A Case Report of Paraplegia Caused by Spinal Cord Infarction.

Spinal crod infarction is rare in comparison with cerebral infarction. The onset is rapid and it is difficult to diagnose decisively. We report on the clinical course of a patient with spinal cord infarction and detail the and serial MR imaging from acute to chronic phase. The patient, a 47-year-old female, had suddenly developed paraplegia. She remained alert but had flaccid palsy of the lower limb, hypaesthesia, and numb sensation of the lower limb. We could not find any abnormal finding on myelography. MR impaging showed a high intensity signal in the anterior area of her spinal cord from 7th to 12th thoracic spinal cord on T2W-Imaging at 56 hours after the onset. There was a clear high intensity area in the anterior area of spinal cord from 7th to 12th thoracic segments on T2W-Imaging after 23days. According to the acute onset and the high intensity area seen in anterior area of the spinal cord on T2 W-Imaging, we diagnosed anterior spinal artery infarction.
