Gangliocytoma
Gangliocytoma “is a rare type of central nervous system (CNS) tumor made up of mature neurons,” according to the NIH. Though this condition can occur at any age, it is most often seen in those between the ages of 10 and 30.
Gangliocytomas occur most often in the temporal lobe of the brain. But the NIH says they can arise anywhere in the central nervous system. Other sites where gangliocytomas can occur include the cerebellum, brainstem, floor of the third ventricle and spinal cord.
Though exact symptoms related to gangliocytomas depend on the tumor's location, there are signs to look for. The most common of these is seizures. However, those affected can also experience increased brain pressure, endocrine disorders and focal symptoms.
The good news is that gangliocytomas are not usually malignant and grow slowly. Once a gangliocytoma is discovered, it is usually surgically removed.
