Astrocytoma is a brain tumor which comes from cells located in the supporting tissue of neurons. In adults, the tumor is located exclusively in the cerebral hemispheres, whereas in children, it can also reach the cerebellum. It can be the cause of seizures, headaches, or motor neurological signs. By virtue of its progression, it generates a compression of the other components of the brain, leading to intracranial hypertension. An imaging scan or MRI can detect this benign tumor. Depending on its clinical impact and location, the choice of surgical removal or simple monitoring can be made.
