title: Traumatic pseudoaneurysm of the internal carotid artery presenting with oculosympathetic palsy.
abstract: BACKGROUND
  Blunt internal carotid artery (ICA) injury is rare but undiagnosed can have disastrous clinical consequences.
  
  
  OBJECTIVE
  To report a late presentation of blunt ICA injury in a young male following a road traffic accident.
  
  
  RESULTS
  A 16-year-old male presented 11 days following a head injury with a unilateral Horner's syndrome. Imaging confirmed a pseudoaneurysm of the ICA. The patient was treated with anticoagulant therapy.
  
  
  CONCLUSIONS
  Diagnosis of ICA injury requires a high index of suspicion and presentation with unusual neurological signs following blunt trauma to the head and neck requires prompt investigation.
