What are the common brain tumors in children?

1. Ependymomas, meningiomas, schwannomas

2. Medulloblastomas, astrocytomas, ependymomas

3. Primary CNS lymphomas, glioblastomas

4. Neuroblastomas, oligodendrogliomas

The correct answer is: Medulloblastomas, astrocytomas, ependymomas

The selection of medulloblastomas, astrocytomas, and ependymomas as the common brain tumors in children is accurate due to their prevalence in pediatric neuro-oncology. Medulloblastomas are the most frequent type of malignant brain tumor found in children, typically originating in the cerebellum. They are known for their aggressive nature and are commonly seen in children aged between 3 and 8 years. This type of tumor is associated with distinct clinical presentations, including issues with balance and coordination, signs of increased intracranial pressure, and symptoms related to cerebellar dysfunction. Astrocytomas, which include a range of tumors from low-grade to high-grade, are another significant category of brain tumors in this age group. They can occur in various parts of the brain, and their prognosis varies widely depending on the grade of the tumor. Low-grade astrocytomas often have a better prognosis, while high-grade forms can be more aggressive and present more commonly in adolescence. Ependymomas, while less common than the other two types, are still prevalent among children, particularly in the posterior fossa and spinal cord. These tumors arise from ependymal cells that line the ventricles of the brain and can lead to
