title: Bilateral symmetrical epibulbar osseous choristoma.
abstract: OBJECTIVE
  To report a patient with bilateral symmetrical epibulbar osseous choristoma.
  
  
  METHODS
  Retrospective observational case report.
  
  
  METHODS
  One patient with bilateral symmetrical epibulbar osseous choristoma.
  
  
  METHODS
  Retrospective review of stored office records, photographs, computed tomography (CT), and histopathological findings.
  
  
  METHODS
  Appearance of the choristoma, CT, and histopathological findings.
  
  
  RESULTS
  A 6-year-old female had bilateral superotemporal subconjunctival masses. Surgical excision was performed bilaterally. The lesions were encapsulated and attached to the sclera, and consisted histopathologically of epibulbar osseous choristoma.
  
  
  CONCLUSIONS
  We report the first case of bilateral symmetrical epibulbar osseous choristoma without other associated choristomas. Preoperative CT imaging is helpful in assessing the extent of the tumor and planning surgery.
