A 77-year-old female patient with multiple vertebral metastases from a renal cell carcinoma, which had been stabilized with several spinal fusion operations, presented herself to the emergency room complaining of weakness in her left leg. A CT examination was performed to assess the degree of osteolytic destruction, the integrity and position of the osteosynthetic material and to rule out an infiltration or compression of the spinal canal and the neuroforamina by metastases or hematoma.
