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?
A cavum septi pellucidi and cavum vergae were found together in 19 of 249 (7.6%). We interpret these data as showing that the cavum septi pellucidi is rarely seen in normal individuals although the cavum vergae is seen with the same frequency in normal and retarded populations.
What is cavum vergae fetal ultrasound?
The cavum septum pellucidum is a fluid-filled cavity located between the membranes of the septi pellucidi, which should always be visualized sonographically in normal fetuses between 18 and 37 weeks gestation and in approximately 50% of term infants.
What is prominent cavum vergae?
Cavum vergae is a midline cavity of the brain, posterior to the septum pellucidum which often communicates with a cavum septum pellucidum. While the clinical significance of this anatomic finding is not clear, we have seen 6 pediatric patients with cavum vergae who had neurologic abnormalities.
What is cavum septum et Vergae?
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.
What is the function of the septum pellucidum in the brain?
The septum pellucidum acts as a partition between a portion of the lateral ventricles, forming part of the walls of the anterior region of the lateral ventricles. It is made up of a thin two-layered structure that consists of white matter, some neurons, fiber bundles, and blood vessels.
What is incidental Cavum Vergae?
The cavum septum pellucidum is a normal anatomic variant, is usually asymptomatic and discovered incidentally. Cavum vergae is the term assigned to the posterior extension of the CSP. In more than 85% of cases, the CSP fuses by three to six months of life.
Is Cavum Vergae normal in fetus?
Does the presence of cavum septum pellucidum affect brain function?
Dr. Sethi reports no financial relationships relevant to this field of study. 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 the cavum septi pellucidi and cavum Vergae?
The cavum septi pellucidi is bordered posteriorly by the column of the fornix. The cavum Vergae is bordered anteriorly by the posterior border of the cavum septi pellucid, inferiorly by the body of the fornix, and superiorly and posteriorly by the corpus callosum. Anatomically, the 2 cavities are not separated.
What does delayed closure of the cavum septum pellucidum indicate?
Delay of the normal closure of the cavum septum pellucidum may be a first warning sign in routine ultrasound studies of the fetal brain. In this way, abnormalities of the cavities, mostly by size, may indicate the need for further examinations. The size of the cavum septum pellucidum after birth varies considerably.
What forms the lateral leaves of the cavum septum pellucidum?
The lateral leaves of the cavum septum pellucidum are formed by the medial hemispheric walls, which fuse later in development. In the normal development of the cava and in cysts of the cava, this space is not in communication with the ventricular system.
