title: Calcification of thoracic aorta - solar eclipse sign.
abstract: BACKGROUND
  Calcification of thoracic aorta is very common in old people, especially ones with hypertension. This can sometime be visible on plain chest radiograph.
  
  
  METHODS
  We present a case of a male patient who had extensive deposition of calcium in the thoracic aorta.
  
  
  CONCLUSIONS
  The relationship between aortic calcification and coronary atherosclerosis remains contentious. Computed tomography of the thorax can display this calcification which appears like 'solar eclipse'.
