(a) Sagittal T2-weighted MRI demonstrating a heterogeneous lesion at T8 level. (b) On CT scan, the destruction of the corpus of the vertebra is seen clearly. The hyperdensity of the lesion on non-contrast sagittal CT image is remarkable. (c) Tumor is located on the mandible (black arrow). (d) The postoperative sagittal CT image showing the posterior fixation of the spine

T8 level [Figure 1a]. The lesion had a heterogeneous intensity on T2-weighted images. A computerized tomography (CT) scan [Figure 1b] showed that this expansile lytic lesion was caused by the collapse of vertebra corpus (T8) at that level. CT of the mandible revealed an expansile lytic lesion on left arm of the mandible [Figure 1c]. T5-11 stabilization was performed [Figure 1d]. The lesion was reported as "BT" [Figure 2].
