What is a saccular aneurysm definition?
Saccular aneurysms, also called “berry” aneurysms because they look like berries, are the most common type of brain aneurysm. 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.

Chronic headache or head pain (mainly ruptured aneurysms) Concentration headaches. Vision deficits: partial or complete blindness, or peripheral vision deficits. Cognitive problems (such as short-term memory difficulties, decreased concentration, perception problems)
What are Saccular glands?
Alveolar glands have a saclike secretory portion, and are also termed saccular glands. They typically have an enlarged lumen (cavity), hence the name similar to alveoli, the very small air sacs in the lungs. Some sources draw a clear distinction between acinar and alveolar glands, based upon the size of the lumen.
What causes a pseudoaneurysm?
A pseudoaneurysm, or pseudoaneurysm of the vessels, occurs when a blood vessel wall is injured and the leaking blood collects in the surrounding tissue. It is sometimes called a false aneurysm. In a true aneurysm, the artery or vessel weakens and bulges, sometimes forming a blood-filled sac.
What is the cause of most subarachnoid hemorrhages?
A subarachnoid haemorrhage is most often caused by a burst blood vessel in the brain (a ruptured brain aneurysm). A brain aneurysm is a bulge in a blood vessel caused by a weakness in the blood vessel wall, usually at a point where the vessel branches off.
Can brain aneurysm go away?
Aneurysms develop over a lifetime,” he says. “Another is that an aneurysm can disappear or heal itself. This is very rare and only happens in aneurysms that are considered benign because the flow of blood is so slow it eventually forms a clot and seals off the bulge.”
