Primary aldosteronism (PA), also known as Conn's syndrome, is a frequent cause of secondary hypertension. If PA is due to a documented unilateral adrenal adenoma, adrenalectomy is the treatment of choice. Endocrine Society guidelines suggest monitoring potassium after adrenalectomy, while there is no mention of sodium disorders after surgery. Here we report the case of a patient with Conn's syndrome who developed hyponatremia after surgery. This was an unexpected event in the course of the treatment, which sheds light on the fact that low levels of aldosterone strongly influence sodium concentration, and advises clinicians to monitor sodium after adrenalectomy...

Adrenal collision tumors (ACTs), in which distinct tumors coexist without histological intermingling in the same adrenal gland, are rare and their actual prevalence is unknown. ACTs commonly consist of adrenal cortical adenoma, myelolipoma, or metastatic malignant tumor. We report a 58-year-old woman with a past history of breast cancer, who presented with a 1 month history of fevers, chills, and abdominal fullness. The physical examination and the laboratory data including endocrine studies were unremarkable...

Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively...

The adrenal glands in children can be affected by a variety of benign lesions. The diagnosis of adrenal lesions can be challenging, but assessment of morphologic changes in correlation with the clinical presentation can lead to an accurate diagnosis. These lesions can be classified by their cause: congenital (eg, discoid adrenal gland, horseshoe adrenal gland, and epithelial cysts), vascular and/or traumatic (eg, adrenal hemorrhage), infectious (eg, granulomatous diseases), enzyme deficiency disorders (eg, congenital adrenal hyperplasia [CAH] and Wolman disease), benign neoplasms (eg, pheochromocytomas, ganglioneuromas, adrenal adenomas, and myelolipomas), and adrenal mass mimics (eg, extralobar sequestration and extramedullary hematopoiesis)...

Discoveries of somatic mutations permit the recognition of subtypes of aldosterone-producing adenomas (APAs) with distinct clinical presentations and pathological features. Catenin β1 (CTNNB1) mutation in APAs has been recently described and discussed in the literature. However, significant knowledge gaps still remain regarding the prevalence, clinical characteristics, pathophysiology, and outcomes in APA patients harboring CTNNB1 mutations. Aberrant activation of the Wnt/β-catenin signaling pathway will further modulate tumorigenesis...

GIP-dependent Cushing's syndrome is caused by ectopic expression of glucose-dependent insulinotropic polypeptide receptor (GIPR) in cortisol-producing adrenal adenomas or in bilateral macronodular adrenal hyperplasias. Molecular mechanisms leading to ectopic GIPR expression in adrenal tissue are not known. Here we performed molecular analyses on adrenocortical adenomas and bilateral macronodular adrenal hyperplasias obtained from 14 patients with GIP-dependent adrenal Cushing's syndrome and one patient with GIP-dependent aldosteronism...

INTRODUCTION: The ACTH receptor (ACTHR) is primarily expressed in the adrenal cortex. Previous studies focused on the regulatory function of ACTHR in glucocorticoid secretion, but research on adrenal tumours is rare. The aim of this study was to evaluate ACTHR expression in common adrenal adenomas and investigate its influence on adrenal tumorigenesis using adrenocortical H295R cells. MATERIALS AND M: ETHODS: Real-time polymerase chain reaction and western blot were used to detect the expression of ACTHR in 18 aldosterone-producing adenomas, 16 cortisol-producing adenomas, nine non-functional adenomas, and 12 normal adrenal samples...

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of Cushing syndrome, especially the isolated form without Carney complex, associated with germline mutations in PRKAR1A, the protein kinase A regulatory subunit type 1 alpha gene. We report a 31-year-old female who presented with secondary amenorrhea, cushingoid appearance, and hypertension without Carney complex. Biochemical laboratory examinations confirmed the ACTH-independent adrenal Cushing syndrome with negative Liddle test. A small right adrenal adenoma of 0...

Primary aldosteronism (PA) is a group of disorders in which aldosterone is excessively produced. These disorders can lead to hypertension, hypokalemia, hypervolemia and metabolic alkalosis. The prevalence of PA ranges from 5% to 12% around the globe, and the most common causes are adrenal adenoma and adrenal hyperplasia. The importance of PA recognition arises from the fact that it can have a remarkably adverse cardiovascular and renal impact, which can even result in death. The aldosterone-to-renin ratio (ARR) is the election test for screening PA, and one of the confirmatory tests, such as oral sodium loading (OSL) or saline infusion test (SIT), is in general necessary to confirm the diagnosis...

Radioisotope-labeled prostate-specific membrane antigen (PSMA) tracers have been proven accurate for detection of prostate cancer localizations. Uptake of those tracers in other malignant and benign lesions has been reported, including faint accumulation of Ga-PSMA-HBED-CC in adrenal adenoma. A 77-year-old man with prostate carcinoma was scanned with F-DCFPyL, a promising F-labeled PSMA ligand, for prostate-specific antigen progression while on luteinizing hormone-releasing hormone agonist therapy. The PET/CT shows F-DCFPyL uptake in bilateral enlarged adrenals...

Cushing syndrome (CS) during pregnancy is a rare condition with only a few cases reported in the literature. Misdiagnosis of CS is common because of overlapping features like fatigue, weight gain, striae and emotional changes that can occur during normal pregnancy. Changes in maternal hormones and their binding proteins complicate assessment of glucocorticoid hormone levels during gestation. CS during pregnancy is most frequently due to an adrenal adenoma and to a lesser degree to adrenocorticotropic hormone (ACTH) hypersecretion by a pituitary adenoma...

We report a case of spontaneous retroperitoneal haemorrhage by bleeding of an adrenal adenoma. Retroperitoneal haemorrhages are rarely encountered in practice, but must be rapidly diagnosed due to the life threatening risk. The etiologies, clinical assessment, management and differential diagnosis of spontaneous retroperitoneal haemorrhages are discussed.

Background: Adrenal incidentaloma refers to the incidental finding of a tumor in the adrenal gland, where nonfunctional forms are the most common variant. Myelolipoma is a rare (0.08-0.4%) occurrence characterized by adipose and hematopoietic tissue. The aim of this case report is to describe the diagnosis and appropriate management of a myelolipoma in an asymptomatic patient, which was originally considered an incidental hepatic hemangioma prior to being identified as a giant adrenal adenoma. Case description: The patient was a 54 year old obese female with a recent diagnosis of diabetes type II and dyslipidemia with recent ultrasound imaging suggestive of a hepatic hemangioma...

BACKGROUND: Adrenal adenomas are benign tumors often discovered incidentally, and >70% are hormonally inactive. The remaining subset may produce excess aldosterone, cortisol, or catecholamine. Perioperative outcomes after adrenalectomy for such "hormonally active" tumors remain unclear. This study examines in-hospital outcomes after unilateral adrenalectomy for hormonally active tumors. METHODS: A retrospective review was performed using the Nationwide Inpatient Sample (2006-2011) to identify patients undergoing unilateral adrenalectomy for hormonally active or inactive tumors...

Cushing's syndrome is a rare disease. Cushing's syndrome presenting as acute psychosis is an exceptional occurrence. We present the case of a 37-year-old woman who was admitted with acute confusion associated with mild hypercalcaemia and was subsequently diagnosed with parathyroid and adrenal adenomas. Our hospital sees approximately 6000 endocrine patients per year, with an incidence of around four Cushing's cases annually. This is the first such case to occur in our hospital and one of few described in the literature...
