title: Giant cell arteritis presenting with aortic aneurysm, normal erythrocyte sedimentation rate, and normal C-reactive protein.
abstract: METHODS
  We report on an extremely rare case of giant cell arteritis (GCA) presenting without elevated erythrocyte sedimentation rate or C-reactive protein level, with aortic root involvement, and in the absence of typical clinical findings.
  
  
  CONCLUSIONS
  The clinical signs and symptoms as well as the laboratory investigations involved in the diagnosis of GCA are discussed.
