title: Bilateral Atherosclerotic Internal Carotid Artery Occlusion with Intact Cerebral Glucose Metabolism: A Case Report.
abstract: BACKGROUND
  Mild neurologic deficits concomitant with bilateral internal carotid artery occlusion (BICAO) is very rare and its treatment is still unclear.
  
  
  METHODS
  Herein, we report a case of a 67-year-old man with BICAO. The collateral circulation was rich, the symptoms were mild, and only standard pharmacotherapy was prescribed. Follow-up Mini-Mental State Examination, fluorine-18-fluorodeoxyglucose positron emission tomography, and magnetic resonance perfusion-weighted imaging were performed for 6 months.
  
  
  RESULTS
  The results showed uniform reduction in perfusion throughout the brain, normal glucose uptake by the brain, and no ischemic events and cognitive impairment during the follow-up period.
  
  
  CONCLUSIONS
  For BICAO patients who are with mild neurologic deficits and good cerebral collateral and metabolism, the timely administration of pharmacotherapy might be safe and effective. Thus, in our patient, a favorable prognosis was achieved, but further follow-up is still required.
