Neonatal segmental myoclonus associated with hyperglycorrhachia.

Segmental or spinal myoclonus is an uncommon involuntary movement in infancy which has been attributed to sepsis, degenerative and developmental diseases of the spinal cord, birth trauma, and sclerosing panencephalitis. A premature infant presenting with segmental myoclonus associated with extreme hyperglycorrhachia secondary to the administration of parenteral nutrition through a femoral percutaneous indwelling central catheter that had inadvertently migrated into a paravertebral vein is reported. We recommend a lateral abdominal radiograph in addition to the usual anteroposterior view to confirm the correct placement of femoral catheters.
