A chondrosarcoma is a malignant tumor found at the petro-occipital synchondrosis, the joint between the clivus and the petrous bone of the skull.

Treatment for Chondrosarcoma

The treatment is tailored to the size and extent of disease with consideration given to the health of the patient. Some patients are not able to undergo surgery. Treatment usually involves a combination of surgery and radiation treatment. These patients require serial MRI scans for their entire life.
