate the ventricular cavities. Aim of the present study is to review the most common neoplasms of this region in childhood. Choroid plexus tumors (papillomas and carcinomas) and subependymal giant cell astrocytomas are dealt with, while for the other neoplasms which are rarer or more typic of other age ranges, specific reports should be consulted. Choroid plexus papillomas affect infants and are the most frequent oncological type among congenital tumors. The malignant variant (grade III-IV) is represented by the less frequent the neoplasms. The malignant variant (grade III-IV) is represented by the less frequent choroid plexus carcinoma which is markedly invasive with respect to adjacent nervous structures and has a high tendency to form metastases even at onset. Anaplastic papillomas are intermediate forms whose correct histopathology is still debated. Most frequent glial tumors are subependymal giant-cell astrocytomas. They are benign tumors (grade I) typically albeit not constantly associated to tuberous sclerosis. In this case the differentiation from subependymal nodules plays a major role. Contrast enhanced CT is fundamental in this assessment. Anaplastic variants, though rare, are well-known.
