One of the pathologic consequences of an unruptured cerebral aneurysm is that it can

a. shunt blood away from the surrounding tissues.
b. leak blood into the subarachnoid space.
c. damage the middle layer of the arterial wall.
d. place pressure on the surrounding tissues.


D
An unruptured aneurysm may be problematic because it places pressure on the surrounding tissues. The aneurysm becomes clinically significant when the vessel wall becomes so thin that it ruptures, sending arterial blood at a high pressure into the subarachnoid space.
