Peer Review Status: Internally Peer Reviewed

The cavum vergae is the posterior extension of the cavum septi pellucidi. It is also called the sixth ventricle, which is a misnomer because the cavum does not contain cerebrospinal fluid nor is it lined by ependyma.

The cavity was first described by the Italian anatomist, Andrea Verga, in 1851. It may exist as a separate cavity rather than communicating with the cavum septi pellucidi. The incidence of the cavum vergae was 2.3% in 1032 brains.

Verga's ventricle is present in 1-9% of human brains and was described by Verga in 1851 according to Lang (1983).
