Figures
- Fig 1.
Example of a mixed vertebral metastasis. Transverse CT scan reconstruction obtained through level of L5 before (A) and after (B) vertebroplasty shows good filling of the lytic portions.
- Fig 2.
Example of a diffuse and heterogeneous pure blastic metastasis. Transverse CT scan reconstruction obtained through level of T12 before (A) and after (B) vertebroplasty shows good filling of the vertebral body.
- Fig 3.
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.
