This MRI scan shows a tumor (teratoma) at the base of the spine (seen on the left lower edge of the screen), located in the sacrum and coccyx (sacrococcygeal) area. Teratomas are present at birth and may contain hair, teeth, and other tissues.

Malignant teratoma

A malignant teratoma is a type of cancer consisting of cysts that contain one or more of the three primary embryonic germ layers: ectoderm, mesoderm, and endoderm. Because malignant teratomas have usually spread by the time of diagnosis, systemic chemotherapy is needed. The prognosis for people with malignant teratomas is based on the size of the tumor, its location and the age of the patient.
