title: Calcifying cystic odontogenic tumour: CT imaging.
abstract: OBJECTIVE
  Calcifying cystic odontogenic tumour (CCOT) is a rare disorder of the jaw. A comparison between conventional radiographs and CT images in CCOTs has not been reported. The purposes of this study were to analyse conventional radiographs and CT images of CCOTs, establish CT images of CCOTs and assess the utility of CT in the diagnosis of CCOTs.
  
  
  METHODS
  Nine patients with a histopathologically confirmed CCOT who had both conventional radiographs and CT images were enrolled.
  
  
  RESULTS
  CT was superior to conventional radiographs in detecting buccolingual expansion, odontomas and radio-opaque bodies.
  
  
  CONCLUSIONS
  The characteristic CT appearances of CCOT were that radio-opaque bodies were typically located in the periphery of the lesion and the shape of radio-opaque bodies was linear and/or spotted. CT was useful in diagnosing a CCOT.
