Adrenocorticotropic hormone (ACTH)-producing pheochromocytoma requires precise localization for effective treatment. Adrenal vein sampling (AVS) offers a viable alternative to nuclear scintigraphy for lateralizing these rare adrenal tumors.
Area of Science:
- Endocrinology
- Oncology
- Diagnostic Imaging
Background:
- Adrenocorticotropic hormone (ACTH)-producing pheochromocytoma presents with complex hormonal imbalances.
- Accurate tumor localization is essential for surgical planning, aiming for unilateral adrenalectomy to preserve adrenal function.
Observation:
- Nuclear scintigraphy, the traditional gold standard for localization, faces challenges due to radiotracer shortages.
- Adrenal vein sampling (AVS) was employed as an alternative diagnostic method.
Findings:
- Adrenal vein sampling successfully lateralized the adrenal pheochromocytoma in this case.
- The technical approach and interpretation nuances for ACTH-producing pheochromocytoma differ from standard AVS procedures for other adrenal conditions.
Implications:
- Adrenal vein sampling provides a crucial alternative for localizing ectopic ACTH sources when scintigraphy is unavailable.
- This case highlights the adaptability of AVS in diagnosing rare endocrine disorders and informs future diagnostic strategies.

01:27Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
01:31Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
