Two patients underwent percutaneous image-guided electrochemotherapy on blastic spine metastases involving posterior walls of the lumbar vertebral bodies with epidural extension. These treatments were performed safely under cone beam computed tomography. Local tumor control was obtained on the subsequent follow-up as well as pain relief and disability improvement. Electrochemotherapy might be considered for patients with thus far no other alternative in order to obtain tumor control and improvement in patients' quality of life.
