These same features are also seen in some babies who have suffered trauma, such as falls or motor-vehicle accidents. Yet many babies with these symptoms have no history or medical evidence of trauma (such as fractures, abrasions, or bruises), physical abuse, or neglect.
同样的特征也见于一些受伤的婴儿，如坠落或车祸。但许多存在这西症候的婴儿并无外伤（如骨折、擦伤或撞击）、身体虐待或被忽视的历史或医学证据。
