Answer to Question 1

ANS: B
A lacunar stroke is associated with occlusion of a single, deep perforating artery that supplies small penetrating subcortical vessels, causing ischemic lesions, not an embolus, hemorrhage, or aneurysm.

Answer to Question 2

ANS: B
Saccular aneurysms (berry aneurysms) occur frequently (in approximately 2 of the population) and likely result from congenital abnormalities in the media of the arterial wall and degenerative changes. Fusiform aneurysms (giant aneurysms) occur as a result of diffuse arteriosclerotic changes and are found most commonly in the basilar arteries or terminal portions of the internal carotid arteries. Arteriovenous malformation (AVM) is a tangled mass of dilated blood vessels creating abnormal channels between the arterial and venous systems. Thrombotic stroke would show signs of necrotic tissue, not degenerative changes.
