The cardiometabolic implications of Non-Functioning Adrenal Incidentaloma (NFAI) is still matter of debate. This study takes a novel approach to analyze this association, accounting for the influence of various confounding factors. We present the findings of a retrospective, cross-sectional, and case-control study. Data from all NFAI patients in primary prevention, referred to the University of Turin between 2000 and 2023, were collected and compared with subjects without adrenal disease, using propensity score matching analysis. A total of 1997 patients were included (906 patients with NFAI; 1091 controls). Adrenal tumor group was associated with high levels of cardiovascular risk scores in both univariate and multiple linear regression analyses (Progetto CUORE: EC 11.00, 95% CI 2.72-44.46, p = 0.001; SCORE: EC 1.97, 95% CI 1.01-3.81, p = 0.046). Regarding cardiometabolic complications, multivariable logistic regression revealed an independent association between NFAI and ascending aorta dilation (OR 4.64, 95% CI 2.24-9.63, p = 0.000), after adjusting for age, sex, smoking status, metabolic syndrome, number of antihypertensive drugs, estimated glomerular filtration rate (eGFR), and normetanephrine levels. Propensity score matching analysis (1:1 matching ratio), based on the same logistic regression model, confirmed the association of NFAI with aortic dilation (β = 0.083, 95% CI 0.008-0.157, p = 0.030). No significant associations were found with metabolic syndrome, type II diabetes, eGFR <60 mL/min/1.73 m2, microalbuminuria, atrial fibrillation, or hypertensive heart disease. This study suggests that patients with NFAI face increased cardiometabolic risk and high prevalence of ascending aorta dilation. Routine evaluation of NFAI patients should include thorough cardiovascular assessment and consideration of treatments aimed at reducing cardiovascular risk.

The transformation of an adrenocortical adenoma (ACA) to an adrenocortical carcinoma (ACC) is extremely rare. Current guidelines suggest against further imaging studies and follow-up in patients with nonfunctional adrenal incidentalomas (NFAIs) with benign imaging characteristics. Herein, we present a 64-year-old male patient diagnosed initially with a NFAI of 3 cm in size with imaging characteristics consistent with an ACA. However, 13 years after initial diagnosis, this apparent ACA developed into a high-grade cortisol and androgen-secreting ACC with synchronous metastases. The literature review revealed a further 9 case reports of adrenal incidentalomas initially characterized as ACA that subsequently developed into ACC within a period ranging from 1 to 10 years. The pathogenesis of transformation of an initially denoted ACA to ACC is not fully delineated, although the existing literature focuses on the preexisting or changing genetic background of these lesions, highlighting the need to develop robust prognostic markers to identify patients at risk and individualize the follow-up of these unique cases.

OBJECTIVE: The aim was to explore the preoperative and postoperative fibrinogen changes value (FCV) as a prognosis biomarker for in patients with adrenocortical carcinoma (ACC).
METHODS: We identified 42 patients with ACC and 190 patients with adrenal adenoma (AA) who underwent surgery at our institution between 2015 and 2023. Preoperative fibrinogen, postoperative fibrinogen and follow-up information of the patients were recorded and analysed. The relationship between FCV and overall survival (OS)/ relapse-free survival (RFS) was evaluated.
RESULTS: The mean level of preoperative and postoperative fibrinogen for ACC were 4.00 ± 1.64 g/L and 2.75 ± 0.59 g/L, respectively (p < 0.001). The mean level of preoperative and postoperative fibrinogen for AA were 2.79 ± 0.59 g/L and 2.71 ± 0.58 g/L, respectively (p = 0.144). In ACC, the lower FCV (≤ 1.25 g/L) showed a significantly poorer RFS than the higher (> 1.25 g/L) (p = 0.007); however, the lower FCV (≤ 1.25 g/L) showed no poorer OS than the higher (> 1.25 g/L) (p = 0.243). On multivariate survival analyses, FCV remained a predictor of RFS (HR 3.138).
CONCLUSIONS: According to the data in this study, it can be said that FCV is correlated with prognosis of ACC. The FCV might be a new biomarker for predicting the RFS of ACC.

This case report describes the surgical management of a giant left adrenal mass (27 x 26 × 27 cm, 9.370 kg) in a 69-year-old female. We review the multidisciplinary decision-making process for pre-operative preparation, embolization, resection feasibility, and strategies to mitigate intra-operative complications. This is the largest adrenal adenoma removal reported to date. The case highlights the importance of meticulous surgical planning and execution in managing rare and challenging cases, with significant implications for patient outcomes.

BACKGROUND: Functioning adrenal adenoma during pregnancy is rare, and the diagnosis is challenging owing to unspecific symptoms and restricted investigations. The obstetric outcomes of patients who undergo surgery during pregnancy or who receive only medical treatment are poorly described.
OBJECTIVE: The aim was to investigate the associations between functioning adrenal adenomas and obstetric outcomes.
METHODS: A retrospective study was performed in a tertiary center over 20 years. The clinical characteristics, management and obstetric outcomes of the diagnosed pregnant women were reviewed.
RESULTS: A total of 12 women were diagnosed with functioning adrenal adenomas during pregnancy from January 2002 to September 2022. Eight women had cortisol-secreting adrenal adenomas, two had excessive catecholamine secretion, and two had primary aldosteronism. The initial symptoms of adrenal adenoma during pregnancy included hypertension or preeclampsia, gestational diabetes mellitus or prepregnancy diabetes mellitus, hypokalemia and ecchymosis. Four women underwent adrenalectomy during pregnancy, while 8 women received only medical therapy. Preterm birth occurred in all patients who received medicine, whereas 1 patient who underwent surgery experienced preterm birth. Among the 8 women in the medical treatment group, 3 had neonates who died.
CONCLUSIONS: Once hypertension, hyperglycemia and hypokalemia occur during the 1st or 2nd trimester, pregnant women with adrenal adenomas should be evaluated via laboratory and imaging examinations. The maternal and fetal outcomes were unpredictable owing to the severity of adrenal adenoma, particularly in patients who received only medical treatment. Adrenalectomy should be recommended during pregnancy.

BACKGROUND: There is a lack of solid long-term evidence with respect to the management over time of adrenal incidentalomas that miss clearly benign radiological features. We present the case of a 75-year-old man with a non-secreting adrenal mass, apparently stable in size (14 mm) and unchanged in features for 2 years, but subsequently diagnosed as adrenal carcinoma.
METHODS: The patient was referred to Grande Ospedale Metropolitano Niguarda in August 2022 due to the presence of a large lesion in the left adrenal site. In 2017, a 14 mm, 20 HU, round, regular-edged lesion was detected at a CT scan without contrast medium. Over the next two years, the patient was re-evaluated every 6 months with follow-up CT scans with no apparent densitometric or dimensional changes in the known lesion. In September 2022, 3 years after the last CT scan, the patient was hospitalised for pneumonia. An abdominal CT scan acquired during the hospitalisation showed an increase of the lesion to 14.5x10x12 cm. The patient subsequently underwent open nephrosurrenectomy, and histological examination confirmed the presence of an adrenal carcinoma (proliferation index 5%, Weiss score 7). No adjuvant therapy was administered, and the last CT scan in December 2022 was negative for the recurrence of the disease.
CONCLUSIONS: Adrenal carcinoma usually presents as a clearly malignant lesion with rapid growth and a marked tendency to metastasise. This case highlights how an adrenal adenoma with indeterminate features is worthy of follow-up over time despite its apparent dimensional and radiological stability [1].

BACKGROUND: Somatic mutations have been observed to induce aldosterone-producing adenomas (APAs). These may be accelerated during pregnancy. Somatic PRKACA mutations are common in cortisol-producing adenomas (CPAs). However, their role in APAs, particularly aldosterone- and cortisol-producing adenomas (A/CPAs), is not well understood. This study aims to investigate the association between PRKACA mutations and the accelerated development of A/CPAs during pregnancy.
METHODS: A patient with primary aldosteronism (PA) associated with severe Cushing\'s syndrome (CS) underwent surgical resection of an adrenal tumor one year after delivery. Pathologic examination revealed an adrenocortical adenoma characterized primarily by zona glomerulosa hyperplasia. Somatic mutation analysis revealed the presence of the somatic PRKACA mutation, which was validated as a deleterious mutation by various computational databases. Immunohistochemical results showed positive staining for cytochrome P450 family 11 subfamily B member 1 (CYP11B1), cytochrome P450 family 11 subfamily B member 2 (CYP11B2), and luteinizing hormone/chorionic gonadotropin receptor (LHCGR). Our study included a review of 20 previously documented cases of aldosterone- and cortisol-producing adenomas (A/CPAs), two of which were concurrently positive for both CYP11B1 and CYP11B2, consistent with our findings.
CONCLUSIONS: Somatic mutations in PRKACA may correlate with the upregulation of LHCGR, which synergistically drives the accelerated growth of co-secretion tumors during pregnancy, thereby exacerbating disease progression.

BACKGROUND: Mild autonomous cortisol secretion (MACS) is diagnosed based on post-dexamethasone cortisol>1.8 mcg/dL. Scarce evidence exists on steroid circadian secretion and steroid metabolome in MACS.
OBJECTIVE: To characterize 24-hour (h) urine steroid metabolome in patients with MACS and determine circadian differences in urine steroid profiling and cortisol concentrations in patients with MACS versus referent subjects.
METHODS: Cross-sectional study, 2018-2023.
METHODS: Referral center.
METHODS: Patients with MACS and age-, sex-, BMI-, and menopausal status-matched referent subjects.
METHODS: Urine was collected over 24h period as separate day- and night-time collections. High-resolution mass spectrometry assay was used to measure 25 steroids. A subgroup of patients and referent subjects were admitted for every 2h serum measurements of free and total cortisol.
RESULTS: Steroids, sums, and ratios.
RESULTS: Patients with MACS (n=72) had lower mcg/24h median androgens (2084 vs 3283, P<0.001), higher glucocorticoids (15754 vs 12936, P<0.001), and higher glucocorticoid/androgen ratio (8.7 vs 3.9, P<0.001), compared to referent subjects. Patients also had lower steroid day/night ratios compared to referent subjects, reflecting a higher relative nocturnal steroid production in MACS. In a subgroup of 12 patients with MACS and 10 referent subjects, the 24-hour area under the curves for total and free cortisol were similar. However, evening mean total (5.3 vs 4.0 mcg/dL, P=0.056) and free (0.2 vs 0.1 mcg/dL, P=0.035) cortisol was higher in patients vs referent subjects.
CONCLUSIONS: Patients with MACS demonstrate an abnormal urine steroid metabolome, with a high glucocorticoid to androgen ratio, and a higher nocturnal steroid production.

Most adrenal incidentalomas are benign neoplasms of the adrenal cortex. While the majority are nonfunctional, many secrete cortisol. Androgen- or estrogen-secreting adenomas are rare. A 44-year-old female, with history of hypertension and prediabetes, presented with worsening acne, hirsutism, secondary amenorrhea for 2 years, and a 40-pound weight gain. Laboratory evaluation showed high 24-hour urine free cortisol, suppressed adrenocorticotropic hormone (ACTH) level, indicative of ACTH independent Cushing syndrome, and elevated testosterone and androstenedione. Abdominal computed tomography (CT) revealed a 6.3 × 5.2 × 5.6 cm left adrenal mass. Patient underwent left open adrenalectomy. Pathology revealed benign adrenocortical adenoma. Postoperatively there was a significant improvement in her blood pressure and blood sugar levels, resumption of menses, and complete resolution of hyperandrogenism and hypercortisolism. We describe a patient with an adrenal adenoma cosecreting cortisol and androgen, leading to Cushing syndrome and significant virilization. Adrenal masses secreting androgens are less common and concerning for adrenocortical carcinoma (ACC). Patients with adrenal masses cosecreting multiple hormones should undergo workup expediently since ACC confers poor outcomes.
