title: Psammomatoid and trabecular juvenile ossifying fibroma: two distinct radiologic entities.
abstract: OBJECTIVE
  Evaluate and compare the radiologic features of psammomatoid versus trabecular variants of juvenile ossifying fibromas.
  
  
  METHODS
  Twelve of fifteen cases of juvenile ossifying fibroma of the craniofacial bones, retrieved from our pathology archives for the period between 2002 and 2013, had available preoperative computed tomography (CT) scans. The radiologic features of each case were analyzed and compared by two neuroradiologists and one oral and maxillofacial radiologist, each blinded to the histopathologic diagnosis.
  
  
  RESULTS
  Juvenile psammomatoid ossifying fibroma (JPOF) exhibited a ground-glass pattern, as an outer mantle with central radiolucency, a single mural nodule, or a solid homogeneous mass. The trabecular variant presented as a radiolucent lesion with irregular, scattered calcifications. Both variants displayed a well-defined border.
  
  
  CONCLUSIONS
  This study demonstrates that psammomatoid and trabecular juvenile ossifying fibromas exhibit unique radiologic features that allow for distinction between the two variants on CT studies.
