title: Chiasmal syndrome caused by pituitary-sellar disproportion.
abstract: A patient with pituitary-sellar disproportion, a perichiasmal visual field defect, and no clinically demonstrable endocrinopathy is presented. Radiographic and pathologic studies suggested that the pituitary-sellar disproportion was secondary to sellar hypoplasia, a previously unrecognized cause of the chiasmal syndrome. It remains to be seen whether hormonal manipulation aimed at suppression of gonadotropin- and/or prolactin-secreting cells might obviate the need for exploration in patients similar to ours.
