Does everyone have a cavum septum pellucidum?

SP is an important part of the limbic system, with prominent connections to both the medial and the basolateral limbic circuit. Disease affecting the CSP can cause symptoms either by mass effect or by disturbance of the emotional and behavioral functions of the limbic system.
What is absence of the septum pellucidum?
