Better Localization of Periorbital or Intraorbital Foreign Body with Reconstructed Three-Dimensional Computer Tomography-Case Report

Purpose: To report a novel medical imaging technique valuable in the differentiation of a patient with eyelid foreign body that could be mistaken as an intraorbital foreign body by conventional computer tomography (CT). Method: Case report Result: A 50-year-old male patient suffered from falling face down during work. A metallic foreign body in the medial aspect of right orbit was found by conventional CT. Further computer-assisted three-dimensional CT (3D CT) images revealed subdermal foreign body in the upper eyelid. The foreign body was removed smoothly through small skin incision. Conclusion: With the help of 3D CT images, precise localization of periorbital or intraorbital foreign body could be possible.
