Medulloblastoma in Adult
Initial symptoms may relate to increased intracranial pressure as a consequence of blockage of the fourth ventricle, causing morning headache, nausea / vomiting, and irritability. Later, patients can develop ataxia, frequent falls, papilledema, diplopia, nystagmus, and/or neck stiffness.
This tumor may spread through the cerebrospinal fluid (CSF) to other parts of the brain and spinal cord. It is an aggressive tumor and recurrence is common. Five-year survival rates are about 60% in all age groups. Patients with medulloblastoma are considered higher risk if they present as infants or at an older age, have metastatic disease, and if their tumors have aggressive histopathology or specific molecular markers.
