Posterior fossa tumors are predominantly seen in children with a peak incidence in the first decade. The most common presenting symptoms are raised intracranial pressure with headache and vomiting. Majority of the tumors are medulloblastomas, ependymomas, and cerebellar astrocytomas
Dear Shaghayegh!
I also deal with brain tumors in children.
I believe that the main reason for the formation of tumors (medulloblastomas, neuroblastomas, ependymomas), especially in young children, are genetic mutations that occurred at the stage of the embryo (fetus). Already at birth, these babies may have tumor cells in the brain that proliferate until a tumor forms that manifests itself clinically with the symptoms you specify.
Shaghayegh Rastgoo Agreed!! Genetic mutation, such as dysfunction of tumor suppressor gene (p53 gene) or activation of oncogene, is the cause of posterior fossa tumors in children. Although no specific cause has been identified.
