Cortisol is the major glucocorticoid hormone synthesized by the adrenal cortex in response to adrenocorticotropic hormone ACTH which is secreted by the pituitary gland. Cortisol is involved in a negative feedback loop with hypothalamic and pituitary hormones synthesis and secretion. Production of cortisol is dependant of the hypothalamopituitary-adrenal cortex axis HPA functioning, and of the presence of enzymes responsible of different synthesis pathways of steroids hormones.

Hypertension is a frequent complication of pregnancy and may compromise fetal and maternal outcome. Hypertension may be pregnancy-induced, essential or secondary to endocrine disorders. Most cases of endocrine hypertension are the consequence of adrenal diseases. Pheochromocytoma, hypercorticism, primary aldosteronism or glucocorticoid-remediable aldosteronism can be present or diagnosed at any term and may cause severe hypertension. Clinical clues and biological tests are similar to those used in non-pregnant subjects. Tests for tumor location are limited to ultrasound and magnetic resonance scans in order to avoid maternal and fetal irradiation.
