    Abstract:
    Giant cell tumor (GCT) is an intermediate malignant bone tumor which mostly involves long extremity bones, less commonly involving the spine with sacral predominance. Cervical spine involvement is rare. According to literature, the selective approach for the treatment of GCT is en bloc resection with spinal reconstruction. For unusual sites, such as cervical region, which is a mobile spinal segment and critically proximate to the cervical spinal cord, great vessels, and vital organs, it is almost impossible to perform the selective approach for treatment. Alternative approaches in such situations are under investigations. We present a case of C2 vertebral body GCT, who was treated with polymethylmethacrylate intravertebral injection and was followed by adjuvant therapy with denosumab. A 16-year-old boy without any past medical history presented with progressive suboccipital and axial neck pain since 3 months earlier, which had not responded to conservative treatments. There was no neurologic deficit, and pain was significantly controlled. In the 1-year follow-up, no complication and tumor recurrence was seen. Vertebroplasty with bone cement for lytic spinal GCT lesions, followed by adjuvant therapy with denosumab, not only is a less invasive treatment but also has good results in spinal stability, patient recovery, and 12-month recurrence.
