Saccular aneurysms have a "neck" that connects the aneurysm to its main ("parent") artery and a larger, rounded area called the dome. fusiform aneurysm radiology. The circumferential arterial dilatation results from pathological involvement of the entire artery. A pseudoaneurysm, or false aneurysm, is an enlargement of only the outer layer of the blood vessel wall. The bulging aneurysm can put pressure on a nerve or the surrounding brain tissue.

A true aneurysm has all the three layers of the arterial wall (intima, media, and adventitia). Often there are no symptoms, but a ruptured aneurysm can lead to fatal complications. The three different types of aneurysms: Fusiform, saccular, and pseudoaneurysm. It may also leak or rupture, spilling blood into the surrounding tissue. These aneurysms bulge on only one side of the artery wall. This may cause a ballooning out on one side of the artery wall or it may block off or obstruct blood flow through the artery. Large dissecting aneurysm, fusiform, was encountered in the distal right vertebral artery incorporating PICA origin. The infection weakens the artery wall, causing a bulging aneurysm to form.
