Which sign is commonly associated with basilar skull fracture?

• A. Battle's sign
• B. Diplopia
• C. Nystagmus
• D. Hemiparesis

Answer: (A)

Basilar skull fractures often present with bruising around areas where the skull base is closest to soft tissues, and Battle's sign is the classic clue. This sign is bruising behind the ear over the mastoid process, signaling bleeding into the mastoid region after a base-of-skull fracture. It typically develops later, after 24 to 48 hours, but its presence strongly suggests a skull base injury. Other signs listed are not as specifically linked to basilar skull fractures. Diplopia can occur with various cranial nerve issues or orbital injuries, but it isn’t a hallmark of skull base fracture. Nystagmus points to vestibular or central issues and isn’t specific to fracture at the skull base. Hemiparesis indicates a brain injury affecting motor pathways rather than a base-of-skull fracture itself. So Battle's sign best fits the scenario.
