1/8. Malignant hypertension and hypertensive encephalopathy in primary aldosteronism caused by adrenal adenoma.

    Two cases are reported as follows: 1) 1 female patient with accelerated-malignant hypertension secondary to an aldosterone-producing adrenal adenoma; and 2) 1 female patient with adrenal adenoma, severe hypertension, and hypertensive encephalopathy. This association is a rare clinical finding, and malignant hypertension may modify the hormonal characteristic of primary aldosteronism, making its diagnosis more difficult. The diagnosis of primary aldosteronism should be considered in patients with malignant hypertension or hypertensive encephalopathy if persistent hypokalemia occurs. Identification of primary aldosteronism is of paramount importance for the patient's evolution, because the surgical treatment makes the prognosis more favorable.

2/8. High-renin malignant hypertension secondary to an aldosterone-producing adenoma.

    Malignant hypertension and high plasma renin activity was found in a 39-year-old woman with an aldosterone-producing adenoma. Only 3 similar cases have been previously reported, and all patients died before or after identification of the adenoma. The present paper documents the first reported case of a successfully managed high-renin malignant hypertension secondary to an aldosterone-producing adenoma. Regardless of its sporadic occurrence and common presence with low plasma renin activity, primary aldosteronism should be considered as a possible underlying cause of high-renin malignant hypertension.

3/8. Autonomous aldosterone-secreting ovarian tumor.

    The case of a young woman with primary aldosteronism originating extraadrenally--ovarian tumor--is reported. Clinically she presented with uncontrolled hypertension. Biochemical and hormonal profiles showed features of aldosteronism. The primary was found in the left ovary. Following excision of the tumor, aldosteronism regressed completely. Microscopically, the tumor was of the lipid cell type. Nine months after surgery she is asymptomatic and well. review of the literature uncovered three previous reports of aldosterone-secreting ovarian tumors.

4/8. The simultaneous occurrence of renal artery stenosis and an aldosteronoma in a patient with hypertension.

    The simultaneous occurrence of renovascular hypertension and an adrenocortical adenoma is a rare entity. The case of a 64-year-old woman who underwent an aortorenal bypass graft for renovascular hypertension requiring a multidrug antihypertensive regimen is presented. Persistently elevated blood pressures in the postoperative period prompted further workup for other causes of hypertension. Laboratory evaluation showed hyperaldosteronism and hyporeninemia despite enalapril administration. Abdominal computerized tomography (CT) revealed a left adrenal mass which, on surgical removal, was found to be a cortical adenoma. Subsequently, her antihypertensive therapy has been reduced to a single agent. Previous authors have described only four patients with malignant hypertension who had the rare clinical combination of renal artery stenosis and an aldosteronoma. This case reemphasizes the critical need for a thorough search for other surgically correctable lesions in those patients who remain severely hypertensive after the "definitive" operation.

5/8. Malignant hypertension due to an aldosterone producing adrenal adenoma.

    Malignant hypertension in Conn's syndrome is rare. We report an 18 year old boy who presented with visual and renal impairment due to malignant hypertension which subsequently proved to be secondary to an aldosterone secreting adrenal adenoma. diagnosis was delayed in this patient as plasma renin concentrations (PRC) were not invariably low and it is emphasized that suppression of PRC is not always a feature of primary hyperaldosteronism. The diagnosis of primary hyperaldosteronism is only excluded adequately by the demonstration of suppression of aldosterone secretion.

6/8. hypokalemia secondary to primary hyperaldosteronism in a renal transplant recipient.

    We describe a patient who developed persistant hypokalemia after renal transplantation that was initially attributed to diuretics and/or steroids. However after stopping the diuretic, the patient continued to have urinary losses of potassium (less than 30 mEq/day) at a time when the serum potassium was only 2.4 mEq/l and high urinary chloride (33 mEq/day) suggesting that the diuretics were not responsible for the hypokalemia and the metabolic alkalosis. The results of these simple laboratory tests and the presence of persistent severe hypokalemia prompted additional studies (peripheral renin activity; plasma aldosterone levels; and CT scan) that led to the diagnosis of left adrenal gland adenoma. Surgical removal of the adrenal adenoma led to the normalization of the serum potassium and a fall in the total CO2 content in plasma. To our knowledge this is the first report of a case of hypokalemia secondary to primary hyperaldosteronism in a renal transplant recipient.

7/8. Malignant hypertension in association with primary aldosteronism.

    Primary aldosteronism is associated with low plasma renin levels, whilst malignant phase hypertension is generally associated with raised renin activity. These two conditions are therefore at opposite ends of the renin spectrum, so in theory their co-existence would be unusual. We describe in detail 3 cases of primary hyperaldosteronism from a disease register of 315 cases of malignant hypertension seen in one medical centre over 29 years.

8/8. Malignant hypertension in a patient with primary aldosteronism with elevated active renin concentration.

    A 40-year-old male, with a past history of hypertension but receiving no medical treatment, was referred. He manifested malignant hypertension (190/130 mmHg; Keith-Wagener III), renal dysfunction (serum creatinine, 3.8 mg/dl), and elevated plasma aldosterone (450 pg/ml) and active renin concentration (ARC, 104 pg/ml). His blood pressure was controlled with multiple antihypertensive agents and ARC thus decreased (4.3 pg/ml), but aldosterone remained elevated. Abdominal magnetic resonance imaging (MRI) revealed a right adrenal adenoma, and aldosterone-producing adenoma was confirmed by adrenal venous sampling. Primary aldosteronism very rarely develops to malignant hypertension, and even in that case ARC is suppressed. Therefore this is a rare case of primary aldosteronism complicated with malignant hypertension and high ARC.
