Posteria fossa syndrome
Your child's neurosurgeon will explain the risks associated with surgery on their medulloblastoma, including a condition known as posteria fossa syndrome.
Posteria fossa syndrome develops in around 25% of children with medulloblastoma, with symptoms generally appearing one to three days after surgery. Symptoms can continue for months to years and can vary from child to child. The following symptoms are only a guide, but may include:
- weakness in one side of the body
- loss of speech
- difficulty swallowing (dysphagia)
- facial paralysis on one side
- poor balance (ataxia)
