title: Spinal cord tethering by aberrant nerve root in myelomeningocele: case report.
abstract: BACKGROUND
  A 2,796-gram male baby was born at 40 weeks gestation by vaginal delivery. Soon after, he was admitted at our department for treatment of a dorsal appendage.
  
  
  CONCLUSIONS
  Magnetic resonance (MR) imaging showed a low-position spinal cord, skin-covered myelomeningocele, syringomyelia, and a tethered cord. Resection of the caudal appendage and tethering tissue was performed 22 days after birth under electrophysiological monitoring. Histopathological examination of the caudal appendage that was covered with skin revealed the presence of spinal cord tissue and peripheral nerve tissue. The string-like tethering tissue that extended from the spinal cord to the caudalis was a nerve root, and there was fiberization of the caudalis. The syringomyelia was improved at postoperative MR imaging. To our knowledge, there is no report of a similar case in the literature. We report rare combination of myelomeningocele and spinal cord tethering by aberrant nerve root with thoracic syringomyelia.
