Abstract
Adrenal incidentalomas have increased due to advanced and more sensitive imaging modalities, their increased utilization, and the aging population. Most adrenal incidentalomas are nonfunctional and benign, but a subset of patients has functional and/or malignant tumors. The evaluation of patients with an adrenal incidentaloma involves addressing 2 clinical questions: (1) Is the tumor functional? (2) Is the tumor malignant? A careful history and physical examination focused on signs and symptoms of adrenal functional tumors, biochemical testing, and imaging features are the cornerstone in the evaluation of patients with an adrenal incidentaloma.

Abstract
Bilateral adrenal masses, increasingly encountered in clinical practice, manifest across diverse contexts, including incidental discovery, malignancy staging, and targeted imaging after hormonal diagnosis of adrenal disorders. The spectrum encompasses various pathologies, such as cortical adenomas, macronodular adrenal disease, pheochromocytomas, myelolipomas, infiltrative disorders, and primary and secondary malignancies. Notably, not all masses in both adrenal glands necessarily share the same etiology, often exhibiting diverse causes. Recently, the European Society of Endocrinology and the European Network for the Study of Adrenal Tumors updated guidelines, introduced a 4-option schema based on imaging, aiding in targeted hormonal testing and management. This "Approach to the Patient" review delves into the latest advancements in imaging, biochemical, and genetic approaches for the diagnostic and management nuances of bilateral adrenal masses. It provides insights and a contemporary framework for navigating the complexities associated with this clinical entity.

Abstract
PURPOSE Data guiding management of pheochromocytoma and paraganglioma (PPGL) in pregnant women is limited, and long-term effects on the child are unknown. The aim of this retrospective registry-based case-cohort study was to assess how maternal PPGL and treatment impacts maternal and fetal outcome, including long-term outcome for the child. The main outcomes were maternal and fetal mortality and morbidity at delivery and relative healthcare consumption in children born by mothers with PPGL during pregnancy. METHODS The National Birth Register identified 4,390,869 pregnancies between 1973-2015. Data was crosslinked with three Swedish national registers to identify women diagnosed with pheochromocytoma or paraganglioma within one year before or after childbirth. Hospital records were reviewed and register data was collected for five age-matched controls for each child until age 18. RESULTS 21 women and 23 children were identified (incidence 4.8/1.000.000 births/year), all women with adrenal pheochromocytomas (Pc). The majority (71%) were diagnosed post-partum. Nine women (43%) were hypertensive during pregnancy. Preterm delivery was more common in Pc patients compared to controls (30% vs 6%, p < 0.001). There was no maternal or fetal mortality. Timing of tumor removal did not affect gestational weight or APGAR scores. There was no observed difference in hospital admissions between children affected by maternal Pc and controls. CONCLUSION Pc was commonly diagnosed after delivery and raised the risk of pre-term delivery, suggesting a need for an increased awareness of this diagnosis. However, reassuringly, there was no fetal or maternal mortality or any observed long-term impact on the children.

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.

Abstract
Focal lesions of the adrenal glands are incidentally detected in approximately 5% of cases by modern imaging techniques. Fewer than 5% of these adrenal incidentalomas are malignant and approximately 10% have endocrine activity. Reliable differentiation of malignant versus benign and hormonally active versus nonfunctional adrenal incidentalomas significantly influences therapeutic management and the outcome of affected individuals. Therefore, each adrenal incidentaloma should undergo a standardized diagnostic work-up to exclude malignancy and endocrine activity. This position statement of the World Federation of Ultrasound in Medicine and Biology (WFUMB) summarizes the available evidence on the management of adrenal incidentaloma and describes efficient management strategies with particular reference to the role of ultrasound techniques.

Abstract
OBJECTIVE To evaluate whether the 2016 European Society of Endocrinology (ESE) recommendations for the management of adrenal incidentalomas accurately classifies those patients who do not require further follow-up. DESIGN AND METHODS Single centre retrospective study. From 2010 to 2015, 130 patients with adrenal incidentaloma were evaluated and followed-up. Clinical, analytical and radiological data were recorded and the presence of comorbidities was assessed. Patients were grouped as nonfunctional or subclinical Cushing syndrome according to American guidelines; and nonfunctional, possible autonomous cortisol secretion and autonomous cortisol secretion, according to ESE guidelines. RESULTS Based on American guidelines, 94% of patients had nonfunctional adrenal incidentalomas and 6% had subclinical Cushing syndrome. Based on ESE guidelines, patients were classified into nonfunctional (54%), possible autonomous cortisol secretion (40%) and autonomous cortisol secretion (6%) groups. No differences were observed in demographic characteristics and comorbidities between groups in either classification. Following ESE guidelines, no patient in the nonfunctional group was reclassified into the possible autonomous or autonomous cortisol secretion groups during follow-up, but one patient in the possible autonomous cortisol secretion group was reclassified into the autonomous cortisol secretion group. Also, 30 patients included in the groups of possible autonomous or autonomous cortisol secretion experienced progression of a comorbidity associated with cortisol excess, with diabetes mellitus as the most frequent comorbidity observed. CONCLUSION Although adrenal incidentalomas with an excess of cortisol secretion were more frequently diagnosed with the new ESE recommendations, patients who did not require longer follow-up after first evaluation were accurately classified.

Abstract
Bilateral adrenal abnormalities are not infrequently encountered during routine daily radiology practice. The differential diagnoses of bilateral adrenal abnormalities include neoplastic and non-neoplastic entities. The bilateral adrenal tumors include metastasis, lymphoma, neuroblastoma, pheochromocytoma, adenoma, and myelolipoma. Non-neoplastic bilateral adrenal masses include infectious processes and haematomas. There are different diffuse bilateral adrenal changes such as adrenal atrophy, adrenal enlargement, adrenal calcifications, and altered adrenal enhancement. In this pictorial review article, we will discuss the imaging features of these entities with emphasis on their clinical implications.

Abstract
BACKGROUND The majority of adrenal incidentalomas are benign, although some are large, functional, or malignant and may require surgery. Therefore all require follow-up. This study aimed to determine the pattern of adrenal incidentaloma follow-up in a level 1 trauma center, focusing on the factors that influence whether follow-up is facilitated. METHODS Patients with computed tomography-detected adrenal incidentalomas between January 2010 and September 2015 were included. A keyword search identified case files, which were reviewed for demographic characteristics, managing unit, computed tomography indication and findings, and follow-up arrangements. Statistical analysis was performed using Stata SE Version 14. RESULTS A total of 38,848 chest and abdominal computed tomographic scans were performed in the study period, revealing 804 patients with adrenal incidentalomas who met inclusion criteria (mean age 65, 58% male). The mean size of adrenal incidentaloma was 23 mm. Follow-up was organized in 30% of cases and was more likely to occur in younger patients (mean age 62 vs 66, P < .001); in larger lesions (mean size 26 mm vs 21 mm, P < .001); if the computed tomographic scan suggested follow-up (P < .001); or if the computed tomography report suggested a diagnosis (P < .001). Follow-up arrangements were most likely to be made by the trauma unit (39%, P = .01). CONCLUSION This study highlights that adrenal incidentalomas follow-up is often overlooked, and that follow-up is influenced by patient, radiologic, and medical provider factors. An adrenal lesion follow-up protocol may improve follow-up rates but requires further analysis.

Abstract
BACKGROUND Adrenal masses are a known extraintestinal manifestation of familial adenomatous polyposis. However, the literature on this association is largely confined to case reports. OBJECTIVE This study aimed to determine the characteristics of adrenal masses in familial adenomatous polyposis and their clinical significance, as well as to estimate their prevalence. Mutational analysis was conducted to determine if any potential genotype-phenotype correlations exist. DESIGN This is a retrospective cohort study. SETTING Analysis included all patients meeting the criteria of classic familial adenomatous polyposis who were registered with the Familial Gastrointestinal Cancer Registry, a national Canadian database. PATIENTS Appropriate imaging or autopsy reports were available in 311 registry patients. Patients with adrenal metastases were excluded. OUTCOME MEASURES Data collection included demographic data, mutation genotype, adrenal mass characteristics, surgical interventions and mortality. RESULTS The prevalence of adrenal masses was 16% (n = 48/311). The median age at diagnosis of adrenal mass was 45 years. The median diameter of adrenal mass at diagnosis was 1.7 cm (interquartile range, 1.4-3.0) with a median maximal diameter of 2.5 cm (interquartile range, 1.7-4.1) with median imaging follow-up of 48 months. The majority of adrenal masses were benign (97%, n = 61/63). Surgery was performed on 7 patients because of concerns for size, malignancy, or hormonal secretion. One adrenal-related death was due to an adrenocortical carcinoma. Mutation analysis did not identify any specific genotype-phenotype correlations. LIMITATIONS There were incomplete or insufficient endocrinology data available in the registry to allow for the analysis of hormone secretion patterns. CONCLUSIONS Adrenal masses are approximately twice as prevalent in the familial adenomatous polyposis population as in previous studies of the general population. Nearly all mutations led to truncation of the APC gene; however, there was no genetic signature to help predict those at increased risk. The majority of adrenal lesions identified were of benign etiology; thus, an intensive management or surveillance strategy with imaging screening is likely unwarranted.

Abstract
OBJECTIVE The purpose of this study was to determine the rate of malignancy in incidentally detected bilateral adrenal masses in patients with no known history of cancer. MATERIALS AND METHODS A retrospective search of CT reports of patients with incidentally detected bilateral adrenal nodules was performed from January 1, 2002, to January 1, 2014. Patients were excluded if they had a known cancer or suspected functioning adrenal tumor; 161 patients were included. Nodules were characterized as benign or malignant on the basis of imaging features at the index CT examination, imaging features at subsequent adrenal protocol CT or MRI, imaging stability for a minimum of 1 year, or clinical follow-up of a minimum of 2 years. RESULTS Mean nodule size was 1.8 cm (range, 0.7-4.9 cm). There were no cases of primary or secondary adrenal malignancy (95% CI, 0.00-0.023). The nodules diagnosed on index CT scans were 73 adrenal adenomas and two myelolipomas. Seventy-four nodules were subsequently characterized as adrenal adenomas on the basis of imaging findings. Of the 113 indeterminate nodules that had imaging follow-up, 111 were stable at the latest follow-up examination. One nodule grew 26% over 8.1 years, and the other grew 59% over 12.4 years. Clinical follow-up of patients with 60 indeterminate nodules revealed no evidence of adrenal malignancy. CONCLUSION No case of malignancy was found in 322 incidentally detected bilateral adrenal nodules at CT of patients without known cancer. Imaging follow-up of such lesions may be unnecessary.

Abstract
OBJECTIVE Recently, the European Society of Endocrinology (ESE), in collaboration with the European Network for the Study of Adrenal Tumors (ENSAT), asserted that adrenal incidentalomas (AIs) <4 cm and ≤10 Hounsfield units (HU) do not require further follow-up imaging. To validate the clinical application of the follow-up strategies suggested by the 2016 ESE-ENSAT guidelines, we explored the clinical characteristics and natural course of AIs in a single center over 13 years. DESIGN AND METHODS This retrospective cohort study included a total of 1149 patients diagnosed with AIs between 2000 and 2013 in a single tertiary center. Hormonal examination and radiological evaluations were performed at the initial diagnosis of AI and during the follow-up according to the appropriate guidelines. RESULTS The mean age at diagnosis was 54.2 years, and the majority of AIs (68.0%) were nonfunctional lesions. Receiver operating curve analysis was used to discriminate malignant from benign lesions; the optimal cut-off value for mass size was 3.4 cm (sensitivity: 100%; specificity: 95.0%), and that for the pre-contrast HU was 19.9 (sensitivity: 100%; specificity: 67.4%). The majority of nonfunctional lesions did not change in size during the 4-year follow-up period. Applying a cut-off value of 1.8 μg/dL after a 1-mg overnight dexamethasone suppression test, 28.0% of all nonfunctional AIs progressed to autonomous cortisol secretion during the follow-up period. However, we observed no development of overt Cushing's syndrome in the study. CONCLUSIONS We advocate that no follow-up imaging is required if the detected adrenal mass is <4 cm and has clear benign features. However, prospective studies with longer follow-up are needed to confirm the appropriate follow-up strategies.

Abstract
Recently, the European Society of Endocrinology (ESE) published new guidelines on the management of adrenal incidentalomas. At the same time Lopez and coworkers published on the Annals of Internal Medicine an important study showing that even patients with non-functioning adrenal tumors have an increased risk of incident diabetes. In consideration of previous data and of the results of the study of Lopez and coworkers, some points emerge from the ESE Guidelines that deserve attention. Firstly, it must be observed that the term "autonomous cortisol secretion," introduced by the ESE Panel in the place of the commonly used "subclinical hypercortisolism," seems questionable, since the guidelines do not suggest determining the adrenocorticotroph hormone levels that could give the certain proof of a truly autonomous cortisol secretion. Secondly, the ESE Guidelines suggest against repeated hormonal workup in AI patients with a normal hormonal secretion at initial evaluation, but also in those with a "possible autonomous cortisol secretion," if in the absence of comorbidities potentially related to hypercortisolism. Thirdly, the ESE Guidelines suggest against further imaging during follow-up in patients with an adrenal mass below 4 cm in size with clear benign features on imaging studies. Considering the available literature data that are briefly summarized in this comment, we believe that no sufficient evidence is available to date for giving sharp-cutting recommendations about the uselessness of a biochemical and morphological follow-up in AI patients, even in those with initially benign and not hypersecreting adrenal adenomas. However, if a recommendation has to be given on the basis of the present evidences, we should suggest to biochemically and morphologically follow-up AI patients for at least 5 years.

Abstract
AIM To investigate the clinical and endocrinological characteristics of patients with adrenal incidentaloma (AI). MATERIALS AND METHODS This retrospective study enrolled 1941 AI patients hospitalized at the Department of Endocrinology, Chinese PLA General Hospital, Beijing, China, between January 1997 and December 2016. The patient gender, age at visits, imaging features, functional status, and histological results were analyzed. RESULTS Of the 1941 patients, 984 (50.70%) were men. The median age was 52 years (interquartile range: 44-69 years). 140 cases had bilateral AI. Endocrine evaluation showed that 1411 (72.69%) patients had nonfunctional tumor, 152 (7.83%) had subclinical Cushing syndrome (SCS), and 82 (4.33%) had primary hyperaldosteronism. A total of 925 patients underwent operation for removal of 496 cortical adenomas (53.62%), 15 adrenal cortical carcinomas (1.62%), and 172 pheochromocytomas (18.59%). The bilateral group had a higher proportion of SCS (18.57% versus 7.10%, P < 0.001, P = 0.006). A mass size of 46 mm was of great value in distinguishing malignant tumors from the benign tumors, with sensitivity of 88.2% and specificity of 95.5%. CONCLUSIONS We reported the baseline demographic and clinical characteristics of patients with AI in a large series from a single center in China.

Abstract
Background Extrahepatic manifestations of Echinococcus multilocularis are very rare, especially in the adrenal glands. To the best of our knowledge, only seven cases of adrenal alveolar echinococcosis have been reported, all from the Far East. All of these occurred exclusively in the right adrenal gland. Case presentation We report a rare case of an extrahepatic alveolar echinococcosis in an asymptomatic 78-year-old white man with an incidentaloma of his right adrenal gland. After surgical resection and medical treatment with albendazole no recurrence of the disease appeared at 1-year follow-up. Conclusions As the occurrence of Echinococcus multilocularis in Europe increases, alveolar echinococcosis should be included in the differential diagnosis of cystic adrenal incidentalomas.

Abstract
As cross-sectional abdominal imaging is used increasingly, adrenal incidentaloma (AI) are being found frequently and present a clinical dilemma. The vast majority are benign and non-functioning, but a minority represent incidentally found functional or malignant tumours. In this review we summarise the current clinical, biochemical and radiological investigation of AI and discuss recent advances that differentiate clinically inconsequential lesions from functional and/or malignant AI. Areas covered: Prevalence, natural history, biochemical and radiological assessment, indications for surgery and surgical provision. Expert commentary: Well established work-up of AI usually enables benign, non-functioning lesions to be differentiated from functioning and/or malignant AI. In indeterminate lesions recent advances in work-up such as urine steroid profiles measured by gas chromatography /mass spectrometry and functional imaging with 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET) in addition to standard investigations have improved characterisation of these lesions. The management of AI showing mild autonomous hypercortisolism without overt features of Cushing's syndrome remains controversial and is discussed in this review.

Abstract
: By definition, an adrenal incidentaloma is an asymptomatic adrenal mass detected on imaging not performed for suspected adrenal disease. In most cases, adrenal incidentalomas are nonfunctioning adrenocortical adenomas, but may also represent conditions requiring therapeutic intervention (e.g. adrenocortical carcinoma, pheochromocytoma, hormone-producing adenoma or metastasis). The purpose of this guideline is to provide clinicians with best possible evidence-based recommendations for clinical management of patients with adrenal incidentalomas based on the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. We predefined four main clinical questions crucial for the management of adrenal incidentaloma patients, addressing these four with systematic literature searches: (A) How to assess risk of malignancy?; (B) How to define and manage low-level autonomous cortisol secretion, formerly called 'subclinical' Cushing's syndrome?; (C) Who should have surgical treatment and how should it be performed?; (D) What follow-up is indicated if the adrenal incidentaloma is not surgically removed? SELECTED RECOMMENDATIONS: (i) At the time of initial detection of an adrenal mass establishing whether the mass is benign or malignant is an important aim to avoid cumbersome and expensive follow-up imaging in those with benign disease. (ii) To exclude cortisol excess, a 1mg overnight dexamethasone suppression test should be performed (applying a cut-off value of serum cortisol ≤50nmol/L (1.8µg/dL)). (iii) For patients without clinical signs of overt Cushing's syndrome but serum cortisol levels post 1mg dexamethasone >138nmol/L (>5µg/dL), we propose the term 'autonomous cortisol secretion'. (iv) All patients with '(possible) autonomous cortisol' secretion should be screened for hypertension and type 2 diabetes mellitus, to ensure these are appropriately treated. (v) Surgical treatment should be considered in an individualized approach in patients with 'autonomous cortisol secretion' who also have comorbidities that are potentially related to cortisol excess. (vi) In principle, the appropriateness of surgical intervention should be guided by the likelihood of malignancy, the presence and degree of hormone excess, age, general health and patient preference. (vii) Surgery is not usually indicated in patients with an asymptomatic, nonfunctioning unilateral adrenal mass and obvious benign features on imaging studies. We provide guidance on which surgical approach should be considered for adrenal masses with radiological findings suspicious of malignancy. Furthermore, we offer recommendations for the follow-up of patients with adrenal incidentaloma who do not undergo adrenal surgery, for those with bilateral incidentalomas, for patients with extra-adrenal malignancy and adrenal masses and for young and elderly patients with adrenal incidentalomas.

Abstract
INTRODUCTION Low incidence of adrenal cortical carcinoma in the general adult population has prompted a reevaluation of current protocol for the assessment of adrenal incidentalomas. OBJECTIVE To determine whether follow-up imaging for small (≤ 4 cm) incidental adrenal nodules is necessary for patients without known cancer. METHODS We performed a retrospective analysis of all patients found to have an incidental adrenal nodule on abdominal computed tomography (CT) scan during a 27-month period. The electronic medical record was reviewed to determine clinical outcomes in all patients with a minimum of 3 years of follow-up (mean follow-up = 6.7 years). Patients with a known primary cancer were excluded from the analysis unless they had a prior CT scan that documented an incidental adrenal nodule. Unenhanced CT attenuation was measured for all nodules, if available. RESULTS A total of 392 patients with an incidental adrenal nodule had a mean (standard deviation [SD]) clinical follow-up of 6.7 (2.7) years. There were 200 men and 192 women with a mean (SD) age of 66.0 (13.2) years. None of these patients developed primary adrenocortical carcinoma during the follow-up period.Two hundred forty of these patients also had a minimum 3 years of imaging follow-up (mean [SD], 6.4 [2.4] years; range, 3.1-13.6 years). There were 173 left-sided and 91 right-sided nodules on index CT scan. There was no significant difference in the mean (SD) rate of growth between left- and right-sided nodules (0.1 [0.8] mm/year vs 0.1 [0.8] mm/year, p = 0.58). Mean unenhanced CT attenuation of adrenal nodules did not affect the likelihood of adrenal malignancy during follow-up. CONCLUSION Patients with small incidental adrenal nodules do not require additional imaging to exclude the possibility of adrenocortical carcinoma.

Abstract
CONTEXT Incidental adrenal masses (or adrenal incidentalomas [AI]) are a common finding during imaging and are present in up to 5% of the computed tomography (CT) scans performed on the general population. The best way to manage these lesions is still under discussion. OBJECTIVE To evaluate recent literature and available guidelines regarding the work-up of AIs. EVIDENCE ACQUISITION We used a medical search engine to identify studies published in the past 5 yr regarding AIs. We also evaluated current guidelines and the most relevant papers published before 2010. EVIDENCE SYNTHESIS Unenhanced and contrast-enhanced CT, with laboratory tests to exclude functional lesions, are the most sensitive and specific methods currently available for the characterisation of adrenal masses. Magnetic resonance imaging, positron emission tomography-CT and fine-needle aspiration biopsy can be used as adjunct diagnostic tools in indeterminate lesions but are rarely indicated. In a relatively high number of indeterminate nodules, follow-up or surgery is suggested, although most of these lesions turn out to be benign. CONCLUSIONS Various imaging modalities, with CT being most important, are available to diagnose malignant and functional lesions in AIs. An improved identification of benign lesions is warranted to reduce the number of unnecessary surgeries and follow-up examinations in patients with benign lesions. PATIENT SUMMARY We performed a review of the literature on and guidelines for the management of incidental adrenal masses. It is possible to detect the presence of lesions that require surgery in the majority of cases. Follow-up is required for lesions that are not treated surgically.

Abstract
OBJECTIVE To investigate the outcome in patients with adrenal incidentaloma (AI). METHODS A retrospective evaluation of 637 patients with AI referred to a tertiary center over 8 years. Radiologic and hormonal evaluations were performed at baseline. Follow-up imaging was carried out if necessary, and hormonal evaluation was performed at 24 months according to national guidelines. RESULTS The mean age was 62.7 ± 11.6 years, and the mean AI size was 25.3 ± 17.0 mm at presentation. Hormonal evaluation revealed that 85.4% of all tumors were nonfunctioning adenomas, 4.1% subclinical Cushing syndrome (SCS), 1.4% pheochromocytoma, 1.4% primary hyperaldosteronism, 0.8% Cushing syndrome, 0.6% adrenocortical carcinoma, 0.3% congenital adrenal hyperplasia, 2.2% metastasis to adrenals, and 3.8% other lesions of benign origin. Bilateral tumors were found in 11%, and compared to unilateral tumors, SCS was more prevalent. Only 2 cases were reclassified during follow-up, both as SCS, but neither had had a dexamethasone suppression test performed at initial work-up. In patients diagnosed with an adrenal metastasis, 92.9% were deceased within 2 years. Excluding those with malignant tumors, 12.9% of patients died during the study period of up to 11 years due to other causes than adrenal. CONCLUSION Most AIs were benign, but a small fraction of tumors were functional and malignant. The prognosis of patients with adrenal metastasis was extremely poor, but otherwise, the mortality rate was similar to that for the general population. Follow-up of AIs <4 cm with an initial nonfunctional profile and benign radiologic appearance appears unwarranted, but screening for congenital adrenal hyperplasia should be considered.

Abstract
BACKGROUND The prevailing view that advocates long-term hormonal follow-up of adrenal incidentalomas is currently under debate. The purpose of the present study was to examine all adrenal incidentalomas presented during five years to a single centre. We hypothesized that 24-month biochemical follow-up in patients with an initial normal screening would fail to increase the sensitivity in finding hormone producing tumours. METHODS The present study is a retrospective register based cohort study of 194 patients referred to the Department of Endocrinology at Södersjukhuset between the years 2006-2010. Computerized medical records were used to find and extract information on patients with newly discovered adrenal incidentalomas. The sensitivity, specificity, positive predictive value and negative predictive value were calculated to evaluate the validity of an initial normal screening when used to identify individuals with hormone producing tumours. RESULTS Of the incidentalomas 94% consisted of benign, non-functioning tumours. Three patients were diagnosed with cortisol hypersecretion and one with pheochromocytoma. The sensitivity, specificity, positive predictive value and negative predictive value of an initial complete negative screening to predict a hormone producing tumour were 100%, 63%, 12% and 100%, respectively. CONCLUSION Patients with an initially normal hormonal screening may not need further biochemical follow-up.

Abstract
BACKGROUND Subclinical Cushing's syndrome (SCS) is a condition of biochemical cortisol excess without the classical clinical features of overt hypercortisolism; it may be associated with some consequences of metabolic syndrome. The most appropriate treatment remains controversial. This study aimed to assess the outcomes of adrenalectomy for SCS. METHODS A systematic review was performed. MEDLINE, Embase and Cochrane Databases (1980-2013) were searched for studies reporting the outcomes of unilateral adrenalectomy with respect to hypertension, diabetes, dyslipidaemia, obesity and osteoporosis in patients with SCS. Studies with a questionable diagnosis of SCS, bilateral adrenal involvement and insufficient data were excluded. RESULTS Of the 105 papers screened, seven were selected; there were six retrospective studies and one randomized clinical trial, including 230 patients. Data analysis was limited by heterogeneity in definition of SCS and endpoints. Hypercortisolism was cured in all operated patients. Laparoscopy was the preferred approach, with a morbidity rate of 0·8 per cent. A beneficial effect of surgery on blood pressure, glucometabolic control and obesity was evident in all studies, with cure or improvement in 72, 46 and 39 per cent of patients respectively, compared with conservative management. The results for lipid metabolism were equivocal, because of a decrease in triglyceridaemia but discordant effects on cholesterol metabolism among the different studies. No beneficial effects on osteoporosis were found. CONCLUSION Laparoscopic adrenalectomy seems to be beneficial in reversing several metabolic effects of hypercortisolism, with a low morbidity rate. However, the heterogeneity and low quality of the available studies preclude definitive recommendations.

Abstract
BACKGROUND The prevalence of adrenal incidentalomas is increasing with the aging of the population and the use of high resolution imaging technics. Current protocols propose a comprehensive monitoring of their functional and morphological state, but with no conclusive clinical evidence that endorses it. METHOD Retrospective study of 96 patients diagnosed with adrenal incidentaloma between 2008 and 2012. We evaluated clinical, functional and imaging at baseline and during follow-up. RESULTS Initially, 9 cases were surgically removed: 4 due to hyperfunction (2 Cushing syndromes and 2 pheochromocytomas) and 5 due to size larger than 4cm. During follow-up one case of pheochromocytoma was diagnosed and another grew more than 1cm, needing surgery. In 98.86% of nonfunctional and benign lesions, there was no functional and/or morphological changes in the final evaluation. CONCLUSIONS The results of our study challenge the validity of current diagnostic-therapeutic protocols of incidentalomas, which should be reassessed in prospective studies taking into account efficiency characteristics.

Abstract
Adrenal incidentalomas (AIs) are common and guidelines recommend testing to exclude functioning lesions and malignancy. Their increasing prevalence results in several investigations that are usually conducted in the endocrinology clinic. In 2011, we audited the prevalence and management of AIs identified on computed tomography (CT) imaging of abdomen over 1 calendar month. Consequently, a decision pathway for adrenal lesions was introduced in the radiology department of the Royal Free London Hospital. One year later, we re-audited the local practice. In total, 690 CT scans were reviewed in 2011 compared with 1,264 in 2012. In 2011, 17 (2.46%) patients with AIs were identified, and 26 (2.01%) in 2012. Of those, 1.01% in 2011 and 0.95% in 2012 had newly identified AIs. Only a few patients had been tested to exclude a functional lesion and there was inconsistent terminology in reporting adrenal lesions. Therefore, we support comprehensive reporting of AIs and a selective testing strategy.

Abstract
BACKGROUND Measurements of attenuation (in Hounsfield units [HU]) and contrast wash-out are widely used to characterize adrenal lesions as benign or indeterminate/malignant at computed tomography (CT). Clinical experience suggests that such measurements of adrenal lesions may vary over time and between observers, making evaluation difficult. PURPOSE To investigate the change over time of adrenal lesion size, attenuation, and contrast wash-out at CT, to determine inter-observer variability, and to analyze other factors underlying the variability. MATERIAL AND METHODS In a cohort of patients, with or without malignant disease, undergoing CT, adrenal lesions were prospectively analyzed. Lesions with growth >20% or >5 mm over 6 months were excluded. Non-enhanced attenuation and contrast medium wash-out over 2-year follow-up were analyzed. An inter-observer analysis with five observers and a phantom study of eight different CT scanners were performed to assess measurement variability. RESULTS Mean adrenal lesion non-enhanced attenuation values decreased by 0.5 HU/year during follow-up. Using 10 HU or 40% relative wash-out as threshold values for benign versus indeterminate lesions, 27 (20%) and 39 (29%) of 136 lesions, respectively, would be reclassified at some occasion during follow-up. In the observer analysis 37 of 40 lesions demonstrated agreement between all observers, using established threshold values. The phantom study showed an intra-scanner variability of 1-3 HU, but an inter-scanner variability of up to 8 HU for water. CONCLUSION The clinically widespread use of specific attenuation threshold values for characterizing adrenal lesions must be used with great caution, considering that multiple factors, related to patient, equipment, scanning technique, and observer influence the outcome.

Abstract
The aim of this study was to assess patient-reported impacts and health-related quality of life (HRQL) of a 2-year follow-up programme in a large cohort of patients with stationary, non-functioning, adrenal incidentalomas (AIs) in western Sweden. 145 patients (mean age 68 years, 62 % females) with AI from a prospective study in western Sweden were studied. All had completed a 2-year follow-up programme by November 2007, without evidence of adrenal malignancy or hormone over-production. To evaluate patient-reported impacts and HRQL, an eight-item adrenal incidentaloma impact questionnaire was used retrospectively, together with the hospital anxiety and depression scale, and the short form-36. There were 111 patients (mean age 67 years, 63 % females) who responded to the questionnaire (response rate 77 %). 77 % reported that the AI diagnosis had caused them to be worried; however, fewer than 20 % had thought about the lesion often during the follow-up programme, and only 3 % had felt that it had a large impact on their current daily life. Only 4 % stated that the follow-up programme had been a negative experience, nevertheless 10 % reported a negative impact on their HRQL during the follow-up programme. Only 2 % stated that release from follow-up caused worry to any degree. In total, 29 % had possible anxiety, and 30 % had possible depression, probably reflecting significant co-morbidity. Possible anxiety correlated with a more negative experience of the follow-up programme. In conclusion, the 2-year follow-up programme for patients with AI was well tolerated. Nonetheless, a small number remained worried throughout follow-up, suggesting the need for tailored counselling in individual patients to ameliorate negative impacts of follow-up.

Abstract
BACKGROUND Adrenal masses are common incidental findings on radiologic imaging. The association between malignancy and hormonal hyperactivity found in incidentally discovered adrenal tumors, however, remains unclear. METHODS A retrospective analysis of prospectively collected data from patients who underwent adrenalectomy for incidentally discovered adrenal tumors at a single institution. Outcomes and operative data were compared by univariate analysis. Area under the curve was used to analyze the effect of tumor size in predicting malignancy. RESULTS There were 49 patients who initially presented with adrenal incidentalomas that underwent adrenalectomy. Most patients were Caucasian women with an average age of 51 ± 14 years. Of this group, 24 patients underwent resection for hyperfunctioning adrenal glands. There were no significant differences in malignancy rates between hyperfunctional and nonfunctional tumors (4.1% vs. 12.0%, P = 0.32). On final histopathology, there were four patients with adrenal malignancies: two adrenocortical carcinomas and two metastatic from renal carcinoma. Only one patient with a hyperfunctioning adrenal tumor had underlying malignancy. Overall, invasion of adjacent structures (P < 0.001), presence of lymphadenopathy (P = 0.02), metastasis (P = 0.03), irregular tumor margins (P = 0.01), heterogeneity (P = 0.05), and tumor size >6 cm (P = 0.04) on radiologic imaging were strongly associated with malignancy in adrenal incidentalomas. CONCLUSIONS The risk of concomitant malignancy and hormonal hyperactivity in adrenal incidentalomas is very low. Tumor size (>6 cm) and radiographic features remain the most important predictors of adrenal malignancy, regardless of tumor function.

Abstract
Adrenal incidentaloma is a common clinical problem and its prevalence, in radiological studies, comes close to that of autoptic data as a result of imaging technological advances. The diagnostic challenge is to distinguish the majority of benign lesions from other masses, either malignant or hormone secreting, which require further therapy. The imaging evaluation (unenhanced CT and MRI) can differentiate malignant to benign lesions because the benign lesions have high lipid content. All patients should be tested for hypercortisolism and pheochromocytoma whereas aldosteronism should be tested in hypertensive patients only. The optimal diagnostic management for adrenal incidentaloma is still controversial, and the endocrinologist must devise a cost-effective approach taking into account the extensive endocrine work-up and imaging investigations that may be necessary. A tailored strategy may be based on the selection of patients at increased risk who require a careful and extensive follow-up among the vast majority of patients who require a simplified follow-up.
