Update on the risks of benign adrenocortical incidentalomas
1Endocrinology Unit - Department of Medical and Surgical Sciences, Alma Mater Studiorum University of Bologna, S. Orsola-Malpighi Hospital, Bologna, Italy.
Nonfunctioning adrenal incidentalomas (NFAIs) increase diabetes risk, while autonomous cortisol secretion (ACS) or NFAIs progressing to ACS heighten cardiovascular disease risks. Early detection and management are crucial.
Area of Science:
- Endocrinology
- Oncology
- Metabolic Diseases
Background:
- Adrenocortical incidentalomas are increasingly recognized for their association with comorbidities.
- Understanding the risks of nonfunctioning adrenal incidentalomas (NFAIs) and those with autonomous cortisol secretion (ACS) is critical.
Purpose of the Study:
- To review recent evidence on the risks associated with NFAIs and ACS.
- To summarize potential comorbidities linked to these adrenal tumors.
Main Methods:
- Literature review of recent studies on adrenocortical tumors.
- Synthesis of evidence regarding metabolic and cardiovascular risks.
Main Results:
- Autonomous cortisol secretion (ACS) is linked to glucose metabolism alterations in 30% of cases, with surgery potentially improving diabetes.
- Nonfunctioning adrenal incidentalomas (NFAIs) are associated with insulin resistance and an increased risk of developing prediabetes/diabetes.
- Both ACS and NFAIs carry increased risks for cardiovascular events and mortality, with 13% of NFAIs potentially progressing to ACS.
Conclusions:
- NFAIs pose a risk for developing glucose metabolism disturbances.
- ACS and NFAIs that convert to ACS increase the likelihood of cardiovascular diseases.

Adrenal 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...
Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct...
Hormones 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...
Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
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...
