What is a cavum septum pellucidum and Vergae?
Cavum septum pellucidum (CSP) is a normal variant, it is a midline CSF containing structure separating the two anterior horns of the lateral ventricle. Cavum vergae (CV) is a posterior extension of the CSP, posterior to the anterior columns of the fornix.
Is cavum septum Vergae normal?
Cavum Vergae is a normal anatomic variant, and is the posterior extension of a Cavum Septum Pellucidum, another normal anatomic variant. The cavity was first described by the Italian anatomist, Andrea Verga, in 1851. It may exist as a separate cavity, or may communicate with the Cavum Septum Pellucidum.
How common is cavum vergae?

What is a fetal cavum vergae?
► prenatal diagnosis. Abstract. Cavum vergae (CV) cysts are developmental cysts of the midline of the brain that is. formed from the posterior extension of the cavum septum pellucidum.
What does Pellucidum mean?
Order NINDS Publications. Definition. The septum pellucidum (SP) is a thin membrane located at the midline of the brain between the two cerebral hemispheres, or halves of the brain. It is connected to the corpus callosum — a collection of nerve fibers that connect the cerebral hemispheres.
Why is septum important?
The septum separates the atria and ventricles in such a way that it forms a barrier between the heart chambers and this prevents mixing of oxygenated and deoxygenated blood.
What is the cavum vergae?
Cavum vergae is a midline cavity of the brain, posterior to the septum pellucidum which often communicates with a cavum septum pellucidum.
Is cavum septum pellucidum associated with lower brain volume and cognitive performance?
SYNOPSIS: A cohort study assessing participants from the Professional Fighters Brain Health Study found that the presence of cavum septum pellucidum and cavum vergae is associated with lower regional brain volumes and lower cognitive performance.
What is the difference between cavum septum and cavum Vergae?
By term, the cavum vergae is closed in 97% of babies, whereas the cavum septum pellucidum persists in most at this stage 4. Cavum septum pellucidum closure to form a single septum pellucidum occurs by 6 months of age in 85% of cases but may persist to adulthood in 15% 3 .

Thirty-six percent to 50% of term babies have cavum septi pellucidi by CT and ultrasound ( 39 ), whereas up to 85% have cavum septi pellucidi by autopsy studies ( 06 ).
What is the cavum Vergae (CV)?
The cavum vergae (CV), along with the cavum septum pellucidum (CSP) that lies immediately anterior to it, is a persistence of the embryological fluid-filled space between the leaflets of the septum pellucidum and is a common anatomical variant .
