Which sign is commonly associated with a fracture of the skull base?

• A. Raccoon eyes
• B. Battle's sign
• C. Hemotympanum
• D. All of the above

Answer: (D)

A fracture of the skull base can present with several distinct signs, all of which indicate possible underlying injury to the cranial cavity. Raccoon eyes, also known as periorbital ecchymosis, often appear as dark circles around the eyes, indicating potential leakage of blood into the soft tissue surrounding the eyes, commonly associated with skull base fractures. Battle's sign refers to bruising over the mastoid process, which signifies similar cranial injuries and is a result of blood tracking from a basilar skull fracture. Hemotympanum is the presence of blood in the middle ear, usually due to fracture or disruption near the skull base, and can also indicate damage to the structures involved in hearing. Since all of these signs—raccoon eyes, Battle's sign, and hemotympanum—arise from similar mechanisms of injury and complications related to skull base fractures, they all indicate the possibility of a significant head injury and are therefore collectively associated with this condition.
