Abstract

To determine whether posterior pituitary ectopia in children with optic nerve hypoplasia has a male predominance or an increased incidence of breech delivery. Retrospective analysis of 12 children with optic nerve hypoplasia and posterior pituitary ectopia. Eleven of 12 patients with posterior pituitary ectopia were boys. No child had a history of breech delivery. Two children had a history of breech positioning but were delivered by cesarean section. Posterior pituitary ectopia with optic nerve hypoplasia shows a strong male predominance but no association with breech delivery.
