Abstract

Central pain can occur in any lesions along the central nervous system affecting the spinothalamocortical pathway. Although diverse etiologies have been reported to cause central pain, there are few reports on the occurrence and surgical treatment of central pain following a traumatic brain injury (TBI). This paper describes the occurrence of central pain following a severe TBI, in which the diagnosis of central pain was typically delayed due to the patient's decreased ability to express his pain for severe aphasia as a neurological sequela. The severe burning pain, deep pressure-like pain, and deep mechanical allodynia, which presented over the contralateral side to the TBI, were successfully relieved with motor cortex stimulation (MCS). The analgesic effect of stimulation was found to be long lasting and was still present at the 12-month follow up. As shown in this patient, the occurrence of central pain syndrome should be considered by physicians caring for TBI patients, and a comprehensive, systematic study will be needed to determine the prevalence of central pain after a TBI.
