[Valuation of the methods of investigation in topographic diagnosis of Conn Adenoma (author's transl)].

Five case of primary aldosteronism are reported. The authors analyse the place of each method able to localize adenoma: arteriography, phlebography and scintigraphy. Even if adrenal gland phlebography is faithful, it can involve hemorrhage. Then it is quite sure that scintigraphy will be soon able to take her place. The surgical approach must be performed on both sides. The authors describe an original exposure of left adrenal gland through anterior incision.
