Abstract

Pre-operative bilateral simultaneous inferior petrosal sinus sampling with assessment of ACTH levels in the left and right sinuses and the periphery was performed in 9 patients with pituitary dependent Cushing's disease who were subsequently found at surgery to have basophil microadenomata. The novel observation of this study was the pattern of secretion of other pituitary hormones so that significant inter-sinus gradients greater than or equal to 1.4:1 were seen for beta-endorphin (2.8 +/- 1.3, mean +/- SEM), PRL (4.2 +/- 1.3) and GH (6.9 +/- 2.4) as well as for ACTH (5.1 +/- 1.1). There was no inter-sinus gradient for LH, FSH and TSH. In these 9 patients with adenomata, the correlations be..
