Abstract

<jats:title>Abstract</jats:title> Renovascular hypertension (RVHT) is an important and potentially treatable form of resistant hypertension. Hypercortisolemia could also cause hypertension and diabetes mellitus. We experienced a case wherein adrenalectomy markedly improved blood pressure and plasma glucose levels in a patient with RVHT and subclinical Cushing's syndrome. A 62-year-old Japanese man had been treated for hypertension and diabetes mellitus for 10 years. He was hospitalized because of disturbance in consciousness. His blood pressure (BP) was 236/118 mmHg; pulse rate, 132 beats/min; and plasma glucose level, 712 mg/dl. Abdominal computed tomography scanning revealed the presence of bilateral adrenal masses and left atrophic kidney. Abdominal magnetic resonance angiography demonstrated marked stenosis of the left main renal artery. The patient was subsequently diagnosed with atherosclerotic RVHT with left renal artery stenosis. Bilateral adrenal masses were immunohistologically identified as potential sites for cortisol overproduction. Therefore, laparoscopic left nephrectomy and adrenalectomy were simultaneously performed resulting in improved BP and glucose levels. Pathological studies revealed the presence of multiple cortisol-producing adrenal nodules and aldosterone-producing cell clusters in the adjacent left adrenal cortex. In the present case, activated renin-angiotensin-aldosterone system and cortisol overproduction resulted in severe hypertension, which was managed with simultaneous unilateral nephrectomy and adrenalectomy.
