Two cases of cervical injury caused by metallic foreign bodies during mowing were treated. One foreign body was the edge of a grass cutter, and the other was a metal wire. Plain-radiograph detected the foreign bodies clearly, but it was difficult to clarify the relationship of the foreign bodies with anatomical structures. Computed tomography (CT) was useful to clarify the relationship, but the shape of both foreign bodies could not be identified by the metal artifact. By combining two imaging methods, we detected the anatomical positions and shapes of the foreign bodies without any complications.
