title: Asymptomatic fibrous dysplasia of the temporal bone.
abstract: BACKGROUND
  Fibrous dysplasia is a bone disorder of unknown origin in which normal bone is replaced with fibrotic tissue and disorganised bone trabeculae. The temporal bone is rarely affected. Because of the slowly progressive course of the disease, many mild cases may never be recognised and are found incidentally. We present a patient with fibrous dysplasia of the right temporal bone, who had few complaints.
  
  
  OBJECTIVE
  A 62-year-old man was incidentally found to have fibrous dysplasia of the temporal bone on routine computed tomography scan.
  
  
  METHODS
  One case report.
  
  
  RESULTS
  Computed tomography showed a thickening of the right temporal bone with a ground-glass appearance. The 62-year-old man opted for watchful waiting.
  
  
  CONCLUSIONS
  We have presented an asymptomatic fibrous dysplasia of the temporal bone. Mild cases may never be recognised and are found incidentally because of their slow progression.
