title: Fibro-osseous lesion of the cranium in an adolescent patient.
abstract: BACKGROUND
  Fibrous dysplasia, ossifying fibroma, and desmoplastic fibroma are rare benign calvarial lesions, which can have local aggressive behavior. These tumors can present with similar clinical and radiologic characteristics making diagnosis difficult at times.
  
  
  METHODS
  A 16-year-old male presents after noting an indentation of his skull. Comparison with current and previous imaging revealed progressive erosion of the skull underlying the indentation.
  
  
  CONCLUSIONS
  Fibrous dysplasia, ossifying fibroma, and desmoplastic fibroma are rare fibro-osseous tumors with similar characteristics radiographically. Accurate diagnosis of these tumors can be difficult even with the combination of clinical presentation, imaging, and pathology. The treatment of choice is resection and cranial reconstruction, if necessary, with close follow-up as recurrence can occur.
