CT Scan of self inflicted gunshot wound to the head with the entrance and exit wounds clearly visible!

The ER doctor assumed the bullet was a .38. Gunshot wounds to the head are difficult to predict. Think of the skull as a closed box that cradles the brain. There isn't a lot of room for movement fo the brain or swelling in the skull. If a bullet enters the head and bounces around, the permanent cavity (bullet track) may be large, but the damage from the temporary cavity that forms is even worse. There is no room for the brain to move and the shock waves often cause irreversible damage. For some lucky people, if the bullet velocity is high and there is no side to side movement (wobble) and it passes through non-critical parts of the brain, less damage occurs and survival is possible.Photo credit @kevinabdon
