30 years old male, who had felt nuchal pain for 10 days as prodrome, had sudden onset of weakness and numbness on the right upper and both lower limbs within 30 minutes.
Neurological examination revealed right hemiparesis and hypesthesia (pain and temperature) on the right upper and the left lower extremities. Reflexes of four limbs were all hyperactive. X-ray film of the cervical spine, C. S. F. and C. B. C, were all negative. The symptoms gradually progressed in right hemiparesis, sensory disocciation and recto-vesical disfunction in 5 days, and then followed by rapid recovery.
Five months after the onset of the symptoms, patient returned to normal life. Mild degree of presthesia remained on the left thigh.
This case was considered to be caused by localized occulusion of the anterior spinal artery in right side of the upper thoracic level of the spinal cord.
