A 33yo man is hit by a car. He loses consciousness but is found to be fine by the paramedics.
When awaiting doctors review in the ED he suddenly becomes comatose. What is the most likely
dx?
a. SAH
b. Subdural hemorrhage
c. Intracerebral hemorrhage
d. Extradural hemorrhage
Ans. The key is D. Extradural haemorrhage. [Age 33 (younger age), considerable head trauma, and lucid
interval (present in both extradural and subdural) are the points in favour].
