Battle's sign is best described as?

Battle's sign points to a basilar skull fracture, typically involving the temporal bone. It shows up as bruising behind the ear over the mastoid process and often appears hours to a day or two after the injury. This late sign indicates significant trauma and prompts you to treat the patient as having a skull-base fracture, with careful monitoring for complications like intracranial injury. Bruising in other locations (palm, shin, or under the eye) isn’t the hallmark of this condition, so the bruising behind the ear is the key indicator.
