Spine tumors are either primary tumors which originate from the spine itself and its adjacent structures or secondary (metastatic) tumors of distant organs which spread hematogenously and lymphatically and are located in the spine and its surrounding tissues. As the spine is well vascularized and has close relationship with regional lymphatic and venous drainage systems (especially Batson’s venous plexus), it is generally susceptible to metastasis. Metastatic tumors are most common (97%) tumors of the spine
