[MacLeod's syndrome: nosographic framework in the area of diffuse diseases of the lung. Contribution of radiographic and radioisotope studies].

The paper examines the clinical and etiopathogenetic aspects of MacLeod's syndrome. MacLeod's syndrome, more accurately known as unilateral bullous pneumodystrophy, forms part of the diffuse or localised hyperdiaphanies of the pulmonary parenchyma. Standard chest examination, inhalation and exhalation chest X-rays and stratigraphic control are useful instruments for the etiopathogenetic study of the syndrome. More specific tests include perfusion and ventilation scintigraphy, in addition to bronchography and angiopneumography.
