Imaging exams displaying the pulmonary aneurysm and associated features. A) Chest radiograph (posteroanterior view) shows cardiomegaly, dilated main pulmonary artery and right pulmonary artery. B) Ecocardiography: paraesternal view, at great vessels level. Color-Doppler shows severe pulmonary regurgitation. C) Multislice contrast computed tomographic scan of the thorax on axial projection shows a close contact of the main pulmonary artery to the chest wall, dilated main pulmonary artery and both of its branches which have a fusiform morphology. D) On sagital projection the widest diameter of the aneurysm can be measured.
