During development, these spaces obliterate posteroanteriorly - the cavum vergae followed by the cavum septum pellucidum - and it is not uncommon that both occur together as one contiguous space, aptly termed "cavum septum pellucidum (or septi pellucidi) et vergae".

      History and etymology

      Cavum septum pellucidum is a Latin term deriving from 'cavum', meaning 'space', 'septum', meaning 'fence', and therefore a dividing structure, and 'pellucidus' meaning 'transparent'.

      It has been loosely associated with 3-5,7:

      Historically it has also been called the fifth ventricle, but this use is now advised against as the cavum does not usually have any direct communication with the ventricular system.

      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.
