title: Delayed myelopathy after trivial neck injury in a patient with a cervical neurenteric cyst.
abstract: BACKGROUND
  Neurenteric cysts are rare spinal lesions of congenital origin. They usually present insidiously with a long history of local spinal pain, radiculopathy and myelopathy. We report a 14-year-old male with a high cervical neurenteric cyst who developed a progressive myelopathy after minor neck trauma. Full recovery followed a partial cyst excision and decompressive procedure.
  
  
  CONCLUSIONS
  The possible pathogenic mechanisms for this unusual presentation include hemorrhage into the cyst, sudden mechanical compression from abnormal spinal movement of a chronically distorted and compressed spinal cord, or an increase in the size of the cyst secondary to accumulation of cyst fluid. In this case a small increase in the cyst size may have resulted in increased mechanical distortion and spinal cord dysfunction on a compressive and ischemic basis.
