DISEASES OF THE ADRENAL GLANDS - CLINICAL FINDINGS
Pancreatic Disease Symptoms Signs Abnormal Lab Test Results Abnormal Imaging Findings Initial Treatment General and Follow-Up Treatment Age Range(s) Typically Found Prognosis
Cushing's Syndrome Weight gain, moon face, buffalo hump, hypertension, muscle weakness Central obesity, purple striae, hirsutism, easy bruising ↑Cortisol, ↑ACTH (if ACTH-dependent), failed dexamethasone suppression test Adrenal hyperplasia or tumor on CT/MRI, pituitary tumor if Cushing’s disease Surgical removal if tumor; ketoconazole, metyrapone if not surgical Monitor cortisol levels post-treatment, manage osteoporosis and diabetes Adults 20-50 years, more common in women Good with treatment, high morbidity if untreated
Addison's Disease Fatigue, weight loss, salt craving, nausea, hypotension Hyperpigmentation, orthostatic hypotension, loss of body hair ↓Cortisol, ↑ACTH, hyponatremia, hyperkalemia, ↓Aldosterone Small adrenal glands on CT/MRI, sometimes calcifications Glucocorticoid and mineralocorticoid replacement (hydrocortisone, fludrocortisone) Lifelong hormone replacement, monitor for crisis triggers Any age, most common in middle-aged adults Good with lifelong hormone replacement, fatal if untreated
Primary Aldosteronism Hypertension, muscle cramps, polyuria, headache Resistant hypertension, hypokalemia, metabolic alkalosis ↑Aldosterone, ↓Renin, hypokalemia, metabolic alkalosis Unilateral adrenal adenoma or bilateral hyperplasia on imaging Spironolactone or eplerenone; surgical removal if unilateral Blood pressure and potassium monitoring, long-term medication if needed Middle-aged to older adults, more common in women Good if treated, increased cardiovascular risk if uncontrolled
Pheochromocytoma Episodic headaches, palpitations, sweating, hypertension Tachycardia, sweating, pallor, severe hypertension ↑Metanephrines, ↑Catecholamines in plasma and urine Adrenal mass with high contrast washout on CT, MRI hyperintensity Surgical removal of tumor; alpha-blockade (phenoxybenzamine) pre-op Regular biochemical testing for recurrence, genetic screening for syndromes Adults 30-60 years, rare in children Good with complete removal, risk of recurrence if genetic
Adrenal Incidentaloma Often asymptomatic, may have mild hormone excess symptoms May show mild hypercortisolism, hyperaldosteronism, or be non-functional Variable; possible mild ↑Cortisol, ↑Aldosterone, or catecholamines Incidental adrenal mass, >4 cm may suggest malignancy Observation for small, non-functional lesions; surgery if >4 cm or hormonal Repeat imaging and hormonal testing if needed Any age, more common in older adults Generally good; malignancy risk increases with size
Congenital Adrenal Hyperplasia (CAH) Ambiguous genitalia in newborns, precocious puberty, salt-wasting crisis Hyperpigmentation, virilization in females, hypertension ↑17-OH progesterone, ↓Cortisol, ↓Aldosterone, ↑Androgens Bilateral adrenal hyperplasia on imaging Hydrocortisone, fludrocortisone for salt-wasting type Lifelong glucocorticoid and mineralocorticoid replacement if necessary Newborns and infants, detected via screening Good with treatment; can cause serious complications if untreated
Adrenocortical Carcinoma Abdominal pain, weight loss, hormonal symptoms depending on secretion Abdominal mass, Cushingoid features, virilization or feminization ↑Cortisol, ↑DHEA, variable aldosterone and androgen levels Large adrenal mass, irregular margins, invasion of surrounding structures Surgical removal if localized; chemotherapy if metastatic Oncologic follow-up, high recurrence risk if metastatic Middle-aged to older adults, rare but aggressive Poor prognosis if metastatic; localized cases may be curable
Adrenal Hemorrhage Acute flank pain, hypotension, fever, shock in severe cases Flank tenderness, signs of adrenal insufficiency if bilateral ↓Cortisol if severe, anemia, thrombocytopenia Adrenal enlargement or hemorrhagic changes on CT/MRI Supportive care, treat underlying cause, adrenalectomy if needed Monitor adrenal function, replace hormones if necessary Any age, commonly in critically ill patients Variable; mild cases recover, severe cases can be fatal
