At autopsy, the first patient had optic nerve aplasia, a normal pituitary gland, and some disorganization of myelinated fibers in the hypothalamus. The second patient had a normal thyrotropin and prolactin response to thyrotropin-releasing hormone, plus hyperphagia, deranged thirst mechanism, and temperature instability. These findings suggest that the lesion may be a defective hypothalamic regulation of pituitary hormone secretion. Congenital or traumatic hypothalamic-pituitary lesions may not affect all releasing factors or trophic hormones in a similar fashion.(Am J Dis Child 133:739-742, 1979)
