These CT scans are of the skull of a girl taken when she turned her horse out. The girl wasn't a novice horse owner and the horse wasn't considered dangerous in any way. In his excitement at being turned out he bucked and accidentally kicked her in the head. Wearing a helmet would have prevented this injury.
Think Ahead: Wear a hat around horses.
