The common feature of chordoma imaging is extensive bone destruction, and calcified shadows can also be seen within the tumor. Calcified shadows are not just calcium deposits, but are now mostly considered to be dead bone after destruction of bone tissue and do not represent degenerative calcification of the tumor itself. In addition, some patients may have metastases to the chest and bone locations. Once diagnosed, chordoma requires early surgical treatment combined with radiation therapy. Because the average survival period of chordoma is about 6.3 years, only early medical intervention can improve the survival rate. Moreover, chordoma is prone to recurrence, which usually starts 2-3 years after surgery, and the recurrence is an important cause of aggravation of the patient’s condition and death, therefore, patients with chordoma must be treated actively, and emphasize on the regular follow-up.
