title: A giant main pulmonary artery aneurysm associated with infundibular pulmonary stenosis.
abstract: We report a case of a giant pulmonary artery aneurysm associated with infundibular pulmonary stenosis. Echocardiography disclosed markedly enlarged main pulmonary artery, but no left to right shunt flow at levels of the atrial septum, ventricular septum and the pulmonary artery. Continuous wave Doppler revealed a maximum velocity of 1.5 m/s which corresponded to the pressure gradient between the right ventricle and the pulmonary artery of 9.5 mmHg. Contrast-enhanced multidetector-row computed tomography with a 16-slice scanner revealed pulmonary artery aneurysm with the maximum diameter of 67 mm on axial image.
