Background: Penetrating brain injury (PBI) caused by a nail gun is an extremely rare neurosurgical emergency that poses a challenge for neurosurgeons because of its rarity and complexity.
Case description: Here we present 3 cases of PBI caused by a nail gun. In the first case, the nail entered through the right parietal bone and lodged in the right parietal lobe and basal ganglia. In the second case, the nail entered through the right occipital bone and lodged in the right occipital lobe. In the third case, the nail entered through the right parietal bone and lodged in the right frontal and parietal lobes. All patients underwent surgical removal of the nail. The first patient presented with reduced left-side strength, whereas the second and third patients were neurologically intact on presentation.
Conclusions: PBI caused by a nail gun can present with differing clinical manifestations, and most cases require immediate surgery. A rational management strategy should provide a good postoperative prognosis with minimal neurologic deficits in these patients.
