Desmoplastic infantile ganglioglioma (DIG) is a rare type of brain tumor that can occur during childhood. A tumor begins when normal cells change and grow uncontrollably, forming a mass. A tumor can be benign (noncancerous) or malignant (cancerous, meaning it can spread to other parts of the body). DIG is a type of glioma, a tumor that starts in the glial cells, which are supportive cells in the brain. It usually occurs on one side of the brain, can be very large, and is more common for children younger than one year old. DIG is made up of more than one type of cell and also contains cysts. It is thought that DIG begins even before a baby is born.
DIG was originally classified as a low-grade, slow-growing tumor that is usually noncancerous. However, in some instances, the tumor grows more rapidly and is more aggressive in spreading to other parts of the brain or body; this is called a high-grade tumor (see Staging/Grading).
