We report the safety and efficacy of combined radiofrequency ablation and cementoplasty in treating painful neoplastic bone lesions. ⋯ Combined RFA and cementoplasty appears to be safe, practical and effective in the palliative treatment of painful neoplastic lesions.

Inadvertent lumbar facet joint injection during an interlaminar epidural steroid injection (ESI) is rare when using the loss-of-resistance technique. The pattern of contrast material on the lateral view can mimic that of a successful ESI. The purpose of this study is to illustrate the imaging features of this event. ⋯ Lumbar facet joint injection has a characteristic appearance and can be distinguished from epidural injection. However, since this event can simulate the appearance of a successful ESI, it may be unrecognized during the procedure. Therefore, the true incidence is likely higher than that suggested by this study. Recognizing the imaging features of this event permits the operator to further manipulate the needle tip and increase the success rate of ESIs.
