The septum pellucidum (SP) is a thin membrane located at the midline of the brain. Children who are born without this membraine and also have other abnormalities--pituitary deficiencies and abnormal development of the optic disk--have a disorder known as septo-optic dysplasia. More information about this condition can be located at the NINDS Septo-Optic Dysplasia Information Page.
The absence of the septum pellucidum alone is not a disorder. However, when it is part of septo-optic dysplasia the prognosis
varies according to the presence and severity of associated symptoms.
