Which aneurysm type is also known as a berry aneurysm?

Explanation:
Berry (saccular) aneurysm refers to a small, sac-like outpouching of a cerebral artery, usually at a branch point in the circle of Willis, with a narrow neck. This morphology distinguishes it from other aneurysm types. Fusiform dilation involves a circumferential, spindle-shaped widening of the entire vessel. Dissection means a tear in the vessel wall with blood creating a false channel within the wall. Pseudoaneurysm is a contained rupture where blood is walled off outside the normal arterial wall layers. So the berry-shaped, sack-like form is the saccular aneurysm, making it the correct choice.
