Elevated Plasma Renin Activity Caused by Accelerated-malignant Hypertension in a Patient with Aldosterone-producing Adenoma Complicated with Renal Insufficiency

抄録

During the malignant phase of hypertension in patients with primary aldosteronism complicated with severe renal failure, the plasma renin activity may markedly increase with a false negative screening result for primary aldosteronism, thus potentially leading to a missed diagnosis of primary aldosteronism. We herein report the case of 37-year-old man who presented with accelerated-malignant hypertension complicated with severe renal insufficiency. The plasma renin activity was markedly increased in the malignant phase of hypertension, which were atypical results for primary aldosteronism. However, a plain abdominal computed tomography scan revealed a left adrenal nodule, which was diagnosed as aldosterone-producing adenoma by adrenal venous sampling.
