[Conn's adenoma as a cause of hypertension].

: The authors describe two observations of primary hyperaldosteronism, caused by a cortical adrenal adenoma (Conn's adenoma). Both patients were treated by unilateral adrenalectomy from lumbotomy. (In the second patient subtotal resection). The problem is discussed from the aspect of morphological diagnosis and location with emphasis on the primary importance of CT. The surgical operation is aimed and simple without the necessity of peroperative confirmation of the morphological background of the syndrome.
