An 84-year-old woman with prior history of L4-L5 laminectomy and L4 spinous process resection 25 years ago, presented for an acute exacerbation of her chronic right sciatica not responsive to analgesics and non-steroidal anti-inflammatory drugs. There was no motor deficit. After imaging workup (Figs. 1, 2 and 3), she underwent right L3-L4, L4-L5 and L5-S1 facet medial branch block without significant improvement.
