Abstract

An adrenal incidentaloma is now established as a common endocrine diagnosis that requires a multidisciplinary approach for effective management. The majority of patients can be reassured and discharged, but a personalized approach based upon image analysis, endocrine workup, and clinical symptoms and signs are required in every case. Adrenocortical carcinoma remains a real concern but is restricted to <2% of all cases. Functional adrenal incidentaloma lesions are commoner (but still probably <10% of total) and the greatest challenge remains the diagnosis and optimum management of autonomous cortisol secretion. Modern-day surgery has improved outcomes and novel radiological and urinary biomarkers will improve early detection and patient stratification in future years to come.

TL;DR

Adrenal incidentaloma is a common endocrine diagnosis requiring multidisciplinary, personalized assessment; most patients can be reassured and discharged once malignancy and hormone hypersecretion are excluded. Adrenocortical carcinoma remains a concern but is <2% of cases, while functional lesions are commoner and autonomous cortisol secretion is the greatest diagnostic and management challenge.

Key findings

  • AI affects ~2% of the general population and over 7% of those over 70 years; it is rare below 40 years. About 2% of patients with AI have adrenocortical cancer, and up to 10% have autonomous secretion of adrenal hormones.
  • The initial investigation of choice is an unenhanced CT of both adrenal glands. An unenhanced CT attenuation of ≤10 HU is consistent with a lipid-rich benign adenoma; pheochromocytomas have mean HU scores of 30 to 35, and only 0.5% have an unenhanced CT attenuation of ≤10 HU.
  • Pheochromocytoma and autonomous cortisol secretion should be excluded in every case, and aldosteronism in patients with underlying hypertension and/or hypokalemia. For ACS screening, a post-dexamethasone cortisol ≤1.8 µg/dL is normal, 1.9–5.0 µg/dL may indicate possible ACS, and >5.0 µg/dL suggests ACS; sensitivity rises from 80% at a 140 nmol/L cutoff to 95% at 50 nmol/L, with lower specificity.
  • Most patients with AI can be discharged once malignancy and hormone hypersecretion have been excluded. A causative link between cortisol hypersecretion and age-related comorbidities should be firmly established before recommending surgical excision.

Methods

  • Narrative review synthesizing epidemiology, anatomy and physiology, etiology, endocrine workup, imaging, surgical management, and future biomarkers for adrenal incidentaloma.
  • Data are drawn from published autopsy, CT, clinical series, guidelines, systematic reviews, and meta-analyses; no primary patient cohort or new experimental data are presented.
  • Main analysis is qualitative synthesis and tabulation of published literature, including tables of prevalence, diagnostic tests, and surgical outcomes; no formal systematic review or meta-analysis methods are stated.

Limitations

  • The paper states that many included studies are limited by retrospective nature, specialized center bias, patient selection bias, recall bias, and small sample size; source data are highly variable in autopsy, surgery, or radiological origin, patient selection, and AI definition.
  • The paper states there is no gold standard test for diagnosing ACS, false positives are common, and age-related comorbidities can themselves cause physiological hypercortisolism; robust evidence for surgical treatment of ACS is lacking, with most studies small, retrospective, uncontrolled, and nonrandomized.
  • Evident from the text: as a narrative review, it does not describe a systematic search strategy or formal quality assessment, so recommendations rest on heterogeneous observational data and expert synthesis.

    The higher prevalence in Song et al. may be because the study protocol included a dedicated radiological review of adrenal imaging in a significant percentage of cases, possibly resulting in diagnosis of more AI than in routine practice.

  • Herrera CT frequency does not match the counts

  • Yener unilateral and bilateral counts exceed the patient total

    Minor

    Five of nine patients is about 55.6%; 44% would correspond approximately to four of nine.

  • Early CT prevalence range omits the table's 0.3% result

    Minor

    The text says CT series published between 1982 and 1986 reported prevalences from 0.6% to 1.3%, but Table 2 includes a 1982 series reporting 0.3%.

  • Overall functional-lesion estimates conflict

    Minor

    The conclusion estimates that functional lesions account for probably less than 10% of adrenal incidentalomas, while the clinical-presentation section states that 10% to 15% secrete hormones in excess.

  • Stated autopsy prevalence range excludes a listed large study

    Minor

    The text gives 1.05% as the lower end of the range for autopsy series with more than 1,000 patients. Table 1 lists a 321,847-patient study with a prevalence of 0.03%.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
