title: Pneumo-orbital cyst after orbital fracture repair.
abstract: OBJECTIVE
  To report a case of a respiratory epithelial-lined, air-filled orbital cyst as a late complication of orbital fracture repair.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  Recurrent episodes of diplopia and hyperophthalmia developed secondary to pneumatic inflation of a respiratory epithelial-lined orbital cyst 6 months after orbital fracture repair. This cyst remained in communication with an ethmoidal air cell and became inflated during pressurization of the ethmoid sinus. Removal of the cyst and orbital implant was curative.
  
  
  CONCLUSIONS
  Air-filled, respiratory epithelial-lined orbital cyst is a rare cause of episodic diplopia and globe displacement after orbital trauma.
