title: [Diagnostic possibilities of MR-tomography of the adrenals of patients with essential hypertension].
abstract: MR-tomography was employed for examination of 41 patients with arterial hypertension (AH). Aldosteroma was diagnosed in 11 patients, pheochromocytoma in 4 patients, paraganglioma in one patient. 25 patients with essential hypertension (EH) were entered into the comparison group and 16 healthy persons into the control group. Computerized tomography of the adrenals was performed in all the examinees. In MR-tomography normal adrenals were visualized as homogeneous formations of low intensity image surrounded by high intensity image of the retroperitoneal fat. In the patients with stage I-IIA EH adrenal shape and sizes did not differ from those in the control group. Certain enlargement and deformity of the adrenals were noted in the patients with stage IIB-III EH, especially in a malignant course of disease. Aldosteroma on MR-tomograms was visualized as an additional formation in the adrenal field, had a rounded or oval shape with regular clear contours; by intensity of image the tumor was similar to the liver. In the pheochromocytoma patients the tumor was also of a rounded shape, not always with clear borders, in one case with signs of the penetration in the vena cava inferior which was clearly visualized on the frontal sections. Paraganglioma found in one patients in the hilus of the left kidney, was of an oval shape with a high intensity signal, similar to that from the sympathetic chain. A study conducted in 3 reciprocally perpendicular planes clearly showed that the tumor adjoining the aorta was unconnected with the renal vessels.
