Malignant primary tumors of the central nervous system (CNS) are the most common solid tumors of childhood and, after leukemias, occupy second place in frequency. The treatment of brain tumors is complex because of the histological diversity of the lesions and the tendency of most of them to spread in the neuraxis early in the course of the disease. How To Use VICE. In addition, significant sequelae secondary to therapeutic interventions may occur.Although improvements in survival rates have been obtained, they are not comparable with advances in other childhood tumors over the past three decades. This may be explained in part by the lack of knowledge about the biological behavior of these tumors, which makes them still a challenge for the treating medical team.Tumors of the posterior fossa are those primary or secondary neoplasias located in the infratentorial region, that is, under the cerebellum tent.

These tumors or neoplasms can originate in any structure of this region. The posterior fossa is small, on it is 25% of the intracranial content, but it contains vital structures like the brainstem. Thus, posterior fossa tumors are lethal by compression and secondary hypertension, obstruction of cerebrospinal fluid circulation, and destruction of the parenchyma by infiltration (Figure 1).In children, primary infratentorial tumors predominate, corresponding to 50-70% of all intracranial tumors. In adults, tumors predominate in the supratentorial compartment and in the posterior fossa, metastases are more frequent.This review will describe epidemiological, pathogenesis, clinical, molecular biology and neuroradiological aspects in general of tumors of the posterior fossa and in particular we will review the advances in molecular biology and treatment of the most frequent tumors in the area; medulloblastoma, ependymoma, low grade astrocytoma, and brain stem tumors.
