What are the signs of medulloblastoma?
The most common symptom of this tumor is frequent, severe vomiting. Less commonly seen are headache, nausea, and visual changes, such as double vision. Typically, children with medulloblastoma come to the attention of parents and teachers because of unsteady walking and clumsiness with holding things. All of these symptoms are consistent with a problem in the cerebellar region. For example, the constant vomiting results from excessive pressure in the brain due to tumor blockage of important pathways for cerebrospinal fluid flow. Please note that the symptoms mentioned here do not necessarily or automatically mean a child has a brain tumor, but further medical evaluation is required to rule out the possibility of a cerebellar tumor, such as medulloblastoma.
