Effective high-frequency spinal cord stimulation for neurosarcoidosis-induced lower back and limb pain: a case report

抄録

Sarcoidosis is a multi-organ disease of unknown cause, resulting in damage to diverse organs. We report a case in which sub-perception high-frequency spinal cord stimulation (SCS) was remarkably effective in improving lumbar pain due to neurosarcoidosis lesions in the spinal cord, which had not resolved with conventional conservative treatment. A man in his 70s developed sudden left lower back and lower limb pain, muscle weakness, and spasticity. Steroid therapy was effective in temporarily relieving symptoms, but medication and nerve blocks were not effective in treating severe pain relapse. Therefore, SCS was performed as the next step in pain relief. High-frequency SCS was particularly effective in alleviating symptoms, and activities of daily living significantly improved.
