Which intracranial bleed is often associated with fracture of the temporal bone?

• A. Concussion
• B. Brain herniation
• C. Epidural hematoma
• D. Subdural hematoma

Answer: (C)

Epidural hematoma is classically linked to a temporal bone fracture because such a fracture often lacerates the middle meningeal artery, causing a rapid arterial bleed between the skull and the dura. This type of bleed tends to form a lens-shaped (biconvex) collection on imaging and can progress quickly after a brief period of apparent recovery (lucid interval), making it a key association with temporal bone injury.

Concussion is a functional brain injury without a discrete intracranial bleed and doesn’t reflect a vascular injury from a fracture. Brain herniation is a dangerous consequence of rising intracranial pressure from any expanding lesion, not a specific fracture-associated bleed. Subdural hematoma results from tearing of bridging veins and is more commonly linked to diffuse brain injury or elderly atrophy, with a crescent-shaped collection that crosses sutures, rather than the classic temporal bone fracture scenario.
