title: Migration of traumatic intracranial subdural hematoma to lumbar spine causing radiculopathy.
abstract: BACKGROUND
  There have been rare reports of intracranial subdural hematoma (SDH) that migrated into the spine. All previous cases have been surgically managed and in this case report, we describe the first case of conservatively managed spinal hematoma secondary to migratory intracranial SDH.
  
  
  METHODS
  A 26-year-old male presented with a left tentorial SDH after blunt trauma. He was conservatively managed and discharged home. He presented 8 days later with worsening lower back pain that was found to be secondary to a spinal SDH.
  
  
  CONCLUSIONS
  Spinal hematomas can be a serious sequelae of migrated intracranial hematomas. Tentorial and other caudally located intracranial hematomas may be more prone to this phenomenon.
