Neurohypophyseal ectopy in growth hormone insufficiency.
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.
