Usefulness of gradient-echo T2*-weighted MR imaging in evaluation of transorbital penetrating cerebral injury

Transorbital penetrating cerebral injury can cause severe morbidity if not identified and treated. After the removal of the object and without the clinical information, even the chance of suspicion of penetrating cerebral injury might be missed in the first investigation. We report a case of transorbital penetrating cerebral injury caused by a metal rod and diagnosed by MRI including gradient-echo T2*-weighted imaging.
