Which finding is distinctive for epidural hematoma?

• A. Lucid interval followed by rapid deterioration
• B. Immediate loss of consciousness with no lucid interval
• C. No signs of intracranial pressure
• D. ALOC with a lucid interval

Answer: (D)

Epidural hematoma often follows a head injury with bleeding that’s arterial in origin. The distinctive pattern is an initial loss of consciousness at the time of injury, then a period where the patient appears normal or lucid, and finally a rapid deterioration as the hematoma grows and raises intracranial pressure. This sequence—an altered level of consciousness, a lucid interval, then quick decline—best captures the hallmark trajectory of epidural hematoma. So describing it as altered level of consciousness with a lucid interval fits the typical course, because it acknowledges both the early change in mental status and the subsequent period of lucidity before deterioration. The other descriptions miss the full progression: immediate loss without a lucid interval lacks the classic later improvement and decline; no signs of intracranial pressure ignores the rapid deterioration that follows the lucid interval; and mentioning a lucid interval alone doesn’t convey the initial altered consciousness that precedes it.
