title: Simultaneous ipsilateral temporal fossa and orbital dermoid cysts.
abstract: OBJECTIVE
  To describe a case of simultaneous dermoid cysts in the lateral orbit and temporal fossa.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  A 7-year-old boy with a lateral orbital mass and infratemporal fossa mass underwent computed tomography and surgical excision.
  
  
  RESULTS
  Intraoperatively, two distinct cystic lesions were identified. The orbital lesion extended just beneath the lateral rim. The temporal fossa lesion extended posteriorly along the temporal fossa. No bony defect in the lateral orbital wall was identified, and each distinct lesion was completely excised.
  
  
  CONCLUSIONS
  To our knowledge, this is the first reported case of multiple dermoid cysts in the orbital region. When imaging studies demonstrate separate cystic lesions and do not reveal a bony defect in the lateral orbital wall, multiple lesions should be suspected.
