In this report the authors discuss a case of central pain of spinal cord origin due to a spinal thoracic intramedullary cyst. Single-photon emission computerized tomography with technetium-99m hexamethylpropyleneamineoxime showed thalamic hypoperfusion contralateral to the affected leg. Surgical evacuation resulted in total relief of the pain and normalization of the thalamic alteration. The reader can infer from these findings that functional alterations in thalamic processing may be important in the genesis of central pain.
在本报告中，作者讨论了一例因胸段脊髓髓内囊肿引起的脊髓源性中枢性疼痛病例。使用锝-99m六甲基丙烯胺肟进行的单光子发射计算机断层扫描显示，患侧腿部对侧的丘脑灌注不足。手术引流使疼痛完全缓解，丘脑改变恢复正常。读者可以从这些发现中推断，丘脑处理过程中的功能改变可能在中枢性疼痛的发生中起重要作用。
