Abstract
Incidental findings are common in the evaluation of surgical patients. Understanding the appropriate assessment and management of these frequent occurrences is important for the provision of comprehensive quality care. This review details the epidemiology, considerations, and recommendations for management of common incidental manifestations in surgical patients, including Meckel diverticulum, adrenal incidentaloma, thyroid nodule, solitary pulmonary nodule, small bowel intussusception, gallstones, and incidental appendectomy.

Abstract
Adrenal collision tumors refer to coexistence of two adjacent, but histologically distinct, neoplasms involving the adrenal gland without histologic admixture at the interface. Myelolipoma is a rare but benign neoplasm. As its name implies, displays both mature adipose tissue and hematopoietic elements. These are usually unilateral and asymptomatic. Schwannomas, tumors derived from the peripheral nerve sheath, are also uncommon lesions in the adrenal gland. Here, we present a rare case of a 65-year-old male with clinical history of abdominal aortic aneurysm who was found to have a 13-cm “incidentaloma” by interventional radiologist during his aortic endograft control. Giving the size of the mass, team decided to excise it, and histopathological examination was performed. While most incidentally discovered adrenal tumors are benign, surgical excision is recommended in large lesions to exclude malignancy, avoid hemorrhage, and/or acute adrenal insufficiency. Given the rarity of such entity, its clinical course and prognosis remains unclear.

Abstract
BACKGROUND Because adrenal angiomyelolipoma (AAML) is rare and uniformly benign, the indications for surgery are ill defined. METHODS Among a series of 156 patients with adrenal pathologies surgically treated between 2013 and 2018, 12 patients were operated with the diagnosis of an AAML. The clinical as well as imaging parameters forming the individual indications for surgery were analyzed. RESULTS Preoperative diagnosis consistent with AAML was made in all 12 patients. The mean size of surgically removed AAML was 82.3 mm (45-150 mm). Gender and affected side were evenly distributed. Local symptoms but lack of radiological signs suspicious for malignancy or size increase were observed in 4 of 12 patients (group 1, 33%). In contrast, 4 of 12 patients (group 2, 33%) showed radiological signs suspicious for malignancy but lacked local symptoms. Additional 4 of 12 patients (group 3, 33%) showed both local symptoms and radiological signs suspicious for malignancy. Patients with local symptoms harbored significantly larger tumors compared to those patients that lacked local symptoms (93.9 mm ± 32.8 vs. 59.3 mm ± 2.7, p = 0.021). Patients with radiologically suspicious signs were older (60 years ± 9.9 vs. 53 years ± 5.4, p > 0.05), and time to surgery was shorter (4.4 months ± 3 vs. 6.0 months ± 3.0, p > 0.05). Importantly, surgical approach was not influenced by tumor size (p = 0.65). However, patients with suspicious imaging were more likely to be operated by conventional open approach (4 of 8 vs. 0 of 4, p = 0.08). The minimal invasive approach was associated with shorter hospital stay (7 days, ± 1.3 vs. 14.2 days, ± 8.8, p = 0.038). All lesions that showed radiological signs suspicious for malignancy proved benign in final histology. CONCLUSION Large AAML present a clinical challenge. The presence of local symptoms and/or radiological signs suspicious for malignancy identifies three groups of patients that define the concept of an individualized indication for surgery in AAML. A minimal invasive approach can be advocated even for large AAML with radiological signs suspicious for malignancy.

Abstract
Adrenalectomy is the standard of care for management of many adrenal tumor types and, in the United States alone, approximately 6000 adrenal surgeries are performed annually. Two general approaches to adrenalectomy have been described; (1) the open approach, in which a diseased adrenal is removed through a large (10-20 cm) abdominal wall incision, and (2) the minimally invasive approach, in which laparoscopy is used to excise the gland through incisions generally no longer than 1-2 cm. Given these disparate technique options, clear preoperative characterization of those specific disease features that inform selection of adrenalectomy approach is critically important to the surgeon. Because most of these features are directly assessed via preoperative abdominal imaging, in particular computed tomography (CT) scanning, a clear mutual understanding among surgeons and radiologists of those adrenal tumor features impacting operative approach selection is vital for planning adrenal surgery. In this context, we review the preoperative CT imaging features that specifically inform adrenalectomy approach selection, provide illustrative examples from our institution's imaging and surgical archives, and provide a stepwise guide to both the open and laparoscopic adrenalectomy approaches.

Abstract
Due to the fact that overweight or obesity is accompanied by hormonally active adrenal tumors: Cushing Syndrome-(CS) and Subclinical Cushing Syndrome (SCS), it is of high interest the correlation between different adipokines and cytokines secreted by adipose tissue, with metabolic disorders and hormonal activity in this group. Even in non-functioning adrenal incidentalomas (NFAI) elevated risk for cardiovascular disease and metabolic syndrome was demonstrated. The aim of the study was to investigate plasma adiponectin, leptin, resistin, tumor necrosis factor α (TNFα), interleukin 6 (IL6) and monocyte chemoattractant protein 1 (MCP1) levels in patients with NFAIs and healthy subjects. The study included 18 NFAI patients and 18 healthy subjects. The groups were homogeneous in terms of age, sex and body mass index (BMI). Patients with NFAI showed significantly higher circulating levels of pro-inflammatory cytokines compared to healthy controls (MCP 1: p < 0.001; TNFα p = 0.021; IL6 p = 0.012). On the other hand, adiponectin concentration was significantly lower in the NFAI group (p = 0.034). The serum leptin and resistin concentrations did not differ significantly between the two groups. Acquired results were not dependent on glucocorticoid and catecholamine secretion in NFAI patients. Also, there were no clear correlations between BMI and cytokine levels. It is possible that increased risk for cardiovascular and metabolic diseases reported in NFAI patients is at least partially dependent on adipose tissue activity.

Abstract
Introduction Incidentaloma is defined as an tumor diagnosed accidentally using imaging studies performed due to other indications. The aim of this paper was to describe the diagnostic and treatment problems experienced by patients with adrenal incidentaloma in a clinical practice. Material and methods In years 2009-2012 there were 33(16,5%) adrenal tumors diagnosed incidentally out of 200 cases treated due to adrenal pathology. The group consisted of 54 patients aged 27-77. In 15(45,5%) patients the diagnosis was made based on ultrasound examination, while in 18(54,5%) the tumor was visualized in CT/MRI. Results Only after the diagnostics was finalized, in which in all cases no signs of hormonal activity were detected, 26(78,8%) patients were qualified for the surgery. In 7(21,2%) cases no indications for such a management were found. The latter group was followed-up and in all patients the indications for the surgery arose due to enlargement of the tumor or/and the existence of hormonal activity. Our observations suggest that the incident finding of adrenal tumor is an indication of long-term observation. The analysis of our material shows that all patients observed needed surgical treatment. Conclusions The small adrenal tumors under follow-up have a tendency to enlarge and acquire hormonal activity. Long-term observation significantly increases the costs of treatment in that group, which eventually results in surgical management.

Abstract
OBJECTIVE We present a case of an adrenal hemangioma, an uncommon cause of an adrenal mass, and review the clinical presentation, work-up, and management of adrenal incidentalomas. BACKGROUND A 64-year-old male was found to have a right adrenal incidentaloma during work-up for elevated liver transaminase levels, later found to be from hepatitis C. The mass was suspicious for adrenocortical carcinoma on CT imaging. Biochemical evaluation revealed no evidence of function. He underwent an open right adrenalectomy. The mass was found to be an adrenal hemangioma on histopathologic analysis. METHODS This is a case report with pertinent review of the diagnosis and management of adrenal incidentalomas. RESULTS Adrenal hemangiomas are rare, benign, nonfunctional tumors typically found during imaging for other reasons. As illustrated by this case, they appear similar to adrenocortical carcinoma on CT imaging. The diagnosis is usually not made prior to surgical resection. CONCLUSION Adrenal hemangioma is a rare nonfunctional adrenal incidentaloma that displays atypical features on CT imaging. The suspicion for adrenocortical carcinoma usually prompts adrenalectomy.

Abstract
BACKGROUND Audit is a clinical instrument of government characterized by a whole process of evaluation inter pares to improve medical behaviors in the clinical practice. Different endocrinopathies are underestimated in the clinical and diagnostics practice but they can be a real problem in patients admitted in the departments of Internal Medicine. The adrenal incidentaloma is an accidental discovery with an incidence equal to 4% in radiologic studies but it's rarely considereted in the internal disorders. In the departments of Internal Medicine are hospitalized each year approximately 1450,000 patients and 58,000 about them show a surrenalic lesion identified with CT or MRI as Adrenal Incidentaloma. METHODS Through a search in the radiological archives, were reviewed all abdominal CT performed in the year 2012 in 8 departments of Internal Medicine of 8 Italian public hospitals. They also examined all medical records of these patients to value clinical management of the adrenal masses and the real incidence of the adrenal incidentaloma. RESULTS Distribution of pathological results show an important incidence about adrenal incidentaloma in Italian patients although this pathology is represented as a rare disease and its clinical and economic burden are significant. Many questions remain unanswered as the association between duration and severity of the disease, morbidity and how the dimensions affecting it. These results need to be supported by important studies with long follow-up to realize an easy diagnosis. CONCLUSIONS The results of this audit confirm the real incidence of this pathology in the internistic patients and the final target is to implement changes about therapeutic diagnostic pathway of the hospital patients in the internal medicine departments.

Abstract
Purpose: Adrenal incidentalomas must be differentiated from adrenocortical cancer (ACC). Currently, size, growth, and imaging characteristics determine the potential for malignancy but are imperfect. The aim was to evaluate whether urinary small molecules (<800 Da) are associated with ACC.Experimental Design: Preoperative fasting urine specimens from patients with ACC (n = 19) and benign adrenal tumors (n = 46) were analyzed by unbiased ultraperformance liquid chromatography/mass spectrometry. Creatinine-normalized features were analyzed by Progenesis, SIMCA, and unpaired t test adjusted by FDR. Features with an AUC >0.8 were identified through fragmentation patterns and database searches. All lead features were assessed in an independent set from patients with ACC (n = 11) and benign adrenal tumors (n = 46) and in a subset of tissue samples from patients with ACC (n = 15) and benign adrenal tumors (n = 15) in the training set.Results: Sixty-nine features were discovered and four known metabolites identified. Urinary creatine riboside was elevated 2.1-fold (P = 0.0001) in patients with ACC. L-tryptophan, Nε,Nε,Nε-trimethyl-L-lysine, and 3-methylhistidine were lower 0.33-fold (P < 0.0001), 0.56-fold (P < 0.0001), and 0.33-fold (P = 0.0003) in patients with ACC, respectively. Combined multivariate analysis of the four biomarkers showed an AUC of 0.89 [sensitivity 94.7% (confidence interval {CI}, 73.9%-99.1%), specificity 82.6% (CI, 68.6%-92.2%), PPV 69.2% (CI, 48.2%-85.6%), and NPV 97.4% (CI, 86.5%-99.6%)] for distinguishing ACC from benign tumors. Of the four, creatine riboside and four unknown features were validated. Creatine riboside, Nε,Nε,Nε-trimethyl-L-lysine, and two unknown features were elevated in ACC tumors.Conclusions: There are unique urinary metabolic features in patients with ACC with some metabolites present in patient tumor samples. Urinary creatine riboside can differentiate benign adrenal neoplasms from ACC. Clin Cancer Res; 23(17); 5302-10. ©2017 AACR.

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
INTRODUCTION/AIM This study aimed to determine if laparoscopic adrenalectomy (LA) is feasible for the treatment of adrenal malignancies and metastasis, and to review the final pathology findings in order to clarify the indications for surgery. MATERIALS AND METHOD The medical records of all patients that underwent LA at 3 university hospitals between January 1, 2008, and May 1, 2015, were retrospectively reviewed. RESULTS In total, 189 laparoscopic adrenalectomies were completed successfully. Mean duration of surgery was 79.3 ± 38.6 min and mean estimated intraoperative blood loss was 39.9 ml. Intraoperatively, 4 patients had major complications: spleen injury (n = 1), renal vein injury (n = 2) and diaphragm injury (n = 2). Histopathological examination showed that there were 20 different types of lesions. Surgical margins (SMs) were tumor free in 95.2% of the patients. Moreover, SMs were tumor free in all patients with adrenocortical carcinomas; however, positive margins were noted in 7 of 23 patients (30.4%) with malignant adrenal tumors. CONCLUSIONS The present findings support the use of laparoscopy for metastatic adrenal masses, despite a high positive margin rate. LA is a safe, feasible and cost-effective procedure for the management of benign and malignant adrenal masses.

Abstract
AIM: To review current applications of the laparoscopic surgery while highlighting the standard procedures across different fields.
METHODS: A comprehensive search was undertaken using the PubMed Advanced Search Builder. A total of 321 articles were found in this search. The following criteria had to be met for the publication to be selected: Review article, randomized controlled trials, or meta-analyses discussing the subject of laparoscopic surgery. In addition, publications were hand-searched in the Cochrane database and the high-impact journals. A total of 82 of the findings were included according to matching the inclusion criteria. Overall, 403 full-text articles were reviewed. Of these, 218 were excluded due to not matching the inclusion criteria.
RESULTS: A total of 185 relevant articles were identified matching the search criteria for an overview of the current literature on the laparoscopic surgery. Articles covered the period from the first laparoscopic application through its tremendous advancement over the last several years. Overall, the biggest advantage of the procedure has been minimizing trauma to the abdominal wall compared with open surgery. In the case of cholecystectomy, fundoplication, and adrenalectomy, the procedure has become the gold standard without being proven as a superior technique over the open surgery in randomized controlled trials. Faster recovery, reduced hospital stay, and a quicker return to normal activities are the most evident advantages of the laparoscopic surgery. Positive outcomes, efficiency, a lower rate of wound infections, and reduction in the perioperative morbidity of minimally invasive procedures have been shown in most indications.
CONCLUSION: Improvements in surgical training and developments in instruments, imaging, and surgical techniques have greatly increased safety and feasibility of the laparoscopic surgical procedures.

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 determine the incidence of adrenal incidentalomas (AIs) in a single-center series of living renal donors, to describe an evaluation algorithm for AIs in this patient population, and to compare the complication rates of hand-assisted laparoscopic donor nephrectomy (HALDN) with those of combined HALDN and adrenalectomy. METHODS We performed a single-center, retrospective study of consecutive living kidney donors who underwent laparoscopic nephrectomy for transplantation, with or without simultaneous ipsilateral adrenalectomy, between January 2008 and September 2014. RESULTS During the study period, AIs were detected in 18 of 1033 potential living renal donors who underwent computerized tomographic angiography. Application of additional donor selection criteria and of an adrenal mass assessment algorithm resulted in 849 HALDN, of which 13 were combined with simultaneous adrenalectomy. The hospital length of stay (2.4 vs 2.6 days), perioperative (0.025 vs 0.077), early (0.073 vs 0.077), and late (0.014 vs 0.077) postoperative complication rates, and conversion to open donor nephrectomy (0.008 vs 0.00) were not significantly different. Mean operative time was significantly longer in the adrenalectomy group. None of the adrenal masses were malignant. CONCLUSION Here, we presented our algorithm to manage the living kidney donors with AIs. Although donor population with AIs was relatively small in number, simultaneous adrenalectomy and ipsilateral nephrectomy seemed to be technically safe and conferred no identifiable increased risk of malignancy for the kidney transplant donor, when the incidentaloma is nonfunctional and less than or equal to 4 cm as assessed by preoperative imaging.

Abstract
An increased number of adrenal tumors are now diagnosed due to the increased number of abdominal CT scans being performed. We present the first case of malignant lymphoma combined with clinically “silent” pheochromocytoma in the same adrenal gland. An abdominal CT scan demonstrates unilateral adrenal lesion which suggests pheochromocytoma or adrenal carcinoma. Laboratory examinations revealed a slight increase of 24-h urine vanillylmandelic acid and 24-h urinary methanephrine excretion. Histological examination revealed two intermingled tumor cell proliferations—diffuse B cell lymphoma and pheochromocytoma. Unexpected coexistence of catecholamine-producing tumor with the other adrenal lesion can lead to serious complications of diagnosis and treatment. The adequate preparation for surgery can protect patient from threatening catecholamine crisis.

Abstract
Adrenal incidentalomas (AIs) are mostly benign and nonsecretory. Management algorithms lack sensitivity when assessing malignant potential, although functional status is easier to assess. We present a subject whose AI was a retroperitoneal leiomyosarcoma (RL). Case Presentation. A woman on warfarin with SLE and the antiphospholipid syndrome, presented with left loin pain. She was normotensive and clinically normal. Ultrasound scans demonstrated left kidney scarring, but CT scans revealed an AI. MRI scans later confirmed the AI without significant fat and no interval growth. Cortisol after 1 mg dexamethasone, urinary free cortisol and catecholamines, plasma aldosterone renin ratio, and 17-hydroxyprogesterone were within the reference range. Initially, adrenal haemorrhage was diagnosed because of warfarin therapy and the acute presentation. However, she underwent adrenalectomy because of interval growth of the AI. Histology confirmed an RL. The patient received adjuvant radiotherapy. Discussion. Our subject presented with an NSAI. However, we highlight the following: (a) the diagnosis of adrenal haemorrhage in this anticoagulated woman was revised because of interval growth; (b) the tumour, an RL, was relatively small at diagnosis; (c) this subject has survived well over 60 months despite an RL perhaps because of her acute presentation and early diagnosis of a small localised tumour.

Abstract
The finding of an adrenal mass should induce a diagnostic work-up aimed at assessing autonomous hormone production and differentiating between benign and (potentially) malignant lesions. The common differential diagnosis in adrenal incidentaloma consists of (non-)functioning adenoma, pheochromocytoma, myelolipoma, metastasis, and primary carcinoma. There remains a category of lesions that are hormonally inactive and display nonspecific imaging characteristics. We provide a succinct literature review regarding pathologies from this category. Imaging and histological characteristics are discussed, as well as clinical management. In conclusion, an adrenal mass may present a diagnostic challenge. After exclusion of most common diagnoses, it can be difficult to differentiate between possible pathologies based on preoperative diagnostic tests. Surgical resection of possibly harmful tumors is indicated, for example, lesions with malignant potential or risk of spontaneous hemorrhage. Resection of an obviously benign lesion is not necessary, unless problems due to tumor size are expected.

Abstract
BACKGROUND Although adrenal incidentalomas (AI) are detected in ≤5% of patients undergoing chest and abdominal computed tomography (CT), their management is challenging. The current guidelines include recommendations from the National Institutes of Health, the American Association of Endocrine Surgeons (AAES), and the American Association for Cancer Education (AACE). The aim of this study was to develop a new risk stratification model and compare its performance against the existing guidelines for managing AI. METHODS A risk stratification model was designed by assigning points for adrenal size (1, 2, or 3 points for tumors <4, 4-6, or >6 cm, respectively) and Hounsfield unit (HU) density on noncontrast CT (1, 2, or 3 points for HU <10, 10-20, or >20, respectively). This model was applied retrospectively to 157 patients with AI managed in an endocrine surgery clinic to assign a score to each tumor. The utility of this model versus the AAES/AACE guidelines was assessed. RESULTS Of the 157 patients, 54 (34%), had tumors <4 cm with HU <10 (a score of 2). One third of these were hormonally active on biochemical workup and underwent adrenalectomy. The remaining two thirds were nonsecretory lesions and have been followed conservatively with annual testing. In 103 patients (66%), the adrenal mass was >4 cm and/or had indeterminate features on noncontrast CT (HU >10, irregular borders, heterogeneity), and adrenalectomy was performed after hormonal evaluation was completed (10 were hormonally active on biochemical testing). Seven of these patients (7%) had adrenocortical cancer on final pathology with tumor size <4 cm in 0, 4-6 cm in 1, and >6 cm in 5 patients. Of the hormonally inactive patients, 32% had a score of 3, 38% 4, and 30% 5 or 6. The incidence of adrenocortical cancer in these subgroups was 0, 0, and 25%, respectively. CONCLUSION This study shows that an algorithm that utilizes the hormonal activity at the first decision step followed by a consolidated risk stratification, based on tumor size and HU density, has a potential to spare a substantial number of patients from unnecessary "diagnostic" surgery for AI.

Abstract
Background To confirm the efficacy of preoperative workup, the authors analyse the results of a multicentre study in a surgical series of patients diagnosed with an adrenal incidentaloma. Methods The retrospective review of a prospectively collected database was conducted. The data was obtained by six surgical units operating in the Campania Region, Italy. Five-hundred and six (506) adrenalectomies performed between 1993 and 2011 on 498 patients were analysed. Final histology in patients with a preoperative diagnosis of incidentaloma and studied according to guidelines (230/282 patients group A) was compared with final histology coming from patients presenting the same preoperative diagnosis but studied not according to guidelines (52/282 patients group B). Results In group A preoperative diagnosis was confirmed at final histology in 76/81 (93.8%) cases of subclinical functioning lesions presenting as an incidentaloma. The preoperative detection of pheochromocytoma and primary adrenocortical cancer (ACC) reached 91.6% and 84.6% respectively. In group B conversion rate to open surgery was higher than in group A (p = 0.02). One pheochromocytoma was missed at preoperative diagnosis whereas one ACC smaller than 4 centimetres (cm) and coming from an incidental lesion was discovered. In both groups a significant association between increasing dimensions of incidentaloma and cancer has been observed (p = 0.001). Conclusions This surgical series confirm the high efficacy of suggested guidelines. A significant preoperative detection rate of adrenal lesions presenting as incidentaloma is observed. The unnecessary number of adrenalectomies performed in understudied patients, causing higher morbidity, was not associated to a higher detection rate of primary adrenocortical cancer.

Abstract
Laparoscopic procedures are preferred by surgeons and patients alike because of decreased pain, reduced perioperative morbidity, and an earlier return to self-reliance. During the last decade, laparoscopic adrenalectomy has become the technique most commonly used for the removal of benign adrenal tumors. The indications for laparoscopy in malignant adrenal tumors remains controversial, because oncologic resections have not been reproducible compared with open techniques.

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.
