Technetium-99m methoxy isobutyl isonitrile (99m Tc-MIBI; sestamibi) single-photon emission computed tomography (SPECT)/computed tomography (CT) performed for preoperative localization of parathyroid adenomas or for other indications can reveal incidentalomas. Interpretation of such findings can be challenging, particularly when thyroid or other endocrine tumors are also present. Preoperative staging of a 59-year-old female patient with medullary thyroid carcinoma (MTC) showing moderate hypermetabolism on 18 F-fluorodeoxyglucose positron emission tomography/CT also detected a slightly hypermetabolic pulmonary nodule (standardized uptake value normalized by body weight max = 2...

Pancreatic incidentalomas are increasingly recognized entities that occur as a fallout of widespread availability of high definition imaging technology. These lesions offer diagnostic dilemmas to both clinicians and radiologists alike. Nevertheless, it is the advancement in diagnostic radiology that comes to the rescue in the management of these not-so-uncommon lesions.

Objective: Endoscopic ultrasound-guided fine-needle aspiration cytology (EUS-FNAC) is a precise and safe technique that provides both radiological and pathological diagnosis with a better diagnostic yield and minimal adverse events. EUS-FNAC led to the remarkable increase in the detection rate of incidentaloma found during radiologic staging or follow-up in various malignancy or unrelated conditions. Aims: We did this preliminary study with an aim to evaluate the role of EUS-FNA in diagnosing and classifying adrenal lesions, clinical impact, and compare the outcome with the previously published literature...

BACKGROUND: Adrenal hemorrhage (AH) is a rare condition that can lead to acute adrenal insufficiency and may be fatal. The risk factors of AH include focal adrenal lesion, abdominal trauma and anticoagulation therapy. The clinical manifestation of AH varies widely; the symptoms may be related to adrenal insufficiency or may reflect multiple organ failure. However, in many cases, the course of AH is asymptomatic. OBJECTIVES: The study is a retrospective analysis of 23 cases of AH, whose aim is to discuss the etiology and the management of selected patients, as well as a literature review...

Background: Adrenal incidentalomas (AIs) are present in 4% of adults. As many as 30% may secrete cortisol autonomously in the absence of specific signs of overt hypercortisolism, in a phenomenon called subclinical hypercortisolism (SH). Diagnosis of SH is established by serum cortisol resistance to dexamethasone suppression. Methods: We compared serum cortisol concentrations, as determined by radioimmunoassay (RIA) and liquid chromatography/tandem mass spectronomy (LC/MS-MS), in 73 patients with AI group (52 with unilateral AI) and 34 control subjects in 3 scenarios: basal; after 1-mg dexamethasone suppression; and after 0...

Patients with adrenal incidentaloma (AI) and subclinical hypercortisolism (SH) show a high prevalence of cardiovascular risk factors and an increased prevalence and incidence of cardiovascular events. Furthermore, some recent data suggest that in these patients, the cardiovascular mortality is also increased. Unfortunately, to date, the diagnosis of SH is still a matter of debate, and, therefore, it is still not possible to address the treatment of choice (i.e. surgical or conservative approach) in many AI patients...

Distinguishing adrenal incidentalomas (5% of all abdominal CT scans) from metastasis is a frequent diagnostic challenge in primary malignancies with a propensity for adrenal spread, such as lung cancer. Adrenal myelolipoma and adenoma can be definitively characterized as benign by demonstrating gross and microscopic fat, respectively, on CT and MRI and an absence of abnormal uptake on PET. Unfortunately, adrenal sampling is frequently necessary in indeterminate cases for adequate staging of extra-adrenal primary malignancy...

BACKGROUND: Measurement of serum dexamethasone during the overnight dexamethasone-suppression test (ONDST) has been recommended to reduce false positive results when investigating Cushing's syndrome or increasingly commonly found adrenal incidentalomas. Despite this, there remains a paucity of well-validated dexamethasone methods currently available. Here, we describe the development of a rapid and sensitive LC-MS/MS serum dexamethasone assay and validate its utility in a cohort of postmenopausal females...

BACKGROUND: Many attribute the rise in incidence of thyroid cancer to a deluge of radiologically identified incidental thyroid nodules. The clinical implications are unclear. METHODS: A review was performed of all patients who underwent fine-needle aspirations of thyroid nodules by our academic medical center's Endocrinology Division between 2006 and 2010. Medical records were reviewed to identify whether the thyroid nodule was discovered incidentally or by palpation...

BACKGROUND: Low-grade incomplete post-dexamethasone cortisol suppression in patients with adrenal incidentalomas -recently defined as possible autonomous cortisol secretion (pACS)- has been associated with increased cardiovascular events and mortality. However, prospective studies documenting cardiac abnormalities in these patients are lacking. SUBJECTS AND METHODS: Between July 2016 and September 2017, 71 consecutive patients with adrenal lesions were prospectively screened for hypercortisolism by dexamethasone suppression test (NCT02611258)...

CONTEXT: To investigate whether any association between chemical shift magnetic resonance (MRI) findings, cortisol secretion and pathological findings exist that could predict subclinical hypercortisolism (SCH) in patients with adrenal incidentalomas (AI). DESIGN: Retrospective, cross sectional study in a tertiary centre. PATIENTS: Sixty-eight subjects with AIs and 13 patients with Cushing's syndrome (CS). Patients with AIs were categorized according to cortisol levels post 1mg dexamethasone (post-DST)...

Thyroid follicular cells, as well as adrenocortical cells, are endowed by an intrinsic heterogeneity regarding their growth potential, in response to various stimuli. This heterogeneity appears to constitute the underlying cause for the focal cell hyperplasia and eventually the formation of thyroid and adrenal nodules, under the influence of growth stimulatory factors. Among the main stimulatory factors are the pituitary tropic hormones, thyroid-stimulating hormone (TSH) or thyrotropin and adrenocorticotropic hormone (ACTH), which regulate the growth and function of their respective target cells, and the insulin/insulin-like growth factor system, that, through its mitogenic effects, can stimulate the proliferation of these cells...

CONTEXT: the recent recommendations of the European endocrine society states that the performance of computed tomography (CT) to characterize true adrenal incidentalomas (AIs) remains debatable. OBJECTIVE: to determine relevant thresholds for usual CT parameters for the diagnosis of benign tumors using robust reference standard amongst a large series of "true" AIs recruited in an endocrinological setting. DESIGN: retrospective study of 253 AIs in 233 consecutive patients explored in a single university hospital: 183 adenomas, 33 pheochromocytomas, 23 adrenocortical carcinomas, 5 other malignant tumors and 9 other benign tumors...

BACKGROUND: A substantial proportion of all pheochromocytomas is currently detected during the evaluation of an adrenal incidentaloma. Recently it has been suggested that biochemical testing to rule out pheochromocytoma is unnecessary in case of an adrenal incidentaloma with an unenhanced attenuation value ≤10 Hounsfield Units (HU) at computed tomography (CT). OBJECTIVES: We aimed to determine the sensitivity of the 10 HU threshold value to exclude a pheochromocytoma...

A substantial literature documents inappropriate usage of gastrointestinal endoscopy in a variety of clinical settings. Overusage of endoscopy appears to be common, and 30% or more of procedures performed in some clinical settings have questionable indications. The potential reasons for overuse of endoscopy are multiple, and include cancer phobia, fear of medical malpractice litigation, profit motive, the investigation of "incidentalomas" found on other imaging, and under-appreciation of the delayed harms of endoscopy, among other reasons...

Recently discovered mutations of NR3C1 gene, encoding for the Glucocorticoid Receptor (GR), in patients with glucocorticoid resistance and bilateral adrenal incidentalomas prompted us to investigate whether GR mutations might be associated with adrenal hyperplasia. OBJECTIVE: The multicenter French Clinical Research Program (Muta-GR) was set up to determine the prevalence of GR mutations and polymorphisms in patients harboring bilateral adrenal incidentalomas associated with hypertension and/or biological hypercortisolism without clinical Cushing's signs...

Audit is a clinical instrument of government characterized by a whole process of evaluation inter pares to improve medical behaviors in the clinical practice. Different endocrinopathies are underestimated in the clinical and diagnostics practice but they can be a real problem in patients admitted in the departments of Internal Medicine. The Adrenal Incidentaloma (AI) is an accidental discovery with an incidence equal to 4% in radiologic studies but it's rarely considereted in the internal disorders. In the departments of Internal Medicine are hospitalized each year approximately 1...

Objective Thyroid cancer incidence is increasing. The rise is most pronounced for microcancers (≤10 mm, T1a). In 2006, landmark European and American guidelines for the management of thyroid cancer were published. We studied thyroid cancer characteristics and initial management before and after 2006. Methods We conducted a retrospective observational study of non-medullary thyroid cancer patients that underwent thyroidectomy in two Belgian referral centres comparing pre-, per- and post-operative management in a cohort before and after 2006...
