title: [Apical orbital inflammation in giant cell arteritis].
abstract: METHODS
  Our purpose is to describe a case of an acute optic neuropathy with apical muscle thickening in a patient already diagnosed with giant cell arteritis. Loss of visual acuity and perimetric concentric constriction responded rapidly to intravenous glucocorticoid therapy. There has been no relapse during continued long-term therapy with cyclophosphamide.
  
  
  CONCLUSIONS
  Giant cell arteritis is a systemic, idiopathic vasculitis; among its less frequent complications is orbital pseudotumor. Our patient required urgent treatment to avoid visual acuity loss due to compressive neuropathy and perineuritis.
