Up to 8% of childhood brain tumors are located in the pineal gland, a structure located in the center of the brain that releases a series of hormones to the bloodstream. There are many types of pineal tumors, but true pineal cell tumors are those that develop from the pineal gland itself. The most aggressive is called pineoblastoma, and it usually causes a blockade in the normal circulation of cerebrospinal fluid, and several symptoms such as headaches, visual problems, nausea, and vomiting.
