In our case, a 30-year-old man presented to neurosurgery clinic with signs and symptoms of right-sided weakness after suicide bomb attack. The skull X-ray showed a single intracranial nail. Small craniotomy was done and the nail was removed with caution to avoid injury to surrounding normal brain tissue. At 6 months＇ follow-up his right- sided power improved to against gravity.展开更多
