Impar ganglion is a solitary ganglion located retroperitoneally at the end of paravertebral sympathetic chain and usually in front of sacrococcygeal joint. Solitary or metastatic tumour in the surrounding tissues causes poorly localized pain. This case report presents a 75-year old male patient with colon cancer, whose severe pain during defecation could not be controlled with conventional high-dose opioid application but with transcoccygeal radiofrequency thermocoagulation. Radiofrequency thermocoagulation is promising not only for chronic pelvic pain control but also in pelvic pain secondary to malignancy particularly when the ganglion is localized by radiologic imaging techniques.
奇神经节是一个孤立的神经节，位于腹膜后椎旁交感神经链末端，通常在骶尾关节前方。周围组织中的孤立性或转移性肿瘤会导致定位不明确的疼痛。本病例报告介绍了一名75岁的男性结肠癌患者，其排便时的剧痛无法通过常规高剂量阿片类药物控制，但通过经尾骨射频热凝术得以缓解。射频热凝术不仅有望用于控制慢性盆腔疼痛，而且对于恶性肿瘤继发的盆腔疼痛也有效果，特别是当通过放射影像学技术定位神经节时。
