What is chordoma?
Chordoma is a slow growing cancer of tissue found inside the spine. Chordoma can happen anywhere along the spine. It is most often found near the tailbone (called a sacral tumor) or where the spine meets the skull (called a clival tumor).
What is the difference between chordoma and schwannoma?
Schwannoma – These tumors damage the bone differently than chordomas do, look different on imaging tests, and do not spread to nearby muscles or joints. Other tumors of the spine and skull base – These include other bone cancers such as Ewing sarcoma and osteosarcoma, as well as a type of nervous system tumor called a myxopapillary ependymoma.
What is the difference between chordoma and giant cell tumor?
Giant cell tumor of the bone – These tumors look somewhat different on imaging tests than chordoma, and tend to be located in the upper part of the sacrum. Schwannoma – These tumors damage the bone differently than chordomas do, look different on imaging tests, and do not spread to nearby muscles or joints.
How common is a chordoma tumor?
These tumors affect about 1 person in 1 million people per year. One to four percent of all primary bone tumors are chordomas. Chordomas typically grow slowly. They are often found in the front (anterior) part of the spine or base of the skull. They can occur at any point along the spine.
Can a notochordal cell tumor look like a chordoma?
Benign notochordal cell tumors – These benign spine tumors can be seen on an MRI or CT scan and can sometimes look like chordoma. However, benign notochordal cell tumors stay confined within the bone and do not spread into other tissues like chordomas can.
What is the rate of incidence for chordoma?
Worldwide, one in one million people are diagnosed with chordoma per year. How is chordoma diagnosed? Symptoms of chordoma can be very different depending on where in your spine the chordoma starts. When chordoma starts at the base of the skull you may have headaches or double vision.
