Tangential gunshots to the head are a special type of injury in which the bullet or bullet fragments do not penetrate the inner table of the skull. Most of patients experiencing this kind of injuries usually have a benign clinical presentation. We describe the case of a 22-year-old soldier who had a tangential gunshot to the head caused by a high-velocity projectile. Initially, the patient was neurologically intact, progressing to profound coma in the next 2 hours. The characteristics of the wound and initial neurologic condition led to first contact physicians to treat this injury as a case of mild head trauma. This case shows us that gunshots to the head caused by high-velocity missiles must be treated aggressively like a severe head injury, even when the initial neurologic examination is normal.
