Pineal gland tumours
Only 1 in every 100 brain tumours (1%) are pineal tumours.
The pineal gland is found at the back of the third ventricle of the brain. Ventricles are fluid-filled spaces within the brain.
Pineal-region tumours can be made up of different types of cells. The most common type of tumour in the pineal region is known as a germinoma or germ cell tumour. Germinomas develop from germ cells (cells in a very early stage of development). They are fast-growing and may often spread to other parts of the brain.
Other types of pineal tumour include: astrocytomas, teratomas, meningiomas, pineocytomas and pineoblastomas.
Although this type of tumour is more common in adults, it can occur in children. For unknown reasons, it is more common in men than in women.
