Microdissected zona glomerulosa adjacent to an aldosterone producing adenoma Preoperative diagnosis of primary hyperaldosteronism by increased aldosterone, increased aldosterone to renin ratio, lateralisation of the aldosterone to cortisol ratio after adrenal venous sampling. Histological confirmation of a unique 10 mm adenoma; no hyperplasia of the adjacent zona glomerulosa. Microdissection on fresh tissue with a forceps after fat cleansing: the glomerulosa comes with the adrenal capsule. Keywords = adrenocortical adenoma aldosterone
