Aneurysm, brain"An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word ""aneurysm"" comes from the Greek ""aneurysma"" meaning ""a widening."" A brain aneurysm is a small aneurysm that looks like a berry and classically occurs at the point at which a cerebral artery departs from the circular artery (the circle of Willis) at the base of the brain. Brain aneurysms rupture frequently and bleed. Also called a berry aneurysm."
RELATED TERMS--------------------------------------
Aneurysm
A weakness in the blood vessel wall that balloons out and may rupture at some point. Aneurysms rarely cause symptoms before the rupture, unless they are large. They do not mimic the symptoms of migraine or cluster headache. It is vital to discover them before they rupture and have catastrophic consequences such as paralysis or death.
Artery
A blood vessel that carries blood from the heart to the body.
Vein
A blood vessel that carries blood from the body back into the heart.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Rupture
A break or tear in any organ or soft tissue.
Brain
"That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called ""hemispheres."" "
Cerebral
Referring to the cerebrum.
Base
A chemical compound that either donates hydroxide ions or absorbs hydrogen ions when dissolved in water. Bases and acids are referred to as opposites because the effect of an acid is to increase the hydronium ion concentration in water, whereas bases reduce this concentration. Arrhenius bases are water-soluble and always have a pH greater than 7 in solution.
SIMILAR TERMS--------------------------------------
Aneuploidy
One or a few chromosomes above or below the normal chromosome number. For example, three number 21 chromosomes or trisomy 21 (characteristic of Down syndrome) is a form of aneuploidy.
Aneurysm
A weakness in the blood vessel wall that balloons out and may rupture at some point. Aneurysms rarely cause symptoms before the rupture, unless they are large. They do not mimic the symptoms of migraine or cluster headache. It is vital to discover them before they rupture and have catastrophic consequences such as paralysis or death.
Aneurysm, abdominal
"An aneurysm situated within the abdomen (belly). An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word ""aneurysm"" comes from the Greek ""aneurysma"" meaning ""a widening."" See: Aneurysm, aortic."
Aneurysm, aortic

Aneurysm, arterial
"An aneurysm involving an artery. As opposed to a venous aneurysm or a cardiac aneurysm. An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word ""aneurysm"" comes from the Greek ""aneurysma"" meaning ""a widening."""

Aneurysm, berry
A berry aneurysm is a small outpouching (aneurysm) that looks like a berry and classically occurs at the point at which a cerebral artery departs from the circular artery (the circle of Willis) at the base of the brain. Berry aneurysms often rupture and bleed. Also called a brain aneurysm. An aneurysm is a localized dilatation (widening) of a blood vessel (an artery or a vein) or the heart. At the area of the aneurysm, the wall is weakened, bulging, and at risk of rupture (breaking).
Aneurysm, cardiac
"Outpouching of an abnormally thin portion of the heart wall. An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word ""aneurysm"" comes from the Greek ""aneurysma"" meaning ""a widening."" Heart aneurysms tend to involve the left ventricle because the blood there is under greatest pressure."
Aneurysm, fusiform
"An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word ""aneurysm"" comes from the Greek ""aneurysma"" meaning ""a widening."" A fusiform aneurysm is shaped like a spindle. A fusiform widening of an artery or vein. The word ""fusiform"" comes from the Latin ""fusus"" meaning ""spindle."""

The word ""aneurysm"" comes from the Greek ""aneurysma"" meaning ""a widening."" A miliary aneurysm is tiny like a millet seed. (Millet is a cereal grass. Its seed is about 2 millimeters in diameter). Miliary aneurysms tend to affect minute arteries in the brain and, in the eye, the retina."
Aneurysm, racemose
"An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture.
