Which term describes the midline fluid-filled space between the leaves of the septum pellucidum?

Cavum septum pellucidum is the midline, fluid-filled space between the leaves of the septum pellucidum. It’s a normal developmental space that appears during fetal life and often fuses, but can persist in some individuals into adulthood as a harmless variant or also be seen with other midline brain anomalies. On imaging, it shows up as a CSF-filled gap along the central alignment of the brain. The other structures mentioned are different CSF pathways or cavities: the cerebral aqueduct is the narrow channel connecting the third and fourth ventricles; the interventricular foramen is the opening (foramen of Monro) that allows CSF flow from each lateral ventricle to the third ventricle; and the third ventricle is the single midline ventricle between the thalami. Thus, the term that describes the space between the leaves of the septum pellucidum is Cavum Septum Pellucidum.
