Radiological findings of transorbital penetrating intracranial injury in a child.

In penetrating injuries, woods are known to be difficult to detect with radiological imaging studies, because the wood density are known to be extremely close to the value of air on CT. Adjustment of CT window and reconstruction of a 3D image from CT images allowed us to more accurately distinguish wood from air and to find the fragment of the wooden chopstick. It is particularly useful in transorbital penetrating injury.
