  • Title: Peripheral and adrenal venous levels of steroids in a patient with virilizing adrenal adenoma.
    Author: Granoff AB, Abraham GE.
    Journal: Obstet Gynecol; 1979 Jan; 53(1):111-5. PubMed ID: 215946.
    Abstract:
    The peripheral levels of 17-hydroxypregnenolone (17delta5P), progesterone (P), 17-hydroxyprogesterone (17P), testosterone (T), 5alpha-dihydrotestosterone (DHT), androstenedione (A), androst-5-ene-3beta,17beta-diol (delts5diol), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), estradiol-17beta (E2), and cortisol (F) were measured in peripheral and right adrenal venous blood of an amenorrheic patient with a right virilizing adrenal adenoma. Urinary 17-ketosteroids were markedly elevated and were not suppressed on a low dose of dexamethasone (Dex) for 7 days. Peripheral T level was 1.2 ng/ml and DHEA-S was 13,500 ng/ml. Calculations of the ratios of adrenal venous gradients for delta5 and delta4 steroids suggest that the predominant pathway of steroid secretion used by the tumor was as follows: pregnenolone (delta5P) leads to 17delta5P leads to DHEA leads to A leads to T. Following removal of the adenoma, T returned to normal levels but DHEA-S was still above normal at 4100 ng/ml. The patient became eumenorrheic with marked improvement at her hirsutism and virilization.
