[An orbitocranial foreign body. Diagnostic reflections].

The authors demonstrate how a delay in diagnosis, in the case of an orbito-cranial foreign body, serves to underscore importance of CT in even minor, orbito-facial injuries, when there is some suspicion of intracranial penetration. This examination, which should be requested as soon as possible in such cases, usually permits detection of the intracranial foreign body. However, if the image is much clearer than those of conventional X-rays, it can in certain cases, remain a matter of subtle interpretation, particularly in cases of less dense materials such as wood.
