Nail guns are used as a tool to drive a nail into hard materials with ease. Head injuries caused by nail guns are extremely rare; most cases have good clinical outcomes, while some are life-threatening. Catastrophic outcomes in penetrating nail-gun injuries caused by high-velocity devices are associated with deep brain damage, vascular injury, and delayed vascular disease causing intracranial hemorrhage. We present herein an unusual case of penetrating intracranial nail gun injury.
