title: Hypermineralocorticism without elevation of plasma aldosterone: deoxycorticosterone-producing adrenal adenoma and hyperplasia.
abstract: Two female patients were admitted for evaluation of hypertension and hypokalaemia. Plasma renin activity was suppressed and plasma aldosterone levels were within the normal value in a 52-year-old woman and below the normal value in the other patient, a 62-year-old woman. Plasma 11-deoxycorticosterone (DOC) levels were as high as 1.13 and 1.47 nmol/l, respectively. Adrenal scintigram and abdominal CT scan clearly showed a right adrenal tumour in the 52-year-old woman. After adrenalectomy plasma DOC level decreased to the normal level of 0.12 nmol/l, and her blood pressure and serum potassium became normal. Abdominal CT scan revealed no finding of adrenal tumour in the older woman. These results indicate that these two patients had hypermineralocorticism with elevation of plasma DOC. One patient had a DOC-producing adrenal adenoma, and the other probably had bilateral adrenal hyperplasia.
