The septum pellucidum normally has a cavity of 1 to 2mm in width. When this cavity is larger, it is called cavum septi pellucidi or fifth ventricle. The term fifth ventricle is a misnomer because unlike ventricular cavities it does not contain cerebrospinal fluid nor is it lined by ependyma. The incidence of cavum septi pellucidi was 20.3% in 1032 brains studied.

The cavurn septi pellucidi varies from 2 to 95% depending to author; it is more prevalent in the young (infants) than older adults. The extreme differences in the reported frequency is highly suspect.
