CT appearances of chronically retained wooden intraorbital foreign bodies

Identification of wooden intraorbital foreign bodies (WIOFB) is crucial for avoiding severe orbital infection. Despite careful clinical examination, W IOFB are often not recognised. We report the CT findings in chronically ret ained WIOFB. When not initially diagnosed, WIOFB create a granulomatous inf lammatory foreign-body reaction. CT demonstrates the WIOFB as a linear dens e structure surrounded by a soft-tissue mass with density similar to that o f muscle, corresponding to the foreign-body reaction.
