Abstract
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.
