High voltage electrical injury leading to a delayed onset tetraplegia, with recovery

High voltage electrical injury can cause considerable damage to the central nervous system. Delayed spinal cord injury is uncommon, usually incomplete, and comprises predominantly motor fallout. The injury can be progressive, with only a few patients showing partial improvement. We present a case report of a 20-year-old male who had a delayed onset spinal cord injury after a high voltage electrical injury. The symptoms started several days postburn with an ascending paralysis, leading to tetraplegia. Gradual recovery became evident at 3 months after the accident, starting with his arms and later showing partial recovery of his lower limbs. The mechanisms of injury and pathophysiology to the spinal cord are poorly understood. Possible explanations for the delayed onset of neurologic complications are given. The exact reasons for the delayed, ascending paralysis and the mechanism of recovery still need further investigation.
