General Discussion

Medulloblastoma is the most common malignant brain tumor in children. Medulloblastomas by definition occur in the cerebellum, which is the part of brain located at the base of the skull, just above the brainstem. The cerebellum is involved in many functions including coordination of voluntary movements (e.g., walking, fine motor skills) and regulating balance and posture. Medulloblastomas arise from primitive, undeveloped cells in the brain. Most medulloblastomas occur in infants and children. Less commonly, these tumors can develop in adults as well. Symptoms associated with a medulloblastoma include headaches in the morning that improve as the day goes on, recurrent vomiting and difficulty walking and with balance. Medulloblastomas can spread to other areas of the central nervous system. The exact cause of a medulloblastoma is unknown.
