title: Recurrent subdural hematoma secondary to headbanging: A case report.
abstract: BACKGROUND
  "Headbanging" is the slang term used to denote violent shaking of one's head in time with the music. This abrupt flexion-extension movement of the head to rock music extremely rarely causes a subdural hematoma.
  
  
  METHODS
  A 24-year-old female was admitted to our department because of right sided partial seizure and acute or subacute subdural hematoma over the left cerebral convexity. She had no history of recent head trauma but performed headbanging at a punk rock concert at 3 days before admission. Since, she had a previous acute subdural hematoma on the same side after an accidental fall from a baby buggy when she was 11 months old, the present was recurrent subdural hematoma probably due to headbanging.
  
  
  CONCLUSIONS
  Headbanging has the hazardous potential to cause a subdural hematoma.
