    Abstract:
    Seven cases of primary aldosteronism were experienced during the 12 years in the Toyama Medical and Pharmaceutical University Hospital. The majority of cases were between 32 and 64 years old with a mean of 51 years. Two cases were male and 5 were female. Hypertension was observed in 6 cases, but one case had normal blood pressure. Hypokalemia was recognized in 6 cases. The plasma level of aldosterone was high in all cases and all the cases showed low levels of plasma renin activity. Concerning the localization of the lesions, CT scan, magnetic resonance imaging and adrenal scintigraphy revealed an accuracy rate of 100%, each. Therefore, these imaging techniques are very useful tools for identifying the locality of the adenoma. On the other hand, the accuracy rates of adrenal venous aldosterone assay and ultrasonography were 83 and 60%, respectively. The cases with rather short duration of hypertension before surgery returned to normal in blood pressure earlier after the operation than the other cases.
