[Diagnostic possibilities of computerized tomography in primary hyperaldosteronism (author's transl)]

In 20 patients with a clinical picture of primary hyperaldosteronism (5 patients were later found to be suffering from hypertension of other origin), CT showed diagnostic precision higher than 90% in the localization of adrenal adenoma (11 out of 12). On the other hand, this examination scarcely helped in the diagnosis of uncommon gland hyperplasias (1 out of 3). In CT doubtful or negative cases, hormonal measurement in blood samples taken selectively from adrenal veins was more indicative than selective phlebography. CT can therefore be considered as an alternative to iodocholesterol scintigraphy in early diagnostic investigation in this field of pathology.
