Adrenal Glands: Anatomy, Embryology, Physiology. Adrenal pathology can manifest in various ways, including the following. Palpable abdominal mass. Incidental finding of an adrenal mass on imaging. Mineralocorticoid excess. Androgen excess. Catecholamine excess. Paraneoplastic process. Ambiguous genitalia. In the newborn period, ambiguous genitalia, with or without associated salt wasting, is strongly suggestive of congenital adrenal hyperplasia. This is an inherited autosomal recessive disorder caused by deficiency of 1 of the enzymes necessary for adrenal steroid production, especially cortisol. Cortisol deficiency leads to excessive secretion of adrenocorticotropic hormone (ACTH) with resultant bilateral adrenal hyperplasia; thus, a deficiency of the end products of blocked pathways and excess production of steroids in open pathways results. The most common enzyme deficiency is 2. This is seen in 2 forms: classic (more severe) and nonclassic (less severe). Classic form. The classic form, which occurs with an incidence of 1 case per 1. This is the most common cause of ambiguous genitalia in a newborn girl. The diagnosis must be suspected early on and treatment instituted without delay because congenital adrenal hyperplasia can be life threatening in the newborn period. The diagnosis is based on elevated baseline and ACTH- stimulated levels of serum 1. OHP) and adrenal androgens, which are suppressed with the administration of glucocorticoids. When associated salt wasting occurs, the plasma renin- to- aldosterone ratio is also elevated. Treatment involves replacement glucocorticoids aimed at decreasing ACTH secretion (maintenance hydrocortisone at 1. Surgery for clitoral recession and vaginoplasty with correction of the urogenital sinus (usually present) may be performed in early infancy, if the degree of virilization in the newborn girl mandates it. Nonclassic form. In the nonclassic (relatively mild) form, patients present late with precocious pubarche or problems related to androgen excess, including hirsutism, menstrual irregularities, and infertility. This is said to be the most common autosomal recessive disorder in humans. The diagnosis is confirmed with elevated ACTH- stimulated levels of serum 1. OHP and adrenal androgens as in the classic form. Baseline levels are usually not as high because they are in the classic form and may even be normal. Lowered doses of hydrocortisone can be administered as treatment, although some patients never require any therapy. See Congenital Adrenal Hyperplasia for more information. IBS Diet, Irritable Bowel Syndrome Diet & IBS Recipes An estimated 15-20% of all Americans have Irritable Bowel Syndrome, or IBS, and it's a devastating, incurable. Inflamed Liver - Symptoms, Treatment, Causes, Diagnosis, Diet, Pain, Alcohol. One of the common diseases of liver is inflammation, which can be a result of an. Palpable abdominal mass. A palpable abdominal mass has a large differential diagnosis; adrenal lesions are included. Neuroblastoma is a malignant tumor derived from neural crest cells in the adrenal medulla or anywhere along the sympathetic chain. About 7. 5% of neuroblastomas arise from within the abdomen or pelvis, with half of these from the adrenal medulla itself, 2. With an overall incidence of 1 case per 1. It can manifest in numerous ways, but the most common presentation is as a fixed abdominal mass extending from the flank towards the midline. See Neuroblastoma for more information. Ganglioneuroma, the benign counterpart of neuroblastoma, can also appear as a large palpable abdominal mass. Another adrenal medullary tumor of neuroendocrine origin that can also be found in extra- adrenal sites is pheochromocytoma. This usually manifests with symptoms attributable to the excess catecholamine secretion by the tumor. In rare cases, an abdominal mass may be noted first. Adrenal cortical tumors, and especially carcinomas because these tend to be larger than adenomas, can present with a palpable abdominal mass. However, signs and symptoms of excess adrenocortical hormone secretion usually prompt a workup and diagnosis of such tumors. Adrenal cysts are rare in childhood but can be large enough to produce a palpable mass. Incidental finding of adrenal mass. An adrenal lesion may be incidentally detected during abdominal ultrasonography or CT performed for other reasons. The differential diagnosis of an adrenal mass is extensive. The differential diagnosis of an adrenal mass is as follows. Benign neoplastic conditions - Myelolipoma, ganglioneuroma, adrenocortical adenoma, hemangioma, pheochromocytoma, leiomyoma. What are the best recipes for adrenal health? Look for foods and ingredients that are nutrient dense like these 6 delicious and healthy recipes. If you suffer from hypoglycemia (irritability when hungry), if you "crash" with stress, or if you have recurrent infections that take a long time to resolve, you may.

HIV InSite's main page for treatment resources. Includes Antiretroviral Management, ARV Drug Profiles, Drug Interactions Database, ARV Alerts, U.S. Malignant neoplastic conditions - Neuroblastoma, adrenocortical carcinoma, pheochromocytoma. Hodgkin lymphoma, leiomyosarcoma, metastases (eg, malignant melanoma, breast carcinoma, hepatocellular carcinoma, squamous cell lung carcinoma). The differential diagnosis of bilateral adrenal enlargement or mass is as follows. Cushing disease. Adrenal nodular hyperplasia. Ectopic ACTH or corticotropin- releasing hormone (CRH) production. Metastases. Pheochromocytoma. Lymphoma. Hemorrhage. In adults, most incidentally discovered adrenal solid masses are adenomas; therefore, such tumors less than 4- 5 cm in size, of benign appearance on imaging, and with no extra- adrenal disease are simply observed. In children, the most common adrenal mass is neuroblastoma. In a study of 2. 6 children with an incidentally detected adrenal mass, 3. Other findings include hypertension, muscle weakness, osteoporosis, glucose intolerance, easy bruising, striae, hyperpigmentation and thin skin, menstrual irregularities, and psychiatric disturbances. Patients with cortisol excess also have impaired wound healing and an increased susceptibility to infection. The differential diagnosis of Cushing syndrome is as follows. Use of exogenous steroids. ACTH- independent causes - Adrenal nodular hyperplasia, adrenocortical adenoma, adrenocortical carcinoma. ACTH- dependent causes - Pituitary adenoma (Cushing disease), ectopic ACTH or CRH production from tumors (eg, medullary thyroid cancer, carcinoid tumor. Wilms tumor, adrenal rest tumor, pancreatic tumor). In children younger than 1. Cushing syndrome after use of exogenous corticosteroids and instead of a pituitary adenoma. In a patient with suspected Cushing syndrome, the first step is to confirm hypercortisolemia (see the image below). The best screening test is measurement of free cortisol or 1. OHCS) levels in 2- 3 consecutive 2. Normal 2. 4- hour urinary free cortisol values are in the range of 2. Plasma levels of cortisol can also be obtained. However, because of the normal diurnal variation, this test is less reliable than urine measurement. The low- dose or overnight dexamethasone suppression test should be used as a confirmatory test when 2. OHCS or cortisol are borderline. This involves PO administration of dexamethasone (3. Plasma cortisol levels are normally suppressed to less than 5 mcg/d. L. In Cushing syndrome, cortisol secretion is not suppressed. The next step is to distinguish between ACTH- dependent and ACTH- independent causes, which involve plasma ACTH level measurement. ACTH levels are normally 1. L, with a diurnal variation that parallels that of cortisol but precedes it by 1- 2 hours. However, plasma ACTH is low (< 5 pg/m. L) in patients with adrenocortical neoplasms, intermediate (1. L) in patients with pituitary adenomas and resultant adrenocortical hyperplasia, and highest (usually > 1. L) in patients with ectopic ACTH- producing tumors. To further distinguish between the causes of ACTH- dependent Cushing syndrome, the high- dose dexamethasone suppression test is used. It is based on the principle that a high dose of dexamethasone at least partially suppresses adrenal cortisol secretion secondary to an ACTH- secreting pituitary adenoma, whereas secretion secondary to adrenal tumors and ectopic ACTH production is not. Dexamethasone (1. PO divided 4 times a day . On the second day, a 2. OHCS levels. In patients with a pituitary adenoma, urinary free cortisol levels are suppressed by 9. OHCS levels are reduced to less than 3 mg/d. Another test that can be used to distinguish between Cushing disease and ectopic ACTH production is the metyrapone stimulation test. Because metyrapone blocks the enzyme 1. PO every 4 hours for 2. ACTH values. The normal response is an increase in plasma 1. L and an increase in 2. OHCS levels to twice the baseline. Patients with pituitary adenomas show this response, whereas those with ectopic ACTH secretion do not. The CRH stimulation test, whereby 1 mcg/kg of CRH is administered and ACTH levels are measured, is also performed to distinguish Cushing disease in most cases. Within 6. 0- 1. 80 minutes, patients with Cushing disease had the normal increase in ACTH, and those with other causes of hypercortisolemia do not. After these distinctions are made, imaging can be used to localize these lesions. Gadolinium- enhanced MRI of the sella turcica is the best imaging modality for assessing pituitary adenomas, with a sensitivity approaching 1. Sampling of the bilateral inferior petrosal sinuses for ACTH can help identify a pituitary adenoma if imaging does not. Thin- section high- resolution CT scanning or MRI of the adrenals identifies adrenal abnormalities with more than 9. CT or MRI of the chest and abdomen may help in identifying an ectopic ACTH- producing or CRH- producing tumor. Surgical resection of the offending lesion is the initial treatment of choice for all forms of Cushing syndrome, including bilateral adrenalectomy for bilateral nodular adrenal hyperplasia, transsphenoidal partial hypophysectomy for pituitary adenomas, and unilateral adrenalectomy for adrenal tumors. Mineralocorticoid excess. Presenting features of mineralocorticoid excess include hypertension, headache, tachycardia, fatigue, proximal muscle weakness, polyuria, and polydipsia. The differential diagnosis of hyperaldosteronism is as follows. Primary - Idiopathic adrenal nodular hyperplasia (idiopathic hyperaldosteronism), glucocorticoid- suppressible hyperaldosteronism, adrenocortical adenoma, adrenocortical carcinoma. Primary hyperaldosteronism, characterized by elevated plasma aldosterone, low plasma renin levels, hypokalemia, and hypertension, is rare in children.
