Investigation showed hypokalemia and kaliuresis without pronounced suppression of plasma renin activity or elevation of urinary aldosterone excretion. There was biochemical evidence of catecholamine metabolite excess but the usual clinical features of pheochromocytoma were absent. Laparotomy revealed a pheochromocytoma and adrenal adenoma in the right adrenal gland. Excision of the tumours was followed by resolution of the hypertension and metabolic abnormalities.
