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, WIOFB are often not recognised. We report the CT findings in chronically retained WIOFB. When not initially diagnosed, WIOFB create a granulomatous inflammatory foreign-body reaction. CT demonstrates the WIOFB as a linear dense structure surrounded by a soft-tissue mass with density similar to that of muscle, corresponding to the foreign-body reaction.
