title: The sella turcica in primary end organ failure.
abstract: Pituitary hyperplasia, or adenoma, may result from end or target organ failure as seen in primary hypothyroidism and hypogonadism. Associated enlargement of the sella turcica and contour alterations without significant increase in volume may be seen. A review was made of 12 patients with end organ failure demonstrating the spectrum of radiologic changes within the sella turcica. Recognition of pituitary enlargement resulting from end organ failure may eliminate unnecessary surgery.
