Adult expression of DeMorsier syndrome following head trauma

DeMorsier syndrome is a well-described entity, which includes optic nerve hypoplasia and absence of the septum pellucidum with or without pituitary abnormalities. Patients with all three aspects of this syndrome are diagnosed in childhood due to their neuroendocrine dysfunction. We present a review of the literature and a case report of an adult diagnosed with DeMorsier syndrome when he developed neuroendocrine abnormalities after head trauma.
