Example of a mixed vertebral metastasis presenting a posterior wall disruption associated with an epidural tumoral component; the patient didn’t present any neurologic symptom. Prevertebroplasty transverse (A) and sagittal (B) CT scan reconstruction obtained through level of L4; sagittal reconstruction after cement injection (C) shows an intracanalar leak.
