Abstract
BACKGROUND Pheochromocytoma is a rare but severe disease of the adrenal glands. The aim of this study is to present and discuss recent developments in the diagnosis and treatment of pheochromocytoma. MATERIAL AND METHODS A narrative review article based on the most recent literature is presented. RESULTS AND DISCUSSION The proportion of pheochromocytomas as tumors of adrenal origin is about 5% of incidentally discovered adrenal tumors. The classical symptomatic triad of headaches, sweating, and palpitations occurs in only about 20% of patients, while almost all patients show at least 1 of these symptoms. To diagnose pheochromocytoma, levels of free plasma metanephrines or alternatively, fractionated metanephrines in a 24‑h urine collection is required in a first step. In the second step an imaging procedure, computed tomography (CT) or magnetic resonance imaging (MRI), is performed to localize the adrenal tumor. Functional imaging is also recommended to preoperatively detect potential metastases. Genetic testing should always be offered during the course of treatment as 30-40% of pheochromocytomas are associated with genetic mutations. The dogma of preoperative alpha blockade is increasingly being questioned and has been controversially discussed in recent years. Minimally invasive removal of the adrenal tumor is the standard surgical procedure to cure patients with pheochromocytoma. The transabdominal and retroperitoneal laparoscopic approaches are considered equivalent. The choice of the minimally invasive procedure depends on the expertise and experience of the surgeon and should be tailored accordingly. Individualized and regular follow-up care is important after surgery.

Abstract
OBJECTIVE To assess the feasibility of spectral CT-derived extracellular volume (ECV) for differentiating aldosterone-producing nodules (APN) from nonfunctioning adrenal nodules (NFN). METHODS Sixty-nine patients with biochemically and histologically confirmed unilateral APN (34) and NFN (35) as well as 23 patients with bilateral APN (19) and NFN (27) confirmed biochemically and by adrenal vein sampling (AVS) were enrolled in this retrospective study from October 2020 to April 2022. All patients underwent contrast-enhanced spectral CT of the adrenal glands with a 10-min delayed phase. The haematocrit level was measured within 2 days of CT. An iodine density map was derived from the delayed CT. The ECV fractions of the APN and NFN were calculated and compared in the test cohort of 69 patients with unilateral adrenal nodules. The optimal cut-off value was determined to evaluate the diagnostic efficacy of the ECV fraction for differentiating APN from NFN in the validation cohort of 23 patients with bilateral adrenal nodules. RESULTS The ECV fractions of the APN (11.17 ± 4.57%) were significantly lower (p < 0.001) than that of the NFN (24.79 ± 6.01%) in the test cohort. At cut-off ECV value of 17.16%, the optimal area under the receiver operating characteristic curve was 0.974 (95% confidence interval: 0.942-1) with 91.4% sensitivity, 93.9% specificity, and 92.8% accuracy in the test cohort and 89.5% sensitivity, 96.3% specificity, and 93.5% accuracy in the validation cohort for differentiating APN from NFN. CONCLUSION The spectral CT-derived ECV fraction can differentiate APN from NFN with high diagnostic performance. CLINICAL RELEVANCE STATEMENT Spectral CT-derived extracellular volume fraction could accurately differentiate between adrenal aldosterone-producing nodules and nonfunctioning nodules. It might serve as a noninvasive alternative to adrenal vein sampling in primary aldosteronism patients with bilateral adrenal nodules. KEY POINTS • Conventional CT cannot differentiate aldosterone-producing adrenal nodules from nonfunctioning nodules. • Extracellular volume of adrenal aldosterone-producing nodules was significantly lower than that of nonfunctioning nodules and normal adrenal glands. It can accurately differentiate between aldosterone-producing and nonfunctioning adrenal nodules. • Extracellular volume may be a novel, noninvasive biomarker alternative to adrenal vein sampling for determining the functional status of bilateral adrenal nodules in patients with primary aldosteronism.

Abstract
Neuroblastoma is the most common extracranial solid tumor in children, often manifests in the retroperitoneal region. We present a case of a 3-year-old boy with no previous medical history, presented for abdominal distension. Physical examination revealed a distinct, mobile, solid mass situated in the left lumbar region. Abdominal magnetic resonance imaging displayed a well delimited, well-encapsulated mass attached to the tail of the pancreas. Urinary catecholamine metabolite levels were negative. Surgical exploration revealed that the tumor was primitively related to the left adrenal gland, and a complete resection was performed. The postoperative recovery was uncomplicated. NMYC oncogene was non-amplified.

Abstract
INTRODUCTION Once mostly discovered on autopsy, adrenal myelolipomas are now increasingly diagnosed due to the frequent use of modern imaging methods. However, bilaterality remains quite rare. We present the case of a 31 years old female patient treated in our department for a bilateral adrenal myelolipoma which revealed an unknown peripheral adrenal insufficiency. CASE PRESENTATION We describe the case of a 31-year-old woman in apparent good health with no medical history who was explored for recurrent right lumbar pain by a computed tomography scanner which showed a large right adrenal mass and a smaller lesion in the left adrenal gland. Preoperative biology revealed an unknown peripheral adrenal insufficiency. Right open sub-costal adrenalectomy was performed, Histological examination confirmed the diagnosis of bilateral adrenal myelolipomas and radiological surveillance was planned for the left tumor. DISCUSSION Adrenal myelolipoma (AML) is a rare, benign and typically non-functional tumor of the adrenal gland, usually unilateral and asymptomatic, incidentally detected on CT. Commonly diagnosed between the fifth and seventh decades of life. It can affect both sexes our patient is a 31-year-old female and presented with bilateral AML. Unlike previous reported cases, our patient has a previously unknown peripheral adrenal insufficiency, which could be incriminated in the development of his bilateral adrenal myelolipomas. The optimal management depends on both clinical presentation and tumor characteristics. CONCLUSION Adrenal myelolipoma is a rare tumor. Endocrinological investigation should be performed to detect and treat endocrine disorders. The therapeutic attitude depends on tumor size complications and clinical complaints. METHODS This is a case report from our urology department, and has been reported in line with the SCARE criteria.

Abstract
Objective To assess the diagnostic accuracy of histogram analysis on unenhanced computed tomography (CT) for differentiating between adrenal adenomas and pheochromocytomas (PCCs). Materials and Methods We retrospectively identified patients with proven PCCs who had undergone CT examinations between January 2009 and July 2019 at one of two institutions. For each PCC, we selected one or two adenomas diagnosed within two weeks of the date of diagnosis of the PCC. For each lesion, two readers scored the size, determined the mean attenuation, and generated a voxel histogram. The 10th percentile (P10) was obtained from the conventional histogram analysis, as well as being calculated with the following formula: P10 = mean attenuation - (1.282 × standard deviation). The mean attenuation threshold, histogram analysis (observed) P10, and calculated P10 (calcP10) were compared in terms of their diagnostic accuracy. Results We included 52 adenomas and 29 PCCs. The sensitivity, specificity, and accuracy of the mean attenuation threshold were 75.0%, 100.0%, and 82.5%, respectively, for reader 1, whereas they were 71.5%, 100.0%, and 81.5%, respectively, for reader 2. The sensitivity, specificity, and accuracy of the observed P10 and calcP10 were equal for both readers: 90.4%, 96.5%, and 92.6%, respectively, for reader 1; and 92.3%, 93.1%, and 92.6%, respectively, for reader 2. The increase in sensitivity was significant for both readers (p = 0.009 and p = 0.005, respectively). Conclusion For differentiating between adenomas and PCCs, the histogram analysis (observed P10 and calcP10) appears to outperform the mean attenuation threshold as a diagnostic criterion.

Abstract
PURPOSE Adrenal incidentalomas are common lesions found on abdominal imaging, most of which are lipid-rich adrenal adenomas. Imaging diagnoses differentiating lipid-poor adrenal adenomas (LPA) from non-adenomas (NA) are presently challenging to perform. The aim of the study was to investigate the diagnostic performance of the relative enhancement ratio parameter in identifying LPA from NA. METHODS We retrospectively evaluated consecutively presenting patients with lipid-poor adrenal lesions (January 2015 to August 2021). Lesions were divided into LPA and NA (including hyperenhancing and hypoenhancing NA). Kruskal-Wallis and Bonferroni tests were used to determine the differences in feature parameters between these three groups. Receiver operating characteristic curve analysis was performed to determine the sensitivity for diagnosing LPA and NA at 95% specificity; the parameters were compared using the McNemar test. RESULTS A total of 253 patients (mean age, 55 ± 12 years; 135 men), 121 with LPA and 132 with NA, were analyzed herein. The sensitivity (achieved at 95% specificity) of the relative enhancement ratio was higher than that of unenhanced attenuation in differentiating LPA from NA (60% vs. 52%, p = 0.064). The relative enhancement ratio yielded a higher sensitivity than unenhanced attenuation (79% vs. 59%, p < 0.001) in differentiating LPA from hypoenhancing NA, and a lower sensitivity (26% vs. 69%, p < 0.001) in differentiating LPA from hyperenhancing NA. CONCLUSION The relative enhancement ratio showed better diagnostic performance than unenhanced attenuation in differentiating LPA from hypoenhancing NA, while simultaneously showing poor diagnostic performance in identifying LPA from all NA.

Abstract
Contrary to traumatic and iatrogenic intraabdominal hemorrhages, spontaneous intraabdominal hemorrhage is a challenging clinical situation. A variety of neoplastic and non-neoplastic conditions may cause spontaneous intraabdominal bleeding. Imaging findings vary depending on the source of bleeding and the underlying cause. In this article, we aim to increase the awareness of imagers to the most common causes of spontaneous intraabdominal hemorrhage by using representative cases.

Abstract
PURPOSE To assess whether heterogeneous adrenal adenomas can be distinguished from heterogeneous non-adenomas with Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI). METHOD From 2009 to 2019, 980 consecutive adrenalectomies were retrospectively identified. Patients without adequate CT/MRI, with homogeneous and/or < 1 cm lesions were excluded. Differences between adenomas and non-adenomas were analyzed using Chi-square, Student t or Fischer tests, and interobserver agreement using weighted kappa test or intraclass correlation coefficient. Independent variables associated with adenomas were searched for using multivariable analysis. Area under the receiver operating characteristic curve (AUC) of the final model and its diagnostic performances were calculated. RESULTS Final population comprised 183 patients (106 women, 77 men, mean age 53.2 ± 14.4 years) with 124 non-adenomas and 59 heterogeneous adenomas. Macroscopic or microscopic fat on CT/MRI allowed diagnosis of adenoma with 98% specificity and 63% sensitivity. Interobserver agreement was almost perfect for macroscopic fat (k = 0.82; 95% CI 0.66; 0.94) and substantial for microscopic fat (k = 0.75; 95% CI 0.62; 0.86). A multivariable model including micro- or macroscopic fat [Odds ratio (OR) 81.19; 95% CI 20.17; 572.27], diameter < 5.5 cm (OR 7.32; 95% CI 2.17; 31.28), calcifications (OR 5.68; 95% CI 2.08; 16.18), and hemorrhage (OR 3.10; 95% CI 0.70; 15.35) had an AUC of 0.91 (95% CI 0.86; 0.96), 71% (42/59, 95% CI 58; 82) sensitivity, 93% (115/124; 95% CI 87; 97) specificity, and 86% (157/183; 95% CI 79; 90) accuracy for the diagnosis of adenoma. CONCLUSION A multivariable model enables CT/MR diagnosis of heterogeneous adenomas. Presence of microscopic fat, even if partial, in a heterogeneous mass is highly specific of adenoma.

Abstract
OBJECTIVES To investigate whether adrenal volumetry provides better agreement with adrenal vein sampling (AVS) than conventional CT for subtyping PA. Furthermore, we evaluated whether the size of this contralateral adrenal was a prognostic factor for clinical outcome after unilateral adrenalectomy. METHODS We retrospectively analyzed volumes of both adrenal glands of the 180 CT-scans (88/180 with unilateral and 92/180 with bilateral disease) of the patients with PA included in the SPARTACUS trial of which 85 also had undergone an AVS. In addition, we examined CT-scans of 20 healthy individuals to compare adrenal volumes with published normal values. RESULTS Adrenal volume was higher for the left than the right adrenal (mean and SD: 6.49 ± 2.77 ml versus 5.25 ± 1.87 ml for the right adrenal; p < 0.001). Concordance between volumetry and AVS in subtyping was 58.8%, versus 51.8% between conventional CT results and AVS (p = NS). The volumes of the contralateral adrenals in the patients with unilateral disease (right 4.78 ± 1.37 ml; left 6.00 ± 2.73 ml) were higher than those of healthy controls reported in the literature (right 3.62 ± 1.23 ml p < 0.001; left 4.84 ± 1.67 ml p = 0.02). In a multivariable analysis the contralateral volume was not associated with biochemical or clinical success, nor with the defined daily doses of antihypertensive agents at 1 year follow-up. CONCLUSIONS Volumetry of the adrenal glands is not superior to current assessment of adrenal size by CT for subtyping patients with PA. Furthermore, in patients with unilateral disease the size of the contralateral adrenal is enlarged but its size is not associated with outcome.

Abstract
OBJECTIVE To compare MR-imaging features in benign lipid-rich and lipid-poor adrenal adenomas. MATERIALS AND METHODS With institutional review board approval, we compared 23 consecutive lipid-poor adenomas (chemical shift [CS] signal intensity [SI] index < 16.5%) imaged with MRI to 29 consecutive lipid-rich adenomas (CS-SI index ≥ 16.5%) imaged during the same time period. A blinded radiologist measured T2-weighted (T2W) SI ratio (adrenal adenoma/psoas muscle), dynamic enhancement wash-in (WI) and wash-out (WO) indices, and T2W texture features. Two blinded Radiologists (R1/R2) assessed T2W-SI (relative to renal cortex) and T2W heterogeneity (using 5-Point Likert scales). Comparisons were performed between groups using independent t tests and Chi-square with Holm-Bonferroni correction. RESULTS There was no difference in age or gender between groups (p = 0.594, 0.051 respectively). Subjectively, all lipid-rich and lipid-poor adenomas were rated hypointense or isointense compared to renal cortex and T2W-SI did not differ between groups (p = 0.129, 0.124 for R1, R2). Agreement was substantial (Kappa = 0.67). There was no difference in T2W SI ratio (1.8 ± 0.9 [0.5-4.3] lipid rich versus 2.2 ± 1.0 [0.6-4.3] lipid poor, p = 0.139). Enhancement WI and WO did not differ comparing lipid-rich and lipid-poor adenomas (p = 0.759, 0.422 respectively). There was no difference comparing lipid-rich and lipid-poor adenomas T2W heterogeneity judged subjectively (p = 0.695, 0.139 for R1, R2; Kappa = 0.19) or by texture analysis (entropy, kurtosis, skewness; p = 0.134-0.191) with all adenomas except for one rated as mostly or completely homogeneous. CONCLUSIONS There is no difference in T2W signal intensity, enhancement pattern or T2W heterogeneity judged subjectively or by quantitative texture analysis comparing lipid-poor and lipid-rich adrenal adenomas.

Abstract
A 57-year-old male patient was referred to our department with complaints of his right adrenal gland occupancy and hypertension about 6 months. When admitted to the hospital, the blood pressure was about 160/100 mmHg, and the heart rate was 110 beats/min. He was no obvious obesity, acne, abnormal mood, without weakness of limbs, acral numbness, palpitation and headache. He presented with type 2 diabetes for more than 3 years, with oral administration of metformin enteric coated tablets and subcutaneous injection of insulin glargine to control blood glucose, and satisfied with blood glucose control. Enhanced CT showed that: the right adrenal gland showed a kind of oval isodense, slightly hypodense shadow, the edge was clear, lobular change, the size was about 5.8 cm×5.4 cm, uneven density, there were nodular and strip calcification, round lipid containing area and strip low density area, and the CT value of solid part was about 34 HU. Enhanced scan showed heterogeneous nodular enhancement in the solid part of the right adrenal gland, nodular enhancement could be seen inside. The CT values of solid part in arterial phase, venous phase and delayed phase were 45 HU, 50 HU and 81 HU, respectively. Considering from the right adrenal gland, cortical cancer was more likely. No obvious abnormality was found in his endocrine examination. After adequate preoperative preparation, retroperitoneal laparoscopic adrenalectomy was performed under general anesthesia. During the operation, the 6 cm adrenal tumor was closely related to the inferior vena cava and liver, and after careful separation, the tumor was completely removed and normal adrenal tissue was preserved. The operation lasted 180 min and the blood loss was 100 mL, and the blood pressure was stable during and after the operation. There was no obvious complication. The results of pathological examinations were as follows: the size of the tumor was 7.5 cm×6.0 cm×3.5 cm, soft, with intact capsule and grayish-red cystic in section. Pathological diagnosis: (right adrenal gland) cavernous hemangioma, secondary intravascular thrombosis, old hemorrhagic infarction with calcification and ossification. After 6 months of observation, no obvious complications and tumor recurrence were found. In summary, cavernous hemangioma of adrenal gland is a rare histopathological change. Its essence is a malformed vascular mass. Blood retention is the cause of thrombosis and calcification in malformed vessels. The imaging findings were inhomogeneous enhancement of soft tissue masses, and the adrenal function examination showed no obvious abnormalities. Retroperitoneal laparoscopic surgery is feasible after adequate preoperative preparation. It is difficult to diagnose the disease preoperatively and needs to be confirmed by postoperative pathology.

Abstract
Purpose We reviewed the experience with adrenal ganglioneuroma (AGN) pathologically confirmed following adrenalectomy in medium- to high-volume medical centers. Methods The medical records of all adrenalectomy cases in 4 medical centers between 2006 and 2020 were retrospectively reviewed for demographics, clinical, radiological and laboratory findings, surgical treatment, pathology results, and outcomes. Results Twenty-five out of 875 adrenalectomy cases (2.9%) were pathologically confirmed as AGN. Those patients' average age was 40.5 years (range, 4-76 years), 13 (52.0%) were males, and 18 lesions (72.0%) were right-sided. One patient had a family history of neurofibromatosis, and another had a succinate dehydrogenase gene mutation. Abdominal/back pain attributed to mass effect was the most common symptom. All 25 patients underwent abdominal computerized tomography scanning in which the average maximal tumor diameter was 6.61 cm. The mean pre- and postcontrast Hounsfield units (HU) values were 35.2 and 59, respectively; and the mean late-phase HU value was 71.1. Twenty-two patients (88.0%) underwent minimally invasive surgery. The average tumor diameter recorded in the final pathology report was 7 cm. Isolated AGN was diagnosed in 21 cases (84.0%), and the additional components reported for the remaining 4 cases included pheochromocytoma (2), ganglioneuroblastoma (1), and neurofibroma (1). The average follow-up length was 16.8 months (range, 1-136 months), during which there was no recurrence or death. Conclusion AGN is a rare, slow-growing, large benign tumor with radiological characteristics similar to those seen in malignant tumor. Final diagnosis is established by pathology after surgical resection, preferably minimally invasive, with an overall excellent prognosis.

Abstract
Thermal ablation is a good alternative treatment in patients who are unable to undergo adrenalectomy. Even though the Asian Conference on Tumor Ablation (ACTA) has been held for many years, adrenal ablation guidelines have not been established. No guidelines for adrenal ablation are established in American and European countries, either. The aim of this review was to introduce the first version of ACTA guidelines for adrenal tumor ablation.

Abstract
Since the introduction of minimally invasive surgery, laparoscopic adrenalectomy has become the main treatment option for adrenal masses. Various studies have reported that laparoscopic adrenalectomy showed fewer postoperative complications and faster recovery than conventional open adrenalectomy. Laparoscopic adrenalectomy can be performed through either the transperitoneal approach or the retroperitoneoscopic approach, which are widely used in most adrenal surgical procedures. Furthermore, with the development of minimally invasive surgery, organ-sparing adrenalectomy has recently emerged as a way to conserve functional adrenal gland tissue. According to recent data, organ-sparing adrenalectomy shows promising surgical, functional, and oncological outcomes including less intraoperative blood loss, maintenance of adrenal function, and low recurrence. Partial adrenalectomy was initially proposed for bilateral adrenal tumors in patients with hereditary disease to avoid chronic adrenal insufficiency. However, it has also gained popularity for the treatment of unilateral adrenal disease involving a small adrenal tumor because even patients with a unilateral adrenal gland may develop adrenal insufficiency in stressful situations. Therefore, partial adrenalectomy has become increasingly common to avoid lifelong steroid replacement and recurrence in most cases, especially in bilateral adrenal disease. This review article evaluates the current evidence on minimally invasive adrenalectomy and organ-preserving partial adrenalectomy.

Abstract
Image-guided radiofrequency ablation (RFA) has been accepted as a minimally invasive treatment for adrenal tumors in patients who are unable to undergo adrenalectomy. Accordingly, this treatment has become more readily available for treating functioning or non-functioning adrenal masses. Thus, endocrinologists need a better understanding of percutaneous RFA of adrenal tumors. The purpose of this review is to briefly describe the basic mechanism of RFA, indications and contraindications, patient preparation prior to RFA, type of complications, how to avoid complications, RFA procedures, and treatment outcomes.

Abstract
Objective: To analyze and summarize the clinical characteristics of primary aldosteronism (PA) with concurrent adrenal Cushing's syndrome (ACS). Methods: The clinical, imaging and pathological data of 87 patients with PA admitted to Peking University First Hospital from January 1st, 2013 to December 31th, 2016 were reviewed. There were 45 males (51.7%) and 42 females (48.3%) with an average age of (52.7±10.5) years (range: 15-70 years). According to whether they were diagnosed with ACS, the patients were divided into PA with concurrent ACS group (n=11) and pure PA group (n=55). The clinical characteristics of PA with concurrent ACS were summarized. Results: Ten of the eleven patients in PA with concurrent ACS group were diagnosed with subclinical ACS. Compared with these in pure PA group, the patients in PA with concurrent ACS group were older [(55.6±9.1) years vs (48.4±10.2) years, P=0.033], with larger diameters of adrenal tumors [(2.3±1.6) cm vs (1.4±0.6) cm, P=0.015], higher serum cortisol levels in the circadian rhythm [158 (92, 217) nmol/L vs 71 (43, 128) nmol/L at 0∶00, P=0.004], lower plasma adrenocorticotropic hormone (ACTH) levels in the circadian rhythm [0.80 (<0.22, 1.45) pmol/L vs 4.40 (2.58, 5.93) pmol/L at 8∶00, P<0.001; 0.25 (<0.22, 0.91) pmol/L vs 2.03 (0.74, 3.69) pmol/L at 16∶00, P<0.001;<0.22 (<0.22, 0.44) pmol/L vs 1.27 (<0.22, 2.66) pmol/L at 0∶00, P<0.001], and higher serum cortisol levels after 1 mg overnight dexamethasone suppression test [95 (73, 142) nmol/L vs 30 (22, 41) nmol/L, P<0.001]. Unilateral adrenalectomy was performed in 31 patients, of whom 3 patients in PA with concurrent ACS group (3/8) and 3 patients in pure PA group (3/23) presented with adrenal insufficiency and received glucocorticoid replacement therapy after adrenalectomy. Conclusions: PA with concurrent ACS is not rare in PA patients, which are mainly complicated with subclinical ACS and easily misdiagnosed. It is recommended that elderly PA patients with large adrenal tumors should be screened for ACS by means of cortisol and ACTH circadian rhythm and 1 mg overnight dexamethasone suppression test. Postoperative adrenal insufficiency is prone to occur in those patients, who should be followed up closely after adrenalectomy, and receive glucocorticoid replacement therapy in time.

Abstract
Objective To investigate the advantages of using modified signal intensity measurements on chemical shift imaging alone or in conjunction with proton magnetic resonance spectroscopy in the differential diagnosis of adrenal adenomas. Materials and Methods This was a prospective study involving 97 patients with adrenal nodules or masses. The signal intensity index (SII) was calculated as [(signal intensity on the in-phase image − signal intensity on the out-of-phase image) ∕ (signal intensity on the in-phase image)] × 100%. We determined the averages of the minimum, mean, and maximum signal intensity values measured on three consecutive images. When that was not possible (for smaller lesions), we used one or two images. We employed a region of interest that covered one half to two thirds of the mass. All indices were compared with metabolite ratios derived from spectroscopy: lactate/creatine; glutamine-glutamate/creatine; choline/creatine; choline/lipid; 4.0-4.3 ppm/Cr; and lipid/creatine. Results Of the 97 patients evaluated, 69 were diagnosed with adenomas and 28 were diagnosed with nonadenomas. All SII measurements and spectroscopy-derived metabolite ratios were significant to the differentiation between adenomas and nonadenomas, except for the lipid/creatine and choline/lipid ratios. In 37.8% of the cases, it was not possible to perform spectroscopy. When it was possible, the lactate/creatine ratio was found to have higher accuracy than did the SII. Conclusion Determining the SII and metabolite ratios increased the accuracy of the differential diagnosis of adrenal adenomas.

Abstract
Adrenal masses are mainly detected unexpectedly by an imaging study performed for reasons unrelated to any suspect of adrenal diseases. Such masses are commonly defined as "adrenal incidentalomas" and represent a public health challenge because they are increasingly recognized in current medical practice. Management of adrenal incidentalomas is currently matter of debate. Although there is consensus on the need of a multidisciplinary expert team evaluation and surgical approach in patients with significant hormonal excess and/or radiological findings suspicious of malignancy demonstrated at the diagnosis or during follow-up, the inconsistency between official guidelines and the consequent diffuse uncertainty on management of small adrenal incidentalomas still represents a considerable problem in terms of clinical choices in real practice. The aim of the present work is to review the proposed strategies on how to manage patients with adrenal incidentalomas that are not candidates to immediate surgery. The recent European Society of Endocrinology/European Network for the Study of Adrenal Tumors guidelines have supported the view to avoid surveillance in patients with clear benign adrenal lesions <4 cm and/or without any hormonal secretion; however, newer prospective studies are needed to confirm safety of this strategy, in particular in younger patients.

Abstract
Except when caused by direct and definite mechanisms (e.g., injury of the vessels to the femoral head), the pathophysiology of avascular necrosis of the femoral head has not yet been fully elucidate. While non-traumatic avascular necrosis of the femoral head is known to be caused by alcohol, steroids and various diseases, it may also occur without such events in a patient's history. Herein, a case of bilateral avascular necrosis of the femoral head caused by asymptomatic adrenal cortex incidentaloma which was initially misdiagnosed as idiopathic is reported along with a literature review.

Abstract
OBJECTIVE To determine all-cause mortality risk in patients with and without adrenal incidentaloma. METHODS Retrospective cohort study of patients with CT abdomen performed within 24 h of emergency room presentation at an academic medical center from January 1, 2005, to December 31, 2009, without history of adrenal disease, adrenal lab testing, or cancer. Incidentaloma cohort identified by database query of imaging reports followed by manual review and matched to no-nodule controls at 3:1 on age ± 1 year and exam date ± 3 months. Mortality ascertained by in-hospital deaths and National Death Index query. Survival analysis performed with Kaplan-Meier curves and Cox proportional hazards models. RESULTS Among 42,575 adults with abdominal CT exams, 969 adrenal incidentaloma patients and 2907 no-nodule controls were identified. All 3876 individuals entered survival analysis with 31,182 person-years at risk (median follow-up 8.9 years [IQR, 6.9-10.7]). All-cause mortality was significantly higher among those with adrenal incidentalomas (353/969, 36.4%) compared with those without (919/2907, 31.6%; mortality difference 7.6 per 1000 person-years; multivariable-adjusted hazard ratio [aHR] 1.14; 95% CI, 1.003-1.29). Exploratory analyses, limited by missing covariates, found that adrenal incidentalomas were associated with significantly increased incidence of malignancy (aHR 1.61; 95% CI, 1.22-2.12), diabetes (aHR 1.43; 95% CI, 1.18-1.71), heart failure (aHR 1.32; 95% CI, 1.07-1.63), peripheral vascular disease (aHR 1.28; 95% CI, 1.95-1.56), renal disease (aHR 1.21; 95% CI, 1.01-1.44), and chronic pulmonary disease (aHR 1.22; 95% CI, 1.01-1.46) compared with controls. CONCLUSIONS Adrenal incidentalomas are associated with increased mortality and may represent a clinically valuable biomarker. KEY POINTS • Adrenal incidentalomas are associated with increased mortality. • Adrenal incidentaloma size is not predictive of mortality. • On exploratory analyses, adrenal incidentalomas are associated with chronic illnesses.

Abstract
PURPOSE The aim was to determine the optimal slice thickness of CT images and the optimal threshold of negative voxels for CT histogram analysis to distinguish adrenal adenomas from non-adenomas with a mean attenuation more than 10 Hounsfield units (HU). METHODS Volume CT histogram analysis of 83 lipid-poor adenomas and 80 non-adenomas was performed retrospectively. The volume of interest was extracted from each adrenal lesion, and the mean attenuation, standard deviation (SD), and percentage of voxels with a negative CT value were recorded using reconstructions with different slice thicknesses (5 mm, 2.5 mm, 1.25 mm). The percentage of negative voxels was correlated with SD as a measure of image noise and with the reference splenic tissue values. The sensitivity, specificity, and positive predictive value (PPV) for the identification of adenomas were calculated using reconstructions with different slice thicknesses and three different thresholds of negative voxels (1%, 5%, 10%). RESULTS The percentage of negative voxels increased with a thinner slice thickness and correlated with increasing CT image noise in adenomas, non-adenomas, and spleen. Using a threshold of 10% negative voxels and a slice thickness of 5 mm, we reached a sensitivity of 53.0%, specificity of 98.8% and the highest PPV, and thus we propose this combination for clinical use. Other combinations achieved a clearly lower specificity and PPV as a result of the increasing noise in CT images. CONCLUSION The CT slice thickness significantly affects the result and diagnostic value of histogram analysis. Thin CT slice reconstructions are inappropriate for histogram analysis.

Abstract
BACKGROUND Adrenocortical carcinoma (ACC) is a rare endocrine cancer with treatments limited in efficacy for metastatic disease. New molecular targeted therapies have yet to improve patient outcomes. In contrast, established treatment regimens of adrenolytics and chemotherapy have demonstrated treatment benefit, although admittedly in a minority of patients. Identification of microRNAs (miRNAs) in patients responsive to adjuvant therapy may offer a means to sensitize patients with progressive disease to existing adjuvant regimens. MATERIALS AND METHODS Samples from primary ACC tumors of 10 Stage IV patients were examined for differentially expressed miRNAs between a "sensitive" and "resistant" cohort. Candidate microRNAs were restored via transfection in two functional ACC cell lines. Gain of function and effects on apoptosis and cell cycle were assessed. RESULTS microRNA-431 (miR-431) was underexpressed in patients with ACC with progressive disease undergoing adjuvant therapy. Restoration of miR-431 in vitro decreased the half maximal inhibitory concentrations of doxorubicin and mitotane, with markedly increased apoptosis. We found that a reversal of epithelial-mesenchymal transition underlies the action of miR-431 with doxorubicin treatment, with Zinc Finger E-Box Binding Homeobox 1 implicated as the molecular target of miR-431 in ACC. CONCLUSION This is the first report of the potential of miRNA therapy to sensitize ACC to current established adjuvant therapy regimens, which may mitigate the resistance underlying treatment failure in patients with advanced ACC. Effective and well-studied methods of targeted miRNA delivery in existence hints at the imminent translatability of these findings. IMPLICATIONS FOR PRACTICE Adrenocortical carcinoma (ACC) is a rare endocrine cancer with outcomes not improving despite extensive research and new targeted therapies. Mitotane and etoposide/doxorubicin/cisplatin chemotherapy is trial validated for improved recurrence-free survival. However, a minority of patients experience sustained benefit. Significant side effects exist for this regimen, with patients often unable to attain target drug doses shown to give survival benefit. This preclinical study examines the role of microRNAs in sensitizing ACC to doxorubicin or mitotane. This study offers an important bridge between new and existing cancer treatments, offering an imminently translatable approach to the treatment of adrenocortical carcinoma.

Abstract
Patients with Beckwith-Wiedemann syndrome (BWS) are predisposed to developing embryonal tumors, with hepatoblastoma being the most common type. Our patient showed hemihypertrophy, macroglossia, and paternal uniparental disomy in chromosome 11 and was diagnosed with BWS. When the patient was 9 months old, a 2.5×1.5 cm oval hypoechoic exophytic mass was detected in the inferior tip of his right liver. Preoperative imaging identified it as hepatoblastoma; however, histologic, immunohistochemistry, and electron microscopic findings were compatible with adrenal cortical neoplasm with uncertain malignant potential. The origin of the adrenal tissue seemed to be heterotopic. Here, we describe for the first time an adrenal cortical neoplasm with uncertain malignant potential arising in the heterotopic adrenal cortex located in the liver of a patient with BWS.

Abstract
PURPOSE Large adrenal masses pose a diagnostic dilemma. The purpose of this study was twofold: first, to assess the degree of interobserver agreement in evaluating the morphology of pathologically proven adrenal adenomas and adrenocortical carcinomas larger than 4 cm in diameter; and second, to identify morphologic characteristics that correlated with the pathologic diagnosis. MATERIALS AND METHODS For this blinded, retrospective study, we collected cases of 25 adrenal adenomas and 33 adrenocortical carcinomas measuring larger than 4 cm. Two radiologists evaluated morphologic characteristics of the lesions on CT. Interobserver agreement was evaluated using kappa statistics, and the correlation of imaging characteristics with the diagnosis was evaluated using a logistic regression model. RESULTS We found the highest interobserver agreement in the assessment of precontrast attenuation (Κ = 0.81) as well as substantial agreement in determining the shape and the presence of calcifications (Κ = 0.69 and 0.74, respectively). Readers agreed less often regarding the presence of fat (Κ = 0.48), as well as regarding the presence of necrosis, heterogeneity, and the overall impression (Κ = 0.15, 0.24, and 0.26, respectively). CT characteristics correlated with benignity included round shape (p = 0.02), an overall radiologic impression of a benign lesion (p < 0.0001), the presence of fat (p = 0.01), and a precontrast attenuation of less than 10 Hounsfield units (p < 0.0001). The latter two of these characteristics were highly specific for benign pathology (93% and 100%, respectively). CONCLUSION Our study suggests that CT has the ability to consistently identify characteristics significantly correlated with benign vs. malignant adrenal tumors.

Abstract
Background Multiple endocrine neoplasia type 1 (MEN1) is a rare, autosomal dominant inherited syndrome caused by mutations in the MEN1 tumor suppressor gene. The diagnosis is defined clinically by the presence of 2 or more primary MEN1 tumors (parathyroid, anterior pituitary, and pancreatic islet). We describe the case of a patient who presented with classic history and imaging findings for MEN1. Case Report A male in his early thirties with a history of hyperparathyroidism and a transsphenoidal prolactinoma resection presented years later with abdominal symptoms concerning for Zollinger-Ellison syndrome: worsening epigastric abdominal pain, nausea, vomiting, and diarrhea. Contrast-enhanced computed tomography (CT) of the abdomen revealed hyperenhancing pancreatic lesions and duodenal inflammation, suggesting pancreatic neuroendocrine tumor (gastrinoma) with secondary duodenitis. Bilateral indeterminate hypoattenuating adrenal nodules were also seen on contrast-enhanced CT, and follow-up magnetic resonance imaging confirmed benign adrenal adenomas. Furthermore, thyroid ultrasound and sestamibi scintigraphy revealed a parathyroid adenoma. With confirmatory imaging findings, history, and presenting symptoms, the patient was clinically diagnosed with MEN1 syndrome and underwent surgical and medical management. Conclusion This case exhibits the classic history with corresponding imaging findings of MEN1 syndrome, including pancreatic neuroendocrine tumors, parathyroid adenoma, and adrenal adenomas. High clinical suspicion for MEN1 should lead to endocrinology evaluation with appropriate laboratory workup and targeted imaging evaluation of the typical endocrine organs as described for this patient.

Abstract
Objectives This study aims to define a radiomic signature for pre-operative differentiation between subclinical pheochromocytoma (sPHEO) and lipid-poor adrenal adenoma (LPA) in adrenal incidentaloma. The goal was to apply a predictive, preventive, and personalized medical approach to the management of adrenal tumors. Patients and methods This retrospective study consisted of 265 consecutive patients (training cohort, 212 (LPA, 145; sPHEO, 67); validation cohort, 53 (LPA, 36; sPHEO, 17)). Computed tomography (CT) imaging features were evaluated, including long diameter (LD), short diameter (SD), pre-enhanced CT value (CTpre), enhanced CT value (CTpost), shape, homogeneity, necrosis or cystic degeneration (N/C). Radiomic features were extracted and then were used to construct a radiomic signature (Rad-score) and radiomic nomogram. The area under the receiver operating characteristic curve (AUC) was used to evaluate their performance. Results Sixteen of three hundred forty candidate features were used to build a radiomic signature. The signature was significantly different between the sPHEO and LPA groups (AUC: training, 0.907; validation, 0.902). The radiomic nomogram based on enhanced CT features (M1) consisted of Rad-score, LD, SD, CTpre, shape, homogeneity and N/C (AUC: training, 0.957; validation, 0.967). The pre-enhanced CT features based radiomic nomogram (M2) included Rad-score, LD, SD, CTpre, shape, and homogeneity (AUC: training, 0.955; validation, 0.958). Conclusions Our radiomic nomograms based on pre-enhanced and enhanced CT images distinguished sPHEO from LPA. In addition, the promising result using pre-enhanced CT images for predictive diagnostics is important because patients could avoid the additional radiation and risk associated with enhanced CT.

Abstract
OBJECTIVES To perform a systematic review and meta-analysis of published data to evaluate the utility of chemical shift imaging (CSI) for differentiating between adrenal adenomas and non-adenomas. METHODS A systematic search of the MEDLINE, Web of Science Core Collection, EMBASE and Cochrane Central Register of Controlled Trials electronic databases was performed. The methodological quality of the included studies was assessed by using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies) tool. A bivariate random effect model was used to determine summary and subgroup sensitivity and specificity and calculate summary receiver operating characteristic curves (SROC). RESULTS Eighteen studies with 1138 patients and 1280 lesions (859 adenomas, 421 non-adenomas) in total were included. In addition to summary analysis, quantitative analyses of the adrenal signal intensity index (SII, 978 lesions, 14 studies), adrenal-to-spleen ratio (ASR; 394 lesions, 7 studies) and visual analysis (560 lesions, 5 studies) were performed. The resultant data showed considerable heterogeneity (inconsistency index I2 of 94%, based on the diagnostic odds ratio, DOR). The pooled sensitivity of CSI for adenoma was 0.94 [95% confidence interval (CI) 0.88-0.97] and pooled specificity was 0.95 (95% CI 0.89-0.97). The area (AUC) under the SROC curve was 0.98 (95% CI 0.96-0.99). The corresponding AUCs were 0.98, 0.99 and 0.95 for SII, ASR and visual evaluation, respectively. CONCLUSION CSI has high sensitivity, specificity and accuracy for adrenal adenoma. Diagnostic performance does not improve when quantitative indices are used. KEY POINTS • Inclusion of CSI in abdominal MRI protocols provides an effective solution for classifying adrenal masses discovered on MR exams • Visual evaluation of adrenal CSI is sufficient; use of quantitative indices does not improve diagnostic accuracy.

Abstract
Objective: To study the clinicopathologic characteristics, immunophenotype, pathologic diagnosis and differential diagnosis of myxoid adrenocortical adenomas. Methods: The clinical data, histological features and immunohistochemical results of 4 cases of myxoid adrenocortical adenomas were analyzed, which were collected from January 2014 to December 2016 at Guangdong General Hospital, with review of literature. Results: Four cases of myxoid adrenocortical adenomas were presented. The patients ages ranged from 26 to 45 years (mean =35 years). Microscopically, it showed a typical morphology, characterized by small-sized tumor cell cords or pseudo-glands embedded in an abundant extracellular myxoid matrix. Immunohistochemical staining showed tumor cells were strongly positive for Melan A, vimentin and focally for α-inhibin, one case showed strong and diffuse positivity for CAM5.2, and two cases showed diffuse positivity for synaptophysin, while negative for CgA, S-100 protein, epithelial antigen, CK7, CK20 and CKpan. Conclusions: Myxoid adrenocortical adenomas are extremely rare, which may cause confusion with metastatic well-differentiated neuroendocrine tumours, sex cord-stromal tumoursor metanephric adenoma. Recognition of this entity would be beneficial for pathologists to avoid misdiagnosis, and unnecessary treatment.

Abstract
Background Ewing sarcoma/primitive neuroectodermal tumor is a family of highly malignant proliferation of neuroectodermal origin, most often skeletal, adrenal localization is extremely rare. Only few cases have been reported in the literature. Classical management includes radical surgery with adjuvant chemotherapy or radiotherapy or both. This case report is the only one where recurrence was surgically removed, and it confirms the importance of adjuvant treatment, and the efficacy of neoadjuvant chemotherapy. Case presentation We report the case of a 23-year-old Moroccan woman presenting with flank pain. An abdominal computed tomography scan showed a large and enhancing left suprarenal mass. After radical nephrectomy, histologic examination revealed a small round cell proliferation. The diagnosis of Ewing sarcoma was confirmed by molecular analysis; time to final diagnosis was 5 months due to financial and coordination issues. Computed tomography (on an asymptomatic patient) revealed a locoregional recurrence, our patient received 12 cycles of the vincristine, doxorubicin and cyclophosphamide/ifosfamide and etoposide protocol used in an alternating schedule, with partial radiologic response (62%) and pathologic complete response, then underwent adjuvant radiotherapy of 45 Gy. The young women is still in remission after 36 months of follow-up. Conclusions Our patient had an early recurrence due to absence of adjuvant treatment, but did respond well to neoadjuvant chemotherapy with a pathologic complete response. Management of adrenal Ewing sarcoma could be extrapolated from skeletal one with good outcomes even in locoregional recurrence.

Abstract
Objective: To review and discuss the experience of diagnosis and treatment of adrenal ganglioneuroma. Methods: Clinical data of 80 cases of adrenal ganglioneuroma undergoing surgery during January 1982 to May 2017 at Peking Union Medical College Hospital were retrospectively analyzed. There were 36 male and 44 female patients. Age ranged from 8 to 69 years old (mean 37.7 years old). The tumor diameter were 1.5 to 18.0 cm (mean 4.3 cm). There were 61 cases of adrenal ganglioneuroma diagnosed by imaging examination. All patients underwent adrenalectomy. Results: All procedures were performed successfully without serious complication. Including 15 open surgery and 64 retroperitoneal laparoscopic surgery. One laparoscopic case conversion to open surgery. The pathological diagnosis was adrenal ganglioneuroma. Fifteen cases were mixed with other tumor components. No recurrence or metastasis was observed during the follow-up of 2 months to 35 years. Conclusions: The diagnostic techniques for adrenal ganglioneuroma are helpful to judge the tumor property before operation. The laparoscopic surgery has become the current method for resecting tumors. It shows advantages of small trauma and speedy recovery. The relationship between tumor and surrounding tissues should be understand clearly before operation. Full preparation must be made before operation if adrenal ganglioneuroma mixed with other tumor components.

Abstract
Objective: To evaluate the efficacy of 24 h urinary free cortisol (24 h UFC) in the diagnosis of subclinical Cushing's syndrome (SCS), and explore the best diagnostic cut-off value. Methods: The clinical data of patients with adrenal incidentaloma in Chinese PLA General Hospital between January 2008 and December 2016 was retrospectively reviewed and analyzed. All SCS patients were diagnosed based on the current Cushing's syndrome (CS) guidelines and confirmed by histopathology and then treated as study group, and additional patients with non-functional adrenal adenoma (NFA) were enrolled as control group. ROC curve was used to evaluate efficacy of 24 h UFC and 24 h UFC to creatinine ratio (UFCCR), and explore their best cut-off values. Results: There were 161 patients with NFA, of which contained 84 males and 77 females, with a mean age of (51.02±10.49) years old. There were 88 patients with SCS, of which contained 26 males and 62 females, with a mean age of (51.74±10.29) years old. The 24 h UFC and UFCCR levels were significant higher in SCS group than those in NFA group[510 (363, 698) nmol vs 335 (209, 467) nmol for 24 h UFC, and 7.82(4.79, 12.13) ml vs 4.82(2.41, 6.57)ml for UFCCR, both P<0.05]. ROC analysis showed that the optimal cut-off for 24 h UFC was 480 nmol (AUC 0.716, 95% CI: 0.648-0.784, with a sensitivity of 58.0% and a specificity of 79.4%) and the optimal cut-off for UFCCR was 6.84 ml (AUC 0.729, 95% CI: 0.662-0.796, with a sensitivity of 59.1% and a specificity of 78.7%). Conclusions: The recommended cut-off points of 24 h UFC and UFCCR for diagnosing SCS in AI patients were 480 nmol and 6.84 ml, respectively.

Abstract
Objective: To determine the effect of the surgical and conservative approaches on the metabolic profiles in patients with subclinical Cushing's syndrome (SCS) in adrenal incidentalomas (AI). Methods: A hundred and thirty AI patients with SCS in Department of Endocrinology, PLA General Hospital between January 2008 and December 2016 were studied, surgery was performed in 88 patients (surgical group), and the rest received conservative approach (conservative group). The improvement/worsening of blood pressure, blood glucose, lipid profiles and body weight after a duration of >18 months follow-up were analyzed, respectively. Results: Baseline demographics, clinical characteristics were similar between surgical and conservative groups. In the surgical group, blood pressure, blood glucose, lipid profiles and body weight improved more frequently than that in conservative group (29.69% vs 3.12%, P=0.003; 10.94% vs 3.12%, P=0.262; 7.81% vs 3.12%, P=0.660; 39.06% vs 9.38%, P=0.004, respectively). In conservative group, blood pressure, blood glucose, lipid profiles and body weight worsened more frequently than that in surgical group (28.13% vs 0, P<0.001; 25.0% vs 0, P<0.001; 18.75% vs 0, P=0.003; 40.62% vs 20.31%, P=0.051, respectively). Logistic regression analysis indicated surgical treatment was associated with improvement of blood pressure (OR=10.687, 95%CI: 1.279-89.299) and weight loss (OR=5.541, 95%CI: 1.404-21.872) independently of gender, age, duration of follow-up, serum cortisol level after 1 mg-dexamethasone suppression test and the mass size. Conclusion: In AI patients with SCS, surgery was beneficial in the aspect of metabolic profiles.

Abstract
Extracorporeal membrane oxygenation has been extensively used for cardiopulmonary support in cardiogenic shock. However, its clinical value in the management of pheochromocytoma crisis remains unclear. We report a rare case of life-threatening cardiogenic shock managed with peripheral venoarterial extracorporeal membrane oxygenation combined with endovascular left ventricular venting, in a 40-year-old female patient, in the setting of unknown adrenal pheochromocytoma. We highlight the life-saving role of extracorporeal membrane oxygenation in undiagnosed endocrine emergencies, allowing cardiac and end-organ recovery, and giving time for accurate diagnosis and specific treatment in such unusual situations.

Abstract
Objective To describe a modified approach to the evaluation of adrenal nodules using a
standard abdominal magnetic resonance imaging protocol. Materials and Methods Our sample comprised 149 subjects (collectively presenting with 132 adenomas
and 40 nonadenomas). The adrenal signal intensity index was calculated.
Lesions were grouped by pattern of enhancement (PE), according to the phase
during which the wash-in peaked: arterial phase (type 1 PE); portal venous
phase (type 2 PE); and interstitial phase (type 3 PE). The relative and
absolute wash-out values were calculated. To test for mean differences
between adenomas and nonadenomas, Student's t-tests were
used. Receiver operating characteristic curve analysis was also
performed. Results The mean adrenal signal intensity index was significantly higher for the
adenomas than for the nonadenomas (p < 0.0001). Chemical
shift imaging showed a sensitivity and specificity of 94.4% and 100%,
respectively, for differentiating adenomas from nonadenomas. Of the
adenomas, 47.6%, 48.5%, and 3.9%, respectively, exhibited type 1, 2, and 3
PEs. For the mean wash-in proportions, significant differences were found
among the enhancement patterns. The wash-out calculations revealed a trend
toward better lesion differentiation for lesions exhibiting a type 1 PE,
showing a sensitivity and specificity of 71.4% and 80.0%, respectively, when
the absolute values were referenced, as well as for lesions exhibiting a
type 2 PE, showing a sensitivity and specificity of 68.0% and 100%,
respectively, when the relative values were referenced. The calculated
probability of a lipid-poor lesion that exhibited a type 3 PE being a
nonadenoma was > 99%. Conclusion Subgrouping dynamic enhancement patterns yields high diagnostic accuracy in
differentiating adenomas from nonadenomas.

Abstract
Non-secreting pheochromocytomas are rare adrenal tumours. We report the case of a clinically and biochemically silent giant pheochromocytoma that presented as bilateral pulmonary embolisms. Successful surgical resection was performed. Multiple endocrine neoplasia 2 syndrome and neurofibromatosis type 1 were clinically excluded. Subsequent DNA analysis of the succinate dehydrogenase complex subunits B and D (SDHB and SDHD), and Von Hippel-Lindau (VHL) genes revealed no mutations.

Abstract
The authors report the case of a 63-year-old man who underwent an open adrenalectomy for a synchronous, malignant, metastatic left adrenal tumor and a total colectomy for T3N0M1 (stage 4) primary, malignant colon cancer. Two polypoid lesions, one measuring 40 mm × 30 mm × 30 mm and the other measuring 20 mm × 10 mm × 10 mm, were found in the ascending colon and rectosigmoid (RS) junction, respectively, and a synchronous, malignant, left adrenal gland lesion measuring 70 mm × 50 mm × 30 mm was incidentally found on abdominal computed tomography scan. Histological examination revealed a metastatic, necrotic adenocarcinoma of the left adrenal mass, an adenocarcinoma of the cecal mass, and an adenomatous polyp (tubulovillous type) of the smallest polypoid lesion in RS junction that had invaded deeply into the submucosal layer. The patient recovered uneventfully, and his condition is now stable, with no evidence of local recurrence or metastatic disease, 2 years after the surgery. To the best of our knowledge, only 25 cases of an adrenalectomy for treating metastatic adrenal gland tumors have been reported to date; physicians should be aware of the possibility of this event.

Abstract
Ewing's sarcoma, also called primitive neuroectodermal tumour of the adrenal gland, is extremely rare. Only a few cases have been reported in the literature. We report on a woman with adult-onset primitive neuroectodermal tumour of the adrenal gland presenting with progressive flank pain. Computed tomography confirmed an adrenal tumour with invasion of the left diaphragm and kidney. Radical surgery was performed and the pain completely resolved; histology confirmed the presence of primitive neuroectodermal tumour, for which she was given chemotherapy. The clinical presentation of this condition is non-specific, and a definitive diagnosis is based on a combination of histology, as well as immunohistochemical and cytogenic analysis. According to the literature, these tumours demonstrate rapid growth and aggressive behaviour but there are no well-established guidelines or treatment strategies. Nevertheless, surgery remains the mainstay of local disease control; curative surgery can be performed in most patients. Adjuvant chemoirradiation has been advocated yet no consensus is available. The prognosis of patients with primitive neuroectodermal tumours remains poor.

Abstract
We report the case of a 25-year-old woman with tetralogy of Fallot who presented with chest pain and hypertension, and on further investigation, was diagnosed with a pheochromocytoma in the right adrenal gland. She underwent surgical excision of the tumor. While the simultaneous occurrence of these two diseases is extremely rare, the suspicion of a possible relationship has been raised in the past.

Abstract
BACKGROUND Adrenal gland involvement is a very rare extranodal presentation of sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease). Its pathogenesis still remains unknown with many theories about its probable cause. Symptoms and signs of adrenal involvement presentation are uncertain. Although, it is a disease with a good prognosis and a favorable clinical course in most cases, the low index of suspicion and difficulty in radiological differential diagnosis lead to radical treatment. CLINICAL CASE We present a case of Rosai-Dorfman disease with right adrenal plus left infrahiliar nodal involvement. It was treated with adrenalectomy and node exeresis. The infrahilial involvement evolution was appropriate. CONCLUSIONS Rosai-Dorfman disease is a rare disease and the extra-nodal presentation is even more rare. The incidence and evolution of this disease in the adrenal gland is unknown. The presence of this pathology should be considered if the patient shows adrenal gland affected and lymph node growth, in order to consider the individualized treatment, which may vary (treatment with corticosteroids, chemotherapy and/or radiotherapy).

Abstract
A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was 'in [patients with isolated adrenal metastasis from operable/operated non-small cell lung cancer] is [adrenalectomy] superior [to chemo/radiotherapy alone for achieving long-term survival]?' Altogether >160 papers were found using the reported search, of which 3 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We conclude that the body of evidence is small, retrospective and not formally controlled. As such interpretation is limited by selection bias in assignment of patients. These limitations notwithstanding, surgical resection is associated with prolonged survival for patients with isolated adrenal metastasis from non-small cell lung cancer (NSCLC). Patient selection is probably critical. Factors that are important are: otherwise early tumour, node (TN) status of the lung primary and R0 resection, long disease-free interval and confidence that there are no other sites of metastasis. Patients with ipsilateral adrenal metastasis may derive the greatest survival benefit from adrenalectomy, since spread to the ipsilateral gland may occur via direct lymphatic channels in the retroperitoneum. Involvement of the contralateral adrenal may signify haematogenous spread and therefore, a more aggressive process. Adrenalectomy must be accompanied by regional lymph node clearance to reduce the chance of further spread from the adrenal itself.

Abstract
BACKGROUND/AIMS We investigated the clinical characteristics and follow-up findings of subjects with adrenal incidentalomas in a single, tertiary-care hospital in South Korea. METHODS The study consisted of a retrospective analysis of 282 adrenal incidentaloma patients who underwent radiographic and endocrinological evaluations at Samsung Medical Center in Seoul, South Korea, between January 2004 and July 2011. RESULTS Most (86.2%) of the subjects were found to have nonfunctioning tumors. Functioning tumors were seen in 39 patients (13.8%). Among them, 28 (9.9%) had subclinical Cushing syndrome (SCS), six (2.1%) had pheochromocytoma, and five (1.8%) had primary hyperaldosteronism. Malignant adrenal tumors were discovered in three cases: two (0.7%) were primary adrenal cancers, and one (0.4%) was a secondary metastasis from a lung cancer. Significant risk factors for functional tumors were female gender (odds ratio [OR], 3.386; 95% confidence interval [CI], 1.611 to 7.117; p = 0.0013) and a noncontrast attenuation value of > 10 Hounsfield units (OR, 2.806; 95% CI, 1.231 to 6.397; p = 0.0141). During follow-up (mean, 22.5 months) of 72 of the patients, three (4.2%) developed hormonal changes due to functional tumors. One was confirmed as pheochromocytoma by histopathology, and the others were diagnosed with SCS and followed routinely without surgical intervention. No malignant transformation was found in these patients. CONCLUSIONS Based on these findings, initial hormonal and radiographic evaluations for adrenal incidentalomas appear to be more important than follow-up tests because functional or malignant changes are rare.

Abstract
An adult with unoperated tetralogy of Fallot diagnosed simultaneously with pheochromocytoma is extremely rare. This poses obvious diagnostic and therapeutic challenges. A 29-year-old woman with these conditions was successfully operated on for both diseases in the same hospitalization. There is some interesting speculation regarding the association of pheochromocytoma with uncorrected cyanotic congenital heart disease.

Abstract
Context: Present knowledge about intraoperative management, morbidity, and mortality of patients with undiagnosed catecholamine-producing tumors is mostly based on published case reports and anecdotal evidence. Aims: The aim was to summarize the management and outcomes of reported cases and analyze for practice patterns, deduct useful management recommendations as applicable. Settings and Design: The Medline database was searched with specific keywords for the period of 1988-2010 for cases of incidental pheochromocytomas and paragangliomas. Materials and Methods: Case reports in the English language with a postoperative diagnosis of pheochromocytoma and paraganglioma by histopathology were included. Systematic data extraction from case reports was done. Statistical analysis used: Descriptive statistics were applied. Results: Of 823 retrieved records, 62 case reports met inclusion criteria. Hemodynamic instability occurred primarily during mass manipulation/intraoperatively (52%, n = 32) and induction/laryngoscopy (18%, n = 11). In cases reporting specific antihypertensive treatments, nitrates (67%, n = 30) represented the majority of medications used, followed by beta-blockers (47%, n = 21). Alpha receptor blockers were administered in 33% (n = 15). The perioperative mortality was 8% (n = 5), and none of these patients received intraoperative alpha blockade. A catecholamine-secreting tumor was suspected intraoperatively in 26% of cases. Conclusions: The perioperative mortality based on the reviewed cases of incidental catecholamine producing tumors was less than would traditionally be expected. Intraoperative alpha receptor blockade to treat hypertension was reported in 33% of cases, and none of the patients with a fatal outcome had received it. A higher intraoperative index of suspicion and a lower threshold to consider alpha blocking medications for severe intraoperative hypertension may improve outcomes.

Abstract
Oncocytoma is a neoplasm consisting of oncocytes that is found in the salivary gland, kidney, and thyroid. Adrenocortical oncocytoma is particularly uncommon, and most cases reported are benign and nonfunctioning. Here, we report a 20 cm adrenal mass associated with necrosis that was identified as an oncocytic adrenocortical tumor with uncertain malignant potential through histopathological evaluation after its resection.

Abstract
Purpose The prognosis of patients with malignant pheochromocytoma is poor, but the predictive factors are not well understood. We aimed to identify the clinical characteristics predictive of malignancy after initial surgical removal in patients with pheochromocytoma. Materials and Methods We retrospectively reviewed the records of 152 patients diagnosed with pheochromocytoma, including 5 (3.3%) with metastasis at the time of the initial surgical excision and 12 (7.9%) who developed metastasis during follow-up. To determine the factors predictive of malignancy, we compared clinical, radiographical, and urinary chemical findings between patients with benign and malignant disease. Mean follow-up was 41.5 months (range, 0.9-298 months) after surgery. Results Malignant tumors were significantly larger than benign tumors (11.1±4.0 cm vs. 6.2±3.4 cm, p<0.001), and postoperative persistence of arterial hypertension was more frequent after removal of malignant than benign tumors (p=0.001). Among the 147 patients without metastatic disease at diagnosis, those who developed metastasis had significantly lower concentrations of urinary catecholamine metabolites per unit of tumor, including vanillylmandelic acid (1.2 vs. 3.7 mg/day/cm, p=0.049), epinephrine (4.5 vs. 168.9 µg/day/cm, p=0.008), and norepinephrine (13.1 vs. 121.8 mg/day/cm, p<0.001). The overall 5-year metastasis-free survival rate was 84.4% and was significantly higher in patients with smaller tumors (≤5.5 vs. >5.5 cm; 90.6% vs. 81.2%, p=0.025) and higher 24-hour secretion of vanillylmandelic acid (>2.1 vs. ≤2.1 mg/day/cm; 94.9% vs. 70.9%, p=0.019). Conclusions Large tumor size (>5.5 cm) and minimally elevated 24-hour urinary vanillylmandelic acid (≤2.1 mg/day/cm) were significantly associated with a higher probability of a malignant pheochromocytoma portending a lower metastasis-free survival and mandating more rigorous follow-up after surgery.
