The authors present the patient with an incomplete spinal cord injury (Brown Sequard syndrome) after a stab injury. A 42-year-old man had been stabbed with a knife during a fight. On physical examination, we found a 4cm laceration in the back of the upper neck. The neurological examination revealed that the motor strength of the left upper and lower extremities was a grade two. On the contralateral side, decreased pain and temperature sensations were observed below the C3 dermatome level. Magnetic resonance imaging of the cervical spine showed a hemi-transection of the spinal cord at the C1-C2 level. The patient was treated with steroids, antibiotics, and rehabilitation programs. The patient made a good recovery.
