Which brain tumor is commonly seen in children?

Cerebellar medulloblastoma is a common brain tumor in children, particularly in the pediatric age group. These tumors arise from the cerebellum, which is responsible for coordination and balance. Medulloblastomas are classified as primitive neuroectodermal tumors (PNETs) and typically present in children between the ages of 4 and 8.

This tumor type is associated with symptoms such as headaches, nausea, vomiting (often due to increased intracranial pressure), and ataxia due to cerebellar dysfunction. Medulloblastomas have a characteristic histological appearance and tend to be highly aggressive, which is why early diagnosis and treatment are critical.

In contrast, the other tumors listed are less common in the pediatric population. Glioblastoma is more prevalent in adults and is a highly aggressive glioma. Meningiomas primarily affect adults and arise from the meninges, the protective coverings of the brain and spinal cord. Brainstem gliomas can occur in children but are generally less common compared to medulloblastomas. Thus, cerebellar medulloblastoma stands out as the most commonly seen brain tumor in children.
