Which childhood brain tumor accounts for 15-25% of cases?

• A. Medulloblastoma
• B. Cerebellar Astrocytoma
• C. Acute Lymphoblastic Leukemia (ALL)
• D. Retinoblastoma

Answer: (A)

Medulloblastoma is the most common malignant brain tumor in children, accounting for approximately 15-25% of all pediatric brain tumors. It typically arises in the cerebellum and can present with symptoms such as headache, vomiting, and balance issues due to its location. Medulloblastomas are classified as primitive neuroectodermal tumors and are characterized by their tendency to spread to other parts of the brain and spinal cord, making early detection and treatment critical for patient outcomes. The classification and prevalence of brain tumors in children are well-established, with Medulloblastoma being a significant focus due to its prevalence and treatment challenges. The other conditions listed are either not classified as brain tumors or do not account for this percentage of cases. For example, cerebellar astrocytoma is a less common type of brain tumor, and acute lymphoblastic leukemia (ALL) is a type of blood cancer, while retinoblastoma is primarily a cancer of the retina, not the brain.
