title: Aspects of an ovarian osteoma on magnetic resonance imaging and computerized tomography.
abstract: OBJECTIVE
  To describe the contribution of magnetic resonance imaging (MRI) and computerized tomography (CT) scan to the diagnosis of an ovarian osteoma.
  
  
  METHODS
  Descriptive case study.
  
  
  METHODS
  Tertiary care center, Hôpital Tenon, Assistance Publique des Hôpitaux de Paris, University Pierre et Marie Curie, Paris, France.
  
  
  METHODS
  A 29-year-old woman with a left-sided calcified ovarian tumor on MRI and CT scan, suggesting an ovarian osteoma.
  
  
  METHODS
  Surgical removal of a 64-mm primary ovarian osteoma, exclusively by the vaginal route.
  
  
  METHODS
  The MRI and CT scan findings.
  
  
  RESULTS
  Histologic examination showed an ovarian osteoma characterized by mature bone tissue, with no signs of malignancy.
  
  
  CONCLUSIONS
  Ovarian osteoma can be adequately diagnosed by MRI or CT scan and can be treated conservatively.
