Abstract
OBJECTIVE Due to increased use of computed tomography (CT), prevalence of thyroid and adrenal incidentalomas is rising. Yet, previous studies on the outcomes of diagnostic work-up of incidentalomas are subjected to inclusion bias. Therefore, we aimed to investigate prevalence and outcomes of diagnostic work-up of thyroid and adrenal incidentalomas detected on chest CT in a less selected population of COVID-19 suspected patients. DESIGN A retrospective, observational cohort study. METHODS We included all COVID-19 suspected patients who underwent chest CT between March 2020 and March 2021. Radiology reports and medical records were reviewed for the presence and subsequent diagnostic work-up of thyroid and adrenal incidentalomas. RESULTS A total of 1,992 consecutive COVID-19 patients were included (59.4% male, median age 71 years [IQR: 71-80]). Thyroid and adrenal incidentalomas were identified in 95 (4.8%) and 133 (6.7%) patients, respectively. Higher prevalence was observed with increasing age, among female patients and in patients with malignancy. Forty-four incidentalomas were further analyzed, but no malignancies were found. Only three lesions were hormonally active (1 thyrotoxicosis and 2 mild autonomous cortisol secretion). Diagnostic work-up did not lead to any change in clinical management in 97.7% of the analyzed patients. CONCLUSION Prevalence rates of thyroid and adrenal incidentalomas on chest CT in a less selected COVID-19 cohort were 4.8% and 6.7%, respectively. Yet, as all incidentalomas turned out to be benign and only three lesions were (mildly) hormonally active, this raises the question whether intensive diagnostic work-up of incidentalomas is necessary in all patients.

Abstract
Since the inception of fluorine-18 fluorodeoxyglucose (F-18 FDG), positron emission tomography/computed tomography (PET/CT) utilizing F-18 FDG has become widely accepted as a valuable imaging modality in the field of oncology, with global prevalence in clinical practice. Given that a single Torso PET/CT scan encompasses the anatomical region from the skull base to the upper thigh, the detection of incidental abnormal focal hypermetabolism in areas of limited clinical interest is both feasible and not uncommon. Numerous investigations have been undertaken to delineate the distinctive features of these findings, yet the outcomes have proven inconclusive. The incongruent results of these studies present a challenge for physicians, leaving them uncertain about the appropriate course of action. This article provides a succinct overview of the characteristics of fluorodeoxyglucose, followed by a comprehensive discussion of the imaging findings and clinical significance associated with incidental focal abnormal F-18 FDG activity in several representative organs. In conclusion, while the prevalence of unrecognized malignancy varies across organs, malignancies account for a substantial proportion, ranging from approximately one-third to over half, of incidental focal uptake. In light of these rates, physicians are urged to exercise vigilance in not disregarding unexpected uptake, facilitating more assured clinical decisions, and advocating for further active evaluation.

Abstract
PURPOSE The purpose of this study was to assess the type and prevalence of stroke and non-stroke-related findings diagnosed on early cardiac computed tomography (CT) in patients with suspected stroke. The secondary objective was to assess the clinical consequences on the management of patients with non-stroke-related conditions identified by early cardiac CT. MATERIALS AND METHODS This single-center, retrospective, observational study included 1111 consecutive patients with suspected ischemic stroke between November 2018 and March 2020 who underwent cardiac CT examination in addition to the usual brain CT protocol (i.e., non-enhanced brain CT, perfusion brain CT when needed, aortic arch and supra-aortic CT angiography, and post contrast brain CT). There were 562 women and 549 men with a median age of 74 years (range: 60-85 years). Of these, 415 (415/1111; 37.4%) patients had ischemic stroke and 692 (692/1111; 62.3%) had no stroke. Cardiac CT examinations were retrospectively reviewed for cardiac CT findings at high embolic risk and clinically significant extracardiac incidental findings. RESULTS Among 1111 included patients, 89 (89/1111; 8.0%) had a stroke-related condition identified on early cardiac CT. This was significantly more frequent in patients with ischemic stroke (66/415; 15.9%) by comparison with those without ischemic stroke (23/696; 3.3%) (P < 0.001), with 41 patients (41/415; 9.9%) diagnosed with left atrial thrombus. Cardiac CT revealed a clinically significant non-stroke-related finding in 173 patients (173/1111; 15.6%), including 17 pulmonary embolisms (1.5%), seven suspicious pulmonary lesions (0.6%), and three breast lesions suspected to be malignant (0.3%). Twenty out of 173 patients (20/173; 11.5%) with incidental findings on early cardiac CT had a change in their management. CONCLUSION This study shows that adding early cardiac CT to brain CT during the acute phase of an ischemic stroke leads to a higher rate of etiological diagnoses and highlights the major interest of looking at the bigger picture.

Abstract
PURPOSE The uncertainty on the management of small adrenal incidentalomas (AIs) still represents a challenge in real clinical practice. Considering the lack of knowledge on risk factors implicated in tumour enlargement, the aim of this study was to identify risk factors for morphological changes during follow-up of adrenal incidentalomas (AIs). METHODS We retrospectively evaluated demographic, clinical, radiological and biochemical parameters of 153 AIs (2007-2021). Patients with histological diagnosis of metastases or pheochromocytoma were excluded. To detect risk factors for tumor enlargement, diseases associated with AIs were included if their prevalence was higher than 2%. Patients were divided into two groups (A: radiological stability; B: tumor enlargement defined as > 5 mm/year in the main diameter). RESULTS Group A: 89.5% and group B: 10.5%, mean follow-up 38.6 ± 6.9 months (range 6-240). Tumor enlargement when occurred was within 36 months of follow-up. In group B high body weight (p < 0.03), dehydroepiandrosterone sulfate (DHEAS) (p < 0.05) and direct renin concentration (DRC) (p < 0.04) were higher than group A, while aldosterone levels were lower; moreover, considering comorbidities, glaucoma and dysglycemia (p < 0.01 for both) had higher prevalence in group B. Glaucoma and dysglycemia were independent predictors of enlargement. Patients affected by glaucoma, atrial fibrillation, dysglycemia had a lower dimensional change-free survival than non-affected. CONCLUSIONS Glaucoma might be a novel risk factor for AI enlargement. If subtle undetectable cortisol hypersecretion has a role is a topic for further research.

Abstract
INTRODUCTION AND IMPORTANCE Adrenal myelolipomas are uncommon benign tumors of the adrenal gland. It has various other sites of origin. CASE PRESENTATION A 51-year-old male with elevated serum creatinine and an incidentally discovered adrenal mass underwent right adrenalectomy for an adrenal myelolipoma, a benign tumor with fat and haematopoietic components after bee string bite. As the patient was experiencing right hypochondrial pain surgery was planned. After surgery, he developed a surgical site infection, which was treated with antibiotics, and his wound healed well. Excision biopsy confirmed the non-malignant nature of the tumor. CLINICAL DISCUSSION Adrenal myelolipomas are often unilateral, non-functional, and diagnosed using imaging (CT/MRI). While radiological findings can be specific, inconclusive cases may require biopsy for confirmation. Surgical intervention is reserved for hormonally active, symptomatic, or rapidly growing myelolipomas, particularly if they exceed 5 cm. CONCLUSION Adrenal myelolipomas are common in adrenal glands, typically diagnosed in midlife with no gender bias. Imaging, especially CT, is effective in detecting fat components. In cases of diagnostic uncertainty, fine needle biopsy is crucial for confirmation, and surgery is considered when tumors are hormonally active, grow substantially, or cause symptoms, highlighting personalized care based on patient and imaging data.

Abstract
By virtue of material differentiation capabilities afforded through dedicated postprocessing algorithms, dual-energy CT (DECT) has been shown to provide benefit in the evaluation of various diseases. In this article, we review the diagnostic use of DECT in the assessment of genitourinary diseases, with emphasis on its role in renal stone characterization, incidental renal and adrenal lesion characterization, retroperitoneal trauma, reduction of radiation, and contrast dose and cost-effectiveness potential. We also discuss future perspectives of the DECT scanning mode, including the use of novel contrast injection strategies and photon-counting detector computed tomography.

Abstract
PURPOSE The optimal management approach for presumed non-functioning pituitary microadenomas (microNFPAs) remains unclear. Our aim was to capture current UK practice and identify changes with time. METHODS Two online surveys investigating clinicians' approaches were performed in 2009-2010 and 2021-2022 (advertised through Society for Endocrinology UK). RESULTS 150 and 214 clinicians participated in the 2021 and 2009 survey, respectively (response rates 31.2% and 35.4%, respectively). At baseline, 2021 survey respondents were more likely to measure IGF-1 (96.0% vs 74.1%, p < 0.001) and morning cortisol (87.9% vs 62.6%, p < 0.001), and less likely GH (26.2% vs 42.6% p = 0.002), 24 h urine free cortisol (3.4% vs 23.2%, p < 0.0001) or dynamically assess adrenal reserve (11.4% vs 30.4%, p < 0.001). 47.2% of clinicians in 2021 would reassess pituitary function annually until discharge (in absence of tumour growth/symptoms). The 2021 survey respondents were more likely to stop imaging at or before 3 years (81.7% vs 44.3%, p < 0.001) and at or before 5 years (86.6.% vs 72.9%, p = 0.002), whilst 2009 survey respondents were more likely to continue imaging beyond 5 years (24% vs 7%, p < 0.001). Responses on imaging frequency/intervals showed notable variability in both surveys. CONCLUSIONS Diagnostic and management approaches for microNFPAs have evolved in the UK. Biochemical investigations are performed in accord with consensus guidelines, though many clinicians perform annual biochemical surveillance without tumour growth/symptoms. A small number of clinicians request imaging beyond 5 years, but the frequency of imaging intervals until discharge remains variable. Robust evidence on the long-term natural history of microNFPAs is necessary to unify clinician approach.

Abstract
PURPOSE To evaluate reasons for performing ultrasonography (US) and completeness of US reports in patients undergoing endocrine consultation with the first diagnosis of nodular disease. METHODS Since January 1 to June 30, 2021, we prospectively collected patient data (age and thyroid-stimulating hormone concentrations), reasons for performing thyroid US, and completeness of reports regarding the description of the thyroid gland and nodules. In the case of multiple nodules, we considered the nodule suspected of malignancy and the largest one. To evaluate the accuracy of thyroid nodule description, we referred to the five characteristics suggested by the ACR TI-RADS system. RESULTS A total of 341 patients with thyroid nodules received endocrine consultation (female, 78%). The most frequent reasons for performing thyroid US were unrelated to a suspected thyroid disease (31.7%), followed by incidentaloma (23.5%), dysfunction or positivity for thyroid antibodies (19.1%), symptomatic or visible nodules (17.6%), and family history of any thyroid disease (8.2%). Gland texture was not reported in 41.9%. The depth of the lobes was the dimension reported most frequently (42.2%), but any diameter was not reported in 57.8% of the cases. As regards the description of the most relevant nodule, length was reported more frequently (75.9%). Margins and echogenicity were more frequently described (54.5% and 44.3%, respectively) than other characteristics (composition: 27%; shape: 8.8%; echogenic foci: 6.7%). No reports had indicated the malignancy risk stratification. CONCLUSIONS The results of the study demonstrate that in patients undergoing endocrine consultation with first detected thyroid nodules, US was mostly performed in asymptomatic cases, US reports were incomplete, and no risk stratification system was reported.

Abstract
PURPOSE We aimed to evaluate the frequency and malignancy rate of incidental salivary gland lesions (ISGLs) in patients undergoing 18F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT). METHODS Using a predefined algorithm, all descriptions of FDG-PET/CT scans performed in the North Denmark Region at the Department of Nuclear Medicine, Aalborg University Hospital from 1.12 2009 to 31.12 2019 were electronically searched for focal uptake in one or more salivary glands. RESULTS In total, 28,362 FDG-PET/CT scans were performed in the study period. ISGLs were found in 197 (0.7%). A total of 193 (98%) had parotid gland ISGL, and four (2%) had submandibular ISGL. No sublingual lesions were found. Ultimately, 117 patients (60%) were referred to the Department of Otorhinolaryngology-Head and Neck Surgery for evaluation. Fine needle aspiration biopsy was performed in 97 patients, and the most frequent cytopathology was Warthin's tumour (n = 62). Two patients had verified malignancy: one with histopathologically proven acinic cell carcinoma and one with cytopathologically proven metastasis from an oral squamous cell carcinoma. CONCLUSIONS Incidental salivary gland findings on FDG-PET/CT are rare, and the risk of malignancy is low. Patients with ISGL may be evaluated secondary to the primary disease, but special attention should be given to patients with prior or known head-and-neck malignancies and patients with symptoms from the salivary glands, including swelling.

Abstract
With the increasing use of abdominal imaging, adrenal masses are more frequently detected. Depending on the clinical context, the detection of an adrenal mass has different consequences for downstream testing and therapy. As adrenal masses comprise various benign and malignant aetiologies, all lesions >1 cm need further diagnostic workup. Evaluation should address radiological features with respect to potential malignancy and endocrine activity of the lesion. The majority of adrenal masses are benign, functionally inactive adenomas that need no further therapy or follow-up. Nonetheless, functional adenomas, pheochromocytomas, metastases, adrenal cancer or others account for a relevant proportion of lesions. To determine an appropriate therapy, suspicious, malignant or hormonally active tumours should be discussed in an interdisciplinary tumour board. In case of surgery of a lesion with concomitant hormonal excess, perioperative management needs to be guided by the specific requirements of this entity to avoid increased morbidity and mortality.

Abstract
Background Incidentalomas, defined as incidental findings on imaging, are a growing concern. Our aim was to determine the impact and outcomes of extrahepatic incidentalomas on liver transplantation.
Methods Patients at a large liver transplant center, who had an initial MRI for hepatocellular carcinoma screening between January 2004 and March 2020 were identified. Clinical data were collected retrospectively. Survival analysis, utilizing Kaplan Meier estimates and Cox proportional hazards regression analysis, was utilized to determine factors associated with liver transplantation. Results 720 patients were included. NASH (24.9%), HCV (22.1%) and alcohol (20.6%) were the most common causes of cirrhosis. 79.7% of patients had an extrahepatic incidentaloma. Older age and having received a liver transplant by the end of the study were associated with an incidentaloma. MELD was not associated with the presence of an incidentaloma. On univariate Cox proportional hazards regression, male sex, history of moderate alcohol use, smoking history, MELD, and incidentalomas were predictors of liver transplantation. On multivariate analysis, only MELD and the presence of an incidentaloma were found to be significant. Discovery of an incidentaloma was associated with a 30% increase in the risk of liver transplantation. Median time to transplantation did not differ based on the presence on an incidentaloma. Patients with cirrhosis from alcohol or HCV had a significantly shorter median time to transplantation than those with NASH. Renal and pancreatic lesions comprised 91% of all incidentalomas. Conclusions In this single-center retrospective study, extrahepatic incidentalomas were common in patients with cirrhosis. The finding of an incidentaloma was associated with a higher risk of liver transplantation despite a similar median time to transplantation if no incidentaloma was discovered.

Abstract
Adrenal incidentalomas are common findings discovered at abdominal CT and MRI, yet the most appropriate management remains controversial and guidelines vary. The Society of Abdominal Radiology (SAR) Disease-Focused Panel on Adrenal Neoplasms sought to determine the practice patterns of abdominal radiologists regarding the interpretation and management of adrenal incidentalomas. An electronic survey consisting of eleven multiple choice questions about adrenal incidentalomas was developed and distributed to the email list of current and past SAR members. The response rate was 11.8% (423/3581) and most respondents were academic radiologists (80.6%). The 2017 American College of Radiology White Paper was the most used guideline, yet the management of indeterminate adrenal incidentalomas was highly variable with no single management option reaching a majority. Hormonal evaluation and endocrinology consultation was most often rarely or never recommended. The results of the survey indicate wide variability in the interpretation of imaging findings and management recommendations for incidental adrenal nodules among surveyed radiologists. Further standardization of adrenal incidentaloma guidelines and education of radiologists is needed.

Abstract
Pituitary adenomas produce a complex collection of disorders. Some are incidental findings. Some distort local anatomical structures which can lead to disorders of vision or hormone production. Some produce excesses of hormones which can be either life threatening or clinically distressing. The management requires the expertise of a variety of experts who plan together. No single treatment is universally successful in controlling these conditions. Medical, biochemical, surgical and radiosurgical management can all have parts to play. Coordinate co-operation between specialists will provide patients with the best available treatment.

Abstract
A radiographic incidental finding (sometimes called an incidentaloma) is defined as a structure that is unintentionally found during an exam for an unrelated indication. The increased use of routine abdominal imaging is associated with a rising incidence in incidentalomas of the kidney 1. In one meta-analysis, 75% of renal incidentalomas were benign 2. However, the overall prevalence of incidental carcinomas is low at 0.2% 3. With the growing uptake of POCUS, healthy volunteers for clinical demonstrations may find themselves with new findings despite a lack of symptoms 4. Having an incidentaloma discovered during the course of a nephrology POCUS workshop is a unique experience. Herein we report our experiences of having incidentalomas discovered during the course of POCUS demonstrations.

Abstract
BACKGROUND As the volume and fidelity of magnetic resonance imaging (MRI) of the brain increase, observation of incidental findings may also increase. We performed a systematic review and meta-analysis to determine the prevalence of various incidental findings. METHODS PubMed/MEDLINE, EMBASE and SCOPUS were searched from inception to May 24, 2021. We identified 6536 citations and included 35 reports of 34 studies, comprising 40,777 participants. A meta-analysis of proportions was performed, and age-stratified estimates for each finding were derived from age-adjusted non-linear models. RESULTS Vascular abnormalities were observed in 423/35,706 participants (9.1/1000 scans, 95%CI 5.2-14.2), ranging from 2/1000 scans (95%CI 0-7) in 1-year-olds to 16/1000 scans (95%CI 1-43) in 80-year-olds. Of these, 204/34,306 were aneurysms (3.1/1000 scans, 95%CI 1-6.3), which ranged from 0/1000 scans (95%CI 0-5) at 1 year of age to 6/1000 scans (95%CI 3-9) at 60 years. Neoplastic abnormalities were observed in 456/39,040 participants (11.9/1000 scans, 95%CI 7.5-17.2), ranging from 0.2/1000 scans (95%CI 0-10) in 1-year-olds to 34/1000 scans (95%CI 12-66) in 80-year-olds. Meningiomas were the most common, in 246/38,076 participants (5.3/1000 scans, 95%CI 2.3-9.5), ranging from 0/1000 scans (95%CI 0-2) in 1-year-olds to 17/1000 scans (95%CI 4-37) in 80-year-olds. Chiari malformations were observed in 109/27,408 participants (3.7/1000 scans, 95%CI 1.8-6.3), pineal cysts in 1176/32,170 (9/1000 scans, 95%CI 1.8-21.4) and arachnoid cysts in 414/36,367 (8.5/1000 scans, 95%CI 5.8-11.8). CONCLUSION Incidental findings are common on brain MRI and may result in substantial resource expenditure and patient anxiety but are often of little clinical significance.

Abstract
Background Different MRI parameters have been studied for evaluating thyroid nodules. Diffusion-weighted imaging (DWI) and T2 imaging sequences with considerable efficacy in evaluating soft tissue tumors merit further assessment for thyroid nodule investigation. Method We evaluated incidental thyroid nodules (ITNs) reported on head and neck MRI studies. The T2 signal intensity (SI), T2 signal intensity ratio (SIR), Z value, and apparent diffusion coefficient (ADC) values of the thyroid nodule were obtained for every patient. The patients were referred to the radiology department for the thyroid nodule ultrasound study. Finally, 33 participants (37 thyroid nodules) who were scheduled for fine needle aspiration and cytology (FNAC) were enrolled. Regarding the FNAC results, the nodules were divided into malignant and benign groups. The two groups’ MRI parameters were compared using a two samples independent t test, and the cutoff values were estimated by analyzing the receiver operating characteristics plot. Results The T2 signal intensities, SIR, Z values, and ADC values were significantly higher in the benign group than malignant. The cutoff points of 230 (AUC = 0.759), 3.38 (AUC = 0.754), 37 (AUC = 0.759), and 1.73 (AUC = .690) were obtained for T2 values, SIR, Z values, and ADC values, respectively. Conclusion T2, SIR, Z, and ADC values are reliable for discriminating benign from malignant ITNs. However, further studies with a larger sample size are needed to provide more accurate mean values, identify outliers, and reduce confounding factors and bias.

Abstract
The bony components of the craniovertebral junction (CVJ) have been investigated in 172 skeletons, dug up from several archaeological sites, to define the frequency of developmental dysmorphisms, and to acquire qualitative and quantitative data about their morphology. A review of the pertinent literature is also presented. Twenty-five individuals (14.5%) exhibited at least one dysmorphism, which ranged from a condition of simple variant to a true malformation. Four individuals presented two or more anomalies at the same time (2.3% of the whole sample, 16% of the affected individuals). The most frequently observed abnormalities were: (i) the presence of a complete bony bridge in the atlas, forming a canal surrounding the vertebral artery (arcuate foramen, supertransverse foramen, and the simultaneous occurrence of arcuate foramen and supertransverse foramen); (ii) the presence of basilar processes. Basilar processes displayed a great variety in shape and dimension. They also differed with respect to their relationship with atlas and axis. The less frequently detected anomalies were: (i) complete absence of the posterior arch of C1, (ii) fusion of C2 and C3, and (iii) irregular segmentation of C2. A broad array of structural defects has been described at the CVJ. They may occur either isolated or as part of complex multisystem syndromes. Although harmless in many cases, they can notwithstanding cause severe, even life-threatening complications. When unrecognized, they may generate trouble during surgery. Hence, accurate knowledge of CVJ arrangement, including its multifarious variations, is a critical issue for radiologists, clinicians, surgeons, and chiropractors.

Abstract
Pituitary incidentalomas are discovered in approximately 10% to 40% of brain images. A complete patient history, physical examination, and dedicated pituitary function testing are needed, and subsequent results should lead to appropriate patient management. However, most lesions are asymptomatic pituitary adenomas or Rathke cleft cysts with a benign course. Many lesions can be clinically significant, including prolactinomas or other pituitary adenomas that warrant specific pituitary disease treatment. In other cases, mass effect causing visual compromise or refractory headache indicates a need for surgery. Here, various facets of a complex evaluation and treatment algorithm for pituitary incidentalomas are reviewed.

Abstract
INTRODUCTION Meta-analysis aimed to quantify the relationship between intraductal papillary mucinous neoplasm (IPMN) and increased incidence of extra-pancreatic malignancy (EPM) previously reported in qualitative observational cohort studies. METHODS Study protocol was registered with PROSPERO (CRD42020169614) and conducted to the Meta-analysis Of Observational Studies in Epidemiology and systematic review reported with Preferred Reporting Items for Systematic Reviews and Meta-Analyses, Assessing the Methodological Quality of Systematic Reviews guidelines. RESULTS Sixteen studies (total of 8240 patients) were included in the pooled, and 7399 patients in the subgroup meta-analyses. The odds ratio (OR) for any EPM in the presence of IPMN was 57.9 (95% confidence interval 40.5-82.7), fixed effects, I2 = 59% (p < 0.0014). Subgroup analysis for any gastrointestinal EPM (i.e. oesophagus, stomach, colon and rectum) in the presence of an IPMN estimated an overall OR of 12.9 (95% confidence interval 8.8-19.0), fixed effects, I2 = 64% (p < 0.0004). CONCLUSION Patients with an IPMN are categorically at increased risk for a higher incidence of EPM and particularly the odds of a gastrointestinal malignancy are also increased in comparison with the general population. We advocate that patients presenting with an IPMN should be considered for gastrointestinal screening including colonoscopy, upper gastrointestinal endoscopy or computed tomography.

Abstract
BACKGROUND Adrenal Cushing's syndrome is characterized by ACTH-independent hypercortisolism. Adrenal vein sampling (AVS) is not routinely employed prior to management decisions, and few studies have investigated the value of AVS in this population. We assessed whether AVS provides a diagnostic benefit for treatment planning. MATERIALS AND METHODS Six patients with imaging and biochemical evidence of adrenal Cushing's syndrome undergoing AVS at our institution from 2015 to 2020 were analyzed retrospectively, including demographic and clinical characteristics. AVS lateralization index was determined by comparing the (cortisol/ipsilateral reference hormone) ratios of both adrenal veins. lateralization index of 2 or greater was considered diagnostic of unilateral disease. Post-management clinical improvement was defined as serum cortisol normalization, symptomatic improvement, or both. RESULTS Cross-sectional imaging noted bilateral adrenal enlargement or nodules in three patients, and unilateral nodules in three patients. AVS results were discordant with imaging in three patients. Treatment included medical management in two patients, percutaneous radiofrequency ablation in one patient, and laparoscopic adrenalectomy in two patients. One patient was lost to follow up. AVS results aided management planning in five patients, definitively changing treatment from surgery to medical management in one patient. All five patients demonstrated clinical improvement. CONCLUSIONS AVS offered useful information for determining appropriate management of adrenal Cushing's syndrome, especially distinguishing unilateral from bilateral disease. Even in bilateral disease, AVS may show a dominant gland, potentially allowing a staged unilateral adrenalectomy, before assessing the need for completion adrenalectomy or medical management. Larger studies are needed to better establish whether AVS offers significant benefit for this population.

Abstract
OBJECTIVE Parotid incidentalomas on fluorodeoxyglucose positron emission tomography/computed tomography imaging are rare. A systematic review was performed to assess their aetiology and association with scanning indication, and to develop an evidence-based algorithm for their management. METHODS A literature search was performed on 25 August 2020 using the keywords 'incidentaloma', 'incidental finding', 'parotid', 'parotid gland', 'salivary gland' and 'head and neck'. Articles were reviewed by two authors before their inclusion. RESULTS Forty articles were included, totalling 558 incidentalomas. The mean incidence was 0.74 per cent. Lung cancer was the most common imaging indication. The most common aetiologies were cystadenolymphoma, pleomorphic salivary adenoma and metastases. Only cystadenolymphoma (p = 0.015) and pleomorphic salivary adenoma (p = 0.011) were significantly associated with a primary malignancy (lung). The most common further investigations were aspiration cytology, ultrasound imaging and core biopsy, usually prior to parotidectomy. CONCLUSION If appropriate, parotid incidentalomas should be followed up with flexible endoscopy, skin examinations, and head and neck examinations. Ultrasound-guided core biopsy provides higher accuracy, avoiding repeat sampling and excision biopsy.

Abstract
In the staging of cancer patients, transient and spontaneously reversible bilateral adrenal hypertrophy may mimic a secondary localization of the disease. We discuss the case of an 82-year-old male patient with suspected testicular neoplasia in which abdominal CT examination reveals the onset of a bilateral macronodular adrenal enlargement, suggesting the diagnostic hypothesis of primary testicular neoplasia with secondary adrenal localization. The subsequent 18FDG-PET/CT study showed hyper-metabolism of the testicular mass, while the adrenal glands, surprisingly, did not show increased uptake of the radiotracer. After right orchifunicolectomy, primary testicular diffuse large B-cell lymphoma was diagnosed. The subsequent staging PET/CT study with iodine contrast medium, three months after the first CT examination, showed spontaneous complete regression of the adrenal hypertrophy without any use of drug therapy. The differential diagnosis of this finding considered the lack of hypermetabolism and the densitometric characteristics of the adrenal glands, the absence of possible pharmacological interactions throughout the time of the diagnostic procedures, and the available clinical-laboratory data. By excluding the main causes of adrenal hypertrophy, the most likely diagnostic hypothesis was transient adrenal hypertrophy due to stress induced by testicular lymphoma, meaning by stress a disturbance not only emotional but also an alteration of organic homeostasis. Our case suggests that the analysis of adrenal lesions appeared in cancer patients should take into account non-metastatic conditions that must be studied with a multimodal approach and with serial investigations.

Abstract
Incidental adnexal masses and uterine findings occur with a high frequency on cross-sectional imaging examinations, particularly in postmenopausal women in whom imaging is performed for a different reason. These incidentalomas encompass a gamut of potential pelvic gynecologic disorders. Most are benign ovarian cysts; however, other less commonly encountered disorders and improperly positioned gynecologic devices may be seen. A knowledge of the management recommendations for such pelvic incidental findings is critical to avoid unnecessary imaging and surgical interventions, as well as to avoid failure in diagnosis and management of some of these conditions.

Abstract
Incidentally detected adrenal nodules are common, and prevalence increases with patient age. Although most are benign, it is important for the radiologist to be able to accurately determine which nodules require further testing and which are safely left alone. The American College of Radiology incidental adrenal White Paper provides a structured algorithm based on expert consensus for management of incidental adrenal nodules. If further diagnostic testing is indicated, adrenal computed tomography is the most appropriate test in patients for nodules less than 4 cm. In addition to imaging, biochemical testing and endocrinology referral is warranted to exclude a functioning mass.

Abstract
Pituitary tumors are discovered either incidentally by imaging studies (incidentalomas) or via evaluation of certain clinical symptoms (symptomatic tumors). In this study, we first surveyed patients with incidentalomas who underwent surgery. Cases included 62.3% non-functioning adenomas (NFPAs), 14.5% functioning adenomas, and 13.8% Rathke's cleft cysts. Next, we compared the clinical features and surgical outcomes of 145 patients whose preoperative diagnosis was NFPA (incidentalomas [n = 79] vs. symptomatic tumors [n = 66]). The patients with incidentalomas were older (59.9 vs. 55.3 years, p < 0.05) and had smaller tumors compared with the patients with symptomatic tumors (mean maximum diameter: 23.1 vs. 27.5 mm, p < 0.01). The main reason for undergoing imaging studies was headache (n = 25) in the incidentaloma group and visual disturbance (n = 46) in the symptomatic tumor group. The incidence of preoperative pituitary hormone deficiencies was lower in the incidentaloma than symptomatic tumor group (growth hormone deficiency: 37.7% vs. 66.7%, p < 0.01; gonadotropin deficiency: 19.0% vs. 39.4%, p < 0.01; adrenocorticotropic hormone deficiency: 3.8% vs. 18.2%, p < 0.01; thyroid stimulating hormone deficiency: 6.3% vs. 12.1%, p = 0.25). Postoperative pituitary function was better preserved in the incidentaloma than symptomatic tumor group (no deficiency: 58.2% vs. 28.8%, p < 0.01). The difference in postoperative complications between groups was not statistically significant (incidentalomas vs. symptomatic tumors: 21.5% vs. 19.7%, p = 0.84). In conclusion, incidentalomas were detected while smaller size and lower incidence of hormone deficiency than symptomatic tumors, and the pituitary hormones were also preserved after surgery. It is important to observe incidentalomas carefully and to judge whether to operate appropriately before they become symptomatic tumors.

Abstract
Introduction and importance Adrenal schwannomas are extremely rare tumors often misdiagnosed. The patients are usually asymptomatic while some present with non-specific abdominal pain. Only a few cases are reported to date. Case presentation We here present a case of a 55-year-old Nepalese man presented with nonspecific abdominal pain at our Outpatient Department (OPD) found to have mass on ultrasonography of abdomen. On further investigation with Contrast Enhanced Computerized Tomography (CECT) of the abdomen and pelvis, a well-defined heterogeneous adrenal mass of size (7.8 ∗ 8.3 ∗ 6) cm with foci of calcification was seen in the left retroperitoneum. The intraoperative finding of adrenal mass and histopathology of resected mass was suggestive of schwannoma arising from the adrenal gland which was further confirmed by immunohistochemistry. Clinical discussion Adrenal schwannoma can mimic tumors like pheochromocytoma, adrenal adenoma, cortical carcinoma, neuroblastoma, and other masses. Only 1–3% of schwannomas are retroperitoneal. Radiological findings of this tumor are non-suggestive. The histological section shows spindle cells with Antoni A and Antoni B regions while positive staining of S-100 protein in Immunohistochemistry. Conclusion The diagnosis of adrenal schwannoma in the retroperitoneum is often challenging. The treatment of choice is surgical resection with a good prognosis. Adrenal schwannomas are extremely rare tumors. These tumors are mostly found incidentally and often asymptomatic. Complete surgical resection of the tumor is a must for good prognosis.

Abstract
Splenosis is a benign acquired condition, which appears after rupture of the spleen and heterotopic auto-transplantation. Mostly found as an incidental finding on cross-sectional imaging, definitive diagnosis is frequently made histologically after resection or tissue sampling. We report a case of a 36-year-old male patient who presented with increased susceptibility to infections, chronic fatigue, and a history of traumatic splenic rupture. Cross-sectional imaging showed perirectal formations within the mesorectal fascia, and extraperitoneal splenosis was suspected. Due to the radiologically unclear entity of the masses, diagnostic laparoscopy with tissue sampling was performed. Intraoperatively the masses turned out to be intraperitoneal. Histological workup showed splenic tissue, consistent with intraperitoneal splenosis after splenic rupture. In this article we want to discuss important imaging findings and their differentials, as well as clinical implications for this rare entity.

Abstract
We are reporting a very rare case in the current era of modern diagnostics of an incidentally detected Transitional Cell Carcinoma(TCC) renal pelvis, detected pathologically when Right laparoscopic radical nephrectomy specimen of lower pole mass(RCC) was processed, with no prior suspicion of TCC clinically or pre-operative imaging. A 75-year-old female with 4 × 4cm strongly enhancing lower pole renal mass on CTscan underwent a Laparoscopic Radical Nephrectomy. Surprisingly histopathological examination revealed a focus of low-grade TCC, arising from renal pelvis, completely separate from lower pole mass which was a clear cell RCC.

Abstract
Introduction Composite phaeochromocytoma is a tumour containing a separate tumour of neuronal origin in addition to a chromaffin cell tumour. This study reports on two cases from a single centre’s records and presents a systematic literature review of composite phaeochromocytomas. Methods In addition to describing 2 case reports, a systematic search of the Medline database from inception up to April 2020 was done for human case reports on composite phaeochromocytomas. Relevant titles and/or abstracts were screened, and full texts were reviewed to identify appropriate studies. Data was extracted and a descriptive analysis of presentation, clinical features, management strategies and outcomes was performed. The quality of included studies was assessed using a critical appraisal checklist. Results There were 62 studies included, with a total of 94 patients. Of 91 patients where data was available, the median (range) age of patients was 48 (4–86) years. Of 90 patients where information was provided, 57% were female. In at least 28% of patients, a genetic cause was identified. Common presenting features include abdominal pain, palpable mass, cardiovascular and gastrointestinal symptoms. The most common tumour component with phaeochromocytoma is ganglioneuroma; other components include ganglioneuroblastoma, neuroblastoma and malignant peripheral nerve sheath tumours. In patients with follow-up data (n=48), 85% of patients were alive and well at a median (range) follow-up time of 18 (0.5–168) months. Conclusion Composite phaeochromocytoma is a rare tumour, with a significant genetic predisposition. This review summarises available epidemiological data, which will be useful for clinicians managing this rare condition.

Abstract
BACKGROUND Hormonal disorders are often associated with abnormal levels of bone turnover markers (BTMs). N-terminal propeptide of type I procollagen (PINP) and serum C-terminal cross-linking telopeptide of type I collagen (CTX-I) are the reference markers of bone formation and bone resorption, respectively. METHODS A comprehensive literature search within the MEDLINE and Web of Science databases was performed. RESULTS Acromegaly is associated with higher BTM levels, which decrease during the remission after treatment. Adult-onset growth hormone deficiency is often associated with decreased BTM levels. Growth hormone replacement therapy stimulates bone turnover and increases BTM levels. Hypothyroidism is characterized by general slowing of bone metabolism which is reflected by lower BTM levels. The replacement thyroid hormone therapy increases the bone turnover rate and BTM levels increase. Patients with thyroid cancer receive a suppressive dose of thyroid hormones and may have slightly elevated BTM levels. Patients with overt hyperthyroidism had higher BTM levels and anti-thyroid therapy induces a rapid decrease in the BTM levels. Patients with overt primary hyperparathyroidism have higher BTM levels, whereas those with asymptomatic and normocalcemic hyperparathyroidism usually have normal BTM levels. Hypoparathyroidism is characterized by slightly decreased BTM levels. Cushing's syndrome is characterized consistently by markedly decreased osteocalcin concentration, whereas data on other BTMs are discordant. CONCLUSIONS BTMs help us to better understand mechanisms of the impact of hormonal disorders and their treatment on bone metabolism. However, it is unknown whether BTMs may be used to monitor the effect of their treatments on bone in the clinical practice.

Abstract
Radiologists very frequently encounter incidental findings related to the thyroid gland. Given increases in imaging use over the past several decades, thyroid incidentalomas are increasingly encountered in clinical practice, and it is important for radiologists to be aware of recent developments with respect to workup and diagnosis of incidental thyroid abnormalities. Recent reporting and management guidelines, such as those from the American College of Radiology and American Thyroid Association, are reviewed along with applicable evidence in the literature. Trending topics, such as artificial intelligence approaches to guide thyroid incidentaloma workup, are also discussed.

Abstract
BACKGROUND Up to 70% of adrenal masses detected in patients affected by extra-adrenal malignancy are metastatic lesions. Therefore, detection of an adrenal mass in patients with active or previous malignancy requires a careful differential diagnostic workup. 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) is increasingly being used to determine the malignant potential of adrenal lesions. CLINICAL CASE We report the case of a 64-year-old man who had a single adrenal metastasis due to non-small-cell lung carcinoma developing on a pre-existing benign adrenal lesion. This metastasis occurred in a phase of perceived oncological remission and was detected thanks to 18F-FDG-PET/CT showing a focal adrenal uptake. Contrast-enhanced computed tomography (CT), performed as part of oncological follow-up, and MRI with chemical shift sequences did not lead to the correct diagnosis. The patient underwent laparoscopic adrenalectomy and the pathological evaluation confirmed a lung carcinoma metastasis. CONCLUSION The present case highlights the peculiarity of the follow-up of adrenal masses in cancer patients and the primary role of 18F-FDG-PET/CT in the management of such patients.

Abstract
INTRODUCTION Schwannomas are rare, slow-growing, usually benign tumors that originate from myelin-producing Schwann cells. Adrenal schwannomas are an exceptionally rare subset of these tumors, with few cases reported in the literature. PRESENTATION OF CASE We present the case of a 44-year old female patient being evaluated for chronic abdominal pain at the outpatient clinic. Clinical and laboratory workup was unremarkable. An abdominal CT scan was performed, revealing a left suprarenal solid mass (5 × 6 cm). Surgical resection of the adrenal gland was performed, given the patient's symptoms, the size of the tumor, and its malignant potential. The patient completed the postoperative period satisfactorily, and her symptoms improved. Histopathological findings were compatible with a benign adrenal schwannoma. DISCUSSION Schwannomas generally appear in the head, neck and extremities, with the vestibulocochlear nerve being the most frequently involved site. Retroperitoneal schwannomas account for 1-5% of retroperitoneal masses and comprise only 1-3% of all schwannomas. Their incidence increases with age, from 4% in the general population, reaching 7% in patients over 70 years of age. CONCLUSION Adrenal incidentalomas represent a diagnostic challenge. Because of the malignant potential of large (> 4 cm) adrenal masses and the lack of characteristic findings using conventional imaging techniques and laboratory diagnostic tools, surgical excision with histopathology and immunohistochemistry analysis are required for definitive diagnosis and optimal management.

Abstract
Incidentally discovered adrenal alterations should be separated into those without any clinical importance and adrenal diseases that have to be surgically or conservatively treated. Before operative treatment, in addition to the possible different functional activity of tumors, a differentiation must be made between sporadically arising singular or multiple adrenal tumors or nodular adrenal hyperplasia, adrenal tumors as part of a familial syndrome and metastases of other primary malignant tumors into the adrenal glands. Benign hormonally active adrenal tumors as well as questionable malignant tumors of the adrenal cortex are resected by minimally invasive techniques. For large malignant tumors infiltrating into surrounding tissues and tumors with proven lymph node metastases, the primarily open approach is indicated. Patients with adrenal diseases should always undergo an interdisciplinary assessment and in cases with clear indications for surgery, sometimes transferred to a center with experience in surgery and postoperative management of these patients.

Abstract
BACKGROUND Patients diagnosed with cancer do not have sufficient clinical data for the management of incidental parotid lesions. We aimed to reveal the importance of randomized parotid lesions encountered during oncologic F-18 fluorodeoxyglucose positron emission tomography (FDG PET/CT) imaging in our clinical practice and the diagnostic algorithm of such lesions. METHODS We performed a database search of PET/CT records generated from 2009 to 2015 for "parotid" in reports of patients who underwent PET/CT examination for a known malignancy elsewhere, or cancer screening. RESULTS Incidental parotid FDG uptake on PET/CT had a prevalence of 1.1%. The incidence of parotid metastasis in our series was 36.4%, and 75% of them had malign melanoma metastasis. Of the 11 cases, 5 were of Warthin tumours, and Warthin tumours showed stronger GLUT1 expression than metastatic parotid lesions. CONCLUSION In patients with malignancy elsewhere, focal involvement of FDG by the parotid gland, especially if malignant melanoma or SCC is absent, should not be considered a metastatic disease without histopathologic confirmation. If parotid disease would change the patient's treatment plan and disease stage, the parotid lesion should be evaluated by additional methods, such as fine needle aspiration biopsy.

Abstract
OBJECTIVES To present our center's experience in the management of adrenal myelolipoma in the context of shifting from the open to the laparoscopic adrenalectomy approach. MATERIALS AND METHODS A retrospective search of our center's records was done for reported cases of adrenal myelolipoma during the period July 2001-June 2016. All the cases with histopathologically-documented adrenal myelolipoma diagnosis were included. Relevant demographic and clinical variables were studied with a comparison between the open and laparoscopic approaches. RESULTS Of more than 82,000 urological surgeries, 238 adrenalectomies were done with only 22 cases of myelolipoma that had a mean age and body mass index of 52.4 ± 10.3 years and 30.23 kg/m2, respectively. The main clinical presentation was accidental discovery. The largest dimension of tumors varied from 6 to 16 cm. Computed tomography described a characteristic picture of hypodense heterogeneous adrenal tumors in all cases, while magnetic resonance imaging was indicated for malignancy suspicion in only 5 cases. Adrenal tumor markers were normal in all cases. Open and transperitoneal laparoscopic adrenalectomies were used in 14 and 8 cases, respectively. The latter approach was insignificantly advantageous in the need for blood transfusion, postoperative pain degree, need for analgesia, and hospital stay duration (p = 0.22). Histo-pathological examination revealed benign adipose tissue and myeloid cells and confirmed the diagnosis of adrenal myelolipoma in all cases. CONCLUSIONS Adrenal myelolipoma is a rare non-functioning benign tumor. Laparoscopic excision seems to be a promising alternative approach to the traditional open adrenalectomy, even in the context of large tumors and obesity.

Abstract
PURPOSE To evaluate the impact of gender and year at surgery on clinical presentation and postoperative outcomes in acromegaly. METHODS Retrospective review of patients operated between 1994 and 2016 to compare presentation and outcomes in groups defined by gender and year of surgery. Kaplan-Meier survival analyses with a composite endpoint (recurrence, reoperation, and radiation) were used for gender comparison and Youden indices for biochemical remission rates changes during study period. RESULTS Primary indications for evaluation were phenotype, neurological symptoms, incidentaloma, hypogonadism, and galactorrhea. At surgery, men (N = 54) were younger (43.6 ± 12.7 years) than women (N = 58, 48.7 ± 12.3, P = 0.04). Male:female ratios before and after age 50 were 1.4 and 0.6 respectively. Men had higher mean IGF-1 levels (874 ± 328 vs 716 ± 296, P < 0.01) and smaller tumors (1.8 ± 1.3 cm vs 2.3 ± 1.5, P = 0.04). Postoperative remission rates were comparable (51% men, 56% women) and inversely associated with cavernous sinus invasion and GH levels. Women had longer mean follow-up (5.2 ± 3.4 years vs 3.6 ± 3.6 men, P = 0.02) and longer endpoint-free survival (P < 0.01). At last follow-up, 89.6% women and 70% men had normal IGF-1 levels (P = 0.03). Postoperative remission rates were higher in patients operated after February 15, 2011 (67.35 vs 43.5% previously, P = 0.01). In late vs early surgery group, physical changes as main indication for screening decreased (54 vs 30%, P < 0.01), while incidentaloma and hypogonadism increased. Median GH levels were lower in late vs early surgery group (P = 0.03). CONCLUSION We demonstrate gender-specific characteristics and an evolving spectrum of clinical presentation with implications for earlier diagnosis and personalized management of acromegaly.

Abstract
Leiomyoma is a benign tumor of smooth muscle origin. Primary leiomyoma of the adrenal gland is very rare. Adrenal tumors are often diagnosed during the ultrasound or computerized tomography (CT) study as incidentaloma. According to the literature review, up to 2018, the largest size of adrenal leiomyoma which had ever been reported was 12 × 10 × 8 cm in dimension (Maher et al.). Herein, we report the largest adrenal leiomyoma with the tumor mass of 600 g (14,1x11,4x10,1 cm) from a female patient admitted to our hospital.

Abstract
SUMMARY Primary aldosteronism (PA) is more common than expected. Aberrant adrenal expression of luteinizing hormone (LH) receptor in patients with PA has been reported; however, its physiological role on the development of PA is still unknown. Herein, we report two unique cases of PA in patients with untreated Klinefelter's syndrome, characterized as increased serum LH, suggesting a possible contribution of the syndrome to PA development. Case 1 was a 39-year-old man with obesity and hypertension since his 20s. His plasma aldosterone concentration (PAC) and renin activity (PRA) were 220 pg/mL and 0.4 ng/mL/h, respectively. He was diagnosed as having bilateral PA by confirmatory tests and adrenal venous sampling (AVS). Klinefelter's syndrome was suspected as he showed gynecomastia and small testes, and it was confirmed on the basis of a low serum total testosterone level (57.3 ng/dL), high serum LH level (50.9 mIU/mL), and chromosome analysis. Case 2 was a 28-year-old man who had untreated Klinefelter's syndrome diagnosed in his childhood and a 2-year history of hypertension and hypokalemia. PAC and PRA were 247 pg/mL and 0.3 ng/mL/h, respectively. He was diagnosed as having a 10 mm-sized aldosterone-producing adenoma (APA) by AVS. In the APA, immunohistochemical analysis showed co-expression of LH receptor and CYP11B2. Our cases of untreated Klinefelter's syndrome complicated with PA suggest that increased serum LH levels and adipose tissues, caused by primary hypogonadism, could contribute to PA development. The possible complication of PA in hypertensive patients with Klinefelter's syndrome should be carefully considered. LEARNING POINTS The pathogenesis of primary aldosteronism is still unclear. Expression of luteinizing hormone receptor has been reported in aldosterone-producing adenoma. Serum luteinizing hormone, which is increased in patients with Klinefelter's syndrome, might contribute to the development of primary aldosteronism.

Abstract
OBJECTIVES To draw up guidelines for ENT management associated with dental implant surgery with or without sinus lift. MATERIALS AND METHODS The methodology followed the rules of laid down by the French Health Authority (HAS): "Methodological bases for drawing up professional recommendations by formalized consensus". The chosen method was the RAND/UCLA "RAND appropriateness method" (short version). RESULTS In the pre-implantation check-up, it is recommended to systematically screen for sinonasal pathology on medical interview and to favor 3D CT or cone-beam imaging. It is recommended that imaging include the entire maxillary sinus when the patient does not have sinonasal history or functional signs on interview. Otherwise, examination of all sinonasal cavities is recommended. This attitude enables simultaneous analysis of maxillary infrastructure for pre-implantation work-up and assessment of sinonasal cavity status. Sinus mucosal incidentalomas are very common in the healthy population and must be assessed with reference to the clinical, endoscopic and radiological context. CONCLUSION This formalized expert consensus establishes a common base of knowledge, to clarify the issues and clinical situations and to standardize practices.

Abstract
PURPOSE Childhood-onset craniopharyngiomas (CP) are diagnosed due to clinical symptoms (symCP) or incidentally (incCP). We investigated clinical manifestations and outcome in incCPs and symCPs. METHODS IncCP were discovered in 4 (3 m/1 f) and symCP in 214 (101 m/113 f) CP recruited 2007-2014 in KRANIOPHARYNGEOM 2007. Age, sex, height, body mass index (BMI), tumor volume, degree of resection, pre- and postsurgical hypothalamic involvement/lesions, pituitary function and outcome were compared between both subgroups. RESULTS Reasons for imaging in incCP were cerebral palsy, head trauma, nasal obstruction, and tethered-cord syndrome, whereas headache (44%), visual impairment (25%), and growth retardation (17%) lead to imaging in symCP. Tumor volume at diagnosis was smaller in incCP (median 2.39 cm3; range 0.14-4.10 cm3) when compared with symCP (15.86 cm3; 0.002-286.34 cm3). Age, gender, BMI, height, hydrocephalus, tumor location, and hypothalamic involvement at diagnosis of incCP were within the range of these parameters in symCP. Complete resections were achieved more frequently (3/4 patients) in incCP when compared with symCP (20%). Surgical hypothalamic lesions were distributed similar in incCP and symCP. Irradiation was performed only in symCP (33%). No noticeable differences were observed concerning survival rates, endocrine deficiencies, BMI, height, functional capacity and quality of life of the 4 incCP cases when compared with the symCP cohort. CONCLUSIONS IncCP are rare (1.8%) and characterized by lack of endocrine deficiencies, resulting in normal height and BMI, no hydrocephalus, and smaller tumor volume at diagnosis when compared with symCPs. Outcome of the observed incCP is similar with symCP. CLINICAL TRIAL REGISTRATION NUMBER NCT01272622.

Abstract
Adrenocortical carcinomas (ACC) are rare but highly aggressive tumors. It is very difficult to differentiate small locally limited ACCs from benign adenomas. A spontaneous density >10 Hounsfield units in non-enhanced CT scan and a slow washout after contrast injection are suspicious of malignancy but with a low specificity. Preoperatively, a hormonal work-up is mandatory for all adrenal tumors. Each patient should be discussed in an interdisciplinary board. For non-metastatic ACCs (ENSAT stages I-III) radical resection is the treatment of choice. R0-resection and avoiding violation of the tumor capsule are the most important prognostic factors for long-term survival. Although discrepant reports regarding the benefits of lymphadenectomy have been published, lymph node dissection at least in the periadrenal area and in the renal hilum (optional extension to paraaortal and paracaval nodes) should be performed in the case of lymph node involvement. The role of prophylactic lymphadenectomy needs to be analyzed in further studies. The gold standard remains the open approach but minimally invasive procedures are also an option, especially in stage I-II tumors, if the principles of oncological surgery are respected. In this case, long-term survival rates are comparable. As local recurrence rates are lower and time to local recurrence is longer in patients who are operated on at a dedicated center (>10 adrenalectomies/year), adrenalectomy for ACC should be performed by an experienced surgeon.

Abstract
PURPOSE Guidelines on pituitary incidentalomas evaluation and management are limited to adults since there are no data on this matter in the paediatric population. We aim to analyse the morphologic characteristics, hormonal profile and follow-up of these lesions in children. METHODS We have searched for pituitary incidentalomas in the neuroimaging reports and electronic medical records of the Paediatric Endocrinology Clinic of our centre. Patients with 18 years-old or less were included. RESULTS Forty-one incidentalomas were identified, 25 of them (62.4%) in females. The mean age at diagnosis was 12.0 ± 4.96 years-old. Headaches were the main reason that led to image acquisition (51.2%) and MRI was the imaging method that detected the majority of the incidentalomas (70.7%). The most prevalent lesion was pituitary hypertrophy (29.3%), which was mainly diagnosed in female adolescents (91.7%), followed by arachnoid cysts (17.1%), pituitary adenomas (14.6%) and Rathke's cleft cysts (12.2%). Most patients (90.2%) did not present clinical or laboratorial findings of hypopituitarism or hormonal hypersecretion. Four patients presented endocrine dysfunction: three had growth hormone deficiency and one had a central precocious puberty. Twenty-three patients (56.1%) underwent imagiological revaluation during a median follow-up time of 24.6 months (interquartile range 5.07). None of them presented dimensional progression. CONCLUSIONS To the best of our knowledge, this is the first series of pituitary incidentalomas in pediatric age. Comparing our series with those conducted in adults, we have observed a higher preponderance of pituitary hypertrophy over adenomas, a lower prevalence of hormonal hyper/hyposecretion and lower risk of dimensional progression during follow-up.

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
Context Adrenal incidentalomas (AI) represent an increasingly common problem in modern endocrine practice. The diagnostic approach to AIs can be challenging and occasionally reveals surprising features. Here we describe two rare cases of complex adrenal lesions consisting of phaeochromocytomas with synchronous metastases from extra-adrenal primaries. Case descriptions Patient 1 - a 65-year-old gentleman with a newly diagnosed malignant melanoma was found to harbour an adrenal lesion with suspicious radiographic characteristics. Percutaneous adrenal biopsy was consistent with adrenocortical adenoma. After excision of the skin melanoma and regional lymphatic metastases, he was followed up without imaging. Three years later, he presented with abdominal discomfort and enlargement of his adrenal lesion, associated with high plasma metanephrines. Adrenalectomy revealed a mixed tumour consisting of a large phaeochromocytoma with an embedded melanoma metastasis in its core. Patient 2 - a 63-year-old lady with a history of NF-1-related phaeochromocytoma 20 years ago and previous breast cancer presented with a new adrenal lesion on the contralateral side. Plasma normetanephrine was markedly elevated. Elective adrenalectomy revealed an adrenal tumour consisting of chromaffin cells intermixed with breast carcinoma cells. Conclusions Adrenal incidentalomas require careful evaluation to exclude metastatic disease, especially in the context of a history of previous malignancy. Adrenal biopsy provides limited and potentially misleading information. Phaeochromocytomas are highly vascularised tumours that may function as a sieve, extracting and retaining irregularly shaped cancer cells, thereby yielding adrenal masses with intriguing dual pathology. Learning points: Adrenal incidentalomas require careful evaluation focused on exclusion of underlying hormone excess and malignant pathology. Adrenal biopsy can be misleading and should only be considered in select cases. Phaeochromocytomas harbouring intratumoural metastases from other, extra-adrenal primary malignancies represent rare pathological entities that highlight the complexities that can be presented by adrenal tumours.

Abstract
Multiparametric magnetic resonance imaging (MRI) of the prostate is a powerful and increasingly utilized imaging study for the diagnosis, staging, and surveillance of prostate cancer. With greater adoption by clinicians, it is becoming more common for incidental findings to be first detected on prostate MRI. Inadequate description of clinically significant findings may not prompt appropriate patient management, while over-reporting of indolent findings comes at increased patient anxiety, cost of workup, and iatrogenic risk. This review article aims to improve awareness, review pathophysiology, and present key imaging features of incidental findings seen on prostate MRI, ranging from common to rare and from benign to clinically significant.

Abstract
PURPOSE Thyroid incidental uptake is defined as a thyroid uptake incidentally detected by imaging examinations performed for non-thyroid disease. The aim of this study was to establish the prevalence and the pathological nature of focal thyroid incidental uptake (FTIU) among patients studied with 18F-choline-PET/CT. MATERIALS AND METHODS We retrospectively evaluated 368 patients who performed 18F-choline-PET/CT between June 2016 and August 2018. The PET images were analyzed visually and semi-quantitatively by measuring the maximum standardized uptake value (SUVmax) and the mean SUV (SUVmean) of the thyroid gland and of the FTIU; every focal thyroid uptake deviating from physiological distribution and background was considered FTIU. Final diagnosis of FTIU was obtained by cytological or histological examination after surgery. RESULTS The average SUVmax and SUVmean of thyroid gland in population were 3 and 1.8. Among 368 patients, FTIU was identified in nine cases (2.4%) and eight underwent further investigations to determine the nature. Two FTIU were classified as malignant (thyroid carcinoma), whereas five were benign (three nodular hyperplasia, one follicular adenoma, one Hurtle cell adenoma) and one indeterminate at cytological examination. In malignant lesions, average SUVmax was 9.6 and 4.5, respectively, while average SUVmean was 5.3 and 2.9, respectively. Average SUVmax and SUVmean of benign lesions were 4.9 and 3.2 and of the indeterminate lesion 5 and 3, respectively. CONCLUSIONS 18F-choline-PET/CT FTIU may be a relevant diagnostic reality, which requires further investigations and affects management, especially considering that, despite being mainly benign, also malignancy is possible.
