title: Computed tomography imaging findings of craniofacial fibrous dysplasia.
abstract: BACKGROUND
  The purpose of this study was to retrospectively describe demographic characteristics and computed tomography (CT) imaging findings of craniofacial fibrous dysplasia (FD).
  
  
  METHODS
  Between February 2010 and February 2013, we retrospectively studied 64 patients described as FD at CT imaging. Site of involvement and CT imaging findings of craniofacial FD were recorded for each patient.
  
  
  RESULTS
  Our patients are described as FD at CT imaging with the following findings: expansion, ground glass density, expansion and sclerosis, expansion with sclerosis and lytic appearance, expansion and lytic appearance, and only sclerosis. Expansion was the main feature which was seen with other findings (85%). The most common finding was ground glass density and the least appearance was expansion with lytic areas and only sclerosis.
  
  
  CONCLUSIONS
  Our study has shown that it is very effective to know about CT findings and localizations of craniofacial FD to reduce unnecessary biopsy rates and increase the true diagnosis.
