Abstract
The chronic excess of glucocorticoids results in Cushing's syndrome. Cushing's syndrome presents with a variety of signs and symptoms including: central obesity, proximal muscle weakness, fatigue striae, poor wound healing, amenorrhea, and others. ACTHindependent Cushing's syndrome is usually due to unilateral adenoma. A rare cause of it is bilateral adrenal adenomas. In this paper we report a case of a 43-year-old woman with Cushing's syndrome due to bilateral adrenal adenoma.

Abstract
Background Adrenal incidentalomas are often found during investigation for another tumor or unrelated problems. Except for adrenal myelolipoma (second most common primary adrenal incidentaloma following adrenocortical adenomas), adrenal lipomatous tumors are uncommon generally and are often described as case reports in the literature. Since the amount of fat is variable, without the help of advanced imaging techniques, some adrenal lipomatous tumors may be misdiagnosed before pathologic examination. Herein, we report a case of adrenal adenoma with myelolipomatous metaplasia that was excised as a periceliac mass in the setting of recurrent pancreatic cyst. Case report A 45-year-old Iranian woman with hypertension and end-stage renal disease presented with recurrence of a pancreatic cyst (previous pathologic report was mucinous cyst adenoma). During exploratory laparotomy, the mentioned pancreatic cyst was tightly attached to the stomach and jejunum. There was also a periceliac round rubbery lesion (firstly diagnosed by endoscopic ultrasound) that was excised for ruling out malignancy. Histologic examination of the periceliac mass was found to be adrenocortical adenoma with foci of myelolipomatous metaplasia. The pancreatic cyst histology was just a pseudocyst. Conclusion Our case highlights the significance of complete evaluation of incidental findings before surgical intervention, even in the setting of another primary tumor. Myelolipoma and myelolipomatous change (metaplasia) are two different entities. Although very similar as to pathogenesis, there are still some differences.

Likelihood ratio of computed tomography characteristics for diagnosis of malignancy in adrenal incidentaloma: systematic review and meta-analysis. J Diabetes Metab Disord 2016; 15:12.

Abstract
Purpose To propose an evidence based diagnostic algorithm using mass characteristics to determine malignancy in patients with adrenal incidentaloma by CTscan. Methods A systematic review in Medline, Scopus, relevant reference books and desk searching was performed up to January 2016 with relevant reference checking. The summery estimates of sensitivity, specificity, positive and negative likelihood ratio of different characteristics were calculated in two groups of the articles investigating the cases without previous malignancy and the articles investigating the oncologic cases. Results Thirty six articles were included in this study. In the first group with no history of malignancy a positive and negative LR of 3.1 and 0.13 in 4 cm threshold and positive and negative LR of 2.85 and 0 in 10HU density were found. In the second group with history of malignancy positive and negative LR of 2.3 and 0.27 in 3 cm threshold and positive and negative LR of 3.6 and 0.08 in 20HU density were resulted. Conclusion The results retrieved in this study considering the limitations show that adrenal incidentaloma with a size less than 4 cm or a mass larger than 4 cm with density less than 10HU in the first group can be managed with imaging follow up. For masses larger than 4 cm with density more than 10HU another diagnostic procedure should be performed. In the second group an adrenal mass larger than 3 cm or less than 3 cm with density more than 20HU should go under operation. But masses smaller than 3 cm with less than 20HU density can be followed by imaging.

Abstract
The term adrenal incidentaloma (AI) is usually defined as an adrenal mass unexpectedly detected through an imaging procedure performed for reasons a priori unrelated to adrenal dysfunction or suspected dysfunction. The preferred approach to their management in terms of diagnosis, follow-up, and treatment remain controversial despite a state-of-the-science conference sponsored by the U.S. National Institutes of Health. Although most experts' recommendations tend to be relatively minor variations of the conference's approach, dissenting voices have been heard. Despite their frequent appearance, the challenge remains to recognize and treat the small percentage of AI that do pose a significant risk, either because of their hormonal activity or because of their malignant histology, while leaving the rest alone. Although the differential diagnosis of an incidentally discovered mass is quite extensive, most AIs are non-secreting cortical adenomas. The noninvasive differentiation of benign and malignant lesions depends upon imaging characteristics, and sometimes radiologic diagnosis can be definitive, but often it is not, Among function lesions, autonomous cortisol production seems to be the most common and may be associated with increased cardiovascular risk and clinical features of the "metabolic syndrome." Follow-up of cases in which a specific diagnosis is not made initially involves assessment for growth and development of hormonal function, but even here, controversy about the extent of evaluation persists.

Abstract
Adrenal disorders may manifest during pregnancy de novo, or before pregnancy undiagnosed or diagnosed and treated. Adrenal disorders may present as hormonal hypofunction or hyperfunction, or with mass effects or other nonendocrine effects. Pregnancy presents special problems in the evaluation of the hypothalamic-pituitary-adrenal axis in addition to the usual considerations. The renin-angiotensin-aldosterone axis undergoes major changes during pregnancy. Nevertheless, the common adrenal disorders are associated with morbidity during pregnancy and their management is more complicated. A high index of suspicion must be maintained for these disorders lest they go unrecognized and untreated.

Abstract
Pheochromocytoma is a tumor of the chromaffin cells in the adrenal medulla and sympathetic paraganglia, which synthesizes and secretes catecholamines. Norepinephrine, epinephrine, and dopamine all act on their target receptors, which causes a physiologic change in the body. High circulating levels of catecholamines can lead to severe hypertension and can have devastating effects on multiple body systems (eg, cardiovascular, cerebrovascular), and can lead to death if untreated. Although surgical treatment represents the only modality of ultimate cure, pharmacologic preoperative treatment remains the mainstay of successful outcome.

Abstract
BACKGROUND The term adrenal incidentaloma (AI) indicates an adrenal mass lesion > 1 cm in diameter discovered during testing for conditions unrelated to adrenal disease. The overall prevalence of these lesions ranges between 3% and 10%. Their incidence increases with age, and it is clinically important to identify AI associated with hormonal activity and/or malignant potential. DESIGN A detailed Medline search of all English language articles related to AI was carried out, and the clinical implications related to their hormonal activity and malignant potential are discussed. RESULTS The subclinical hypercortisolism observed in a significant percentage of patients with AI is associated with some of the detrimental effects of continuous autonomous cortisol secretion, including a higher prevalence of hypertension, dyslipidaemia, impaired glucose tolerance or type 2 diabetes mellitus and an increased risk for osteoporotic fractures. However, it remains to be proven whether treatment to reverse subtle glucocorticoid excess is beneficial. Clinically silent phaeochromocytomas and primary adrenal cancer are conditions associated with significantly high morbidity and mortality and require urgent treatment, while the prevalence and clinical significance of autonomous mineralocorticoid secretion are less clearly defined. Size and radiological features are the main predictors of malignant potential. CONCLUSIONS Patients harbouring AI should be evaluated for the possibility of malignancy and/or subclinical hypercortisolism which is associated with cardiovascular risk and bone loss. However, in the absence of prospective controlled studies correlating biochemical activity with end-organ complications, the long-term consequences of AI remain uncertain and their management remains largely pragmatic.

Abstract
BACKGROUND Adrenal lesions are discovered in acromegaly more frequently than in general population, without relationship with primary disease. Some patients, carriers of aryl hydrocarbon receptor interacting protein (AIP) gene mutations, developed an adrenal neoplasm. AIM To evaluate the role of metabolic and genetic aspects and the follow-up of adrenal nodules in acromegaly. MATERIAL AND METHODS We studied 69 acromegalic patients (30 male and 39 female, 56 ± 15 yr) who had been referred to the Endocrinology Unit of Padua. In all patients we determined body mass index (BMI) and waist-to-hip ratio (WHR); we performed an oral glucose tolerance test (OGTT) whenever possible. If adrenal computed tomography revealed a lesion, the patient underwent an endocrine and genetic study. RESULTS Adrenal lesions were identified in 14 patients and were not related to gender, duration of disease, GH or IGF-I concentrations, basal and after-OGTT glucose and insulin levels, log(HOMA-IR) and Quantitative Insulin Sensitivity Check Index (QUICKI) values, whereas BMI and WHR were higher in patients with adrenal lesions. Baseline endocrine and radiological study revealed benign lesions; during mean 4-yr follow-up none of the patients showed hormone excess, even though some lesions increased in size. We did not find any mutation in AIP gene, except heterozygous silent alteration (T48T). CONCLUSIONS The frequency of non-functioning adrenal lesions in acromegaly is not associated with the considered aspects, except BMI and WHR. The prolonged follow-up showed that these lesions have a tendency to increase in size independently of the control of acromegaly, so a morphological follow- up is recommended.

Abstract
UNLABELLED Adrenal incidentaloma (AI) is frequently found in patients with a history of malignancy and, as such, is not always considered a true incidental finding. OBJECTIVE To compare the short-term clinical and biochemical behavior of adrenal incidentalomas between oncology and non-oncology patients. DESIGN Retrospective comparative case series of 100 consecutive patients with adrenal incidentaloma, followed from 1995 to 2005 in the endocrinology clinic of a tertiary university medical center. MAIN OUTCOME A history of malignancy was present in 32 patients. Median follow-up was 24 months. Mean tumor size was 24+/-10 mm. Endocrine evaluation yielded functional abnormalities in 12.2% (subclinical Cushing's 7.4%, Cushing's syndrome 1.1%, hyperaldosteronism 1.3%, pheochromocytoma 3.6%). During follow-up, adrenal function remained unchanged in all patients, but tumor growth was seen in 12.5%. Compared to the non-oncology patients, the oncology group had a higher mean age (67.5+/-9.6 vs 59.4+/-1.3 yr, p=0.001) and greater tumor growth (23.3% vs 7%, p=0.035), with no significant differences for tumor size, functional abnormalities, and extent of change in tumor size. Surgery was performed in 9 patients (3 oncologic) and revealed metastasis in one. None of the other patients had clinical or radiological findings suggesting adrenal malignancy. CONCLUSION Our study suggests a similar clinical behavior of adrenal incidentaloma in oncology and non-oncology patients. More studies are needed to assist clinicians in selecting oncology patients with AI for whom a more conservative approach can be recommended.

Abstract
A 31-year-old woman was incidentally found to have a large right adrenal mass by computed tomography imaging and underwent a workup that included endocrinological evaluation and positron emission tomography imaging. Laboratory results revealed the mass to be non-functioning. Imaging studies revealed a 9-cm heterogeneous mass that was not FDG avid. Because of concern for adrenal cortical carcinoma, the patient underwent a successful right adrenalectomy. Pathology examination demonstrated an 11-cm circumscribed mass consisting of uniform spindle cells without nuclear pleomorphism, necrosis, or mitotic activity. The diagnosis of leiomyoma was supported by a panel of immunohistochemical stains. Adrenal leiomyomas have been reported in the literature, although most are small and not preoperatively suspicious for malignancy. This case illustrates that benign tumors such as leiomyomas, when large and heterogeneous on imaging, can clinically mimic adrenal cortical carcinomas and should be included in the differential diagnosis of adrenal incidentalomas.

Abstract
Endocrine hypertension is a term used for states in which hormone derangements result in clinically significant hypertension. The adrenal glands are the most likely culprits, due either to an excessive production of mineralocorticoids, catecholamines or glucocorticoids. The term 'adrenal incidentaloma' indicates an adrenal mass discovered accidentally during testing or treatment for other clinical conditions unrelated to any suspicion of adrenal disease. In particular, when an adrenal mass is discovered in a hypertensive subject, physicians must check whether the patient has pheochromocytoma, glucocorticoid excess or primary aldosteronism. Although most adrenal masses are non-hypersecretory adenomas, hormone screening can reveal a significant number of cases of clinically unsuspected hormone-secreting adrenal tumors. If the clinical history or physical examination of a patient with unilateral incidentaloma shows signs and symptoms suggestive of glucocorticoid, mineralocorticoid, adrenal sex hormone or catecholamine excess, which is confirmed biochemically, the treatment of choice is often adrenalectomy. In cases where surgery is contraindicated or the lesions are unresectable, medical treatment may be an option.

Abstract
INTRODUCTION Adrenal incidentalomas are unsuspected, clinically silent adrenal lesions discovered incidentally by imaging tests performed a priori for problems unrelated to the adrenal glands. The aim of this study was to present a series of incidentalomas and review the diagnostic process and treatment techniques. PATIENTS AND METHOD Of a series of 63 patients studied and/or treated for adrenal disease, there were 34 patients with adrenal incidentalomas. The mean age of the patients with incidentaloma was 50.6 years. There were 23 women (67.6%) and 11 men (32.3%). All patients underwent hormonal investigations to rule out hyperfunction. Imaging techniques consisted of ultrasonography, computed tomography (CT) and/or magnetic resonance imaging (MRI) to determine the size and characteristics of the lesion. In patients with an indication for surgery, the lateral transabdominal approach was used in laparoscopic surgery and the anterior approach was used in open surgery. RESULTS Of the 34 patients, 23 patients (67.6%) (18 women and 5 men) with a mean age of 50.9 years underwent surgery. The mean tumoral diameter was 10.18 cm. Incidentalomas were located in the right adrenal gland in 16 patients and in the left adrenal gland in 7 patients. Laparoscopic surgery was performed in 9 patients (39.1%) and open surgery was performed in the remaining 14 (60.8%). The mean length of hospital stay was 8.6 days in open surgery and 4 days in laparoscopic surgery. Complications consisted of pneumonia in 2 patients (8.6%). There was no intraoperative mortality in the series. Surgery was not performed in 11 patients (32.3%) (5 women and 6 men) with a mean age of 56.3 years. The mean size of the tumor in these patients, identified by CT, was 2.5 cm. These patients underwent subsequent monitoring with a mean follow-up of 32 months. CONCLUSIONS Due to the high resolution of ultrasonography, CT and MRI, as well as the greater number of radiological investigations performed, identification of adrenal incidentalomas has increased. In our series these tumors represented 53.9% of adrenal disease.
