(a) Forty-two-year-old female presents with worsening back pain and thoracic discomfort for the past 3 months. Preoperative anterior-posterior (AP) radiograph demonstrating thoracic deformity secondary to giant cell tumor with complete osteolysis of the pedicle. (b) Preoperative lateral radiograph demonstrating kyphosis secondary to vertebral body destruction secondary to the giant cell tumor. (c) Preoperative sagittal computed tomography (CT) scan demonstrating T12 vertebral body osteolysis secondary to giant cell tumor infiltration. (d) Preoperative coronal CT scan demonstrating thoracic spinal deformity secondary to pathologic burst fracture of the T12 vertebral body. (e) Preoperative axial CT scan demonstrating burst fracture of T12 vertebral body secondary to giant cell tumor infiltration with extension into the spinal canal.

(a) Postoperative anterior-posterior (AP) radiograph demonstrating placement of the expandable titanium cage and instrumentation. (b) Postoperative lateral radiograph demonstrating placement of the expandable titanium cage and instrumentation and restoration of normal thoracic kyphosis. (c) Two-year postoperative sagittal computed tomography (CT) scan demonstrating arthrodesis and resolution of deformity without cage migration. (d) Two-year postoperative coronal CT scan demonstrating proper placement of expandable titanium cage with arthrodesis across the graft. (e) Two-year postoperative axial CT scan demonstrating expandable titanium cage with instrumentation and no recurrence of the giant cell tumor. (f) Two-year postoperative sagittal magnetic resonance imaging (MRI) demonstrating placement of expandable titanium cage and decompression of spinal cord without recurrence of the giant cell tumor. (g) Two-year postoperative axial MRI demonstrating placement of expandable titanium cage without recurrence of the giant cell tumor.
