Computed tomography (CT) of the thoracic spine. Sagittal (a) and coronary (b) CT scans revealing multiple osteolytic lesions. c. Axial CT image of T10 depicting destruction of the rear edge without spinal obstruction. d. Axial image of the CT scan of T12 showing osteolytic lesions centrally and in proximity of the left pedicle.

123Metaiodobenzylguanidine scan, magnetic resonance imaging (MRI), and computed tomography (CT) scans (Figure 1) revealed multiple osteolytic lesions of the entire spine, especially prominent in T1, T5, T10, and T12. In the case of T10, CT and MRI scans showed an instable fracture of the vertebral body with entire destruction of the rear edge without spinal obstruction and a pathologic fracture of the left pedicle (Figure 1a, c). T12, the CT scan revealed osteolytic lesions in the center of the vertebral body and another metastasis in proximity of the left pedicle (Figure 1d).

Postoperative computed tomography (CT) of the thoracic spine. Sagittal (a) and coronary (b) CT scans after cement-augmented dorsal instrumentation of T8-T12. (c) The postoperative axial imaging (CT) of T10 reveals identical results with respect to obstruction of the spinal canal, as compared to the preoperative state. (d) Axial CT scan of T12 showing cement augmentation prior to pedicle screw placement.

A CT scan after mobilization of the patient confirmed the correct position of the implants and showed unaltered results for T10 with respect to vertebral body height and spinal obstruction, and no signs of cement extrusion at the segment of T12 (Figure 2).
