Because of the intimate relation of the artery to the heart and the mediastinal structures, recognition of these changes in roentgenologic study of the pulmonary artery has hitherto been difficult. Groedel's careful description of a probable aneurysm of the pulmonary artery1 demonstrates convincingly the difficulties presented to the roentgenologist in the anatomic diagnosis of pathologic conditions of the pulmonary artery. With the presentation, in 1938, by Robb and Steinberg,2 of a practical method of visualization of the cardiovascular system with contrast medium, the entire bed of the pulmonary artery became readily accessible to roentgenologic examination. Angiocardiography has indicated a wide variety of pathologic states which are manifested, in part, in abnormalities of the pulmonary artery.
