Sagittal CT reformation (a) shows multiple lytic and blastic metastatic breast cancer lesions in the thoracic spine with a compression fracture in the upper thoracic spine (yellow arrow). Sagittal T1-weighted image (b) shows multiple hypointense lesions, many of which enhance on the postcontrast T1-weighted MR (c). The STIR image (d) depicts both hyperintense (lytic) and hypointense (blastic) lesions. A mildly enhancing epidural component compresses the thecal sac (red arrows).
