Ectopic neurohypophysis in neonate

MRI, T1 in sagittal plane, of ectopic neurohypophysis in 3-day old neonate born at 37 weeks by caesarean section. This lesion was not identified in a fetal MRI performed at 25 weeks’ gestation. This infant also has bilateral periventricular nodular heterotopia, agenesis of corpus callosum, colpocephaly, hypoplastic optic nerves, and Dandy-Walker malformation. At 3 years of age, the child had epilepsy controlled by medications and was globally developmentally delayed. (Contributed by Dr. Xing-Chang Wei.)
