Is the lateral ventricle the largest?
The lateral ventricles are the largest in the series of four interconnecting fluid-filled cavities within the brain. These cavities and their interconnecting channels, constitute the cerebral ventricular system.
What is lateral ventricular enlargement?
Ventricular enlargement is a brain condition that occurs when the lateral ventricles become dilated. The most common definition uses a volume to brain index value derived from MRI and CT reconstruction of the lateral and third ventricles.
What is the normal size of lateral ventricles?
The lateral ventricular width (LVW) range for normal fetuses was 0.7 to 1.1 cm as compared with a LVW range of 1.1 to 2.7 cm for 16 fetuses with hydrocephalus diagnosed during the second trimester. In conclusion, the LVR is extremely useful in differentiating ventriculomegaly from normal ventricular size.
What are the two lateral ventricles of the brain?
Anatomical terms of neuroanatomy The lateral ventricles are the two largest ventricles of the brain and contain cerebrospinal fluid (CSF). Each cerebral hemisphere contains a lateral ventricle, known as the left or right ventricle, respectively.
How many lateral ventricles are in the brain?
2 lateral ventricles
The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).
Can ventriculomegaly be treated?
How is ventriculomegaly treated? Ventriculomegaly only needs to be treated if the baby has hydrocephalus, a build-up of cerebrospinal fluid (CSF) in the brain. Treatments for hydrocephalus include: Shunt placement: In this process a small tube is implanted in the brain while the child is under anesthesia.
Why do ventricles enlarged?
When an injury or illness alters the circulation of CSF, one or more of the ventricles becomes enlarged as CSF accumulates. In an adult, the skull is rigid and cannot expand, so the pressure in the brain may increase profoundly. Hydrocephalus is a chronic condition.
What are the right and left lateral ventricles of the brain?
Medically reviewed by Healthline’s Medical Network on April 15, 2015. The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid, a clear, watery fluid that provides cushioning for the brain while also helping to circulate nutrients and remove waste.
Why is the left ventricle thicker than the right?
Left and right ventricle collectively make the apex of the heart. Since the wall of the left ventricle is thicker than that of the right ventricle, the left ventricle pumps blood with high pressure. The main difference between the right and the left ventricle is the pressure of the blood pumped by each ventricle.
Which is the largest of the four ventricles in the brain?
Lateral ventricle (Ventriculus lateralis) The lateral ventricles are the largest in the series of four interconnecting fluid-filled cavities within the brain. These cavities and their interconnecting channels, constitute the cerebral ventricular system. The other two cavities of this system are the third and fourth ventricles,
How is the volume of the lateral ventricles measured?
The volume of the lateral ventricles, and similar structures within the brain, can be measured through a CT scan. The scan allows doctors to measure not only the size of the ventricles but also the density of the cerebrospinal fluid that they contain.
