Spinal hemangioblastomas are generally intradural, most commonly occur in the cervical or thoracic regions, and occasionally may involve the entire cord. The use of molecular genetic testing for determining the genetic status of presumably at-risk relatives when a family member with a clinical diagnosis of VHL syndrome is not available for testing is not straightforward.
