This abnormality is a paraneoplastic syndrome (i.e. caused by hyperplasia or tumors). About 35% of the cases are caused by a single aldosterone-secreting adenoma, a condition known as Conn's syndrome. [7] [8] Many patients experience fatigue, potassium deficiency and high blood pressure which may cause poor vision, confusion or headaches.
Functional adrenocortical adenomas demonstrate symptoms consistent with mixed endocrine syndromes. In most reported cases of adrenocortical adenoma, patients have presented with one or multiple endocrine syndromes such as hyperaldosteronism / Conn's Syndrome , [ 3 ] hypercortisolism / Cushing's syndrome , [ 4 ] hyperandrogenism / feminization ...
Conn's syndrome is primary hyperaldosteronism caused by an aldosterone-producing adenoma. Depending on cause and other factors, hyperaldosteronism can be treated by surgery and/or medically, such as by aldosterone antagonists .
Adrenocortical carcinoma (ACC) is an aggressive cancer originating in the cortex (steroid hormone-producing tissue) of the adrenal gland.. Adrenocortical carcinoma is remarkable for the many hormonal syndromes that can occur in patients with steroid hormone-producing ("functional") tumors, including Cushing's syndrome, Conn syndrome, virilization, and feminization.
Secondary hyperaldosteronism (also hyperreninism, or hyperreninemic hyperaldosteronism) is due to overactivity of the renin–angiotensin–aldosterone system (RAAS).. The causes of secondary hyperaldosteronism are accessory renal veins, fibromuscular dysplasia, reninoma, renal tubular acidosis, nutcracker syndrome, ectopic tumors, massive ascites, left ventricular failure, and cor pulmonale.
The genetic conditions such as Liddle's syndrome and congenital adrenal hyperplasia present in childhood or earlier in life than the acquired causes which can present at any age. [1] [4] [2] Adult patients present with clinical history of resistant hypertension despite typical medical therapy and lifestyle changes.
Liddle's syndrome, also called Liddle syndrome, [1] is a genetic disorder inherited in an autosomal dominant manner that is characterized by early, and frequently severe, high blood pressure associated with low plasma renin activity, metabolic alkalosis, low blood potassium, and normal to low levels of aldosterone.

Mineralcorticoid excess due to a disease state such as Conn's syndrome usually does not lead to hypernatremia unless free water intake is restricted. Salt poisoning is the most common cause in children. [16] [17] It has also been seen in a number of adults with mental health problems. [11] Too much salt can also occur from drinking seawater or ...
