Educational content only — not medical advice.
Anatomy
The septum of the telencephalon (septum pellucidum) is a thin, translucent triangular double membrane separating the anterior horns of the left and right lateral ventricles in the midline, stretched between the corpus callosum superiorly and the fornix inferiorly.
Clinical notes
Cavum septi pellucidi (fifth ventricle) is a normal developmental anatomical variant; absence of the septum pellucidum is a diagnostic hallmark of septo-optic dysplasia (de Morsier syndrome).
