title: [Orbital sarcoidosis--a case with an unusual course].
abstract: BACKGROUND
  Most cases of orbital sarcoidosis are associated with a systemic sarcoidosis.
  
  
  METHODS
  A 67-year-old woman suffered from an orbital mass on the right side, which led to disturbance of the ocular motility. Slight improvement was achieved by the administration of systemic steroids.
  
  
  RESULTS
  Histologically a chronic granulomatous inflammation was revealed in the biopsy of the orbital mass. The suspected diagnosis was sarcoidosis, but three conventional chest X-rays within 10 months and the serum angiotensin-converting-enzyme were normal. Suprisingly a computertomography of the chest showed mediastinal lymphomas.
  
  
  CONCLUSIONS
  Granulomatous orbital inflammation without any local cause or other systemic granulomatous disease strongly suggests a systemic sarcoidosis. In case of missing lymph node enlargement in conventional chest X-ray computertomography should be performed.
