Crossed-Probes Cryoablation for the Treatment of a Sclerotic Vertebral Metastasis Abutting the Spinal Canal

A 44-year-old woman presented with lumbar pain (visual analog scale [VAS]  = 9) secondary to adrenocortical carcinoma sclerotic L4-vertebral metastasis. The positron emission tomography-computed tomography hypermetabolic lesion (Fig 1a,d) was unresponsive to radiotherapy or chemotherapy. She refused surgery. Following general anesthesia and aseptic preparation, 2 power d rill-mounted (Aesculap, Center Valley, Pennsylvania) k-wires were inserted in each vertebral pedicle with lateromedial opposite directions, resulting in crossed wires.
