Definition: A central neurocytoma is a rare, low-grade tumor. The World Health Organization classifies this tumor as a grade II. Central neurocytomas grow into the ventricles, spaces in the brain where cerebrospinal fluid is secreted and flows. The tumor often blocks the flow of cerebrospinal fluid, causing hydrocephalus, a build-up of fluid in the brain.
Symptoms: The most common symptoms of a central neurocytoma are due to increased intracranial pressure from hydrocephalus. Symptoms of increased intracranial pressure are headaches, nausea, vomiting, visual changes, and changes in behavior.
Evaluation: Central neurocytomas are evaluated with MRI and CT scans.
Follow-up: Long-term follow-up with regular brain scans is recommended to watch for tumor recurrence.
