Abstract

The purpose of this article is to report two cases of pulmonary artery (PA) aneurysm in patients who had no evidence of left-to-right intracardiac shunting or other known relevant etiologies.

In both women, chest radiographic findings of a hugely dilated PA were confirmed by computed tomography (CT). In both cases, a ventriculogram showed fusiform dilatation of the main PA without evidence of pulmonary valve stenosis. The results of chest radiography, two-dimensional echocardiography, CT of the thorax, including pulmonary angiography in one patient, were compatible with the diagnosis of PA aneurysm. No specific drug regimen was administered nor was any surgical intervention performed in either patient. Both patients were asymptomatic as of the last telephone follow-up. Idiopathic PA aneurysm is a benign condition with better survival than PA aneurysms of other etiologies, because of the absence of left-to-right intracardiac shunting and significant pulmonary hypertension. PA aneurysm must be considered as part of the differential diagnosis in...Continue Reading
