RESUMO
BACKGROUND: Cancer pain management in children is challenging owing to their unique patient characteristics. We present the case of a 10-year-old girl whose cancer pain was successfully managed using an intrathecal neurolytic block. CASE PRESENTATION: The patient experienced severe cancer pain due to recurrent right ilium osteosarcoma. The tumor progressed rapidly despite chemoradiotherapy and gradually invaded the right lumbar plexus, which resulted in severe neuropathic pain in the right lower extremity. Systemic analgesics failed to attenuate the pain. We performed an intrathecal neurolytic block using 10% phenol-glycerol. The neurolytic block completely relieved her right lower extremity pain. After the block, the patient's quality of life improved, and she spent her time with family. CONCLUSIONS: The intrathecal neurolytic block successfully relieved the patient's cancer pain. Successful intrathecal neurolytic blocks require meticulous pain assessment of individual patients, to avoid possible serious complications such as paresis/paralysis and bladder/bowel dysfunction.
