It is not uncommon for adults to have bilateral sources of aldosterone hypersecretion in the presence of a nonfunctioning adrenal cortical adenoma, making adrenal venous sampling (AVS) mandatory in cases where surgery is being considered. For cases where AVS is unable to provide lateralisation of the source/sources of aldosterone hypersecretion, radionuclide imaging such as NP-59 scintigraphy or PET/CT with 11C-Metomidate is an option. Since 11C-Metomidate is unspecific for CYP11B1/CYP11B2 the patient needs pre-treatment with dexamethasone to downregulate the expression of CYP11B1.The diagnosis is best accomplished by an appropriately-trained subspecialist, though primary care providers are critical in recognizing clinical features of primary aldosteronism and obtaining the first blood tests for case detection. Classification
Some people only use Conns syndrome for when it occurs due to an adrenal adenoma (a type of benign tumor). In practice, however, the terms are often used interchangeably, regardless of the underlying physiology. Differential diagnosis
Primary hyperaldosteronism can be mimicked by Liddle syndrome, and by ingestion of licorice and other foods containing glycyrrhizin. In one case report, hypertension and quadriparesis resulted from intoxication with a non-alcoholic pastis (an anise-flavored aperitif containing glycyrrhizinic acid). Treatment
The treatment for hyperaldosteronism depends on the underlying cause. In people with a single benign tumor (adenoma), surgical removal (adrenalectomy) may be curative. This is usually performed laparoscopically, through several very small incisions. For people with hyperplasia of both glands, successful treatment is often achieved with spironolactone or eplerenone, drugs that block the aldosterone receptor.
