Desmoplastic infantile ganglioglioma, or DIG, is a rare type of brain tumor that usually occurs during early childhood. It is most commonly found in children younger than 18 months. Many times, DIG may have started very early in childhood or even before a child was born. A tumor begins when healthy cells change and grow out of control, forming a mass. DIG is a glioma, which is a type of tumor that starts in the glial cells. Glial cells are the supportive cells in the brain. DIG usually occurs on 1 side of the brain and can sometimes be very large.

DIGs are generally classified as low-grade, slow-growing tumors. Generally speaking, DIGs are benign, which means they are not cancerous or malignant. However, because they are located in the brain and require surgery, DIGs are potentially life-threatening.

This section covers DIG diagnosed in children. Learn more about brain tumors in adults.
