Battle sign and raccoon eyes indicate what underlying injury?

Battle sign and raccoon eyes point to a basilar skull fracture, a break at the base of the skull, often involving the temporal bone. The bruising behind the ear (Battle sign) and around the eyes (raccoon eyes) happens because blood tracks into the soft tissues of the skull base after injury. This pattern is more specific for skull-base injury than for a generic skull fracture and raises concern for potential complications such as CSF leakage, meningitis, or cranial nerve injuries. By contrast, an epidural hematoma usually starts with a brief loss of consciousness followed by a lucid interval and rapid decline, while a subarachnoid hemorrhage typically presents with a sudden, severe thunderclap headache and meningismus rather than these ecchymoses.
