An electrocardiogram showed sinus rhythm with right bundle branch block (Fig. 1).
Chest radiograph shows cardiomegaly, dilated main and left pulmonary artery with peripheral pruning.

Chest radiography revealed cardiomegaly, severe dilation of the main pulmonary artery, and dilation of the pulmonary branch arteries (Fig. 2).
(A) An huge pulmonary artery aneurysm seen in parasternal short axis. (B) A shunt between pulmonary artery and descending aorta
seen with color Doppler.

Transthoracic echocardiography showed an aneurysm of the main pulmonary artery of approximately 7.4 cm, dilation in left and right pulmonary arteries, and a turbulent flow between the pulmonary artery and descending aorta with color Doppler (Fig. 3A-B).
(A) Moderate degree tricuspit regurgitation with pulmonary arterial systolic pressure 110 mmHg and dilatation in right heart chambers.
(B) Pulmonary valve with three cusps in the parasternal long axis.

Pulmonary valve, in parasternal long axis, was seen as it were tricuspid aortic valve that was classically observed in parasternal short axis view (Fig. 4A-B).
(A) Contrast enhanced multislice chest CT (B) three-dimensional reconstruction of it revealing diffuse aneurysmal dilatation of the
pulmonary artery and patent ductus arteriosus.

Contrast-enhanced, multislice computed tomography (CT) with 3 dimensional reconstruction of the patient's chest revealed a giant aneurysm of the pulmonary trunk with a maximum diameter of 79 mm and a patent ductus arteriosus (PDA) (Fig. 5A-B).
