The final diagnosis of spinal tumors is based not only on patient age, histologic features, and topographic features of the tumor (Figure 1 ), but also on analysis of the pattern on imaging. Benign bone tumors that are more aggressive, such as giant cell tumor or chondromyxoid fibromas, usually require surgery. In these cases, techniques such as synthetic bone graft substitutes are used to rebuild rather than remove bone. Drugs such as denosumab or doxycycline are also used to treat specific tumors.
