Which intracranial bleed typically presents with the most rapid onset after head trauma?

• A. Epidural hematoma
• B. Subdural hematoma
• C. Intracerebral hematoma
• D. Subarachnoid hemorrhage

Answer: (A)

An epidural hematoma presents most rapidly after head trauma because it is an arterial bleed between the skull and dura. The middle meningeal artery, when torn, dumps high-pressure blood into that space quickly, causing a rapid rise in intracranial pressure and swift neurological deterioration (often after a brief loss of consciousness followed by a lucid interval). In contrast, subdural hematomas involve venous bleeding from bridging veins and tend to accumulate more slowly, intracerebral hematomas bleed into brain tissue with variable and often slower onset, and subarachnoid hemorrhage can be sudden but is not the classic rapid progression pattern seen with an arterial epidural bleed.
