Chordoma is a rare type of tumor that occurs in the bones of the skull base and spine. These tumors arise from the remnants of the notochord, a flexible, rod-like structure that provides support to the developing embryo. Chordomas are complex tumors to treat due to the involvement of critical structures such as the brainstem, spinal cord, and important nerves and arteries. About 30 percent of all chordomas are form within the center of the head in an area called the skull base – usually in a bone called the clivus. Skull base chordomas are sometimes considered brain tumors because they can grow toward the brain.
