The cavum vergae (CV), along with the cavum septum pellucidum (CSP) that islies 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. ~~The~~

Terminology

The cavum vergae ~~is sometimes~~has also been referred to as the 6th ventricle ³although this usage has fallen out of favour, both because of the lack of any direct communication between the cavum vergae and the ventricular system proper and the modern vogue to standardise nomenclature.

Gross anatomy

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.

Relations

The cavum vergae has important immediate anatomical relations ³:

anteriorly: cavum septum pellucidum
posteriorly: splenium of the corpus callosum
superiorly: body of the corpus callosum
inferiorly: transverse fornix

Development

The septa of the cavum septum pellucidum atand vergae begin to fuse from posterior to anterior from approximately 24 weeks gestation. By term, the cavum vergae is closed in 97% of babies, whereas the cavum septum pellucidum persists in most at this stage⁴. 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. Because of this ordered obliteration, a cavum septum pellucidum almost always accompanies a cavum vergae ^1-2,2.
