Germ cell brain tumors usually grow in the middle of the brain, in an area called suprasellar region, or in the pineal region which is nearby. They are often malignant tumors, but there are many subtypes, such as the teratoma, germinoma, the embryonal carcinoma and the choriocarcinoma, which are more aggressive. They arise from germ cells in the brain, and there are mixed germ cell tumors as well.

They usually spread through the cerebrospinal fluid to other areas in the brain and the central nervous system, and usually start with headaches and vision problems, and hormonal issues if the tumor is located in the suprasellar region. They are not quite common, but they mainly appear in young people under 30 years old.
