title: Neurohypophyseal ectopy in growth hormone insufficiency.
abstract: Nuclear magnetic resonance imaging of the hypothalamohypophyseal tract allows the detection and identification of ectopic posterior pituitary lobe tissue by its characteristic high signal intensity. We found this anomaly in 2 boys with growth hormone insufficiency. Neurohypophyseal ectopy may be misdiagnosed as subhypothalamic tumor and such patients risk to be subjected to unnecessary neurosurgery.
