title: Unilateral right occipital condyle to C2 level spinal cord infarction associated with ipsilateral vertebral artery stenosis and contralateral vertebral artery dissection: a case report.
abstract: OBJECTIVE
  To illustrate the clinical presentation, diagnosis, management, and outcome of unilateral right occipital condyle to C2 level spinal cord infarction.
  
  
  METHODS
  A teaching hospital in Taiwan.
  
  
  RESULTS
  A 37-year-old man presented with acute-onset severe right neck pain before weakness developed in both right limbs. Early diagnosis was delayed due to mild intervertebral herniation of the C4-C5 disk. Magnetic resonance imaging revealed unilateral right occipital condyle to C2 level infarction. Angiography showed stenosis of the right vertebral artery (foraminal and intradural segments), and dissection of the left vertebral artery at the C1-C2 level. At discharge, he walked with assistance; 2 weeks later, he walked independently.
  
  
  CONCLUSIONS
  An early diagnosis is difficult but important, as it facilitates appropriate treatment for better functional and survival outcomes. Accurate early diagnosis can be made with adequate knowledge of spinal cord infarction and high index of suspicion for this condition.
