Abstract
BACKGROUND: Computed tomography (CT)-guided cordotomy has been shown to be a safe and effective method for treating cancer pain in adults in a palliative care setting. Its effectiveness has been rarely reported in children. During cordotomy, patient feedback is considered essential. Unfortunately, in this report, the featured patient's age and demeanor precluded an awake cordotomy. The authors report the first case, to their knowledge, of percutaneous cordotomy with the patient under general anesthesia. OBSERVATIONS: An 11-year-old boy with osteosarcoma of the right pelvis presented with medically refractory unilateral nociceptive pain. The pain prevented ambulation, interfered with sleep, was the focus of his concern, and could not be relieved without sedation. A left percutaneous CT-guided cervical cordotomy while he was under general anesthesia was performed without complication and provided sufficient pain relief to allow ambulation and restorative sleep. Pain was no longer an issue for the patient and his family. LESSONS: CT-guided percutaneous cervical cordotomy can be accomplished in a pediatric patient under general anesthesia. The risks of cordotomy under general anesthesia without patient feedback must be weighed against the opportunity to improve palliative care. https://thejns.org/doi/abs/10.3171/CASE2427.
