berry aneurysm (brain aneurysm) a small saccular aneurysm of a cerebral artery, usually at the junction of vessels in the circle of Willis; such aneurysms frequently rupture, causing subarachnoid hemorrhage. Called also cerebral aneurysm. Abdominal aortic aneurysms are defined by a > 50% focal dilation of the abdominal aorta or when the abdominal aortic diameter is > 3 cm. 1-3 Aneurysms can be further classified into the more common fusiform subcategory (accounting for 80% of cases), or the rarer saccular type.

Saccular aneurysms have a “neck” that connects the aneurysm to its main (“parent”) artery and a larger, rounded area called the dome. These aneurysms bulge on only one side of the artery wall. Saccular aneurysms are histologically characterized by disruption of the internal elastic lamina at the entrance site/neck of the aneurysm. The histopathologic features of the intima, media, and adventitia are the prime determinants of aneurysm natural history. Also important to recognize are indentations on the upper dome of the aneurysm (purple and red arrows), marking location of the distal dural ring, where the aneurysm expands through the ring into the intradural space — as most large/giant cavernous aneurysms eventually do.

The most common site for an arterial aneurysm is the abdominal aorta.
While aneurysms may occur anywhere in the body, the most likely locations are the cerebrum, or brain, and the aorta, a large blood vessel that travels from the left ventricle of the heart, through the chest, carrying blood to the vital organs.

Most are located on or near the circle of Willis. Se hela listan på radiopaedia.org Saccular Aneurysms. Saccular aneurysms occur immediately distal to a branch point in the cerebral vasculature. They tend to be roughly spherical and point in the direction of the blood flow (Figure 1 ).
The most common type of cerebral aneurysm is called a saccular, or berry, aneurysm, occurring in 90 percent of cerebral aneurysms. This type of aneurysm looks like a "berry" with a narrow stem.
