Abstract
OBJECTIVES: This study reports on a patient who developed degeneration of an injured spinothalamic tract (STT) detected on diffusion tensor tractography (DTT) following mild traumatic brain injury (TBI). CASE DESCRIPTION: A 56-year-old female had suffered from head trauma resulting from a pedestrian car accident. The patient did not experience loss of consciousness or post-traumatic amnesia and the patient's Glasgow Coma Scale score was 15. She had begun to feel pain in her left hand and foot at ~ 7 days after onset. The characteristics and severity of pain were as follows: constant tingling and pricking sensation without allodynia or hyperalgesia (Visual Analogue Scale score: 3~4). No specific focal lesion was observed on brain and spine MRI and an electromyography study showed no evidence of peripheral nerve injury or radiculopathy. At 6 months after onset, the central pain in the left hand and foot became aggravated, with a Visual Analogue Scale score of 6. RESULTS: On 1-month DTT, partial tearing was observed in both STTs. In contrast, both partially torn STTs had become atrophy on 9-month DTT. CONCLUSIONS: This study recommends further studies conducted on the prognosis (regeneration or degeneration) of injured STTs and on the effect of change of an injured STT on central pain.
