Lumbosacral plexus avulsion injury: clinical, myelographic and computerized tomographic features.

A rare case of lumbosacral plexus avulsion studied with computerized tomography (CT) in a 5-year old Saudi involved in a vehicular accident with resultant left lower limb monoparesis is presented. Myelography and CT were superior to electromyographic findings in this case. Such cases should be closely followed and surgical exploration and decompression offered if any evidence of cauda equina compression develops.
