Palliation of intractable cancer pain by MRI-guided cingulotomy

Case Report: Three cases of intractable pain arising from widespread metastatic cancer with poor response to opioids were treated with MRT-guided cingulotomy. Results and Conclusions: In most cases, MRI-guided cingulotomy was associated with significant pain relief and reduced opioid use. To provide insight into the role of MRI-guided cingulotomy in oncologic pain refractory to more conservative measures, the relative risks and benefits of cingulotomy are discussed, along with the course of one patient who experienced postoperative cognitive impairment. This report also describes the relevant neurosurgical and pharmacotherapeutic issues associated with management of pain in patients with widespread metastatic disease.
