Intraorbital wooden foreign body (IOFB): mimicking air on CT

We report the case of a 41-year-old man who presented to the ER following a fall in his back garden during which he sustained a left orbital injury. Computed tomography (CT) demonstrated an intraorbital linear lucency surrounded by haziness in the intraconal fat. An intraocular wooden twig was confirmed during subsequent surgery. The possibility of a wooden intraorbital foreign body should be strongly suspected following orbital trauma when there is intraorbital density below that of the surrounding intraorbital fat on CT, as this may mimic organic foreign bodies.
