Aneurysms of the pulmonary artery. Radiographic manifestations.

We analyzed the radiographic manifestations of aneurysms of the pulmonary artery in a retrospective study of 16 patients. The location, shape, size, and number of these lesions were assessed. Pulmonary artery aneurysms can be fusiform or saccular, central or peripheral, solitary or multiple. Many disease processes can lead to aneurysm formation. Correct diagnosis of these vascular lesions is important for patient management.
