Chordomas are rare malignant bone tumors that account for only 1% to 4% of all primary bone tumors. Originating from embryonic remnants of the primitive notochord, these lesions arise in the midline of the axial skeleton.1-4 Chordomas are predominantly found in the sacrococcygeal and clival (skull base) regions and typically affect adults in the fifth to seventh decade of life. Prognosis for these radioresistant lesions is highly dependent on complete resection with proven, tumor-free surgical margins.5-9 The unusual case of an L2 chordoma in a pediatric patient managed with en bloc vertebral resection and T12–L3 segmental fusion via a posterior approach is presented. A computer image guidance system was used to assist with pedicle screw placement and spinal instrumentation.10,11
