Adrenal cysts: hormonal contents and functional evaluation.

J D Jacobi, A Carballeira, L M Fishman

    Acta Endocrinologica
    |June 1, 1978
    PubMed
    Summary

    Hormones like cortisol and epinephrine were found in adrenal cysts from patients without endocrine issues. These hormones likely diffuse from the adrenal gland, meaning cyst presence doesn't affect endocrine function.

    Area of Science:

    • Endocrinology
    • Adrenal Gland Physiology
    • Biochemistry

    Background:

    • Adrenal cysts are uncommon findings.
    • Their hormonal content and origin remain largely uncharacterized.
    • Patients with adrenal cysts often lack endocrine dysfunction.

    Purpose of the Study:

    • To identify and quantify hormones in adrenal cysts.
    • To investigate the origin of these hormones.
    • To determine if adrenal cysts impact endocrine function.

    Main Methods:

    • Analysis of adrenal cysts (capsule and fluid) from two patients.
    • Measurement of cortisol, corticosterone, epinephrine, and norepinephrine.
    • Assessment of cholesterol content and utilization for steroidogenesis using [4-14C] cholesterol.

    Main Results:

    • Cortisol, corticosterone, epinephrine, and norepinephrine were detected in adrenal cysts.
    • Hormone concentrations in cysts were higher than plasma but lower than adrenal tissue.
    • Cysts contained preformed cholesterol but could not synthesize steroids from it.

    Conclusions:

    • Hormones in adrenal cysts likely originate from passive diffusion from the adjacent adrenal gland.
    • Adrenal cysts themselves do not appear to be hormonally active.
    • Patient endocrine status is determined by the non-cystic adrenal tissue.
