What is the difference between 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 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.
What is the cavum septum pellucidum?
The cavum septum pellucidum (CSP) is a potential cavity between the membranous leaves of the septum pellucidum, separated by at least 1 mm, and is considered a normal anatomical variation.
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 does the septum pellucidum do 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 does cavum mean?
anatomical recess or hollow
Medical Definition of cavum : an anatomical recess or hollow: as. a : the lower part of the concha of the ear adjoining the origin of the helix. b : the nasal cavity.
Does everyone have cavum septum pellucidum?
Epidemiology. A cavum septum pellucidum is present in the normal fetus, but over 85% of them fuse by 3-6 months of age meaning that a cavum septum pellucidum persists in ~15% of the adult population.
What is the cavum?

What are symptoms of CSP?
A CSP cyst can present with a myriad of symptoms, including headache, focal neurological deficits, ataxia, seizures, papilledema, emesis, syncope, visual, and even sensorimotor findings. Gradually expanding cysts may even present with visual, behavioral, or autonomic symptoms.
What is the prevalence of a cavum septum pellucidum?
A cavum septum pellucidum is present in the normal fetus, but over 85% of them fuse by 3-6 months of age meaning that a cavum septum pellucidum persists in ~15% of the adult population. Gross anatomy The cavum septum pellucidum commonly occurs, and is often confused with the cavum vergae , which is situated posterior to the anterior columns of
Is the cavum Vergae anterior or posterior to the fornix?
The cavum vergae is the posterior extension of the cavum septum pellucidum, posterior to the anterior columns of the fornix, lying anterior to the splenium of the corpus callosum, but it may exist independently 1-3. The cavum vergae has important immediate anatomical relations 3: anteriorly: cavum septum pellucidum.
What is the difference between the cavum septum and cavum Vergae?
Gross anatomy. The cavum septum pellucidum commonly occurs, and is often confused with the cavum vergae, which is situated posterior to the anterior columns of the fornix. During development, these spaces obliterate posteroanteriorly – the cavum vergae followed by the cavum septum pellucidum – and it is not uncommon that both occur together.
