title: Hypothalamic-pituitary dysfunction in primary empty sella syndrome in childhood.
abstract: In a series of 37 consecutive CT scans performed in children referred to our pediatric endocrine unit, an empty (eight) or partially empty (one) sella turcica was found in nine (24%) patients with short stature or delay in sexual maturation, precocious puberty, or hypoparathyroidism. The size and contour of the sella were abnormal in only three patients. Five of the nine children had evidence of decreased growth hormone secretion as determined by subnormal GH secretory responses to provocative tests (peak GH concentration less than 7 ng/ml) or assessment of endogenous 24-hour GH secretion (mean 24-hour GH concentration less than 3 ng/ml). Two children had multiple pituitary hormone deficiencies. Although primary empty sella syndrome was often associated with hypothalamic-pituitary dysfunction in this series, the prevalence of an empty sella in normal children is unknown. Further identification and evaluation of children with empty sella may provide new information regarding the cause of pituitary dysfunction in childhood.
