AbstractA rare case of penetrating head injury caused by a nail-gun was described. A 24-year-old male was admitted to our hospital due to head injury. He had handled a nail-gun at a construction site. On admission the patient was fully conscious with no neurological defects. A small wound was observed at the left front-temporal region. Skull films showed a large nail embedded in the skull cavity. A computed tomographic (CT) scan, changing level of window, demonstrated intracerebral hematoma, fragment of skull bone and nail. Cerebral angiography (CAG) showed extravasation at the left frontal region. Emergency operation was performed and his recovery was uneventful. Twenty-two craniocerebral injuries caused by nail-guns have been reported in world medical literature but this was the first report in Japan. The characteristics of craniocerebral nail-gun injuries were less damage and better prognosis compared with gunshot injuries. However intracranial infection and vascular injury were possible lethal complications. In this case, preoperative examination, such as CT scan and CAG was valuable and the early operation for the sake of safety was very effective.
